CAUTION
The equipment must only be used with a protective earth power socket. The earth contact provides protection to
the user and the equipment. If you do not have a protective earth power socket, or you are unsure as to whether
you have a protective earth power socket,
do not
connect the equipment. In such cases you should consult your
workplace administrator or electrical maintenance staff to determine if a protective earth power socket is available.
A surge protected power outlet is strongly recommended as it provides some protection for the equipment
in areas of poor electrical quality as well as providing some protection against lightning strikes. The
equipment should be operated on a good, reliable supply of power at all times.
Note: The Immersion Heater Circulator should not be operated on the same electrical circuit as other high voltage
household appliances such as fridges, clothes dryers, washing machines or other continuous operation high voltage
devices. These types of devices can create power fluctuations that are undesirable for electrically sensitive
equipment. Consult your workplace administrator or electrical maintenance staff if you are unsure.
