Gas Leakage Check

WARNING: Do not mix any substance other than the specified refrigerant (R32) into the refrigeration cycle.

When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.

R32, as well as other refrigerants, should always be recovered and never be released directly into the environment.

Use a vacuum pump for R32 or R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit.

Use tools for R32 or R410A (such as the gauge manifold, charging hose, or vacuum pump adapter).

When piping work is completed, it is necessary to evacuate the air and check for gas leakage.

If using additional refrigerant, perform air evacuating from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant.

Use a hexagonal wrench (4mm) to operate the stop valve rod.

All refrigerant pipe joints should be tightened with a torque wrench at the specified tightening torque.

Outdoor Unit For Split System Test

Measure the supply voltage

Supply voltage falls in the specified range

Select operation mode

In cooling mode, select the lowest programmable temperature; in heating mode, select the highest programmable temperature.

Trial operation may be disabled in either mode depending on the room temperature.

After trial operation is complete, set the temperature to a normal level (26°C to 28°C in cooling mode, 20°C to 24°C in heating mode).

For protection, the system disables restart operation for 3 minutes after it is turned off.

All functions and parts, such as louver movement, are working properly

The air conditioner requires a small amount of power in its standby mode. If the system is not to be used for some time after installation, shut off the circuit breaker to eliminate unnecessary power consumption.
