PROBLEM |
POSSIBLE CAUSE |
REMEDY |
|
Unit not running. No indication lights on controller.
|
No main power supply. Lamp failure.
|
Check that the main supply from premises to unit is switched on. If supply is from a circuit breaker, check that it has not tripped. Reset if required. If the supply is fuse protected, check that the fuse has not blown. Replace it if required. Replace lamp if it is required.
|
|
Unit still not running. Check mains supply ok.
|
Loss of supply from plug to container.
|
If container cable has a plug fitted and it is plugged into a socket, this socket may have a circuit breaker fitted. Check to ensure this has not tripped. If tripped, reset. Please ensure cable has not been severed.
|
|
Unit still not running. No indication lights on controller.
|
ON/OFF Switch for unit in OFF position.
|
Make sure the ON/OFF switch is in the ON position. If the indicator lights located in the controller are illuminated, wait up to six minutes for the unit to start up.
|
|
If there is still no supply to unit.
|
Circuit fuse (switches) in controller may have blown.

CALL AN ENGINEER. 24 Hour Technical Helpline 0800 028 4133.
|
|
Temperature indication is above set point by more than 2oC.
|
Unit is in defrost mode, or just after defrost.
|
If the unit is in defrost mode, the fan and compressor will be idle. Please note the temperature shown in defrost mode is the temperature across the evaporator coil, not the temperature of the product. Therefore a unit in defrost will normally show high temperature readings. Wait a further 60 minutes to allow for normal operation.
|
|
Temperature monitor is above set point, but unit is not in defrost mode.
|
Evaporator coil is iced up.
|
Check inside the container to see if the evaporator coil is iced up. If so, the unit will require extra defrosting. Switch to manual defrost by pressing and holding the def key on the controller display. Note: long door openings will cause excessive ice build up.
|
|
Unit unable to achieve set temperature.
|
Condenser coil blocked.
|
Check to ensure the condenser coil (air intake) at the machinery end of the container is not blocked by dirt, plastic bags, paper or other debris. Any blockage should be removed. If the coil is blocked by dirt, it should be thoroughly washed and cleaned, taking care not to damage the aluminium fins. Squashed fins will reduce the efficiency of the unit and can lead to high pressure trips.
|
|
Unit unable to keep set point temperature after all previous checks have been carried out.
|
Mechanical or electrical problem, which requires the attention of an engineer.
|
Do not open the doors as the temperature will rise further. Contact the technical helpline. Note: prior to calling an engineer, please check the read out on the controller display, if any, and give this information to the service center - 0800 028 4133
