Install Tubing and Re-Assemble the Cooling Water Pump Head
1. Hold the released end bell with the tubing retainer grooves pointing
down.
2. Center the tubing in the right groove and against the first two rollers.
Hold the tubing with your thumb.
3. With the other hand, working counterclockwise, wrap the tubing
completely around the rotor, pushing the tubing into the bell assembly.
When the tubing has wrapped completely around the rotor, hold the
second end in place.
4. Position the end bell with the tubing on the end bell in the console.
Ensure that the flat end of the pump drive shaft fits into the slot on the
end of the motor coupler.
5. Replace the two screws (8 - 32 Phillips) that attach the end bells.
Note: If a gap remains between the two end bells after you position
them together, the pump head may pinch or cut the tubing. Rotate the
pump shaft until the gap disappears.
6. After determining that no gap exists between the end bells, tighten the
two screws.
7. Trim the length of the new tubing to reach the cooling water tube
fittings.
8. Connect the tubing to the fittings, and replace the wire ties on the
fittings. The kit includes two extra wire ties in case you break or lose
one.
9. Replace the left side cover.
10. Plug the power cord connector into the wall receptacle.
11. Turn on the AC Main Switch, located on the rear panel.
