Precautions

For ensuring throttled efficiency, please

mount the throttle as horizontally as

possible.

Wrap the supplied anti-shock rubber at

external of the throttle for denoise.

BEFORE PERFORMING ANY
ELECTRICAL WORK, READ THESE
REGULATIONS

1. All wiring must comply with local and national

electrical codes, regulations and must be

installed by a licensed electrician.

2. All electrical connections must be made

according to the Electrical Connection Diagram

located on the panels of the indoor and outdoor

units.

3. If there is a serious safety issue with the power

supply, stop work immediately. Explain your

reasoning to the client, and refuse to install the

unit until the safety issue is properly resolved.

4. Power voltage should be within 90-110% of

rated voltage. Insufficient power supply can

cause malfunction, electrical shock, or fire.

5. If connecting power to fixed wiring, a

surgeprotector and main power switch should

be installed.

6. If connecting power to fixed wiring, a switch

or circuit breaker that disconnects all poles and

has a contact separation of at least 1/8in (3mm)

must be incorporated in the fixed wiring. The

qualified technician must use an approved

circuit breaker or switch.

7. Only connect the unit to an individual branch

circuit outlet. Do not connect another

appliance to that outlet.

8. Make sure to properly ground the air conditioner.

9. Every wire must be firmly connected. Loose

wiring can cause the terminal to overheat,

resulting in product malfunction and possible fire.

Do not let wires touch or rest against refrigerant

tubing, the compressor, or any moving parts

within the unit.

If the unit has an auxiliary electric heater, it must

be installed at least 1 meter (40in) away from

any combustible materials.

To avoid getting an electric shock, never touch

the electrical components soon after the power

supply has been turned off. After turning off

the power, always wait 10 minutes or more

before you touch the electrical components.
