PROCEDURE FOR
REMOVING COMPRESSOR UNIT
1. Turn off DC power supply breaker for unit.
2. Disconnect the mating plugs of the thermostat control wire
harness approximately one foot from compressor unit.
3. Remove both DC power supply wires from the upper (-) and
(+) screws of the terminal strip module.
4. Shut inlet seacock (if water cool option is installed). Remove
the 2 hoses from the condensing unit.
5. Disconnect the mating plugs of the digital or analog
thermostat located on the condensing unit.
6. The refrigerant in this system must first be extracted by a
qualified technician using approved recovery equipment
before the couplings can be loosened or disconnected.
7. Disconnect both refrigerant couplings. Use two open-end
wrenches: 13/16” hex or 10” adjustable to
turn the female
coupling.
5/8” hex or 10” adjustable to
hold the male
coupling.
8. Turn only the female coupling. Do not turn the male coupling.
If you twist the coupling from its soldered tubing connection,
you will have a refrigerant leak. This is why you must use
two wrenches.
9. Remove the compressor unit from the boat. Handle carefully.
Do not pick it up by the tubing or electronic module. Be
careful not to cut your fingers on the cooling fins and do not
bend them (The fins are soft and thin for maximum
efficiency).
PROCEDURE FOR
REMOVING EVAPORATOR AND TUBE SET
1. Turn the thermostatic control to OFF.
2. Disconnect the 12V DC power supply to the compressor unit.
Carefully remove the sensing tube of the thermostatic control
from its clamp on the side of the freezer by loosening two
screws and sliding out the “U” bend section of the tube.
3. Disconnect both pairs of refrigerant couplings at the
compressor unit (see item 4 of the “Procedure for Removing
Compressor Unit.”)
4. Remove the soft mastic caulking material from the exit hole
into the icebox where the tubing and wire harness pass
through.
5. Using a “stubby” screwdriver, unscrew the four mounting
screws (save these) and carefully withdraw the entire
freezer and its 15 foot tube set from the icebox.
6. Be careful not to kink or flatten the tubing. Screw the plastic
sealing caps into the coupling to keep them clean.
7. Carefully roll up the entire coil by rolling it around a
cylindrical object of about 18” diameter.
PROCEDURE FOR
REMOVING POWERPLATE AND TUBESET
1. Defrost the PowerPlate and thoroughly dry the small
couplings.
2. DIsconnect the 12V DC power supply to the condensing unit.
3. Disconnect the couplings at the PowerPlate, using correct
wrenches and taking care not to turn the soldered-in bases.
4. Install the plastic caps to protect the coupling.
5. Remove the PowerPlate by extracting the mounting screws
and plastic standoffs.
6. Remove the tubeset, first removing the soft self-sealing
mastic at the box exit.
7. Coil the tubeset carefully around a 12” diameter cylindrical
object.
