If the machines are to be stopped for a prolonged period of time the following rules should be applied:
Before turning equipment back into operation, a visual inspection is needed.
First turn off the power supply to the air compressor, remove the drive shaft protection guard and turn the drive coupling to check that the compressor is free to turn. If the compressor turns freely, re-fit the guard and turn on the power supply to the compressor; turn on the cooling water if the compressor is water cooled. Slowly open the compressor air discharge valve until the air pressure equalizes between the compressor and the air net. Start the compressor. The compressor is now back online. If the air compressor is connected to a sequence controller, make sure the compressors are integrated onto the controller/ Optimizer.
For adsorption dryers and gas generators never start up against an empty air-net. When starting close the outlet valve behind the dryer or generator and pressurize the system. Then slowly open the outlet valve to pressurize the air-net, this to avoid high air speeds damaging the adsorption material.
