Adding refrigerant
The Heat Pump unit is provided to users with basic amounts of refrigerants as initial setting values.
While using the unit or doing refrigerant piping works, there can be some loss of refrigerants compared to initial amounts.
To run the units properly, keep the amount of refrigerant which SAMSUNG designated.
Procedures as below is describing how to adding the amount of refrigerant.
1. Connect the manifold gauge and purge the manifold gauge.
2. Open the manifold gauge valve of the liquid side service valve and add the liquid refrigerant.
3. If you cannot fully recharge the additional refrigerant while the outdoor unit is stopped,
use the key on PCB in the Heat Pump to run for recharging the remaining refrigerant.
Adding refrigerants in running condition
1) Press the function key for adding refrigerant.
2) After 30 minutes of operation, open the service valve on low pressure side in Heat Pump.
3) Open the valve for low pressure side in the manifold gauge to recharge the remaining refrigerant.
4) After completing, close the valves in manifold gauge and eliminate the hoses from service valves.
