D. The overrun setting is indicated by a pointed pin.

E. To adjust overrun, loosen the allenhead screw (located within the center of the adjustment knob) with the 5/32" (4mm) allen wrench provided. Rotate the adjustment knob counterclockwise to a higher number for higher overrun, or clockwise to a lower number for lower overrun. Each number multiplied by 10 represents the overrun percentage (ie: #4 = 40% overrun).

F.Tighten the allen screw, then place the wrench back in its clip. Replace the lower back panel and secure with the four screws. Turn the mix pump power switch to the ON position.

4.4MIX PUMP HOSE REPOSITION (every one or two weeks.)

NOTE

Mix pump hose must be repositioned every 1 - 2 weeks. Failure to comply will result in reduced mix pump liquid capacity, dispense stoppage, popping, and possible mix pump hose leakage.

1.Run cleaning solution through pump.

2.Turn pump off and relieve any pressure by opening the spigot.

3.Grasp the pick-up hose end of the mix pump hose with one hand and turn the pump on. Pull down on the pick-up hose end until 12 to 14" (30-1/2 to 35-1/2cm) of tubing has reverse fed through the pump, then turn the pump off.

4.Loosen small clamp at the pick-up hose adapter and (Viewed from Back) disconnect mix pump hose.

5.Cut 7-1/2" (19 cm) off the end of the mix pump hose.

6.Reconnect mix pump hose to adapter.

7.Continue normal operation. Mix hose will automatically reposition itself with adapter near black cover.

NOTE

Each hose is long enough for 3 repositions before replacement is required. Record each event on Hose Service Record decal.

4.5 MIX PUMP HOSE REPLACEMENT

NOTE

Mix pump hose must be replaced when tubing cannot be further repositioned (every four to eight weeks). Failure to comply will result in hose failure and possible pump damage. See Section 2.5 for instructions on mix pump hose replacement.

4.6 DRIVE BELT TENSION ADJUSTMENT

To check belt tension, refer to Figure 30 and follow the steps below:

WARNING

Hazardous Voltage and Moving Parts

Never attempt to repair or perform any maintenance on freezer until all main electrical power to freezer has been disconnected. Failure to disconnect electrical power before servicing may result in

serious injury or death.

A.Remove either side and back panels.

B.Press firmly on one belt. Figure 30.

C.When the tension is properly adjusted, the belt should deflect approximately 3/8" (about the width of the belt).

Figure 30. Belt Adjustment

D.If an adjustment is necessary, remove the side panel. Turn the jack screw located on the motor bracket, clockwise to increase belt tension or counterclock wise to decrease belt tension.
