Isotherm built-in box
41 litres
General
Specially designed to operate in tough marine
environments, Isotherm fridge and freezer boxes are
outstanding in both performance and reliability. Fitted
with a fully hermetic, leak-free compressor, they offer
the lowest possible power consumption and noise
level. All models are easy to install. BI41 is used in
the fi rst hand as a refrigeration box, but can reach
temperatures down to -10°C/14°F. The box can stand
an angle of heel up to 30°, for a short time even
more. To ensure that your Isotherm box operates as
effi ciently as possible, please follow these general
guidelines:
*
Unnecessary opening of the lid will increase
power consumption.
*
Good ventilation of the compressor and
condenser unit will reduce power
consumption.
* The electrical system should be in good
condition. Inspect batteries and charging
level regularly. Always use a separate starter
battery for the engine. Follow carefully the
guidelines regarding electrical cable areas and
fuse placements.
* Keep the inside of the box clean and dry.
Keep the lid slightly open, to air the box when
leaving the boat for any length of time.
* Keep the drainage in the box closed during
normal operation, if such is mounted.
Operation
Temperature setting
The boxes are fi tted with a manually operated,
infi nitely-variable thermostat to operate the box within
refrigeration temperatures. This is turned clockwise
to reduce temperature and anti-clockwise to increase
temperature.
Turn the thermostat knob to the off-position, maximum
anti-clockwise, to stop the unit working.
The thermostat knob is placed inside the box.
Defrosting
Defrosting shall be made when the frost layer is more
than 3-4 mm thick. Turn off the unit with the thermostat
put into off-position. Store the foodstuff and the bottles
as cold as possible during the defrosting. Do not use
sharp metal objects to remove frost or ice. Do not re-
start until the box is completely defrosted and dried. Do
not forget to close the drainage if such is mounted,
Maintenance
The Isotherm boxes have a fully hermetic closed
cooling system and do not require any maintenance or
refi lling of refrigerant. The compressor is of domestic
type and has a very higheffi ciency and an outstanding
life-time. The box shall be left in the boat during the
winter. (If the temperature is below freezing point, the
compressor will not start).
The maintenance is reduced to periodically, not less
than a year, cleaning of the condenser from dust, on air
cooled units. Use a soft brush and no hard objects.
Keep the inside of the box. Use lukewarm water and
a mild cleaner for the inside. Put the lid, during not in
operation periods, in a slightly open ventilation position.

instructions.
Battery voltage sensor
To protect the batteries from becoming completely
discharged, a battery voltage sensor switches off the
compressor automatically at the following levels:

Safety instructions and environment
- When connected to shore power, ensure that the
power supply is equipped with an automatic earth
leak switch.
Danger!
- Never touch bare electric wiring connected to the
mains supply.
Danger!
- Never connect a battery charger direct to the
refrigeration system. A battery charger
must
be
connected to the battery.
- In addition to acid, a newly-charged battery contains
explosive gas.
Danger!
- Never open the refrigerant circuit except by the re-
operable quick couplings which are of self sealing
types and designed for this purpose.
- Never cover up the ventilation system for the
compressor unit.
- The refrigeration unit must be disposed by a
refrigeration specialist for correct recycling of
components and care taking of the refrigerant.
