EFRIGERANT TRANSFER
a) Operate on the refrigerant's system in order that most part of the refrigerant will be pumped into
the liquid side of the system.
b) By means of the flexible hoses with ball valve, connect the cooling system liquid receiver
connection to the stocking cylinder liquid valve (with tube) (see the above picture)
c) By means of the flexible hose (T1) with ball valve, connect the recovery unit filter drier (IN) to the
stocking cylinder vapour valve (valve without tube)
d) By means of a flexible hose (T2), connect the exit connection (OUT) of the recovery unit to the
A/C system vapour connection
e) Make sure that V1 valve in on position 1 Recovery.
f) Open the INPUT and OUTPUT valves of the recovery unit
g) Open the valves of the flexible hoses T1 and T2 of the recovery unit
h) Open the ball valves of the connecting flexible hoses
i) Open the valves on the manifold
j) Open the stocking cylinder valves
k) Switch the Power Switch to position "ON", then press the START key to start the unit.
Watch the manifold sightglass; the refrigerant transfer from the liquid receiver to the stocking cylinder is
complete when you can see through the sightglass that the liquid refrigerant has stopped flowing.
l) When the refrigerant transfer has been completed, close the cylinder vapour valve (valve without
tube)
m) Close the valve of the T1 hose and wait until you can read a pressure of -0.2 bar on the M1 low
pressure gauge (or wait for the automatic stop of the unit if the BY-PASS switch is on the AUTO
position)
n) Turn the recovery unit off (Power switch to position "OFF")
o) Close the cylinder liquid valve and the flexible hose ball valve connected to it.
p) Close the valve of the T2 flexible hose
q) Close all the manifold and flexible hoses valves used for connections
The recovery of the residual gaseous refrigerant from the inside refrigerant system can be done by
connecting the unit as shown in "4.2 Refrigerant Recovery"
