Indoor unit installation - hanging bolts

Installing Ø10 hanging bolts (four bolts)
Check the ceiling type and isolate roof mountings from possible vibration.
When choosing where to locate the unit, consider the position of the refrigerant pipe and drains
(confirming a minimum drain fall of 1:50). Make sure that the refrigerant pipe, drain pipes, indoor,
and outdoor wiring can be routed and positioned adequately before hanging the unit. Once the unit
is installed, fit off the refrigerant and connections.
Installation of the hanging screw bolts
• Strengthen roof beams as required to support full operating weight of the unit
• Securely mount the hanging screw bolts, and inspect for tightness.
Wood
The mounting holes for the upper insulation panel are used for auxiliary positioning bolts. Put a
mounting bracket transversely over the roof beams, and then install the hanging bolts.
