Maintenance

Basic Maintenance
The modules require minimal maintenance. However, process fluids must be changed and
added periodically as necessary. Completely replace the process fluid every two years.
To drain the process fluid when servicing the machine, use the following procedure:
Press the Start/Stop key to enter idle mode, then toggle the power switch off.
Depressurize the fill canister by unscrewing the trigger assembly from the top of the
canister. Leave the bottom hose of the trigger assembly in the canister but do not screw
back in place.
Connect the fill canister hose to the quick disconnect fitting on the bottom of the module
labeled Drain.
Open the Fill and Service valves.
Press the trigger on the canister and the process fluid will drain into the canister.
Disconnect hose when process fluid is completely drained from the module.
Close the Fill and Service valves. The equipment is dry and ready for servicing.
