for Generator requirements. These Generator requirements
come from experience consumers have with our equipment
in field applications. When sizing the Generator, the total
electrical power consumption of the Recreational Vehicle
must
be taken into consideration. Keep in mind that
Generator; lose power because of attitude increases above

LOCATION OF AIRCONDITIONER ON
RECREATIONAL VEHICLE
This Air Conditioner is designed to be installed on the roof of a
RecreationalVehicle. One or more units may be installed on
the vehicle, dependent upon the size and strength of the roof
and the expected cooling requirements of the RV.
A. Normal Location of Air Conditioner(s)
(Refer to FIG. 1)
Normally the Air Conditioner(s) is installed in an existing
roof vent. When the roof vent is removed it normally
creates a
14" x 14'' opening through the roof required
for the installation of the Air Conditioner(s).
This Air Conditioner is Listed by Underwriters Laboratories,
Inc. as complying wilh UL Standard
484.
Other Locations for Air Conditioner(s):
When noroofvent locationisavailableoraroofvent
locationisnottobeused, itis recommendedthatthe
Air Condltioner(s) be installed as follows:
1. For one unit installation: Air Conditioner should
be mounted slightly folward
of center (front to
back)andcenteredfromsidetosideontheRV.
2.
Fortwounltinstallations: InstalloneAirCondi-
tioner l/3 and one Air Conditioner 213 back from
front of RV and centered from side to side.

If the opening exceed s 141/2# 141/2"it will be
necessary to make the opening smaller by instal-
ling spacers or close off plates.
2. If the opening is smaller than 14" x 14" it will
be necessary to enlarge the opening.
3. Route a grounded power supply line from circuit
breaker or fuse box to the roof opening.
a. The power supply must be a separate circuit,
fused with a

x OPERATING INSTRUCTIONS
(Refer to FIG. 6)
A. Controk
1.
Thermostat (Dialon right side when facing air box)
hasatemperaturerangeof 650FinCOOLposi-
tionto 90°F inWARMposition.The thermostat
controls the unit wmpressor ON and OFF cycle in
the cooling mode and the electric heater ON and
OFF cycle in the heating mode.
2
Selector Switch (Dial on left side when facing air
box) controls the unit fan speeds, heating mode,
cooling mode and fan mode of operation.
B. Cooling Operation
1.
Set the thermostat to the position which will
give your &sired comfort level.
2 The selector switch is to be set as follows:
a. HIGH COOL: Selectedwhen maximum
cooling and &humidifying
is required.
b. MED COOL: Selected when medium woling
is required.
c
LOW COOL: Selected when minimum cool-
ing is required. Normallythis position
is
sddedfor night time operation.
The air conditioner wmpressor will come on and
off
as cooling is required to maintain your desired
temperature level as set at the thermostat.
NOTE:
The airconditioner blowerruns continuously
tocirculatetheair and maintainaneventemperature
inthe RV.
lt does not comeonand off withthe com-
pressor.
C. Fan Operation
When you wish to circulate the air inside your RV,
without heatingor cooling,select one ofthethreefan
speeds (HIGH FAN, MED FAN or LOW FAN). The
fan will run continuously and circulate the air in the
RV.
D. Heating Operation: (Wnh Optional Electric Heater
Installed).
NOTE: This electric heater will not replace a furnace
for heating your RV in cold weather. It is intended to
remove the chill from the air on cool days or mornings
only.
1.
Set the thermostat to positionwhich will give your
desired comfort level.
2
The selector switch can be set in any of the three
heating positions, but normally it will be placed in
the LOW HEAT positionfor best results.
The electric heater will turn on and off as heating
is
required to maintain your desired temperature level as
set at thermostat.
NOTE: The air conditioner fan runs continuously to
circulate the air inthe RV.
lt does not come on and
off withthe heater.
E. Operation of air conditioner WITHOUT Optional Electric
Heater installed.
When the optional electric heater is not installed in the
air conditioner and the sdector switch is in one of the
heating positions (HIGH HEAT, MED HEATor LOW
HEAT)theair conditioner works as
if it were inFan
Operation. No damage will be caused to the air condi-
tioner when these positions are used.
-6-

F. Off Position
To shut the air conditioner
OFF place the selector
switch in the
OFF position.
G. Compressor Time Delay Models:
When the 6022xx Series Air Conditionersare turned on
thefanstartsimmediately.When thethermostat calls
forcoding,there
is a 2 minutedelay beforethe com-
pressor starts. This is to reduce the load on the power
supply and prevents short cycling of the compressor.
H. Compressor Non-Time Delay Models:
When the 6003xx Series Air Conditionersare turned on
and the thermostat calls for cooling, the fan and wm-
pressor start at the same time. After shutting the air
wnditioner down manually b y eitherthe sdector switch
orthethermostat, alwayswait at least 2to3 minutes
before turning the air conditioner back on. This allows
the refrigerant pressures in the air conditioner to
equalize so the compressor may restart.
XI MAINTENANCE
AIR FILTERS: Periodically remove the retum air filters
located above the removable panels in the air box. Wash the
filters withsoapandwarm water, let dly andthen reinstall.
Note: Neverrunthe air conditioner without retumairfilters
inplace. This may plug the unit evaporator coil with dirt and
may substantiallyaffect the performance of the unit.
SERVICE-Unit Doer Not Operate
If your unit fails to operate or operates improperly,check the
following before calling your sewice center.
A.
If RV is connected to motor generator,check to be
sure motor generator is running and producing power.
6.
If RV is connected to power supply by a land line.
check to be sure line is sized properly to run air condi-
tioner load and
it is plugged into power supply.
C. Checkyourfuseorcircuit breakertosee if
it is open.
D. Intheairconditioner airbox, check tobesuretheair
conditioner conduit is plugged into the selector switch
box.
E. After the above checks call your local service center for
further help.This unit must
be sewiced by qualified
sewice personnel only.
When calling for service atways g~ethe air wnditioner
