5. Remove the screen, examine any particulate that have accumulated and clean the screen
thoroughly with a wire brush.
6. Reinstall the screen, cover (use a new gasket), screws, and plug. Open valves A, B, and C.
Refer to the thermal fluid system diagram for valve nomenclature details.
7. Purge the air from the system as described in the Thermal Fluid Filling procedure starting at
step 10, found earlier in this manual.
5.8.4 Pump Service
For pump service instructions and parts information see the thermal fluid pump manual in the
Appendix. To drain the pump for service proceed as follows:
1. Cool the ironer to 60C or lower (perform the procedure first thing in the morning when the
machine is cool if possible).
2. Close valves A, B, and C. This isolates the pump and filter screen for service so a minimal
amount of fluid is lost during the procedure. Refer to the thermal fluid system diagram for
valve nomenclature details.
3. Remove the plug in the bottom of the filter screen cover and drain the fluid into a metal oil
safe plastic container at least 2 gallons in volume.
4. Service the pump as needed. It is recommended that you also clean the filter screen at this
time.
5. Reassemble the pump and reinstall the screen if removed.
6. Double check your work! Is everything assembled properly and sealed?
7. Open valves A, B, and C. Refer to the thermal fluid system diagram for valve nomenclature
details.
8. Purge the air from the system as described in the Thermal Fluid Filling procedure starting at
step 10, found earlier in this manual.
5.8.5 Thermal Fluid Draining
Before draining the thermal fluid, make sure you have a container for it. The container size needed
will vary with the the particular model of your ironer. To drain the system follow this procedure:
1. Cool the ironer to 60C or lower (perform the procedure first thing in the morning when the
machine is cool if possible).
