Locating the appliance
After unpacking, clean (cleaning directions supplied within this manual) and allow the appliance
to stand for 60 minutes before turning on.
Ensure the appliance is situated on a rm, level surface, away from both hot and cold air
sources, as this will aect its performance.
Place the appliance in a location so as not to exceed the maximum rated ambient
temperature.
The appliance produces warm air when operating normally and requires adequate
ventilation. The dimensions indicated are a minimum.
As the operating temperature has been pre-set no adjustments are required. Allow the
appliance to reach its normal operating temperature before loading with product.
Connect the appliance to a suitable power supply. Do not connect or disconnect the
appliance with wet hands. The appliance will turn on automatically displaying the actual
internal temperature of the appliance. If this does not happen and button 3 is‘pulsing’
press and hold button 3 for 3 seconds to turn on the appliance.

Other Information
Alarms/Warnings:
During operation the current temperature inside the appliance will be displayed. At certain times this will change to indicate a particular appliance
operation or fault. The indicators you may see are as follows:
The temperature alarms are either relative to the set point or an absolute value. This is controlled by the value of parameter ‘ATM’. Where the alarms
are relative the low alarm is the set point minus parameter ‘ALR’ and the high alarm is the set point plus‘AHR’. When the temperature has been
outside this value for the value of‘ATD’ the relevant indicator will be displayed.
hi - The internal temperature of the appliance is higher than described above. Ensure that the door is closed and that the air ow inside is not
obstructed by excesive or poor loading of product. The alarm will reset if the temperature falls to a normal level. If this does not happen please
contact your authorised dealer or Foster Service.
Lo - The internal temperature of the appliance is lower than described above. Check to ensure that the appliance has not been loaded with
product at a lower temperature than the normal appliance operating temperature. If this is not the case please call your authorised dealer or Foster
Service.
tA - Air probe has failed.. Call your authorised dealer or Foster Service to arrange for this to be replaced. During this time the appliance cannot
maintain an accurate temperature and all product should be removed and the appliance switched o.
tE - Evaporator probe has failed (not applicable to all models). Call your authorised dealer of Foster Service to arrange for this to be replaced.
PF - The mains power has been removed from the appliance for a period of time and has now been restored. This may have resulted in a rise in
appliance temperature. Caution should be taken when using products stored within to ascertain whether these products are suitable for use. Upon
restoration of the power supply the appliance will resume normal operation and the PF can be cancelled by pressing button 3 once.
HC - The condenser temperature is higher than it should be. If the appliance is being subjected to particularly high ambient temperatures steps

Condenser Cleaning
The condenser is a Stayclear condenser which does not require cleaning as regularly as a traditional nned condenser may. Care should be taken
when cleaning the condenser. Never use a wire brush, abrasive or corrosive materials to clean the condenser.
Door Gaskets
Door gaskets should be inspected periodically and cleaned where necessary with a warm damp cloth. Do not use aggressive cleaning materials on
the door gaskets.
Where door gaskets are damaged or not sealing correctly, they are required to be changed. These can be removed by pulling the old gasket from
it’s locating prole and pushing the new gasket into the same location. Where the gasket will not locate securely in the locating prole use a
rubber mallet to locate the gasket securely.
