Maintenance
7. Slightly open the liquid valve and let some refrigerant go to the connection pipe to balance the pressure
inside and outside of the connection pipe, so that air will not come into the connection pipe when
removing the hose. Notice that the gas and liquid valve can be opened fully only after the manifold valve
assembly is removed.
8. Replace back the caps of the liquid valve, gas valve and also the service ports.
NOTICE:
• For large-size units, there are maintenance ports for liquid valve and gas valve.
During evacuation, you may connect the two hoses of the manifold gauges to the
maintenance ports to speed up the evacuation.
• Refrigerant should be reclaimed into the appropriate storage tank. System should
use oxygen-free nitrogen purging to ensure safety. This process may need to repeat
several times. Do not use compressed air or oxygen in this process.
Refrigerant Charging
Pre-Charging
1. Connect the high pressure gauge line to the liquid
service valve and connect the low pressure gauge line
to the vapor line valve. Connect the middle gauge
line to the vacuum pump. Power on the vacuum
pump and evacuate the system.
2. After evacuation, close the high and low pressure
gauge valves and remove the middle gauge line from
the connector of vacuum pump and connect the
refrigerant tank.
3. Loosen the middle gauge line from the connector
and slightly open the refrigerant tank valve. Purge the
middle gauge line. Tighten up the connector again
and completely open the valve of refrigerant tank at
the same time.
4. Keep the refrigerant tank erect and put it on an electronic scale. Zero the scale.
