COMMISSIONING/STARTING

PROCEDURES

When commissioning a new compressor or one

which has been overhauled or out of service for an

extended period, carry out the following procedure.

1.1 Static Checks

1.

Check that the isolator switch is locked 'OFF'

and that all electrical connections are tight and

correctly made and comply with the wiring

diagram. In the case of Vee-belt drive, check

the belts for condition, tension and alignment.

2.

Check that all blanking covers and protective

tapes have been removed. With oil-free models

ensure that the delivery valves have been taken

from their shipping locations inside the

distance pieces and fitted in the cylinder

heads.

3.

Check that all air intake piping is clean, free

from corrosion and contains no loose debris.

Note:

 If the main air system is being used to

supply delicate instrumentation it is

permissible, for the initial run only, to fit gauze

filters in the air intake line and the downstream

line from the receiver to trap small particles

which may be present, particularly in extended

intake lines. Ensure that all gauze filters are

removed on completion of the initial run. Do

not connect the delivery manifold flange to the

pipework at this stage. The initial run will allow

the cylinder inhibitor, which is slightly toxic, to

disperse without entering the user’s pipework.

4.

Fit the air intake silencer/filter assembly.

5.

If the compressor has been in storage for a

lengthy period, remove all suction and delivery

valves and inspect to ensure that they are in

good condition.

6.

Check that ambient temperatures are within

limits and that ventilation of the compressor is

satisfactory.

7.

Check that the cooling water supply is

adequate and clean and that any water

treatment equipment is in order.

8.

Check that the aftercooler and air receiver are

correctly installed and that the air pressure

relief valves operate correctly.

9.

Prime the lubrication system as follows:

Disconnect the oil pipe between the crankcase

and the oil pressure switch at the switch end.

Connect a pressure oil can to the free end of

the pipe. Remove one of the crankcase doors

so that the connecting rods are visible. With

the recommended oil in the can, pump oil into

the pipe until oil is seen to flow from the small

end bushes. Disconnect the oil can and

reconnect the pipe to the oil pressure switch.

Refit the crankcase door.

10. Remove the oil filler cap and pour in the correct

quantity of the recommended oil (9 or 18 litres,

depending on model). Check that the oil level

is at the maximum level on the dipstick. Refit

the oil filler cap.

z

  Refer to the safety procedures before

operating the compressor unit.

WARNING

z

  Lethal voltages are used in this equipment.

Use extreme caution when carrying out

electrical checks. Isolate the power supply

before starting any maintenance work.
