CONTROL PANEL

Initial Operation
The cabinet is designed to operate at a fixed temperature of +80°C once it has warmed up.
A safety device is fitted which will switch off the cabinet if the operating temperature exceeds a safe working level.
Please adhere to the operating temperatures. If the machine does switch off due to an excessive temperature, call a
service engineer immediately.
Switch cabinet on by pressing the on/off switch, when the temperature has reached the desired operating level, load
the food into the cabinet.
Adjusting the Operating Temperature
The operating temperature is adjustable between +50° and +85°C if required. However the food should be kept at
+70°C and above to ensure safety. To adjust the operating temperature follow the procedure below:
- Press and hold the green enter button
- Use the red up and down arrows to adjust the temperature
- When you are happy with the temperature release the green enter button
If no further adjustments are made within 10 seconds, the desired operating temperature will be stored and display will
revert to the actual cabinet operating temperature.
NB: All machines are preset at the factory, however conditions on site will vary compared with test conditions
and it may be necessary to perform the above adjustments several times in order to obtain a perfect
temperature cycle.

ROUTINE MAINTENANCE

All maintenance should be carried out by a competent, qualified person. We recommend regular preventative
maintenance using a qualified service provider in order to get the best from your equipment.
CLEANING
If cabinet exterior is looked after correctly it will retain an "as new" finish for many years. Normal day to
Exterior:
day cleaning should be carried out with a soft cloth and soapy water. For a stainless steel finish, always wipe
cabinet in same direction as the grain. Whilst stainless steel is robust, the satin smooth finish can be spoilt by wiping
against the grain. Never use abrasive materials or cleaners, or chemical cleaners.
These can damage the surface and cause corrosion. Occasionally, the exterior surface should be polished with a good
stainless steel polish to protect it.
Interior
: Racking can be removed for easy cleaning (see Figure 2),
cabinet interior should be cleaned regularly with warm soapy water
and a soft cloth. Dry thoroughly afterwards and where possible remove
all racking and shelving to aid the process.
To remove racking and shelf supportd, follow this procedure:
First remove shelves, then supportd by gripping formly at the centre
and lifting slighlty. Turn shelf support towards cabinet interior by
pushing at the centre as you twist support through 90°. The shelf
support will be released. (Note: the supports are designed to be
anti-tilt and some resistance may be experienced at first. This will be
overcome with practice).
remove the racking by lifting up and over the nylon retaining blocks.
When all shelves have been removed,
