Attaching Drip Tray

1)The drip tray is mounted on two screws that are located on the lower front of the freezer cabinet.

2)Place the key hole slot of the drip tray support bracket W0471022 on to these screws and tighten the screws.

3)Angle the back of the drip tray surround bracket into the drip tray support bracket W0471022 and lower bracket to lock it into place.

4)Place drip tray onto drip tray surround bracket.

5)Place the louvered drip tray insert into drip tray.

Locating Freezer

1.Locate freezer close to a source of potable water. Water pressure must be 15-psig or higher.

2.Connect freezer to a properly grounded 115-120 VAC, 60Hz single-phase electrical circuit with a 20-amp (NEMA 5-20R) minimum-rated disconnect switch (not provided) that is fused at 20 amps (slow-blow).

CAUTION: Safe operation of this unit can only be achieved if the freezer is properly connected to an appro- priate grounded, electrical receptacle that complies with current national safety standards. The manufactur- er cannot be held responsible for damage and/or injury caused by failure to connect the unit to an appropri- ate source of power.

3. A minimum air clearance of 6" is required on both sides of the freezer during operation.

CAUTION: Restricting air flow through the freezer will greatly reduce the output capacity as this is an "Air cooled" unit. Air is drawn in to cool the unit through the right side (facing front of freezer) and exhausted through the left side. Failure to provide minimum air flow clearance will void the freezer warranty.

Connecting City Water Source Line to Unit

The National Sanitation Foundation requires the following for an NSF approved water hook-up:

•A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning underneath.

•An approved backflow prevention device, such as a double check valve to be installed between the machine and water supply. On units plumbed to permanent water line, installation of a water filter/softener system is recommended to prevent lime and scale build-up in the machine.

•Water pipe connections and fixtures directly connected to potable water supply shall be sized, installed and maintained in accordance with Federal, State, and Local codes.

1)Gather 3/8" OD low-density polypropylene tubing or 3/8" OD copper tubing with a 1/4” SAE Flare Connection (not provided).

2)Connect the tubing to the 1/4” SAE Flare fitting found under the left side of the base unit. (Figure 6)

3)Connect the other end of the tubing to a water source.

NOTE: Where water quality is low an activated charcoal water filter may be needed

 

to achieve adequate frozen product overrun and proper flavor profile.

 

If water pressure exceeds 50 psig install a water regulator such as Shurflo

 

# 183-059-06, or equivalent, to inlet water line.

Installing CO2 Regulator Assembly on CO2 Cylinder

1)Unscrew protector cap (with chain attached) from CO2 cylinder valve. Open CO2 cylinder valve slightly counter- clockwise to blow any dirt or dust from outlet fitting before installing CO2 regulator assembly, then close valve.

CAUTION: CO2 cylinders contain gas under high pressure. Handle cylinders with care.

2)Remove shipping plug from CO2 regulator assembly coupling nut, then make sure gasket is in place inside the nut. Install hose regulator assembly on the CO2 cylinder, then tighten coupling nut. DO NOT OPEN CO2

CYLINDER VALVE AT THIS TIME.

NOTE: Before attempting to activate the systems, insure that all manual shut-off valves, located in the lower back compartment of the base cabinet, are closed (vertical position). Do not open them until instructed to do so.

Installing CO2 Regulator Assembly on Existing CO2 Line

NOTE: Bulk system must have 100 psi to operate.

1)Purchase a low pressure regulator set. (Norgren Model C81-570-2 recommended)

2)Disconnect carbonator and BIB pump lines. Remove existing regulator set and install low pressure set.

3)Reconnect lines to outlet side of set. Bring in bulk system line to inlet of regulator.

NOTE: Install a cutoff valve between regulator and bulk system.
