Indoor unit installation
(Note: Below reference is only applicable to a house made of concrete.)
Measure the distance H between the roof surface and the ceiling board ;
Make four suspending poles with M10 screw thread on both ends (metric system)
as the below figure shown.(processed with 10 pole)
H
L1
L1
L
Value of L and L1 are calculated as below
L1=50mm (when H<255mm
L1=40mm
L=1.5L1+H-230 (unit: mm)
Turn 4 attached nuts onto the thread ends on the suspending poles as shown below:
Take out the suspending poles with nut on one end, mount them on the fixed suspending bracket,
then tighten the nuts and washers on the top of the suspending brackets.
Cut an opening (880x880) on the ceiling board with assistance of the moulding board, make sure to
follow the same direction of the holes for roof bolts. Fix the edges of the opening with the
[-shaped aluminum bars.
Mount the attached suspending brackets with expand bolts M8X50 on the roof surface.
Make sure to tighten the expand bolts and nuts well. The opening of suspending brackets
should face outward as shown below.
Take out the moulding board from the packing carton of indoor unit, do not fold it, just use it to
decide an installation location and direction of the unit on the roof and ceiling.
Press the moulding board tightly onto the surface of the roof, draw out the hole position for
expand bolt with a pencil, then take off the moulding board, drill 8 holes for the expand bolts.
It is preferable if the depth of holes just reveal the thread of the poles.
