Operation
Cabinet Operation
If the cooler has been disconnected from the power supply for any reason,
allow about 10 minutes before switching it back on. This allows the
refrigeration system pressure to equalise before the system is restarted.
Before operating the cooler, ensure:
The cooler is positioned on a level surface.
The maximum operating temperature is no greater than 32°C.
There is adequate ventilation around the refrigeration system.
There is a gap of at least 50mm around the cabinet.
The plastic drain pin (included in the bag with the user manual) is placed
into the drain hole at the bottom of the cabinet (see image below). This
prevents objects from covering the drain hole.
The cabinet stabiliser foot is screwed firmly down to floor level (see
image below).
The cooler is allowed to stand for at least 30 minutes before connecting
to the power supply.
While the cooler is operating it is normal to hear gurgling sounds caused by
the flow of refrigerant when each cooling cycle ends.
Refrigeration
System
The evaporator fan (located inside the cabinet) should operate continuously
from the time the cabinet is plugged in. This may be verified by checking for
air movement inside the cabinet. The thermostat will click when the
refrigeration system cycles on and off.
Cabinet Light
The cabinet interior light is controlled by the light switch next to the
thermostat knob inside the cabinet (see Figure 4 on page 9). The fluorescent
light will require a period of time to stabilise following initial start up. See
page 10 for instructions on replacing the fluorescent lamp.
Loading
The cooler should be left running for 30 minutes to allow the cabinet to cool
down before loading with product. When loading the cabinet shelves with
product:
Allow air space around all the product for even cooling and efficient
operation of the cooler.
Do not exceed a maximum of 30 kg per shelf.
Do not allow products to overhang the front or rear of the shelves, as
this will affect air flow.
Do not obstruct air flow from the evaporator fan (inside the cabinet).
Do not block the drain hole inside the cabinet.
