SAFETY INSTRUCTIONS
This manual has safety information and instructions to help users eliminate or reduce the risk of accidents and injuries.
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.
Follow recommended precautions and safe operating instructions.
UNDERSTAND SIGNAL WORDS
A signal word , WARNING OR CAUTION is used with the safety-alert symbol. They give the level of risk for potential injury.
indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
indicates a potentially hazardous situation which, if not avoided may result in minor or moderate injury.
CAUTION used without the safety alert symbol indicates, a potentially hazardous situation which, if not avoided may result in property damage.
Read and follow all safety information and instructions.
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.Install 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 data plate is located on the back of the cabinet.
SPECIFICATIONS
A.Danfoss Compressor Data
1.Voltage 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).
