Maintenance
Cleaning the Filters
Our filtration systems are available in single or multiple
canister configurations. Each canister uses a nylon or
polyester felt filter bag to remove solid particles from
the wash solution. Nylon bags are reusable; polyester
felt bags are designed for a single use. To clean or
replace the filters, perform the following procedure:
1.
Turn off the machine and open the door.
2.
If your machine is equipped with the Auto-Fill
feature, turn off the water at the supply line.
3.
Slowly unscrew the pressure-release plug on the
lid of the filter canister to release the pressure in
the filtration system.
4.
Loosen the three lid nuts, then swing the lid free of
the canister.
5.
Remove and empty the filter bag and screen.
6.
If you are using a nylon filter bag, you can clean
and reuse it several times before replacing it. If you
are using a polyester felt filter bag, you must
replace it. Contact your distributor or call customer
service for filter bag recommendations and
ordering information.
7.
Replace screen and filter bag in the filter canister.
8.
Install and tighten the lid.
9.
Tighten the pressure-release plug.
10. Turn on machine and continue washing.
Repairing The Machine
The following procedures outline the steps necessary
to replace specific items on the machine that could
wear out or otherwise fail.
Heating Elements
Required Tools and Equipment
•
5/16" wrench or socket
•
2" socket and breaker bar
•
sealing tape or compound
•
medium phillips-head screwdriver
Replacement Procedure
1.
Disconnect power to the machine.
2.
Drain the wash solution from the sump.
3.
Remove the cover from the heating element and
thermostat enclosure (four 5/16" screws).
4.
Detach the power leads from the heating elements,
taking care to mark them for reassembly.
5.
Using a 2" socket and breaker bar, unscrew the
heating element(s) from the machine.
NOTE: Since the heating element is in continuous
contact with the cleaning solution the threads may
corrode slightly. The element may be difficult to
remove. When you install a new heating element, use
sealing tape or compound on the threads to deter
corrosion.
