CONNECTING 115VAC WIRING
1. WARNING - SHOCK HAZARD: To prevent the possibility of severe personal injury or equipment damage due to
electrical shock, always be sure the electrical power is disconnected or off before beginning installation.
2. Route the 115 VAC supply wiring previously routed into the frame of the roof opening, through the strain relief of
the electrical box and into the high voltage wiring area.
DANGER
TO PREVENT THE POSSIBILITY OF SHOCK INJURY FROM APPLIANCE OPERATION: THE WHITE
WIRE MUST BE CONNECTED TO NEUTRAL IN THE SERVICE BOX ENTRANCE AND THE GREEN
GROUND WIRE MUST BE CONNECTED TO A GROUNDING SCREW.
ATTACH CEILING GRILL
1. Position the grill next to the interior frame and attach it with the 4 provided screws.
2. Install the filter on the air intake grill section.
3. Snap the intake grill section onto the main grille.
MAINTENANCE
1. AIR FILTER:
Remove the return air filter (after every 30 days of use) located above the removable air intake grill. Wash the
filter with soap and warm water, let dry and then reinstall.
Note: Never run the air conditioner / heat pump without putting the air filter back in place. This may plug the
indoor coil with dirt and may substantially affect the performance of the unit.
2. Air Return Grill:
Clean panel and control panel with a soft cloth dampened with a mild detergent. Never use furniture polish or
harsh chemicals.
3. FAN MOTOR:
Factory lubricated and requires no service.
4. FROST FORMATION ON COOLING COIL:
Under certain conditions, frost may form on the indoor coil. If this should occur, inspect the filter and clean if dirty.
Make sure air louvers are not obstructed. Air conditioners / heat pumps have a greater tendency to frost when the
outside temperature is relatively low. This may be prevented by adjusting the thermostat control to a warmer
setting.
SERVICE
If the unit does not operate:
1. If RV is connected to a generator, check to be sure generator is running and producing the proper power.
2. If RV is connected to shore power, check to be sure supply breaker is sized properly to run air conditioner / heat
pump load and it is plugged into power supply.
3. Check your fuse or circuit breaker to see if it is off.
4. After the above checks, call your local service center for further help. This unit must be serviced by qualified
service personnel only.
