2.2Cabinet Operation
Before Operating
Before operating the cooler, ensure:
•the cooler is positioned on a level surface.
•that the maximum operating conditions are 40°C at 75% RH.
•there is adequate ventilation around the refrigeration unit.
•there is a gap of at least 35mm behind the cabinet.
•the rubber door stop is removed from the bottom lock bracket.
•both front stabiliser feet are screwed firmly down to floor level.
•both stand-off stops are fitted to the rear of the cabinet.
•the plastic drain pin is fitted in the drain hole in the cabinet liner
bottom.
•the cooler is allowed to stand for at least 30 minutes before
connecting to the power supply.
Connect the cabinet to the mains power supply and check operation
of the refrigeration unit and cabinet lighting.
Refrigeration Unit
The refrigeration unit evaporator and condenser fans should all
operate continuously from the time the cabinet is plugged in. This
may be verified by checking air movement inside the cabinet and out
of the top of the front kick panel.
Cabinet Lighting
The sign light and cabinet interior light will both go on when the
cabinet is plugged in, and will stay on permanently. The fluorescent
lights will require a period of time to stabilise following initial start up.
See pages 10-11 for instructions on replacing the fluorescent tubes.

efficient operation of the cooler.
•Do not exceed a maximum of 195 kg/m
2
•Leave an air space of at least 50mm above product on the top
shelf.
•Do not allow products to overhang the front or rear of the
shelves, as this will effect air flow.
The cooler should be
left running for 30
minutes before loading
with product.
Ensure the shelves are securely
fitted, using all four of the supplied
shelf clips on each shelf.

and 6 being the coldest. The normal temperature controller setting
is between 3 and 5.
•To make colder - turn the controller knob clockwise.
•To make warmer - turn the controller knob anti-clockwise.
