Climate Class The cabinet is designed to operate within a climate class 3 environment (25°C @ 60% relative
humidity).
Cabinet
Location The cabinet should not be left exposed to direct sunlight at any time as this may cause
distortion of plastic parts.
The cabinet must not be situated where it is affected by air-conditioning air outlets, ventilation
fans or air re-circulation fans, as this will compromise the airflow and product temperature in
the open cabinet zone.
There must be no air movement directly into the cabinet opening. Air movement will cause
failure of the air curtain over the product, resulting in excessive temperature rise. Detectable
air draft will adversely affect the cabinet operation. Maximum air movement across the cabinet
opening must not exceed 0.2 m/s.
Stabiliser Feet The cabinet is fitted with two front stabiliser feet which hold the cabinet in place once it is in
position. The stabiliser feet are lowered and raised by the stabiliser feet pedals. Ensure the
stabiliser feet are raised when moving the cabinet around. Once the cabinet is in position,
lower the two front stabiliser feet to firmly contact the ground.
IMPORTANT
Do not leave the cabinet exposed to direct sunlight as this may
cause distortion of the plastic cladding.
IMPORTANT
There must be no air movement directly into the cabinet opening.
Procedure 1: To lower and raise the stabiliser feet
1. Move the cabinet into position, and remove the front panel (see page 17) to access the stabiliser
feet pedals.
2. Push the stabiliser foot pedals towards the inside of the cabinet to release, then push down to
lower the stabiliser feet, and up to raise the feet
3. Refit the front panel (see page 17).

Ventilation Keep the ventilation slots in the front panel clear at all times. Never store cardboard cartons
or other objects in front or behind the cabinet.
Power Cord The cabinet has a flexible power cord fitted with a 3-pin plug, which exits the rear of the
cabinet. Pull the power cord around so that it’s not trapped before you position the cabinet.
Shelves
Adjusting the
Shelves
The cabinet is fitted with three different sized metal shelves. The two top shelves are height
and angle adjustable, and removable. The angled bottom shelf is not adjustable. The shelves
are different depths, with the top shelf being the shallowest and the bottom shelf the deepest.
The two top shelves are each held in place by two cantilevered shelf brackets which clip into
cut-outs in the cabinet back duct. Further 6mm interval height adjustments can be made by
separating the shelf bracket into two parts and re-slotting together using the alternative slots
(see image below).
CAUTION
To prevent over-heating and conserve energy, ensure air flows
freely all around the cabinet, including underneath and on top.

Faults and Alarms
The following table explains faults and alarms that the electronic controller may log and
display.
If a fault occurs, the fault - alarm indicator is lit on the controller faceplate, but no message is
displayed. Faults do not affect product temperature, and require no action from the shop
owner.
Alarms are logged and the alarm message is displayed on the controller faceplate. Alarms may
result in abnormal product temperature.
Some faults and alarms can be cleared by the shop owner, and others can only be cleared by
a service technician.
If the cabinet is connected to the power supply and has warm product, check the SCS Connect
Field App for active fault or alarm, and investigate. If the cabinet does not have an active fault
or alarm, check the app statistics to determine if and when the controller signalled a fault or
alarm.
Refer to the tables below for faults and alarm descriptions and possible causes and actions.
