ALARM SIGNALS

CODE REASON
"HA" High temperature alarm
The temperature inside the cabinet has exceeded
the set alarm temperature. The alarm can be
instigated by sudden icing of the evaporator.
Initiate manual defrosting (see instructions on
page 4). Ensure the cabinet has not been loaded
with warm product. Check that a door has not
been left open. Check that product is not blocking
air circulation within the cabinet.
"LA" Low temperature alarm
The temperature inside the cabinet has fallen
below the set value. Ensure that the products put
into the cabinet are not too cold.
The temperature alarm will reset automatically
after the interior of the cabinet returns to set
temperature range. If this does not happen,
move the product to another cabinet and
contact your service provider.
"dA" Door open alarm
Only in models equipped with the door switch.
Close the door carefully and the alarm will reset
automatically.
"cSd" Condenser alarm
The condenser/fi lter needs to be cleaned.
Switch cabinet to standby mode, remove cover
and clean the fi lter by washing and or using a
soft brush and vacuum cleaner remove dirt and
debris from the condenser face. Check also that
air circulation to the condenser is not blocked or
that the ambient temperature is not too high. If
the alarm still does not stop, remove product to
another cabinet and contact your service provider.
