(1) Test run from an outdoor unit.
Whether external inputs are set to ON or OFF, you can start a test run by using the SW5-1 and SW5-2 switches provided on the outdoor unit board.
Please set SW5-2 to ON for a cooling test run (It is set to OFF at the factory for shipment)
Turning SW5-1 from OFF to ON next will cause all connected indoor units to start.
When a test run is completed, please set SW5-1 to OFF.
Note: During a test run, an indoor unit cannot be operated from the remote control unit (to change settings). (“Under centralized control” is indicated)

○
Use the instruction manual that came with the outdoor unit to explain the operation method to the customer.
Please ask the customer to keep this installation manual together with the operation manual of his indoor units.
○
Instruct the customer that the power should not be turned off even if the unit is not to be used for a long time. This will enable operation of the air conditioner any time.
(Since the compressor bottom is warmed by the crank case heater, seasonal compressor trouble can be prevented.)

Low refrigerant quantity
①
Refrigerant quantity is insufficient. Recharge the refrigerant.
< Guideline of recharge>
・
20% of the additional refrigerant quantity for piping* (Upper limit: 5 kg)
Recharge the refrigerant in the liquid state from the check joint of low pressure line.
Make sure to measure the quantity before recharging.

H_L
Couldn’t judge.
It cannot judge (a state that it cannot judge properly).
State of refrigerant might have been unstable during the check operation due to
influence of wind, temperature change, etc.
①
Check the expansion valve of indoor unit (disconnected coil, disconnected connector
