/////////////////////////////WARNING//////////////////////////////////

Disconnect electrical power before beginning.

/////////////////////////////////////////////////////////////////////////////////

Water Pump

1. Remove front panel.

2. Remove evaporator cover.

3. Unplug water pump electrical connection.

4. Remove thumb screw retaining pump to cross
brace.

5. Pull pump partially out of reservoir and remove
discharge hose.

6. Remove two nuts holding pump cover to pump
body; separate the two and remove the pump from
the icemaker.

7. Reverse to reassemble.

8. Replace all panels.

9. Reconnect electrical power.

Hot Gas Valve

1. Remove the side service panel, and top panel if
possible.

2. Discharge and recover the refrigerant from the
system.

3. Remove the electrical connections from the coil
of the valve

4. Cut out or unsweat the valve at the tubing
connections, remove the valve from the icemaker.

5. Install the new valve, wrap it in wet cloths or
other efficient heat sink material.

6. Sweat the tubing connections to the valve.

7. Connect the electrical wires to the terminals of
the valve coil.

8. Weigh in the nameplate charge.

9. Replace all panels removed for service.

10. Reconnect electrical power.

Thermostatic Expansion Valve

1. Remove the side service panel, and top panel if
possible..

2. Discharge and recover the refrigerant from the
system.

3. Locate the TXV sensing bulb on the suction line,
unwrap the insulation and remove the bulb from
the clamp.

4. Cut out or unsweat the old TXV from the tubing
connections.

5. Wrap the new TXV body in wet cloths or other
efficient heat sink material.

6. Sweat in the new valve. Do not overheat.

7. Re-attach the TXV bulb to the suction line in the
same place as the original. Be certain to
re-insulate.

8. Weigh in the nameplate charge.

9. Replace all panels removed for service.

10. Reconnect electrical power.
