2.3.3 Detailed Explanation of Setting Mode 2
In case where it is impossible to refill refrigerant when the compressor is stopped, additional
refrigerant charge operation is performed.
[Work procedure]
1. First, conduct normal charging.
2. Turn ON the power of the indoor and outdoor units and fully open the gas side stop valve.
3. Set the indoor unit to "fan operation".
4. Perform "Additional refrigerant charge operation".
Operation procedure
Push and hold the MODE (BS1) button in the Setting mode 1 for 5
seconds or more and set to the Setting mode 2.
Push the SET (BS2) button to set the LED display to "Additional
refrigerant charge operation".
Push the RETURN (BS3) button. (Present settings are displayed.)
Push the SET (BS2) button to set the LED display (as shown in the table
on the right).
Push the RETURN (BS3) button to end setting.
Push the RETURN (BS3) button again to start operation.
Low pressure level (Pe) is displayed
during operation.
Upon the completion of operation (Operation comes to an end after 30
minutes.)
(The display of pressure level immediately before stop blinks.)
Push the MODE (BS1) button once to end the operation.
5. When a prescribed amount of refrigerant is charged, operation ends. If charging is not
6. Remove the refrigerant charge hose and then fully open the liquid side stop valve.
Field Setting
Additional refrigerant charge operation
Charge refrigerant from the stop valve service port on the liquid side while the outdoor unit is

(The stop valves on the liquid and gas sides should be kept closed completely.)
∗ Only when the whole amount of refrigerant cannot be charged while the outdoor unit is surely
stopped, perform the following operation. (Otherwise, it will cause a problem.)
(Be sure to completely close the liquid side stop valve.)
