To refer to the above installation dimension to ensure the performance of units as much as possible.
The supports shall carry weight 4 times larger than the indoor units to avoid unnecessary vibration and
reduce the noise.
Installation Instruction
a. To keep indoor units from the source of heat and vapor.
b. To measure the position of fixing and drill hole in the ceiling and fix the units tightly.
c. The paper temperate shall be measure dimension before usage.
d. Ensure the paper temperate is the same dimension as hole dimension in the ceiling.
e. Before the completion of ceiling decoration, leave the paper temperate with the indoor unit.
f. Ensure the distance between the hang pole is 620.4mm×790.0mm.
g. To ensure use screw to fix the indoor units tightly.
h. To adjust distance between the bottom panel and ceiling is less than 35.0mm.
