       GENERAL PROCEDURE FOR "HOOKING-UP" BEFORE A TRIP

    The following steps are suggested as a check list before
    starting on your trip with your Avion Coach.

    1.  See that all clothing, dishes. golf clubs, fishing
	gear etc. are properly stored.  Heavy gear should be
	located near the floor and as near to the center of
	the trailer as possible.  It is wise to use square
	plastic containers in your refrigerator.  DON'T leave
	ice cubes in the freezer compartment, unless your
	refrigerator has an ice water drain lose or is gas
	operated, while traveling.  Pack rolled towels in front
	of containers in refrigerator so they won't move about
	or spill over.  Unless you plan extended stays, far off
	the beaten path, there is no need to store up on food.

    2.  Be sure all drawers, cupboards, and closet doors are
	securely latched.  the drawers in your Avion Coach are
	notched on the bottom slide edge, this notch prevents
	the drawers from opening while traveling.  It is import-
	ant that you form the habit of lifting and pulling as
	you open a drawer.

    3.  Radio, television, books, folding chairs, etc. should NOT
	be place on top of beds while traveling.  The jiggling
	of the mattress and springs has a tendency of moving
	everything forward and if you use a quick brake this
	will throw everything off the beds onto the floor.  Place
	radios, T.V., vases, etc. in boxes, pack carefully and
	place on floor in center of trailer.

    4.  If your utilities are hooked up, disconnect electric
	at the meter and then at trailer, flush toilet and if
	your trailer does not have pressure water system
	open all faucets to drain water system.  If your trailer
	has a pressure water system see instruction in this
	booklet for filling, draining, and proper use of pressure
	water system.  Disconnect sewer and water hose and store
	after they are completely drained.

    5.  Close all windows, ventilators, and lock exterior door.
	At times while traveling on extremely dusty roads, it is
	advisable to leave the front roof vent open slightly.
	This has a tendency to create an air pressure inside of
	the trailer and prevent dust from filtering into the trailers.

    6.  Remove stabilizing jacks or blocks from under the coach.
	(stabilizing jacks for Avion Coaches should be placed
	under the frame at the front and tear of trailer.
	CAUTION:  NO NOT place stabilizing jacks or blocks under
	aluminum under-belly skin.  DO NOT use jacks to level the
	trailer.  Level the trailer by driving up on boards or
	backing into holes.  The and only then use stabilizer
	jacks to stabilize the coach

    7.  Hook-Up.  Raise the front of the coach with the post jack,
	have your partner back the car into place.  We find the
	best system of signals to be "clock-wise" or "anti-clock-
	wise and about two feet, now about two inches" and so on.
	until the car is in position.  Lower the front end of the
	coach so that the ball and socket are together.  Move the
	car back and forth a little to be sure they are together,
	then put the ball lock in place.  It is important to
	secure this lock by placing a small lock or pin through
	the eyelet back of the latch.  Jack the front of the
	coach up again (the car will come up with it) and put on
	the hitch and adjust for straight line in both units.
	Lower the coach onto the hitch.  Hook-up the electric
	connection from car to coach.  Hook-up safety chin.  It
	is advisable to use an equalizer type hitch.  Make all
	adjustments according to hitch manufacturers instructions.

    8.  Check brakes and lights.

    9.  Re-heck all previous steps and be sure you leave your
	parking area clean.

	this information is general and normally may prove help-
	ful to the novice trailerite.  Most experience trailer
	travelers have their own pet way of doing most of these
	steps.

				IMPORTANT

	The 2 5/16 in. hitch ball should be mounted on your car
	so that the top of the ball is 20 in. from the ground.  At
	this height and with an equalizer type hitch property ad-
	justed your Avion will ride level.  With a single axles
	trailer it is not necessary that the trailer ride perfectly
	level to tow properly.  We recommend that the trailer and
	car ride level for appearance sake.

	With a tandem axle trailer it is absolutely necessary that
	the trailer ride level so that each axle will carry the
	same load.  If the trailer is not level you will exper-
	ience a "fish-tailing" or swaying while traveling.
	The wheel bearing should be packed with grease every
	10,000 miles.

	You must produce a defective tire for inspection if you
	expect to get an adjustment from your Armstrong distributor.
	Do not throw a defective tire away until such inspection
	has been made   The Avion Service Corporation is authorized
	to adjust Armstrong Tires.

	Do not travel with a sewer hose connection (elbow or nipple)
	inserted in the drain manifold of the trailer.  Serious
	damages to the drain system or toilet installation may re-
	sult if the sewer hose connection is not removed for this
	hose connection will scrape the pavement when entering or
	leaving a gas station or similar entrances.

	IMPORTANT INSTRUCTIONS FOR WINTERIZING YOUR AVION

    1.  Level the coach.

    3.  Open the petcock on the inlet faucet on outside of coach.

    3.  Open all faucets on the inside of the coach and remove
	filler cap from the water tank.

    4.  Open the valve in the line from the water heater through
	the floor of the trailer to drain the water tank.

    5.  Open the bowl filler valve on the toilet and hold open
	for 15 to 20 seconds.  It is most important that you
	drain this valve

    6.  If you coach is equipped with a septic tank, open the
	septic tank valve.  Fill the toilet bowl and release with
	foot lever.

    7.  Work the foot pedal of the toilet up and down several times.

    8.  Open wash basin faucet and drain water out of the shower
	spray hose by raising it above the faucet.

    9.  Raise the front end of the trailer as high as it will go by
	cranking the jack all the way up and allow to drain, then
	crank jack to lowest position and allow to drain.  Return to
	level position.

   10.  Use suction pump to remove water from taps or pour about
	one (1) cup of permanent type anti-freeze in each of the
	three traps--one in the kitchen sink, one in the bathroom
	sink, and one in the bathtub, using caution not to spill
	any on plastic bathtub where discoloration may take place.
	(Caution:  do not use alcohol base anti-freeze.)

   11.  If your trailer is equipped with a purifier, remove the
	cartridge and place in heated area until spring.

   12.  CAUTION--before traveling, you should either flush out the
	bathrub drain, or place the plug in position and tape down,
	so that the alcohol will not spatter on the tub.

   12.  If your coach is equipped with a water tank you can blow the
	lines out by putting 75 lbs. of pressure in the tank and
	opening the drain valves and faucets one at a time.  However,
	this procedure should not be necessary but may be done for
	additional Protection.

                        CARE OF THE EXTERIOR

    If you should travel with your coach on road that were chlorided
    or salted to melt ice, it is suggest that the chloride be washed
    off the trailer as soon as possible.

    A very light wiping with a soft cloth with a straight back and
    forth motion while hosing will remove the chloride, which if left
    on might cause discoloration.

    The use of a mild soap or detergent will aid in the removal of
    road file.  Never use a strong alkali or abrasive.

    The sealer for all exterior seams of your Avion carries the brand
    name of Ten-X (mfg. by Electro Cote Company, Minneapolis, Minne-
    sota) and can be purchased from most trailer dealers and automo-
    supply stores.

    Exterior seams should be examined periodically for holes or shrink-
    age of the sealer caused from long exposure to the elements

 			  TRAILER INTERIOR

    The paint used on the interior walls of your Avion is of a high
    industrial grade and can be cleaned occasional with a mild soap
    or detergent and warm water.

    The identifying numbers of this paint manufactured by Sherwin
    Williams, are #E63W3 white primer and #L66W42 ripple.

				TIRES

   Your Avion is equipped with Armstrong Nylon Tires.  These are rated
   to carry the weight of your Avion plus ample allowance for cloths,
   dishes and personal items.  For maximum load carrying capacity,
   your tires should be inflated to 45 lbs. in a 7.00 x 15 6 ply;
   60 lbs. in a 7.00 x 15 8 ply; and 75 lbs. in a  7.50 x 15 10 ply.
   If you should require an adjustment on a faulty or defective tire
   secure the name of your nearest Armstrong distributor from the list
   in the back of this book.  Take the defective tire to the distri-
   butor and he will make an adjustment according to the terms and
   conditions of the Armstrong guarantee.

   this tank the different ways listed below:

	1.  Apply one end of a hose to the hose connection on the
	trailer (left front underneath) and the other end of hose to a
	pressure water supply.  make sure all faucets in the trailer
	are closed and open the valve on the trailer where the hose in

				- 5 - 




Page 6



   connected.  Open the hot water tap on the kitchen sink and
   the valve on the supply.  When water starts to flow out of the
   hot water faucet at the kitchen sink in a steady stream close
   the faucet and allow the water to run into the tank until it
   stops running.  Close the valve on the trailer and at the
   supply.  Remove the hose.  You will have a tank 3/4 full of
   water under pressure equal to that of the supply source.

   2.  The second method of filling the tank is as follows:
   Remove the cap on the filler spout and pour water in until it
   overflows.  Close all faucets in the trailer, replace the
   filler spout cap and put pressure in the tank by using a hand
   pump or a service station air supply hose.  Re recommend a
   maximum of 60 lbs. pressure-10 to 15 lbs. is ample to supply
   water at all faucets.  The air valve will be found on the
   filler spout.

   During hot weather do not turn the thermostat to highest
   position.  If the unit is turned on high in hot weather it will
   freeze and then begin to defrost and will not freeze again
   until it is turned off and the unit is allowed to cool.

   The thermostat should be set on normal during hot weather.

   If you Avion is used when the outside temperature is below
   freezing the exterior louvered door should be covered.  This
   can be done with an ordinary piece of cardboard.  Open louver-
   ed door, fit cardboard on inside of door and then close door.
   (CAUTION:  be sure to remove this cover when using refrigerator
   in warm weather).


   When a gas tank is going empty your refrigerator might not
   freeze properly, this is due to a lack of pressure.  Your gas
   burner will be operating but not with a sufficient heat to
   operate the refrigerating unit properly.  when your gas tank is
   going empty the gas will burn with a smell similar to a gas
   leak.  Change tanks and refill.

   for service of your Norcold refrigerator contact either Norcold
   Inc., 16200 S. Maple Avenue, P.O. Box 250, Gardena, California.
   Phone FAculty 1-9300 or Florence Dist. Co., 2900 W. Mishawaka
   Road, Elkhart, Indiana, Phone Jackson 34510.

   			SEPTIC TANK

   If your trailer is equipped with Avion fiber glass sewage
   waster storage tank, please follow these recommendations for
   using same.

   To retain waste (from toilet only) close the holding tank
   valve.  This valve is located outside at the sewer outlet
   at the rear left, up against the floor of the trailer.  It is
   operated as follows:  To close the valve push the small black
   knob forward (toward the front of the trailer) as far as it
   will go.  Twist the clack know clockwise until it become tight.
   The valve is now in a closed position.  To open the valve twist
   the black know several turns in a counter-clockwise direction
   and pull back.  it should pull back about 4".  It is now in an
   open position.  Keep the shaft of this valve lubricated for
   easy operation.

   Only the waster from the stool goes into your sewage storage
   tank.  It is recommended that this tank be given a rinsing as
   often as possible.  When in park with water and sewer connec-
   tins, run water into toilet bowl and keep flushing with
   pedal in down position.

   The waste water from shower and sink drains does not go into
   the holding tank.

			WATER PURIFIER (5/21/64)

   If your coach is equipped with an Ogden water purified it will
   be located to the left in back of the kitchen sink.  This puri-
   fier is designed to remove harmful bacteria, odor, and impuri-
   ties from your drinking water.  The filter should be changed
   when the water begins to run slowly from the filter unit.

   The replacement packs #SM1 are available direct from Western
   Ogden Purifier Co. at 7906 Santa Monica Blvd., Hollywood 46,
   California or from the Avion Service Corporation.

   when the water begins to run slowly.  The filter pack for this
   unit is "U-fil #150" and is available from the Ewert Trailer
   Products, 211 Edgemont Lane, Hoffman Estates, Roselle, Illinois
   60173, or from the Avion Service Corporation.

   Filter packs should be removed when winterizing the trailer.

			12 VOLT SYSTEM

   If your Avion is equipped with a 12 volt system. you will find
   the following equipment:   a 12 volt battery mounted in a case
   behind the gas bottles, a fuse box and batter charger under
   the shelf under front window inside of trailer, a 12 volts and
   110 volt fixture over the sofa or dinette, a 12 volt 110 volt
   fixture over the sink, a 12 volt 110 volt fixture over each
   bed or over one bed and vanity in a double bed model, a 12 volt
   110 volt fixture in the bathroom with a 12 volt 110 volt fan on
   the heater.  There will be two power fans that operate off the
   12 volt battery only -- they can be operated indefinitely when
   you have 110 volt power because the battery charger will keep
   the battery supplied with current.  One fan will be located in
   the front roof vent, another in the range. hoods.

   The 12 volt power should be used sparingly and equipment turned
   on only when being used (don't leave lights on in areas where
   no one is present, etc.) when 110 power is not available.

   Charger will charge average battery in approximately 3 to 4
   hours.  When charge is completed, the high charge rate will
   automatically shut off and turn on a trickle charge which will
   remain "on" until charger is disconnected.  Trickle charge may
   ]be left "on" for an indefinite period as long as cells have
   sufficient water in them.  The reset charging rate, remove both
   battery clips and AC plug, then reconnect charger.

   If the trailer is to be stored for several months without being
   hooked up to 110 volt power on e of the charge cables should be
   disconnected from a battery terminal making sure to connect it
   back up when trailer is again used.

 			CARE OF THE EXTERIOR

    If you should travel with your coach on road that were chlorided
    or salted to melt ice, it is suggest that the chloride be washed
    off the trailer as soon as possible.

    A very light wiping with a soft cloth with a straight back and
    forth motion while hosing will remove the chloride, which if left
    on might cause discoloration.

    The use of a mild soap or detergent will aid in the removal of
    road file.  Never use a strong alkali or abrasive.

    The sealer for all exterior seams of your Avion carries the brand
    name of Ten-X (mfg. by Electro Cote Company, Minneapolis, Minne-
    sota) and can be purchased from most trailer dealers and automo-
    supply stores.

    Exterior seams should be examined periodically for holes or shrink-
    age of the sealer caused from long exposure to the elements

 			  TRAILER INTERIOR

    The paint used on the interior walls of your Avion is of a high
    industrial grade and can be cleaned occasional with a mild soap

 			   WATER HEATERS

    If you coach is equipped with an electric water heater it will
    be a Tradon electric water heater.

    DO NOT leave the heater turned on unless you have a water
    supply to the heater (either a hose supply or a pressure
    water system supply.

    If you coach is equipped with a gas water heater it will be
    located on the left side of the trailer.  To light the heater
    you must remove the lower panel of the heater on the outside
    of the coach.  This panel may be removed by turning the two
    (2) winged screws at the bottom edge of the panel.  Open the
    gas shut off valve in the lower left corner and follow the
    instructions for lighting as listed on the tag inside of the
    heater.

    For service under the terms of the Bowed warranty contact one
    of the authorized Bowed Service Centers as listed in the back
    of this book.  For service of an electric water heater contact
    Tradon Engineering, Marshall, Michigan.

   			   12 VOLT SYSTEM

   If your Avion is equipped with a 12 volt system. you will find
   the following equipment:   a 12 volt battery mounted in a case
   behind the gas bottles, a fuse box and batter charger under
   the shelf under front window inside of trailer, a 12 volts and
   110 volt fixture over the sofa or dinette, a 12 volt 110 volt
   fixture over the sink, a 12 volt 110 volt fixture over each
   bed or over one bed and vanity in a double bed model, a 12 volt
   110 volt fixture in the bathroom with a 12 volt 110 volt fan on
   the heater.  There will be two power fans that operate off the
   12 volt battery only -- they can be operated indefinitely when
   you have 110 volt power because the battery charger will keep
   the battery supplied with current.  One fan will be located in
   the front roof vent, another in the range. hoods.

   The 12 volt power should be used sparingly and equipment turned
   on only when being used (don't leave lights on in areas where
   no one is present, etc.) when 110 power is not available.

   Charger will charge average battery in approximately 3 to 4
   hours.  When charge is completed, the high charge rate will
   automatically shut off and turn on a trickle charge which will
   remain "on" until charger is disconnected.  Trickle charge may
   ]be left "on" for an indefinite period as long as cells have
   sufficient water in them.  The reset charging rate, remove both
   battery clips and AC plug, then reconnect charger.

   If the trailer is to be stored for several months without being
   hooked up to 110 volt power on e of the charge cables should be
   disconnected from a battery terminal making sure to connect it
   back up when trailer is again used.

		      12 VOLT AIR COMPRESSOR

   If you coach is equipped with an air compressor for the water
   system it will be located in front at one end of the water tank.

   This compressor will keep the pressure in your water supply
   tank between 20 and 40 lbs.  An on-off switch and fuse will be
   located above the water tank at the front of the coach.  You
   may conserve your battery by turning on the compressor with the
   switch and turning off when the compressor has run a few min-
   utes.  Three or four lbs. of pressure is sufficient to circu-
   late the water through your system.

 CONDENSATION IN MOBILE HOMES

 Too much moisture in the air resulting in condensation of water on the windows and
 walls of coaches has been a problem to many mobile home residents.

 This is just the reverse of what happens in the conventional frame house where most
 people equip their furnaces with humidifiers to add moisture to the air.  It is not
 uncommon even in these homes to see water or frost on the windows.

 If you will follow the suggestions listed below, your coach will stay dry and
 comfortable and you will avoid damage to the finish of the interior that so often
 results if the condition is allowed to continue.

 	1.  Do not dry washing or hand wet clothes inside the coach.

 	2.  Use the kitchen vent fan when the range is burning.

 	3.  Open the bathroom vent and keep bathroom closed when using shower.

 	4.  Keep one or more vent windows cracked open.

 	5.  Install storm windows.

 	6.  Keep blower on heater in operation.

 	7.  Inspect and clean blower wheel at least twice each heating season.

 	8.  A thermostat is a worthwhile investment.  It will not only save you
 	   fuel but it will maintain uniform temperature.

 	9.  Open the fresh air damper on the heater by moving handle forward or
 	   as shown on damper nameplate.

 We have often heard mobile home residents complain that moisture is coming through
 the plywood and damaging the interior of the coach.  Actually what happens is that
 moisture in the air of the coach condenses on windows and walls.

 The amount of water that  cubic foot of air will hold depends upon the temperature
 of the air.  The higher the temperature, the more moisture the air will hold.  En-
 gineers have a methods of measuring the moisture content of the air.  When they say
 the relative humidity if60 per cent. they mean that the air is holding 60 pr cent
 of the moisture it could hold at the particular temperature at which it was
 measure.

 Everyone has seen a glass of ice water "sweat" in the summertime.  Actually the
 "sweating" of the class of ice water and the water on the window of your coach
 are caused by the same thing

 The reason for moisture condensation is that the air close to the water glass or 
 window is cooled to what is called the dew point.  When the Dew point is reached,
 the air next to the object has a relative humidity of 100 percent.  Just like
 a dripping sponge saturated with water, the extra moisture in the air condenses 
 on the window.
 
 With an inside room temperature of 70 degrees and an outside temperature of zero,
 the inside surface of a single window will be about 22 degrees,  Under these
 conditions if the relative humidity is more than 15 per cent, moisture will start
 to condense on the glass.
 
 Now when we install storm windows and with the same inside and outside temperatures
 as above the inside surface of the window ill be warmer than it was with single
 glass.  With the warmer glass surface, condensation will not start until the rel-
 ative humidity is about 31 per cent.
 
 We often see people operate the gas range without turning on the vent fan.  The
 vent fan should be used for two reasons.  the boiling of water during cooking
 obviously adds moisture to the air, but many people do not realize that the gas
 flame itself gives off some moisture.
 
 In the average 40 foot mobile home, there are about 2100 cubic feet which would be 
 an average of 700 cubic feet of air per person for three people.  A conventional 
 house with a foundation 24 x 32 feet will give over 2000 cubic feet per person for
 three people.
 
 this smaller amount of air per person together with the tight construction of a 
 coach and its unusually well insulated walls add to the condensation problem.
 
 Know that the amount of moisture in each cubic foot of air in a coach would be
 larger, the coach manufacturer has used tarred paper or aluminum foil in the
 construction of his coach to serve as a barrier o the moisture filled air.  the
 heater manufactures have provided means for bringing in the dry outside air to
 help reduce the moisture content of the air in the coach.
 
 There is a very definite reason for every suggestion made in the list above.  Keep
 in mind that when you encounter a fogged windshield in your automobile, the first
 thing you do is crack open a window.  Follow the nine suggestions religiously and
 take advantage of feature provide by your mobile home manufacturer and its heat-
 ing system for a dry, comfortable coach.
