5 Technical data
Voltage
12 or 24 volt DC
Power consumption when compressor is running:
CR 63 F INOX:5.0 A at 12 V (half at 24 V)
CR 65F & CR 65F INOX: 5.0 A at 12 V (half at 24 V)
CR 90 F & CR 90 F INOX: 5.0 A at 12 V (half at 24 V)
DR 55 F INOX: 5.0 A at 12 V (half at 24 V)
Average consumption:
CR 63 F INOX: 1.5 A at 12 V (half at 24 V)
CR 65 F &: CR 65 F INOX: 1.5 A at 12 V (half at 24 V)
CR 90 F & CR 90 F INOX: 1.9 A at 12 V (half at 24 V)
DR 55 F INOX: 1.5 A at 12 V (half at 24 V)
Average consumption measured at -16°C/3°F in the freezer and 22°C/72°F ambient temperature.
The average consumption is much dependent on the way the fridge is used and how well the ventilation
is working.
Compressor:
Danfoss BD35F
Refrigerant:
R134a, fi lling amount is printed on the sticker inside the fridge.
Fuse:
15 A for12 volt or 7,5 A for 24 volt respectively.
Isotherm refrigerators and freezers fulfi l valid EMC directives and are CE-marked.
6 Trouble shooting
Fault
Possible cause
Action
Freezer not cold, compressor
will not start.
No power supply.
Battery in poor condition.
Faulty thermostat.
Faulty electronic unit.
Check that power is present at electronic unit.
Check fuse.
Check polarity on connectors and cables.
Bridge the thermostat over T-C, see wiring diagram. If
compressor starts, this indicates a faulty thermostat. If
the compressor does not start, this indicates a faulty
electronic unit or compressor.
Contact an authorized service agent.
A possible leak in the cooling system, contact an au-
thorized service agent.
Compressor makes only short
start attempts.
Bad power supply, too low voltage or
voltage drop at start attempts.
Discharged batteries.
Check cables, terminals and other connections, pos-
sible verdigris or corrosion, Clean.
Charge batteries, run the engine or connect a battery
charger. Voltage must be kept above 11.0 V at start
attempts.
Compressor runs but no refrig-
eration generated.
Loss of refrigerant. Leakage in pipes or
evaporator.
Pipes blocked.
Pressure and leak test. Check for pipe damages. Re-
pair possible leak, evacuate and re-fi ll refrigerant. (All
this to be made by refrigeration specialist).
Compressor runs long time but
not generating enough cold.
Bad ventilation. Condenser too warm.
Cooling fan not working
Too much frost on evaporator.
Door not closing well.
Condenser blocked by dust.
Improve ventilation for compressor.
Re-place fan.
Defrost.
Check/adjust door position and door seal.
Clean condenser.
Fuse blows.
Wrong fuse size.
Faulty electronic unit.
Check fuse, 15 A-12 V / 7,5 A-24 V
Exchange electronic unit.
If a complicated fault does occur, such as requiring specialist assistance, please contact Indel Marine USA or your local
marine distributor for advice.
