ADDING REFRIGERANT

The R-410A refrigerant is blended. Add only liquid refrigerant.

Measure the quantity of the refrigerant depending on the length of the liquid side pipe. Add a fixed quantity of the
refrigerant using a scale.


Connect the manifold gauge and purge the manifold gauge.

Open the manifold gauge valve of the liquid side service valve and add the liquid refrigerant.

If you cannot fully recharge the additional refrigerant while the outdoor unit is stopped, use the key on the outdoor
unit.
PCB to recharge the remaining refrigerant.

Adding the cooling refrigerant:
1) Press the function key for adding refrigerant in cooling mode.
2) After 20 minutes of operation, open the valve on the gas side.
3) Open the valve for the low-pressure side on the manifold gauge to recharge the remaining refrigerant.

Adding the heating refrigerant:
1) When recharging the heating refrigerant, connect the low-pressure pipe from the manifold gauge to the suction
charging port.
2) Press the function key for adding refrigerant in heating mode.
3) After 20 minutes of operation, open the valve on the suction charge port.
4) Open the valve for the low-pressure side on the manifold gauge to recharge the remaining refrigerant.
Open the gas side and liquid side service valves completely after charging the refrigerant. (If you operate the Air
to Water Heat Pump with the service valve closed, the important parts may be damaged.)
