6.6 COOLING
Satisfactory compressor operation depends on correct cooling, which requires positive circulation of cool,
clean water, free from suspended particles.
Check water is flowing in mains installations or, if closed circuit, that radiator is full.
It is recommended that a filter be fitted in the inlet water line (mains).
Maximum permitted water pressure within the compressor is 5 bar equivalent to 52 metres of water head.
Cooling water flow rate is determined by temperature rise across the machine adjusted on site to 10°C to
12°C.
Maximum recommended water inlet temperature is 37°C.
It is recommended that temperature gauges are fitted to water inlet and outlet pipes to monitor water
temperature (mains).
Water flow rate at 15°C inlet temperature will be 75 l/h/kw approximately (mains).
Prevent overcooling by shutting off flow when compressor is not running (mains).
A CompAir automatic water valve can be fitted to control water supply when stopping or starting the
compressor (mains).
Trip arrangements should be fail safe to ensure that compressor will only run on full load for a short
period without water flow before shutting down.
During freezing weather conditions, cooling water should be drained from the system if the compressor is
not being used (mains) or anti-freeze added to radiator sets to manufacturers specified concentrations.
NOTE:-
It is essential that anti-freeze used is suitable for use with neoprene rubber water pump impeller when
Jabsco cooling water pump is supplied with compressor or radiator set.
The following are suppliers that have indicated that their products are suitable for use with neoprene
rubber.

The above named anti-freeze followed by * suffix includes a rust inhibitor.
Cooling Towers and Chillers Consult the local Water Authority and specialists dealing with these systems
for frost protection recommendations.
6.7 ELECTRICAL CONNECTIONS
Ensure compressor is installed to comply with local electricity authority stipulations and that necessary
electrical work is carried out by a qualified electrical engineer. Check electrical requirements for machine
with manufacturer before commencing installation wiring.
