This is as shown in the drawing as follows:
◇
Adjust the relative position of the suspension hook on the suspension bolt so that the unit can be in
level position in all directions. Check with a level gauge after installation to ensure that the indoor unit
is horizontal, otherwise it will cause water leakage, air leakage etc.
◇
Tighten the bolt and ensure that four hooks are in close contact with the nuts and washers, to fix the
indoor unit under the ceiling.
◇
After the unit is installed ensure it is secure and does not shake or sway.
◇
Ensure that the centre of the indoor unit is in alignment with the centre of the opening in the ceiling.
6.6 Drainage pipe installation
◇
The drainage pipe should be properly insulated to prevent the generation of condensation. Heat
insulation material: the thickness of rubber insulation pipe should be more than 8mm
◇
Drainage pipe must have a downward gradient (1 / 50 1 / 100) to avoid water backflow or leakage etc.
◇
The unit has a drain pump which will lift up to 1200mm. However after the pump stops the water left in
the pipe will drain back and may overflow the drain tray causing water leakage. For this reason please
install the drain pipe as shown.
