Checking the cooling system operating pressures
•
Make sure that all the valves on the manifold are closed.
•
Connect the T1 flexible hose to the cooling system low pressure side and open the V1 valve.
•
Connect the T2 flexible hose to the cooling system high pressure side and open the V2 valve (if the
system has got a high pressure connection).
•
Start the cooling system compressor.
•
Read the pressure and the corresponding evaporation temperature on the blue pressure gauge.
•
Read the pressure and the corresponding condensation temperature on the red pressure gauge.
•
Compare these values with those suggested by the cooling system manufacturer.
Disconnecting the vacuum and charing system from the cooling system
After having checked that there are no leaks in the cooling system and that it is functioning well, you can
disconnect the vacuum and charging system from the cooling system. In case the vacuum and charging
operations were performed only from the low pressure side, close the LOW valve on the manifold and the
V1 valve on the T1 hose and disconnect the hose from the system.
In case the vacuum and charging operations were performed from both sides (low and high pressure),
follow the following instructions:
•
with the cooling system on, close the V2 valve on the T2 hose.
•
open the LOW and HIGH valves on the manifold: the liquid refrigerant inside the T1 and T2 hoses will
thus be sucked into the low pressure side of the cooling system.
•
close the LOW and HIGH valves on the manifold and the V1 valve on the T1 hose.
•
disconnect the hoses from the cooling system.
