Gas Leak Test

• Use a leak detector manufactured specially for the HFC refrigerant (R32, R410A,
R134a, etc.) when testing R32 or R410A.
The sensitivity of leak detectors for previous HCFC refrigerants (such as R22) lowers to
about 1/40 when used with HFC refrigerants and these detectors cannot be used.

WIRING

1. Using the specified cables, ensure to connect the wires, and fix wires securely so
that the external tension to the cables do not affect the connecting part of the
terminals.
Incomplete connection or fixation may cause a fire, etc.
Be certain to install wires by connecting them to terminals of the same numbers
according to the following wiring diagram.
2. Be sure to connect earth wire. (Grounding work)
Do not connect the earth wire to gas pipe, city water pipe, lightning rod, or the earth wire
of telephone.
Incomplete earth causes an electrical shock.
3. For electric work, strictly follow the Local Regulation in each country, Indoor,
outdoor, and this Installation Manual, and use an exclusive circuit.
Capacity shortage of power circuit or incomplete installation may cause an electrical
shock or a fire.
Indoor unit And Outdoor unit Connection Wiring
1. Install wires from the outdoor unit to the header unit as in usual wiring.
(Wires (1), (2), (3) and earth wire.)
2. Install wires (1), (2) and earth wire only when installing connection wires from the header
unit to the follower unit.
Remote Controller wiring
1. Installing connection shield wires (MVVS 0.5 to 2.0 mm
follower unit to conform to EMC standard.
2. Install shield wires between the header unit and follower unit. The shield wires of the
remote controller have no polarities.
The remote controller circuits are low voltage circuits. These circuits must not be made
to directly contact indoor unit and outdoor unit connecting wires or contained in the same
conduit tubes that house indoor unit and outdoor unit connecting wires.
(Otherwise malfunction will be caused by noise)
