Test run
Set the switch to "NORMAL.AUTO". The
green light goes on immediately and the
yellow one shortly after indicating that the
compressor is running. Shortly after, a slight
hissing sound can be heard from the holding
plate, which after 15-30 minutes will show
signs of moisture or frost.
Start the engine. Within 2-10 minutes
(depending on condition of the batteries and
alternator) the yellow light will go out, the red
Fault finding
Fault
Nothing happens when
switched on. All lights off.
Green light on. Compressor
does not start.
Yellow light flashing. Low
voltage cut-out activated.
Compressor runs but no
refrigeration generated.
Compressor runs often but
temp. in box not cold enough.
Compressor never stops
running:
-Not sufficiently cold.
-Too cold.
-Temp. cannot be reduced
manually.
Compressor keeps running
when engine
is stopped.
Compressor will not run at full
speed and red light not on when
engine is running.
Radio interference when
running.
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.
one lights when the voltage comes above 13.2
volt. When the engine is stopped, the voltage
in the electrical system drops. Within a few
minutes, the yellow light comes on, the red
goes out. If the holding plate has reached its
full refrigeration capacity, however, the
compressor will stop instead. There is always
a 30 second delay before the electronic
monitoring system takes over.
Finally, check that the electrical wiring and
pipe work are safe and securely fastened.
Possible cause
No power supply.
Holding plate cold enough.
Temperature sensor not
connected. Fault in control unit.
Battery in poor condition.
Voltage drop due to thin cables
Loss of refrigerant. Connections
not tight enough.
Poor insulation. Fan not running
or too warm in compressor
compartment. Too much gas in
system. (Frost on pipe).
See above.
Temp. sensor faulty.
Temp. sensor touching box wall
or ice build-up.
Batteries in excellent condition,
or extra power source (solar
panel, wind generator, etc.)
Poor charging. Plus or minus
cables too thin. Connections
affected by verdigris, loose fuse.
System is suppressed and fulfils
present regulations. CE-marked.
Fault in control box.

Action
Is main power switched on?
Check fuse.
No action required. Check
cable. Replace*.
Inspect charging circuit.
Measure voltage drop when
running and replace cables if
required. Switch off, wait 5 sec.
Inspect and tighten. Contact
specialist to fill refrigerant*.
Re-insulate. Repair fan or
ventilate the space using air
hose kit. Call for refrigeration
specialist to check gas pressure
and adjust quantity*.
See above.
Renew.
Adjust sensor or defrost by
switching off system.
Normal operation. If temp.
becomes too cold switch to
"MAN.TEMP".
Check charging, cables etc. and
rectify. Clean and grease.
(Correct voltage > 13.4 V
measured at control unit with
compressor and engine
running).
Fit additional suppressor. (Min.
20A).
Renew 15 (7.5) A fuse or control
box*.
