Installations (refer to Page 4 for parts):
As illustrated in Figure 1A, drill four holes with diam-1. 
eter not exceeding 5/8” and depth of 3” to 3-1/2” on the 
false ceiling. Fasten two hexagonal wood screws  at two 
of these holes opposite from each other, reserve approx-
imately 1/8” for the top support plate as shown in Figure 
1B. Cut out a circle of 7-1/2” diameter for duct work. Use appropriate anchors for your ceiling composition:
Wood ceiling: Use the provided hexagonal wood screw.• 
Sheet rock ceiling: Attach top supporting plate to ceiling joists or stud blockings if possible. If ceiling • 
joists or stud blockings are not available, it is required to build a supporting structure behind the sheet 
rock for best weight support.
Concrete ceiling: Use concrete sleeve anchor.• 
Place  support  frames  inside  the  top  support  plate,  adjust 2. 
support  frames  to  length  required  and  lock  the  support 
frames using sixteen (16) 4mm x 8mm Phillips Head Tap-
