STEP 3-INSTALLING THE CEILING ASSEMBLY
Make sure that you have properly matched the roof top air conditioner and interior ceiling 
assembly.Caution before tightening bolts: 
1.The applicable thickness of vehicle roof ranges from 30mm~80mm.
2.
3.When screwing bolts, you can use automatic tool. Do not tighten one bolt completely and then
4.The max torque for tightening ranges from 2.3Nm~2.5Nm.
Before tightening bolts, screw in the four bolts manually and prohibit screwing forcibly.
tighten other bolts, in order to prevent sticking of screw thread.
The following step by step instructions must be performed in the following sequence to ensure proper

Carefully take the ceiling assembly out of
the carton (The remote control packed with
the ceiling assembly).
Remove the ceiling grille from the ceiling
assembly.
Before installing the outdoor unit of recre-
ational vehicle air conditioner on the
vehicle’s top, preinstall the plate of air vent
and foam (upper) on the chassis of the
outdoor unit with 4pc of screws (25mm long)
(See fig.5-1) .
Then carry the outdoor unit to the vehicle’s
top and align with the openings on the
vehicle’s top. Use 2 sets of mounting plate
assembly and 4 screw bolts to mount the
outdoor unit (See fig. 5).
You must start (thread) themounting bolts 
by hand to avoid cross-threading. DO NOT 
START THE MOUNTING BOLTS WITH 
AN AIR GUN. The mounting bolts should 
be tightened, process is completed when 
the basepan gasket has been evenly
compressed.
Before installing the air duct assembly of 
the indoor unit of recreational vehicle air 
conditioner, assemble the foam assembly 
according to the thickness of the vehicle’s 
top. After simulated installation, use an 
appropriate amount of sponge and foam 
assembly. Stick the sponge and foam 
assembly with double faced adhesive 
tape (prepared by user) (See fig.5-2, 5-3).
Install the foam assembly on the air duct 
assembly. Use 4 screw bolts to fix the air 
duct assembly onto the mounting plate. 
After connecting the outdoor unit with 
indoor unit, check whether the foam 
assembly has come loose (See fig.5).
