Step 4 · Installing The Ceiling Assembly - Dreiha Atmos 2.6 Manual

STEP 4 · 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. Before tightening bolts, screw in the four bolts manually and prohibit screwing forcibly.
3. When screwing bolts, you can use automatic tool. Do not tighten one bolt completely and then tighten other
bolts, in order to prevent sticking of screw thread.
4. The max torque for tightening ranges from 2.3Nm~2.5Nm.
The following step by step instructions must be performed in the following sequence to ensure proper installation.
1. Carefully take the ceiling assembly out of
the carton.
2. Remove the ceiling grille from the ceiling assembly.
3. 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. As for installing the
mounting plate sub-assy, these 4 long bolts' holes
should be align with the 4 holes on the a daptor
respectively at first and then the upper planes on the
bottom edge of two
overlapped with the bottom surface of vehicle roof.
(See Figure 5).
4. You must start (thread) the mounting 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.

5. 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 Figure 5-
1, Figure 5-2).
6. 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 Figure 5).
