Mounting evaporator
The evaporator unit should be positioned as high as possible
in the fridge. O-evaporators should preferably be installed ho-
rizontally to simplify making ice-cubes. Drill a Ø 30 mm (1¼")
hole in the fridge wall and possible bulkheads for the fl extube
and couplings to pass through. (Fig. 4). Before installing the
evaporator, carefully unroll the pipe and small capillary tube
to their full extent.
Always keep the protection caps on the couplings until they
are about to be connected. Starting from inside, pass the
pipe with its two connections through the hole and bulkheads
to the compressor taking care not to kink or fl atten the tube.
As the tube is pre-fi lled with refrigerant, it cannot be shorte-
ned. Excess tubing should be neatly coiled and secured to
prevent vibration and noise. This must be done before the
quick-couplings are connected. (Fig. 4) Fill the hole in the box
wall with sealant or foam.
Use the distances when fastening the evaporator to the wall.
The fl at evaporators can be bent one or two times to cover
several sides of the box. (Fig. 6)

Mounting thermostat
The thermostat control box can be installed either inside or
outside the fridge. Check that the thin sensor tube is long
enough so that its end may be attached to the evaporator,
min 70 mm (2¾") ,either with the screw-bracket in pre-dril-
led holes or with the clip on the edge of the evaporator. On
larger fl at evaporators, mounting the clip on the upper edge
compared to the lower edge, means a temperature difference
of up to 5°C/9°F. Upper edge means colder box temperature
with the same thermostat setting. (Fig 7)

Connect the thermostat cables to the electronic unit, to C, P
and T tabs, see wirig diagram fi g. 5. Models with larger eva-
porators also have a resistor on the cable connection at the
T tab, for compressor speed setting, to medium or maximum
speed.
(Fig. 5)
Quick couplings
The quick-couplings can now be connected. To start with, pull
forward the tubes on the compressor. Connect fi rst the thin
capillary tube. Rotate the female coupling nut only. The
male coupling must be held stationary or the thin tube will be
broken. Screw the couplings to the bottom of their threads,
tighten fi nally fi rmly using fi xed spanners 21 and 24 mm.
(Fig. 8)
Do not throw away the protection caps. Should it be requi-
red to re-position the unit, the couplings can be re-opened
without the refrigerant escaping. In such a case, screw in the
protection caps immediately and tighten fi rmly.

Start up
Testing the installation is carried out by turning the thermo-
stat knob clockwise. The compressor should start within 30
seconds and a low humming noice will be heard. The fan will
start at the same time. After a few more minutes the evapo-
rator will start to frost. The thermostat regulates the tempera-
ture so it will be coldest at its maximum setting clockwise and
warmest just after the switch on position.
Shut-off by turning the thermostat knob anti-clockwise to the
STOP-position. A certain spring resistance shall be passed.
Maintenance
Maintenance is not normally required and the complete
refrigeration unit may remain in the boat during winter. To
maintain effi ciency, remove any dust that may have collected
on the condenser every season.
It is recommended to defrost the fridge when the evaporator
has a frost layer of 4-5 mm.
Shore power
A battery charger must always be connected to the battery,
never directly to the refrigerators electroninc unit.
The battery charger shall have a capacity of at least 10A.
Another, better, solution is to install our Power Pac conver-
ter which automatically switch from battery to shore power
supply when the shore power is connected .
