RECOGNIZE SAFETY INFORMATION

This is the safety-alert symbol. When you see this symbol in this manual, be alert to the potential for personal injury.

GENERAL INFORMATION

A. Before installing your Dometic refrigerator , refer to the

Tundra Installation Check List 3309081.0XX located in the envelope assembly furnished with your Tundra Refrigerator.

B. This refrigerator is designed for making ice and the

conservation of food and drinks only .

C. All materials exposed to contact with food comply with

EC directive 89/109.

D. Inst all appliance away from heat sources in a dry and

well-ventilated area. Avoid direct contact with water.

The Refrigerator is not waterproof.

E. This refrigerator complies with EC directive 89/336

governing radio suppression.

Note: The data plate bearing the model number , serial number, and technical data is located on the right-hand side, inside the refrigerator. An identical dat a plate is located on the back of the cabinet.

SPECIFICATIONS

Follow recommended precautions and safe operating instructions.

A. Danfoss Compressor Data

1. Volt age Operating Range 12 VDC systems: From 10.4 VDC to 17 VDC 24 VDC systems: From 22.8 VDC to 31.5 VDC

The electronic unit will calibrate automatically to the applied voltage. This means that if the battery voltage is less than 17 VDC, the electronic unit assumes that it is working in a 12 VDC System. If the voltage is higher than 17 VDC, the electronic unit assumes that it is working in a 24 VDC system. Consequently, the compressor does not run at power supply voltages between about 17 VDC and the desired battery protection cutout voltage (22.8 VDC) for 24 VDC systems.

2. Protection Systems The compressor protection system facilitates protection against compressor overload and start failure as well as destructive battery discharge. When an overload protection is activated, the compressor enters a cycle in which it makes start attempts at approximately 60 second intervals until successful start is achieved.

3. Overload Protections The compressor overload and start protection cuts off power to the compressor if the compressor speed drops below approximately 1,900 rpm, or if this motor speed is not reached during the start sequence. Possible reasons for overload protection activating could be too high refrigeration system pressures during operation or lack of pressure equalizing at start. The fan overload protection stops the compressor and the fan if the fan current exceeds 0.5 A (average) or 1 A (peak).

An overheating of the electronic unit heat sink will cause the compressor to stop. Restart will occur automatically when a normal temperature has been reached.

4. Voltage Protection If a voltage outside the operating range is applied to the electronic unit, the compressor does not start, or it stops if the voltage limit is exceeded during operation. The compressor will restart automatically approximately 1 minute after the supply voltage has reached the reset voltage within the range in question.

5. Battery Protection The electronic unit provides protection as follows:
