Circuit Seal Test
1. Heat the box up to +20ºC/+70ºF using a ventilated radiator.
2. Connect the gauge manifold to the suction
1
and discharge
2
intakes
of the condenser unit.
3. Connect the central line of the gauge manifold to the vacuum pump.
Use recommended vacuum equipment . Before each use, check that
there are no leaks in the vacuum equipment, either in the pump itself or
in the hoses.
4. Open the gauge manifold and vacuum pump valves. Open all the
solenoid valves on the circuit.
5. Start the vacuum pump and maintain suction until it reaches
500 microns .
6. Once it reaches 500 microns, leave suction running for one hour .
7. Close the vacuum pump valve, switch off the pump, checking that the
gauge reading for the vacuum pump does not exceed 2000 microns in
the following 5 minutes. If it does exceed 2000 microns, follow the
procedure in the section:
“In Case of Leaks” .
8. Start the vacuum pump again and open the vacuum valve. Leave the
pump running until it reaches 500 microns of pressure again.
9. Once it reaches 500 microns, close the vacuum pump valve and switch
off the pump. The unit is ready to be filled with refrigerant.
