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. Rubber Wellnut inserts are installed on the bottom and back of the condensing unit to attach to brackets or shelving. The Wellnut require ¼-20 machine screws. Air and Water Cooled The

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. Drill a 3/16" pilot hole. Increase this hole to 3/8". Install the screw into the plate through the spacer then tighten the screw in

EXPANSION VALVE The expansion valve/ liquid line/drier connects to one of the plate fittings and at the discharge fitting on the compressor section. After assembly externally mounted, valves will need to be insulated to prevent frost and sweating. Installers Set up 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

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. Support the tubing every 18 inches as necessary with mountable tie wraps and self taping screws.

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. Typical head pressure will be about 25 degrees above air temp. If you are adding refrigerant and exceed the

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. DO NOT OPERATE THE SYSTEM in this empty condition. Operation in this mode will ruin the compressor. Turn off the main breaker to the control panel to prevent operation unt

DEFROSTING The unit will require defrosting from time to time as the frost layer builds up. Allowing the unit to warm above freezing is one method of defrosting. Warm water or a hair dryer is also a quick method. Plates can be scraped with a spatula or ice scraper to remove excessive frost build up.
