In case you perform recovery/recycling cycles of high quantities of liquid refrigerant (more than 2kg),
regulate the input flow by turning the INPUT valve so that the pressure read on the M1 pressure gauge
b) Turn the V1 valve to position Recovery/Recycling
c) Turn the INPUT valve to position "CLOSE". Make sure that the valve Recover/Purge is
on the RECOVER position.
d) Connect the valve of the T2 hose (delivery) to the stocking cylinder
e) Open the valves on the manifold (not supplied with the recovery unit)
f) Open the valve on the stocking cylinder
g) Open the T1 and T2 flexible hoses valves (flexible hoses are not supplied with the unit)
h) Turn the Power Switch to position "ON"
i) Turn the BY-PASS switch to position MANUAL
j) Turn the OUPUT valve to position "OPEN"
k) Slowly turn the INPUT valve to position "OPEN".
l) Press the START key to start the unit
m) In case you perform recovery/recycling cycles of high quantities of liquid refrigerant
(more than 2kg), regulate the input flow by turning the INPUT valve so that the pressure
read on the M1 pressure gauge does not exceed 6 bar
n) If the unit fails to start, turn the INPUT valve to position "CLOSE", restart the unit by
pressing the START key and slowly open the INPUT valve.
o) Let the unit run until you reach a pressure of 2 bar on the M1 gauge. Stop the unit by
means of the Power switch
p) Connect the oil drain hose to the V3 valve situated on the rear of the unit.
q) Slowly open the valve until all the oil inside the unit is drained. At the end of this
operation, turn the V3 valve to close it.
r) Re-start the Recovery/Recycling function by pressing the START key.
s) Run until desired vacuum is achieved or until the unit stops automatically (the "BY-PASS
switch" is on the "AUTO" position").
t) Close the vapour and liquid ports of the manifold.
u) Turn the INPUT and OUTPUT valves to position "CLOSE"
v) Turn the recovery unit off.
Always purge the unit after each use. Failure to purge the remained refrigerant from the unit could result
in the acidic degradation of internal components and ultimately cause premature failure of the unit.
