3.1 Battery voltage sensor
To protect the batteries from becoming completely
discharged, a battery voltage sensor switches off the
compressor automatically at the following levels:
System voltage V
Cut out V
Cut in V
12
9,6 (10,4)
10,9 (11,7)
24
21,3 (22,8)
22,7 (24,2)
If the bridge between C and P is cut off, values within the
() are valid.
4 Installation instructions
Many boats have a space which is intended for a freezer.
The Isotherm Cruise freezers have been designed to suit
the general dimensions normally used for this purpose.
The compressor should normally stand upright in the boat,
but will operate at an angle of heel up to 30° and for short
periods even more.
Avoid mounting the freezer close to a heat source, like gas
ovens and heaters. Also avoid a position allowing direct
sunshine on the freezer unit.
The mounting position should be dry and protected from
splashing water.
For easier mounting of the freezer, use the mounting rails
available as optional equipment, on the models not having
three side mounting frame.
The INOX types have fl ush mounting frame as standard.
The freezers shall be standing on the rubber feet and
locked in position by means of the mounting frame or
mounting rails. When no rails or frames are used the
cabinet must be well fastened into the surrounding con-
structions.
4.1 Ventilation
It is very important that the compressor/condenser unit is
well ventilated and that cold air can enter at the bottom,
pass behind the freezer and warm air can leave at the top
in the area where it is mounted. The natural fl ow of air from
below and upwards behind the freezer can be increased
by arranging ventilation openings at the rear.
Make sure there is a free area of 15 - 23 sq.in. below
and behind the refrigerator to allow ventilation air to pass
behind from below. See fi g.

4.2 Door front panel
The front panels on the doors can be replaced or addition-
al standard front panels in white, teak, mahogany or cherry
can be mounted on top of the standard panel.
The INOX models have doors in stainless steel and do not
have exchangeable door fronts.
Use a screwdriver or a knife as a lever and pull off the
lower door profi le. Unscrew the three screws holding the
door lock.
Mount the extra panel on top of the existing one, fasten the
door lock again and push in the lower door profi le.
See fi g.
4.3 Reverse the door hinge
The doors on the freezers are as standard mounted with
the hinges to the right hand side.
The door can be hinged to the left by means of changing
position of the upper and lower hinge fi ttings.
The door lock must also be moved to the other side.
See fi g. above.
The upper hinge pin is threaded into the top part above the
door, unscrew the top part to take off the door and move
the pin to the other side.
Or both the upper and lower hinge fi ttings are screwed into
the cabinet and have to be taken off and mounted on the
other side instead. The lower door support is also moved
to the other side.
CR INOX can also be re-hinged as described above. The
door locking is placed in the middle and does not need to
be re-positioned.
CR 90 Freezer INOX has left or right doors with side
mounted door locks and cannot be changed.
