4.5 Draining the Water Trap
Because the facility air supply may contain moisture that can damage the dispensing system, the
DispenseMate is equipped with a water trap that condenses this moisture before it enters the pneumatic
system. The operator or technician must drain the water trap weekly or whenever it is full.
Tools and Materials Needed:
• Container for wastewater
To drain the water trap:
1. Locate the water trap at the rear of the system.
2. Shut off facility air pressure and disconnect the
facility air supply from the main air pressure
regulator inlet (Figure 4-3).
3. Hold a container under the water trap to catch
the water and open the water drain knob by
turning it counterclockwise.
4. After the trap has been drained, close the water
drain knob by turning clockwise.
5. Reconnect the facility air supply to the main air
pressure regulator inlet.
