To support the weight of the unit, use barb bolts in the situation with the ceiling. In the situation with the new
ceiling, use inlaid bolts, embedded bolts or other parts provided on site. Before installation, adjust the gap
between the bolts and the ceiling.
■
Use four M10 hoisting studs (provided on site) (when the height of the hoisting stud exceeds 0.9m, M10 studs
should be used.). The gaps should be kept according to the overall drawing of the air conditioner. Make the
installation according to regulations for various building structures as to ensure the safety. Use the level meter to
perform the parallel installation.

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.
(5) Tighten the nut on the washer.
