7.4.9 Oil-level monitor
The oil-level monitor (see Figure 12, item 7) fits in place of the existing oil-level sight-glass and bezel. The monitor
provides a switching facility which you can use to activate an alarm or other device. You still have the normal visual
indication of the oil-level.
7.4.10 Solenoid-operated gas-ballast control valve
The solenoid-operated gas-ballast control valve (see Figure 12, item 2) gives you automatic or remote control of
gas-ballast. You can connect the valve to shut off gas-ballast when the pump is switched off and so prevent air from
returning to the system.
