Maintenance
In order to guarantee optimum operational reliability and service life of the compressor,
we recommend
carrying out servicing and inspection work at regular intervals:
Oil change:
-
not mandatory for factory-produced series systems.
-
for field installations or when operating near the application limit: for the first time after 100
to 200 operating hours, then approx. every 3 years or 10,000 - 12,000 operating hours.
Dispose of used oil according to the regulations; observe national regulations.
Annual checks:
Oil level, leak tightness, running noises, pressures, temperatures, function of
auxiliary devices such as oil sump heater, pressure switch.
WARNING! Before starting any work on the compressor:
Switch off the compressor and secure it to prevent a restart.
Relieve compressor of system pressure.
Prevent air from infiltrating the system!
After maintenance has been performed:
Connect safety switch.
Evacuate compressor.
Release switch-on lock.
6.8 Connection of oil level regulator
Oil level regulation systems have proven themselves with parallel circuits of several compressors.
The connection "0" is provided for installing an oil level regulator (see dimensions drawing). All
common oil level regulators from AC&R, ESK and Carly as well as the OM3 TraxOil oil level regulation
system from Alco can be connected directly without adapters (see Fig. 21). A sight glass on the oil
level regulator is not required.
