Procedure for Additional Refrigerant Charge and Check operation
- REYQ18~48P7Y1B (REMQ8~16P7Y1B)
Adding refrigerant using the automatic refrigerant charging function is recommended.
Follow the procedures below.
When charging a system, charging over the permissible quantity can cause liquid hammer.
Always use protective gloves and protect your eyes when charging refrigerant.
When the refrigerant charging procedure is done or when pausing, close the valve of the
refrigerant tank immediately.
- The refrigerant charge port has a electric expansion valve and will be closed at the end of
the refrigerant charging. However, the valve will be opened when operating the unit after
refrigerant charging.
- If the tank is left with the valve open, the amount of refrigerant which is properly charged
may get off point. More refrigerant may be charged by any remaining pressure after the
unit has stopped.
Electric shock warning
Close the electric component box lid before turning on the main power.
Perform the settings on the circuit board (A1P) of the outdoor unit and check the LED display
after the power is on via the service lid which is in the lid of the electric component box.
Operate switches with an insulated stick (such as a ball-point pen)
to avoid touching the life parts.
Make sure to re-attach the inspection cover into the switch box cover
after the job is finished.
If the power of some units is turned off, the charging procedure can not be finished properly.
Make sure to turn ON the power 6 hours before starting the operation. This is necessary to
warm the crankcase by the electric heater.
If operation is performed within 12 minutes after the indoor units, BS units and outdoor unit
are turned on, the H2P-LED will be lit and the compressor will not operate.
Note:
See "Stop valve operation procedure" on page 163 for details on how to handle stop valves.
The refrigerant charging port is connected to the piping inside the unit.
The unit’s internal piping is already factory charged with refrigerant, so be careful when
connecting the charge hose.
After adding the refrigerant, do not forget to close the lid of the refrigerant charging port.
The tightening torque for the lid is 11.5 to 13.9 N · m.
In order to ensure uniform refrigerant distribution, it may take the compressor ±10 minutes to
start up after the unit has started operation. This is not a malfunction.
