Heat insulation for pipe
Apply heat insulation of pipe separately at the liquid, gas, and balance sides.
Be sure to use thermal insulator resistant up to 248°F (120°C) or higher for pipes at the gas side.
Finishing after connecting pipes
After piping connection work has been finished, cover the opening of the piping/wiring panel with the piping
cover, or fill silicon or putty into the space between the pipes.
In case of drawing-out the pipes downward, also close the openings of the base plate.
Under the opened condition, a problem may be caused due to the entering of water or dust.

WARNING
The equipment shall be installed in compliance with NEC and local codes.
CAUTION
Do not connect high voltage power wires to the control terminal blocks (Uv (U1, U2), Uh (U3, U4), Uc (U5, U6));
All fi eld wiring insulation rating must comply with NEC and local codes.
All wiring must be strained relieved as specifi ed by NEC and local codes.
Refrigerant piping and control wiring should use the same routing.
Do not energize the indoor units until leak check and vacuuming are completed.
For indoor unit power and control wiring see indoor unit installation instructions.
NOTE
Use copper supply wires only.
Use wiring with insulation rated for the highest voltage involved for communication and power wiring.
