Installation
2.4.3 Setting the Outlet Pressure
Outlet pressure is adjusted by rotating the knob on the Filter/Regulator unit – see
Fig. 2.2 item 3, clockwise adjustment increases the pressure. The setting can be
locked by depressing the knob.
2.4.4 Using The Compressor
The compressor has a maximum 50% duty cycle, which means that the motor must
not be allowed to run for more than 50% of the time the compressor is in use. The
motor must never be allowed to run continuously otherwise it will overheat and may
become damaged.
Do not ignore air leaks. All air connections must be leak free to prevent the
compressor from overheating.
The motor control box incorporates a thermal overload protector which cuts the power
if the oil temperature is too high – see Fig. 2.1. If the cutout operates, allow the
compressor to cool down (approx 50 mins) before restarting and ensure adequate
airflow around the unit (see Section 2.1 – Siting).
Cautions
.
The thermal overload protector is set at the factory and should not be adjusted.
You must rectify the cause of the overload before continuing to use the compressor.
Check for:
Drain tap not closed properly
Air leaks on the pneumatic fittings
Excessive workload on compressor, e.g. running too many systems from one
compressor.
