9-8 Maintenance
Draining the Water Trap
The facility air supply may contain moisture that can damage the dispensing system. The water trap
condenses this moisture before it enters the dispenser pneumatic system. The operator or technician
should drain the water trap weekly or whenever it is full.
WARNING! Do not remove the bowl guard protecting the water trap. The bowl is made of
polycarbonate plastic, which could rupture from over-pressurization or if the bowl
has been exposed to chemicals incompatible with polycarbonate. Removing the
bowl guard can result in serious bodily harm to the user.
