• Before installation, please check whether the unit is assembled with three pieces of rubber pads and square sealing
strip.
STEP 1-SELECTING AN INSTALLATION LOCATION & INSTALLING THE ROOF TOP AIR
CONDITIONER
Your air conditioner has been designed for use in recreational vehicles. Check the roof of the vehicle to determine
if it can support both the roof top unit and the ceiling assembly without additional support. Make sure the interior
ceiling mounting area will not interfere with existing structures. Once the location for your air conditioner has been
determined. A reinforced and framed roof hole opening must be cut (if there is no hole) or you may use existing vent
holes.
CASE A.
If a roof vent is already present in the desired mounting location for the air conditioner, the following steps must be
performed:
1. Remove all screws which secure the roof vent to the vehicle. Remove the vent and any additional trim. Carefully
remove all chalking from around the opening so the surface is clear.
2. It may be necessary to seal some of the old roof vent mounting screw holes which may fall outside of the air
conditioner basepan gasket.
3. Examine the roof opening size, if the opening is small than 356x356mm, the opening must be enlarged. If the
opening exceeds 356x356mm, a mounting plate (frame) must be fabricated to reduce the opening size (See
Figure 1).
• Moving parts may cause personal injury. Be careful when test the unit. Do not operate the unit with exterior
cover removed.
WARNING
1. It must be capable of supporting both the weight of
the roof top air conditioner and the interior ceiling
assembly.
2. It must be capable of holding the roof outer surface
and interior ceiling apart and supporting them, so
that when the roof top air conditioner and ceiling
assembly are bolted together,no collapsing occurs.
A typical support frame is shown in Figure 1.
3. There must be an opening through the frame for the
power supply wiring.Route the supply wiring through
the frame at the same time the support frame is
being installed.
CASE B.
Als er geen opening voor een dakventilatie aanwezig is, moet een nieuwe opening in het dak van het voertuig worden
uitgesneden. Er moet ook een bijpassende opening in het plafond binnen in het voertuig worden uitgesneden. Wees
voorzichtig, want het dakstuk kan vast komen te zitten als het dak uit meerdere lagen bestaat. Nadat de opening in het
dak en het plafond binnenin de juiste afmetingen hebben, moet een ondersteuning worden aangebracht tussen het
buitendak en het plafond binnen. Het versterkte raamwerk moet voldoen aan de volgende richtlijnen:
CAUTION
1. The roof top air conditioner must be mounted on a level plane from front to rear and side to side when the
vehicle is parked on a level plane. Figure 2 shows maximum allowable degrees that the unit can be mounted
above or below level.
2. If the roof of the vehicle is sloped (not level) such that the roof top air conditioner cannot be mounted within the
maximum allowable degree specifications, an exterior leveling shim will need to be added to make the unit level.
A typical leveling shim is shown in Figure 3.
3. Once the roof top air conditioner has been leveled, some additional shimming may be required above the
interior ceiling assembly. The roof top air conditioner and the interior ceiling assembly must be square with
each other before they are secured together.
4. After the mounting hole area is properly prepared, remove the carton and shipping pads from around the roof
top air conditioner. Carefully lift the unit on top of the vehicle. Do not use the outer plastic shroud for lifting.
Place the roof top air conditioner over the prepared mounting hole.
