Replacing Replenishment Pump Developer And/Or Fixer - JPI JP-33 Service Manual

Technical Support
A. Replacing replenishment pump Developer and/or Fixer.
NOTE
: The developer and fixer replenishment pumps are identical in appearance and
wiring. Identify the correct pump before execution. If the two pumps are being replaced,
make sure to replace each pump separately (Remove and replace pump one and then work
on pump two).
1. Make sure unit is turned off and chemistry is drained.
2. Remove hoses from pump nipple.
3. Disconnect the green wire with yellow stripe (Ground wire).
4. Identify the two screws holding the pump in place and remove them.
5. Disconnect the remaining wires.
6. Only when replacing Developer pump, remove the (red/burgundy) cover from the
new pump, then replace it with the cover of the old pump. This will insure the
pump fits properly in its original position. When replacing fixer pump use the new
pump with the new cover.
7. To install the new pump attach the two (green) power wires to the brown and white
wires (Alternative current) wiring position does not matter. Place and screw pump
into position, make sure bare wires are not exposed and wires are placed snug in
original position.
8. Connect the hoses securely: There are directional arrows on the nipples; the
arrows are pointing in the direction the fluid will flow. Please identify the exit
hose and entry hose and connect them to the corresponding nipple.
9. Make sure to strap any loose wires and check for leaks.
