Fault Finding; Technical Data - Indel isotherm Compact Classic Einbau- Und Bedienungsanleitung

Fault fi nding
Fault
Nothing happens when switched
on.
Compressor makes only short
start attempts when switched on.
Compressor runs but no
refrigeration generated.
Compressor runs long time but
not cold enough.
Compressor runs too long
time, too cold in refrigeration
compartment.
Fuse blows.
If a complicated fault does occur, such as those requiring specialist assistance (marked*), please contact Indel Marine S.r.l.
IT-61019 S. Agata Feltria (PU), Italy or your local marine distributor for advice.
Safety
Never open the refrigerant circuit, except by the quick couplings, they are of self sealing type and designed for this purpose.
Make sure the compressor ventilation is not blocked.
If a battery charger is mounted, it must be connected to the battery, never direct to the refrigeration unit.
When connected to shore power, ensure that the mains power supply system is equipped with an automatic earth leak switch,
"ground fault circuit interrupt"
When the refrigeration unit is to be disposed, this must be done by certifi ed refrigeration specialist for correct re-cycling of
electric and electronic components in according to EU directive 2002/96/EC (WEEE) and care-taking of the refrigerant.

Possible cause
Wrong polarity.
No power supply.
Battery in poor condition,
Voltage drop due to thin cables.
Faulty thermostat.
Bad power supply, too low voltage or voltage
drop at start attempts.
Discharged batteries.
Faulty electronic unit.
Loss of refrigerant. Quick couplings not
tightened enough.
Leakage in pipes or evaporator.
Bad compressor ventilation, and/or weak
insulation.
Thermostat sensor end not in mechanical
contact with evaporator.
Faulty thermostat not switching off.
Wrong fuse size.
Faulty electronic unit.

Action
Place + and − connections correctly.
Is main power switched on?
Check fuse.
Inspect charging circuit.
Check voltage drop.
Replace cables if required.
Bridge C and T on electronic unit. If compressor starts,
thermostat is faulty.
Check cables and connectors, possible verdigris.
Charge batteries by engine running or by battery
charger.
Exchange electronic unit.
Inspect and tighten. Contact refrigeration specialist to
check refrigerant. *
Contact refrigeration specialist for check-up. *
Improve ventilation, and/or refrigeration compartment
insulation.
Check sensor end mounting, re-fi t.
Replace thermostat.
Check fuse 15A-12V, 7.5A-24V
Exchange electronic unit.
