Test Operation & Troubleshooting & Maintenance
Safety Valve
It is used to prevent the pressure of circulation water from
increasing unusually. When the pressure is larger than the set
point (0.6MPa), this valve will open to relieve water pressure.
Exhaust Valve
It is used to expel air trapped inside the water system to make
sure normal operation of the system. It is usually installed at the
highest point of the system.
5.3.2 Charging and Discharging of Refrigerant
The unit has been charged with refrigerant before delivery. Overcharging or undercharging will cause
the compressor to run improperly or be damaged. When refrigerant is required to be charged or
discharged for installation, maintenance and other reasons, please follow steps below and nominal
charged volume on the nameplate.
Discharging: remove metal sheets of the outer casing, connect a hose to the charging valve and then
discharge refrigerant:
Note:
(a) Discharge is allowed unless the unit has been stopped. (Cut off the power and repower it 1
minutes later)
(b) Protective measures should be taken during discharging to avoid frost bites.
(c) When discharging is finished, if vacuuming cannot be done immediately, remove the hose to
avoid air or foreign matters entering the unit.
(d) Vacuuming: when discharging is finished, use hoses to connect the charging valve, manometer
and vacuum pump to vacuum the unit.
