Troubleshooting

5.1

Basic operational test

i
By performing the basic operational test, you can
validate normal and correct operation of all features.
Refer to the table following this procedure if you
encounter any problems.
1. Ensure that there is no residual refrigerant left in the
RG8.0 / RG4.0. If there is residual refrigerant, refer
to chapter 3.2 for purging residual refrigerant.
2. With nothing connected to the RG8.0 / RG4.0 and
recovery / purge valve (black) in the RECOVER posi-
tion, open the inlet control valve (blue) and outlet
control valve (red) valves.
3. Start the RG8.0 / RG4.0 and close the inlet valve.
 The RG8.0 / RG4.0 should shut-off due to Low
Pressure (LP) cut-out. Upon opening the inlet
valve, the RG8.0 / RG4.0 should restart.
4. Upon closing the outlet valve, the RG8.0 / RG4.0
should begin to pump up pressure on the High Side
(red) gauge.
 When the pressure reaches approximately
38.5 bar, the RG8.0 / RG4.0 should shut off due
to High Pressure (HP) safety switch.
5. Slowly open the outlet valve and the RG8.0 / RG4.0
should restart when pressure drops below 28 bar.
