Resetting the high pressure switch

1. Make sure the RG8.0 / RG4.0 is switched off.
2. Check if the recovery tank is overfilled.
3. Close the recovery tank valve(s), the hose shut-off
valve(s) connected to the tank, and the inlet and
outlet control valves of the RG8.0 / RG4.0.
4. Disconnect the hose(s) only from the recovery tank.
Retain the hose connections to the RG8.0 / RG4.0.
5. Connect the hose(s) to another recovery tank which
is empty.
6. Open the recovery tank valve(s).
7. Open the outlet control valve of the RG8.0 / RG4.0.
8. Open the shut-off valve in the hose connected to
the recovery tank liquid port and allow refriger-
ant to flow and pressure on the outlet side of the
RG8.0 / RG4.0 to drop.
9. Once the pressure in the outlet of RG8.0 / RG4.0
drops below 28 bar, switch on the RG8.0 / RG4.0.
10. When the RG8.0 / RG4.0 restarts, slowly open the
inlet control valve of the RG8.0 / RG4.0 and resume
recovery. If in push / pull configuration, it will also
be necessary to open the shut-off valve on the hose
connected to the vapour port of the tank.
i
Once the safety pressure switch is activated, it
will remain open until the pressure within the
RG8.0 / RG4.0 is reduced below 28 bar, at which
time it will automatically reset. It is not possible to
operate the RG8.0 / RG4.0 until this occurs.
