The suspension foundation is a structure of either wooden frame or reinforced concrete. It
must be firm and reliable to bear the weight of more than 200 kg and capable of bearing
vibration for long periods.
The cassette should be suspended as shown in the below sketch:
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 center of the indoor unit is in alignment with the center of the opening in the ceiling.
Drainage pipe installation
1. The drain pipe should be properly insulated to prevent the generation of
condensation. It should be installed with a downward gradient (1/100-150).
2. The unit has drain pump which will lift up to 700 mm. However after the pump
stops the water still in the pipe will drain back and may overflow the drain tray
causing a water leak.
3. When draining multiple units into a common drain line, this common drain should be
installed about 100mm below each units drain outlet, as shown in the drawing.
