2.4 FREEZER INSTALLATION
WARNING
Installation must be completed by a qualified electrician/refrigeration specialist.
Incorrect installation may cause personal injury, severe damage to the machine and will void factory warranty.
Before installing the freezer, make sure you have the following tools:
• Refractometer
• Stopwatch
• Graduated Cup
• 5/32” Hex Wrench
• 5/16” Nut Driver
Installation of the freezer involves moving the freezer close to its permanent location, removing all crating, setting in place, making connections, assembling parts, and cleaning.
A. Uncrate the freezer. B. Accurate leveling is necessary to ensure proper
operation. Place a bubble level on top of the freezer at each corner to check for level condition. If adjustment is necessary, level the freezer by turning the bottom part of each leg in or out.
C. Freezers require a minimum of 5" (12,7 cm)
clearance on the sides and an open top for proper air circulation.
2.5 CONNECTING SYRUP, WATER AND CO
The connections for syrup, water and CO2 are located at the back of the freezer (Fig. 2-2). The fittings are 1/4” flare nuts.
2
A. BAG-IN-BOX (BIB) SYRUP SUPPLY
A BIB syrup supply is required for each freezing cylinder. The syrup supply must have a pressure of 68-72 psi.
1. Run 1/4” braided tubing from each BIB to the rear of the freezer.
2. Connect the syrup lines to the 1/4” flare nuts at the rear of the freezer.
3. Do not turn on the syrup supply yet.
B. WATER SUPPLY
The freezer requires a filtered fresh water supply with a pressure between 30-110 psi.
NOTE
Water pipe connections and fixtures directly con­nected to a potable water supply shall be sized, in­stalled and maintained in accordance with federal, state, and local health codes.
NOTE
A backflow prevention device that conforms to ASSE 1032 or ANSI/ASSE 1022 must be installed up­stream of the CO2 injection system.
1. Use 3/8” braided tubing for the water supply.
2. Install a shutoff valve in the water supply line near the freezer connection.
3. Flush out 2 gallons of water before connecting the water supply to the freezer. Depending on the age of the plumbing, there may be sediments that have loosened from working with the piping. Flushing water out will prevent that sediment from entering the freezer and causing an obstruction in the water line.
3. Connect the water line to the 1/4” flare nut at the rear of the freezer.
4. Do not turn on the water supply yet.

value, the mix solenoids will open.
Mix Fill Off
When the pressure in the cylinder equals this
value, the mix solenoids will close.
Serve Ready LED
The LED will turn off when this percentage of
consistency has been met.
Offset
Offset is a percentage of consistency in the
cylinder. If a freezing cycle is running on another
cylinder, Offset determines if the cycle will run for
this freezing cylinder.
Max On
Max On is the maximum time that a freezing cycle
will run. An error will be logged if this time is
exceeded. The compressor will still operate.
Standby
If the Prime button is pressed and the On button
is not pressed, this is the amount of time that the
control will wait until going into standby mode.
Carbonization
Turn carbonization off to make non-carbonated
frozen beverages.
B. ERROR CONTROL SETTINGS
The error control settings determine the length of a freez­ing cycle if there is an error condition.
Default Frz On
This setting determines the length of a freezing cycle when product is being kept in a frozen state.
Default Frz Off
This setting determines the length between freezing cycles when product is being kept in a frozen state
Default Liq On
This setting determines the length of a freezing cycle when product is being kept in a liquid state.
Default Liq Off
This setting determines the length between freezing cycles when product is being kept in a liquid state.
C. DEFROST SETTINGS
The freezer has two types of defrost: Sleep Defrost and Power Defrost. Following are the available adjustments to the defrost settings.
Sleep Defrost
An energy-savings defrost type where the compressor does not run. The Sleep Defrost can be set to run during Idle periods or at specific Times. The freezer will remain in the Sleep Defrost mode until the On button is pressed.
Power Defrost
This is a rapid defrost type in which the refrigerant flow bypasses the condenser. This rapidly thaws the mix in the cylinder. The Power Defrost can be set to run during Idle periods or at specific Times.
NOTE
After a power defrost, allow the freezer to operate a while without serving product.
Idle
This is the amount of time that elapses before the defrost starts.
Time
This setting is the hour and minute of the day that the defrost starts. Up to three different times can be set.
D. USER PREFERENCES Language
The language can be set to English or Spanish.
Units of Measure
The freezer can be configured to display Fahrenheit (ºF) or Celsius (ºC).
14
E. TIME AND DATE
The freezer has an internal clock that keeps track of the time and date. The clock can be set for 12-hour or 24-hour time and can automatically adjust for daylight savings.
4.5 UTILITIES

4.7 CONDENSER CLEANING
The condenser requires periodic cleaning. To clean the condenser, refer to the following steps:
A. Remove a side panel and pull the condenser filter
out of its bracket. B. Visually inspect the condenser filter for dirt. B. If the condenser filter is dirty, vacuum or brush it
clean. Rinse it with clean water and allow it to dry
before replacing it on the freezer.
NOTE
If the condenser is not kept clean, refrigeration effi­ciency will be lost.
On Demand Defrost
This option will run a power defrost on the selected cylinder.
Restore Factory Defaults
All changes made to settings will be replaced by the original factory defaults.
