SEA FROST BD 12 OR 24 VOLT D.C. SYSTEM
With Water Cooling Option
CONDENSING UNIT LOCATION AND MOUNTING
The water-cooling option should be considered supplemental cooling. Installation
should proceed with a proper air-cooled installation first. The water-cooling feature
should be used to enhance efficiency on occasions when cold-wate

Service access and installation requires that the front, left end (inlet) and back (condenser) air outlet be exposed. A duct hose will require 4 inches of clearance past the end of the cabinet. Mount the Sea Frost BD level, (the compressor is at the bottom). The BD may be platform mounted. Two holes have been drilled through the bottom for screw mounting to a shelf or bulkhead. If using the bulkhead mount bracket kit, follow directions supplied with the kit. INSTALLATION REQUIRE

PUMP WIRING Connect the red pump wire to the terminal screw marked pump (+) and the black one to (-) under the compressor housing cover. Be sure the toggle switch is off until the boat is launched and the pump is wet. MOUNTING THE EVAPORATOR PLATE The plate should be mounted in the cabinet as high as possible to take advantage of thermal convection. It may be used as a shelf, mounted on the ceiling or any wall. There is no restriction as to position. Standard aluminum ice tray

KINKING THE TUBES. ALL BENDS SHOULD BE SMOOTH WITH NO LESS THAN A 2" RADIUS. Support the tubing every 18 inches as necessary using tie wraps fastened with self- tapping screws. Insulate at least 3' of the line set as it exits the refrigerator box. Seal both sides of the exit holes in the refrigerator box with permagum sealing compound. WARNING: The Sea Frost BD system is shipped pre-charged with refrigerant. This refrigerant is under some pressure. Do not fiddle with the con

WIRE SIZE 12-volt installations use AWG #10 wire for distances up to 10 feet for the wire pair, and #8 AWG wire for distances up to 25 feet for the wire pair. Fuse 15 Amps. 24 Volts: The module will self calibrate to the applied voltage and provide proper fan voltage. The remote water pump must be a 24volt pump. Fuse 7.5 Amps. If the polarity is reversed, the electronic module will not work. In any application, use the next largest wire if in doubt to prevent a voltage drop.

STANDARD THERMOSTAT WIRING CONNECTIONS Connect the thermostat wires to the yellow wire harness, which is connected to terminals C and T on the module. The yellow wire harness contains a 1500-ohm resistor, which programs the module to operate the compressor at maximum RPM. There is no polarity requirement. STANDARD THERMOSTAT OPERATION The thermostat is attached to the plate. The wires follow the refrigerant lines to the compressor section. Protect these wires from cuts and ch

OPTIONAL REMOTE THERMOSTAT OPERATION Attach the sensing bulb with the bulb clip to one of the lower mounting screws on the plate. The sensing bulb must be in excellent thermal contact with the plate. We recommend that the probe be mounted on the plate in one of the lower mounting positions as shown in the drawing below. This is best because these positions remain colder. The SEA FROST BD thermostat is variable. Turning the knob fully counter

To lower box temperature, rotate this screw counter clockwise. One full revolution will change the box temperature approximately 6 degrees F. To raise the temperature in the box rotate the screw clockwise. Make small adjustments. Record all adjustments. OPERATION DESCRIPTION Once installed the BD is started by turning the thermostat clockwise from the off position. The BD will run until the plate reaches the set temperature of the thermostat. Turning the thermostat clock

DEFROSTING Excessive frost/ice build up on the plate will reduce the cooling effect by insulating the evaporator plate. Allowing the evaporator plate to warm above freezing is one method of defrosting. Boiling water or a scraper will also work. OPERATION INSPECTION Within a few minutes of starting the Sea Frost BD, the tubing in close proximity to the valve mounted on the plate and the valve itself will be noticeably cold. IF AFTER 20 MINUTES OF OPERATION, COOLING IN THIS ARE

TROUBLESHOOTING A light emitting diode (LED) is connected between terminals + and D. In case the electronic unit records an operational error, the diode will flash a number of times. The number of flashes depends on what kind of operational error was recorded. Each flash lasts 1/4 second. After the actual number of flashes there will be a delay with no flashes, the sequence for each error recording is repeated every 4 seconds. Flashes will only occur in the fault mode with the sys
