test, repair oradjust vehicle refrigeration
equipment. Even something as "simple" as
tightening a belt can put the uniformed individual at
serious personal risk.
PersonalProtectiveGear
When workingon and
aroundtransport
refrigeration units, it's
important to wear
protective clothing. It's
important toprotect
yourself from battery acid,
hot coolant, refrigerants, refrigerant oils, flying dirt.
debris, and noise.
High Voltage
When working on all-electric units
you may beexposed to high
voltage. To work
safely on this
equipment, you MUST fully
understand and follow safe
electrical
work practices.
Toxic Gas
Frostbite
Liquid refrigerant in contact with your skin will
cause severe injury. Always wear eyeprotection
and protective clothing and use extremecare when
opening valves and removingcaps,gauges,
refrigerant lines,etc.
May Start Automatically
All-Electric units
have an
auto-start
feature that
may
start thesystem
without warning.
Keep all service doors
closed and
guardsin
placewhen
not
working on the
unit. Placethe unit

the
OFFposition and disconnect the negative
battery
cablebeforeworkingonornear
componentsthat
rotate during normal operation.
Refrigerants in the
presence of an open flame
produce toxic gases.
These gases are severe
respiratory irritants
capable of causing death.
Usecaution when working
with refrigerant in aclosed
orconfined area with a limited air supply such as a
trailer, container or hold of a ship. Refrigerant
displaces air and can cause death due to suffocation.
HotSurfaces
Ventilation
Thecompressordischarge
manifold, engineexhaust
system, and otherunit
componentsmay be extremely
hot. These surfaces can cause
severe bums.

Cool Mode Operation
1. Select “COOL”mode to turn on air conditioning.
2. Set desired temperature on control panel.
3. Select desired blower speed with slide bar on control panel.
4. Auto mode when selected will select a fan speed depending upon the difference between the set temperature
and ambient room temperature. Will control the temperature within ± 2°of set point.
Maintenance
Return Air Filter Cleaning (FIGURE #1):
1. Turn system off.
2. Turn knobs counter-clockwise ¼ of turn to remove intake grill and filter.
3. Remove dirt and dust from filter with vacuum and wash filter with soap and water. Filter should be
cleaned once a month during normal conditions and daily or weekly if conditions are warranted.
Note: Never run the air conditioner without the return air filter. Running the air conditioner without a
filter may allow the evaporator coil to be plugged with dirt which will affect the performance of the air
conditioner.
Condenser Coil Cleaning: It is recommended that you clean the condenser and fins every year with
soapy or non-acid coil cleaning liquid in normal conditions or more frequently in extreme conditions to
maintain the efficiency of your RV air conditioner. Eventually, if not cleaned properly the condenser fins
may become clogged with dirt and dust. Do not use high pressure water or steam to clean condenser
fins.
