Warning:
Do not use the air conditioner if the insulation resistance is less than 1.0M.
• After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage,
looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply.
• To avoid damage to the compressor, make certain that all three phases of the power supply voltage are in the
proper phase sequence.
• If connected in the reverse phase sequence, the indoor unit will not be able to provide sufficient cooling air. The fan
on the outdoor unit that is connected in the reverse phase sequence will tarn in the wrong direction
and makes the compressor rattle.
• If the outdoor unit is connected to the power supply voltage in the wrong phase sequence, P8 error occurs, or
the built-in thermostat triggers the compressor to stop and results in P8 error. Once the built-in thermostat is
triggered, it will take a long time until it returns to its pre-set temperature. Until then, the compressor cannot be
started, even after the phase sequence is corrected.
• Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is
at least 1.0M.
• Do not carry out this test on the control wiring (low voltage circuit) terminals.
Power is not supplied to the remote
