Replacing Whipper Motors on Machines Manufactured Prior to Fall 1998:
1. Left motor may be changed with 61116-01 (round motor) if you install a single pole switch
(part # 61847) in place of the existing power switch.
2. Middle motor may be changed with 61116-01 directly.
3. Right motor can only be changed with 61116R (Oval (double-D) shaped motor).
Replacing Whipper Motors on Machines Manufactured After Fall 1998:
1. Place motor in mounting location, install lock washers and loosely tighten acorn nuts on motor mounting
studs. Hold motor while shaft is centered inside hole then tighten nuts securely.
2. Install white slinger washer over the motor shaft and up to hopper mounting bracket.
3. Lubricate inside of whipper base then install over the motor shaft and check alignment of holes. If alignment
is off, rotate base 180° to make sure holes line up. Hold base securely, and carefully tighten mounting
screws.
4. Check the motor shaft to ensure it can turn freely with fingers. If shaft is still hard to turn, reposition motor
and repeat.

Purging Machine of All Water for Shipment in Cold Areas
WARNING: This procedure should be performed by a qualified service technician.
1. Turn the power switch to the "OFF" position.
2. Drain the water tank (refer to instructions on page 12). Do not replace the drain hose plug and clamp until
further instructed.
3. Turn the power switch to the "ON" position. The ready light should turn itself "ON" within 12 seconds. The
12 second delay signals that the heating element has been disabled due to the lack of water in the tank
after it is drained.
IMPORTANT: If the ready light does not turn itself "ON" within 12 seconds, turn the power "OFF" to avoid
burning out the heating element.
4. Listen for the inlet valve to energize. To purge the inlet valve and water inlet tube, apply 10-20 psi
compressed air to the inlet valve connection for 10 to 20 seconds while the inlet valve is energized.
NOTE: Do not energize the inlet valve for more than 5 minutes at a time. Otherwise, the watchdog timer will
disable the inlet valve. If this occurs, reset the machine by flipping the power switch “OFF” then “ON”.
5. After the inlet valve and water inlet tube are purged, purge the dump valves and dispense lines. While
applying 10-20 psi compressed air to the inlet valve connection, press and hold each dispense button for
1-2 seconds.
6. Turn the power switch to the “OFF” position. Replace the drain hose plug and clamp. Reposition the drain
hose inside the hose clip on the left side wall.
7. Reassemble the front access panel and drain tray.
