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 extremely simple to install. They will operate at a

continuous angle-of-heel of up to 30° in all directions, 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 levels 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 fridge

when leaving the boat for any length of time.

Operation

Temperature setting

The box is ﬁ tted with a manually operated, inﬁ nitely-variable thermostat. This is turned clockwise to reduce

temperature and anti-clockwise to both increase temperature and activate the on-off switch at the end position.

The thermostat knob is placed outside the box and allow setting within normal refrigeration temperatures between

+8°C and -14°C. A separate on-off switch is placed besides the thermostat knob.

Defrosting

Defrosting shall be made when the frost layer is more than 4 mm thick. Set the thermostat in OFF position

alternatively switch off by means of the switch. 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.

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 high efﬁ ciency and an outstanding life-time. The

build-in 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. Use a soft

brush and no hard objects.

Keep clean inside 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.

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 Cut-out Cut-in

12 V 10.1 V 11.4 V

24 V 22.3 V 23.7 V

Safety instructions

When connected to shore power, ensure that the power supply system is equipped with an automatic earth leak

switch. Danger!

Never tough bare electrical wiring connected to the mains supply. Danger!

Never connect battery charger direct to the refrigeration system. A battery charger be connected to the must

battery.

In addition to acid, a newly-charged battery contains explosive gas. Danger!

Never cover up the ventilation systems 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.

Installation instructions

Mount the box carefully and safe. It is important that the compressor and the condenser are well ventilated and

that cold air can enter and warm air can leave the space around the box. (Warm air is leaving upwards).

Do not install the box close to warm areas as the stove, heater or the engine.

The box is equipped with locking pins to ﬁ t brackets in the bottom.

The boxes shall be installed horizontally in the boat.

Electrical connections

When connecting the box electrically, it is important that following points are considered:

* Always use cables of sufﬁ cient area. The area in the following table should be regarded

as a minimum.

Cable area mm² Max cable length in metres, 12 V Max cable length in metres, 24 V

2.5

* Always connect the box directly to the battery or to the battery main switch. Do not connect it via the

boats own control panel or other diversions as this can cause a voltage drop in the power supply. The

box has a built-in 16A fuse mounted on the control panel.

* Connect the red cable to the positive (+) terminal and the black to the negative (-) terminal. Use the tab

type terminal included in the delivery, for connection to the power supply cable on the box.

* Do not connect the box direct to a battery charger. The battery charger must be connected

to the battery.

Fault Possible cause Action

Box not cold.

Compressor starts

but does not cool

the box.

Compressor will not start. Check that power is present at electronic unit.

Check fuse.

Reversed polarity?

Check all connections and cables.

Bridge the thermostat. See wiring diagram.

If the compressor starts this indicates a faulty

thermostat.

If the compressor does not start this indicates a

fault in the electronic unit or the compressor.

Contact an authorized service agent.
