Installation Procedures
3. Ceiling Hole & Reinforcement
(1) Cut and withdraw the foundation of ceiling according to the size of indoor unit.
(2) After cutting an appropriate hole, reinforce the cutting area on the foundation of indoor unit,
and append the rim to the ceiling to secure its foundation. In order to prevent the ceiling
from vibrating, it is vital to reinforce the ceiling foundation and ensure the original levelness
of the ceiling.
4. Hoisting Stud Installation
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
proceeding the 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.
<After finishing the installation of the ceiling>
(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.
