The incubator is internally protected by a fuse, which isolates the cabinet from the
electrical supply if excessive current is drawn. The fuse holder is located on the rear
of the cabinet. The instruments on the control panel will illuminate when the supply is
connected correctly and POWER switch is on.
2.3
General Precautions
A qualified electrician or other competent person must carry out
any electrical work required to install the incubator.
Do not place the incubator in direct sunlight or near a heat
source.
Make sure the incubator is not standing on its electrical supply
cable.
Before the incubator is switched on for the first time, it should
stand still for 2 hours after final positioning to allow the
refrigerant to settle.
Keep all ventilation grilles clear. Failure to do so may result in
component failure.
The refrigeration system gives off heat when operating. Always
ensure there is adequate ventilation around the incubator.
NEVER PLACE ANYTHING ON TOP OF THE INCUBATOR.
Before any cleaning or maintenance work is carried out, the
mains supply must be switched off and the plug removed from
the electrical socket.
