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.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 (The remote control packed
with the ceiling assembly).
2.
Remove the ceiling grille from the ceiling
assembly.
3.
Before the ceiling assembly can be
mounted to the roof top air conditioner,
the fabric duct collar must be fastened
to the basepan of the roof top air
conditioner with 4 screws by upper duct
plate (see Figure 5-2、Figure 6-1、
Figure 5、Figure 5-1).
4.
Before lifting the ceiling assembly, pull
the fabric duct collar so it hangs out of
the way and does not get caught under
the ceiling assembly frame.

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.
6.
Set the fabric air duct into the duct opening of
installation plate sub-assy and cut off four corner
of fabric air duct. Because the thickness of
vehicle top is different, the distance between the
opening and the installation plate sub-assy is
shown in figure 6.
7.
Fasten each side of the fabric duct with
fitting the bottom duct plate to the ceiling
assembly frame with 4 screws (see Figure
6).Trim any excess fabric that may extend
beyond edge of bottom duct plate.
