DESCRIPTION
The Sea Frost Freezer system consists of several parts: The cold plates or wrapped
box liner (hidden cooling coils), a refrigerant control valve, copper connecting lines, a
receiver filter drier with sight glass, a compressor / condensing unit and a thermostat.
OPERATION
With the thermostat in the "on" position, the compressor, fan, and pump (if equipped)
will operate. Ten minutes after starting the compressor the area near the valve or the
top of a hidden coil box will begin to cool and frost.
If you do not observe cooling, with the compressor and fan running, switch off
the unit to avoid damage.
Within a few minutes of starting the Bait Freezer, the tubing in close proximity to the
valve and the valve itself will be noticeably cold. (If after 20 minutes of operation the
cooling in this area is not observed, do not continue to operate the system.)
After several hours, the box temperature will cool to well below freezing.
The first plate or the top section of a wrapped box will cool first. Because it freezes first,
all the moisture suspended in the air within the box condenses and freezes at this plate.
Frost is not a good indication of proper operation; check the temperature with a
thermometer. When the box and contents cool to the desired setting, the compressor
and fan will cycle on and off periodically to maintain the set temperature.

- Page 2 CONDENSING UNIT LOCATION AND MOUNTING Air Cooled The design of the Bait Freezer (BF) allows the air-cooled condensing unit to be placed in an enclosed space such as a locker or engine room. Mount the unit level with the compressor at the bottom. The unit may be bulkhead or platform mounted.

Page 3: Quick Connect Fitting Instructions
EVAPORATOR PLATE INSTALLATION Mount the plates on opposite walls as high as possible to take advantage of thermal convection. Install the plates with the Wellnut, spacers and screws provided. The plate(s) mounts with a Wellnut expandable neoprene blind hole fastener. A template or the plate itself should be used to locate the mounting holes. -
Page 4: Expansion Valve
The constant pressure valve sets the refrigerant boiling point. The pressure setting will indicate the minimum temperature that the freezer system can obtain. It has been pre set at the factory. Observing the low side pressure with gauges, note that the pressure is constant at 2 to 8 psi. - Page 5 Installing a Jumper If installing a multi plate system, use the jumper to connect the remaining tube on the first plate to either tube on the second plate. Installing the Return Line Connect a return line to the remaining tube. This return line connects to the compressor.
- Page 6 Thermostat Operation The thermostat is pre-set and locked at the factory. disabled and changes to the settings cannot be made. To change the settings the lockout switch must be placed in the unlock position. To access the lockout switch: 1. Switch off the power. 2.

Page 7: Reading The Sight Glass
220-VOLT CIRCUIT A separate 10-amp breaker is required for the 220-volt supply. This circuit powers the thermostat through a built in transformer. For operation, it is necessary to have power at all times. RE-CHARGING OR ADDING REFRIGERANT Adding refrigerant will not change the suction (low) side pressure. Do not charge more than 12 oz of R-134a in an empty system. -

WARNING: A clear sight glass can also indicate a completely EMPTY system. Anytime the compressor is started, white foam should appear in the sight glass indicating that the refrigerant is present. This foam may disappear quite quickly but, IF NO FOAM IS EVIDENT and the system is not cooling, the system is empty. - Page 9 16" Width 14.5" Depth 7.5" Cooling Ducted Air Cooled Compressor unit 36 lbs weight Bait Freezer Specifications BF 2 1.9 @ 220 volts 760 @ -10 F. 16" 14.5" 7.5" Ducted Air and Water Cooled (remote water pump required) 36 lbs...
