Partition for adjusting box temperatures
(Fig. I)
Cold air from the holding plate sinks down to
the bottom of the box. The box, therefore,
needs a separate space to enable part of it to
be used as a freezer compartment. To
achieve best results, this compartment should
be no larger than absolutely necessary. The
dividing partition should be a tight fit against
the box sides and reach a height of
approximately 5 cm (2 in.) below the top edge
of the holding plate.
It should be able to be adjusted vertically from
0-2 mm to create a gap at the bottom to allow
a suitable amount of cold air to flow from the
freezer section into the refrigeration section to
maintain a temperature of +4-6°C (39-43°F).
The dividing partition should not be insulated,
be easy to clean and preferably made of
transparent Plexiglas.
Compressor unit
The compressor unit should be fitted on the
"Click-on"-bracket in a horizontal position in a
suitable place such as a cupboard, wardrobe,
stowage compartment, etc. The unit can also
be mounted onto a suitable bulkhead, under
the side decks or any other place where no
valuable stowage space will be lost. If it is
positioned in a stowage place, a guard may
be required for protection.
The unit will operate continuously at angles of
up to approx. 30° and should therefore be
fitted horizontally across the beam of sailing
boats so as not to exceed this at full angle of
heal. Screw the bracket carefully to the
bedding, either horizontal or vertical. Open
the lockings by pulling them aside and lift
them up slightly. They will then stay in open
position. Lower the compressor to the
bracket. The rubber feet shall enter the pins.
Push the compressor down a little and the
lockings will enter locked position. Check that
the compressor is safely locked. Installation
can often be simplified if the quick-coupling
connections on the piping and the com-
pressor are screwed up tight before the
compressor unit is finally put down in position.
Do not remove the protective caps until
immediately before this is about to be done
and save them for possible future use.
The quick-coupling connections can be turned
by hand for the first few threads before
continuing tightening steadily and quickly with
a spanner so that the connections enters its
sealing position and the valves open. While
doing this, it is important that the male part of
the connection stationary is held with a 21 mm
spanner so that it does not rotate and damage
the thin capillary tube (see Fig. D). Tighten the
couplings up hard. Use fixed spanners 21 and
24 mm for the pipe fittings.
Control panel
The control panel should be positioned where
it can be seen easily and within reach of the 4
meter cable from the electronic control box on
the compressor. The housing can be mounted
using the accompanying long screws. A 12
mm Ø hole should be drilled for the cable. The
panel can also be let into its surrounding by
removing the plastic housing and attaching it
with the accompanying screws.
Electrical wiring
Run a positive lead from the plus (+) terminal
of the battery or the battery main switch
across the accompanying fuse holder (Fig. F)
and a negative lead from the negative (-)
battery terminal.
For a 12 Volt system, the minimum area of
the cable from the battery to compressor
must be: 2.5 mm² if the length is less than
2.5 meter; 4 mm² if up to 4 meter; and 6
mm² if up to 6 meter.
USA wire size: 12 gauge for 10 ft and under
and 10 gauge for lengths over 10 ft.
These areas can be halved for a 24-volt
system.
Connect these cables to their correct tab-type
terminals on the control unit. A battery charger
must never be connected directly to the
refrigeration system without having a battery
connected in parallel (See Fig.)
A spark occurs when the power leads are
connected. This is because the control unit
(which consumes only 16 mA in its closed
circuit condition) contains a capacitor, which is
then charged.
Connect the two modular plugs in the front of
the control unit with the control panel cable
plug connected to the lower larger one and
the temperature sensor to the upper
connector. (See Fig.)
