Pressure Relief Procedure
NOTE: Relieving air pressure in the machine means
that the supplied dry air will be replaced by moist
air. Do not leave the machine exposed to moist air
for more than 30 minutes. If the machine must be
left without air pressure for more than 30 minutes,
the day tanks must first be emptied and thoroughly
flushed.
1. Turn off main power.
2. Close day tank incoming air supply valve.
3. Disconnect pressurized air supply hose from water
separator.
4. If applicable, disconnect the air line from the air
motor air inlet.
5. Open the pressure relief valve on top of each day
tank to bleed air pressure from system.
6. Ensure there is no air pressure in the tanks; look at
the pressure gauges.
