can be instigated by sudden icing of the evaporator. Initiate additional manual defrost.
See instructions on the previous page. Ensure the cabinet has not been loaded with warm
products. Check that a door has not been left open. Check that any product is not blocking air
circulation within the cabinet. The cabinet is meant to keep ready chilled products cold.
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 the
set temperature range. If this does not happen, move the products to another cabinet and
contact your service provider.

Freezer cabinets are supplied with a doorframe heater,
this is 'on' when the cabinets is shipped from our
factory. The vast majority of time this heater is not
required and it can be switched 'off' to reduce energy
consumption. When there is extremely high humidity
you may notice condensation on the doorframe in this
case switch the heater 'on' using the switch behind the
top cover.
Note!
Our energy consumption tests are made with the doorframe heater 'off' .
