INSTALLATION INSTRUCTIONS
Ceiling Suspending
Situation with New Ceiling:
(1) Install the indoor unit temporarily:
attach the hoisting foot to hoisting stud. Make sure that nuts and washers should be used at two ends of the foot to
secure the foot.
(2) For the size of the ceiling hole, please refer to the schematic drawing at the previous page.
(3) Adjust the unit to the proper installation location.
(4) Check if the unit is in the horizontal level:
The indoor unit is equipped with a built-in drainage pump and a floater switch. Check if the 4 angles of the unit are in
the horizontal level with the water level or the polythene tube with water, as shown in the figure,taking only one indoor
unit as an example. If the unit inclines opposite to the
direction of condensate flow, the floater switch might
have faults, causing water dropping. (When lifting can be
tilted to the drain, the long side of the horizontal height
difference 0 ~ 0.4in (10mm).)
(5) Tighten the nut on the washer.
(6) Remove the mounting cardboard.
Situation with Original Ceiling:
(1) Install the indoor unit temporarily: attach the hoisting
foot to hoisting stud. Make sure that nuts and washers
(provided on site) should be used at two ends of the foot
to secure the foot.
(2) Adjust the height and location of the unit.
(3) Perform Step 4 and 5 in Situation with New Ceiling.
