Servicing Circulation Pumps (Cont'd)
The circulation pumps are easily removed for cleaning and/or servicing. For the later
style pump (Figure 5-3, Serial #'s starting at 8724 and above), proceed as follows:
Removal
1) Unplug the processor from its power outlet.
2) Drain the tank from which the pump is to be removed.
3) Disconnect the pump power cable from the plug channel.
4) Disconnect the inlet elbow and output hose from the pump body.
5) Loosen the two (2) screws securing the pump mounting feet to the bracket. Slide
the pump mounting feet out from under the tabs provided on the bracket and remove.
Disassembly & Cleaning
Developer recirculation pumps are usually cleaned adequately by systems cleaning and
do not require disassembly.
Fix and wash pumps should be disassembled for cleaning at least once a year to remove
hardened residue build up.
Disassemble and clean as follows:
1) Remove the four pump head assembly screws, (Figure 5-3). Be careful to note the
orientation of the outlet nozzle for reassembly.
2) Gently separate the pump head assembly. Locate and save the internal “O” ring
seal inside the pump head.
3) Remove the impeller from the pump head, taking care to not lose the small green
spacer located on the inside of the indentation of the impeller and thoroughly clean
all pump head parts in warm water.
Assembly
1) Reassemble the pump in reverse order. Lubricate the internal “O” ring with a
silicone base lubricant before installing. Take care to not lose the lock washer and
flat washer provided with each screw and do not over tighten the screws.
Installation
1) Carefully install the pump in reverse order of removal. Lubricate the 5 “O” rings
that seal the pump to the tank base with a silicone base lubricant before installing.
2) Test the pump for operation with water before installing chemistry.
