Safety precautions

All units shall be earthed. The earth must not be connected to a gas pipe, water pipe, or telephone

line. Poor earthing could cause electric shock.

Be sure to install a circuit breaker to avoid electric shock.

Arrange water drainage according to this manual. Cover pipe with insulation materials to prevent

condensation occuring. Improper installation of water drainage will cause water leakage.

WARNING

Installation work must be carried out by professional qualified people, do not install the unit by

yourself. Incorrect installation will cause water leakage, electric shock and potentially fire.

Install the unit as per the manual. Incorrect installation will cause water leakage, electric

shock or fire risk.

Be sure to use specified accessories and parts. Otherwise, water leakage, electric shock, fire risk

or unit falling down may occur .

Mounting position must be strong enough to hold the unit. Or, the unit will potentially fall down

causing injuries.

When installing the unit, take in consideration storms and high winds. Incorrect installation may

cause the unit to fall down.

All electric work should be carried out by experienced personnel as per current regulations and

this manual. Incorrect installation or undersized electric cable may cause electric shock or fire risk.

All circuits must be earthed. Ensure that no external forces will affect the terminal block and electric

cable. Poor wiring and installation may cause fire risk.

Arrange wire connection between connecting the indoor and outdoor power supply correctly. Fix

terminal cover firmly to avoid overheating, electric shock or even fire risk.

In the case of a refrigerant leakage during unit installation, keep the room well ventilated.

Check the unit upon installation. Be sure there is no leakage. Refrigerant will induce a poisonous

gas subject to heat.

Isolate power supply before touching terminal block.
