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 firm, level surface, away from both hot and cold air sources, as this will affect its performance.
Place the appliance in a location so as not to exceed the maximum rated ambient temperature. Areas where air is projected directly into the front of the appliance (for example from air conditioning units) should also be avoided.
The appliance produces warm air when operating normally and requires adequate ventilation. The dimensions indicated are a minimum.
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 (see controller operation for button identification).
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.

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 flow 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.
E1 – 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 off.
E2 – Evaporator probe has failed. Call your authorised dealer of Foster Service to arrange for this to be replaced.
E3 – The shelf temperature probe has failed. Call your authorised dealer or Foster Service to arrange for this to be replaced.
dEF – Defrost in progress. This is normal and your appliance will carry out a defrost periodically through each 24 hours. The contents of the appliance will be unaffected by this operation.
While in an alarm condition icon 1 will also be illuminated.
(Some indications are only visible periodically during specific appliance operations such as defrost or when activated through use of the appliance).
Probe Function
T1 – Controls the compressor on/off cycle based on the Set Point value located in the air return close to the fans.
T2 – Evaporator probe for defrost control.
T3 – The temperature displayed on the controller. The response is delayed to prevent the display of large changes in the temperature. Over time the displayed temperature will move to align with the T1 temperature subject to product load and appliance use. The probe is located in front of the air duct at the top left corner.

Probe Information
The probe is a type 10k NTC. The probes are identical in characteristics with the T1 and T2 identification markings and different colours being for ease of identification and not for functional reasons. Please refer to the image below for probe identification.

Evaporator Fan Motors
The evaporator fan motors will continue to operate during defrost. This is normal and is required for the successful completion of the defrost operation.
Defrost Indication
During defrost icon 4 will be illuminated. The controller display will be determined by the value set in parameter `DDM’.
To start a defrost manually press and hold button 3 for 5 seconds. This will turn off the appliance. Continue to hold down button 3 after the appliance has turned off. After a further 2 seconds the display will indicate a defrost has commenced (icon 4 illuminated) and the button can be released. While the defrost function is operating the display will be determined by the value set in parameter DDM.
The defrost function will operate until either the time set in parameter DTO or the temperature set in parameter DLI is reached. Where parameter TE is set to NO defrost will function on a time basis only. Upon completion of the defrost cycle the appliance will resume normal operation with the current temperature displayed.
Note – On this appliance it is normal for the evaporator fans to continue to operate during a defrost cycle.

Maintenance
Condenser Cleaning
The condenser is a Stayclear condenser which does not require cleaning as regularly as a traditional finned condenser may. Care should be taken when cleaning the condenser. Never use a wire brush, abrasive or corrosive materials to clean the condenser.
