k) Turn the OUTPUT valve to position "OPEN"
l) Slowly open the INPUT valve.
m) In the presence of liquid refrigerant, place the INPUT valve so that it does not go beyond
the "liquid" zone
n) If the compressor starts to knock, slowly throttle back the INPUT valve until the knocking
stops.
o) If the unit fails to start or has stopped due to an excessive quantity of liquid inside the
compressor, please turn the INPUT valve to position "CLOSE", and then start the unit by
pressing the START key; then slowly open the INPUT valve.
p) If you want the unit to stop automatically at the end of the cycle, turn the BY-PASS
switch to position "AUTO".
q) When finishing the liquid refrigerant recovery, completely open the INPUT valve and the
vapour and liquid ports of the manifold; this can improve the liquid recovery speed.
r) Run until desired vacuum is achieved or until the unit stops automatically (the BY-PASS
switch is on the "AUTO" position).
s) Close the vapour and liquid ports of the manifold.
t) Turn the INPUT and OUTPUT valves to position "CLOSE"
u) 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.
