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 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.
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.
Preparation of Decorated Board
■
Don't put the decorated board downward to the floor. Putting it against the wall or on the extrusive objects is not
allowed.
■
Don't touch the wind deflector or apply force on it, or the wind deflector will have faults.
(1) Check if the indoor unit is in the horizontal level with the water level and the polythene tube with water and
check if the size of the ceiling hole is correct. Take away the water level before mounting the decorated board.
(2) Fasten the screw to make the height difference between two sides of the indoor unit less than 5mm.
