Removing the Pump
1. Drain the coolant (See “Changing the Coolant” on page 13).
2. Remove the load (See “Replacing Resistor Assembly” on page 20).
3. Disconnect the pump wire leads from the terminal block on the inside of
the front panel.
4. Loosen the hose clamps on the input and output hoses to the pump, and
remove the hoses.
5. Unscrew the hex nut on the drain tube at the base of the pump. Remove
the drain tube.
6. Unscrew the bolts securing the base of the pump to the unit.
7. Remove the pump, carefully, from the unit.
8. Note the position and direction of the fittings, then twist them off counter-
clockwise.
9. To replace the pump, reverse the above steps.
 Note: When replacing the threaded fittings, carefully coat the
external threads, ONLY, with a pipe sealing compound. Coating only
the external threads reduces the chances of contaminating the coolant.
WARNING
To avoid personal injury, disconnect the power cord from the AC line before
performing any maintenance, including fuse replacement.
