pressure inside the system is above 38.5 bar, compressor will
automatically shut off.To restart the compressor, please decrease
the internal pressure (High pressure shut-off switch reset
automatically).
When High Pressure Protection is initiated, please find out the
cause and deal with it before restarting the unit.
Cause of High Pressure Protection and Trouble Shooting:
①The input valve of the refrigerant tank is closed-—open the valve
will help solve the problem.
②The connecting hose between the recovery unit and refrigerant
tank is stuck
—
close all the valves and replace the connecting hose.
③The temperature of the refrigerant tank is too high, pressure is too
high—give it some time to cool down and the pressure will come
back to normal.
7. In order to gain maximum recover speed, a hose with inner
diameter bigger than 4mm is recommended and the hose should
better be shorter than 1.5m.
8. While recovering large amounts of liquid, use the Push/Pull Mode.
(see Push/Pull mode operation on Pagell)
9. After recovering, make sure there is no refrigerant left in the unit.
Read the Purge Operation carefully. Liquid refrigerant remained in
the unit may be expanded and destroy the components.
10. If the unit is to be stored or not used for any length of time, we
recommend that it be completely evacuated of any residual
refrigerant and purged with dry nitrogen.
11. Connection hose with check valve is recommended, it can
prevent refrigerant lose.
12. The intake port is equipped with filter screen, please wash it
frequently to keep it clean.
13. The One Key Operation switch is not allowed between the
positions (“0" , "1" , "2" , “3" ) , it must point directly to the numbers.
