damaged due to insufficient water levels or inappropriate temperatures being applied as a result of re-filling.
Adjusting the Mounting
Clamp
The Immersion Heater Circulator features an adjustable clamp that allows the unit to be mounted on water baths
and tanks with side walls varying from 1mm to 63mm wide. Before adjusting the clamp, ensure the equipment is
disconnected from the mains power supply and the element is cold. The adjustment is performed in 2 steps as
illustrated below. Step 1 – Turn the unit upside down and gently rest it on the lid on a non-scratch surface. Using a
phillips head screwdriver, loosen the 2 clamp screws as illustrated below with half a turn anti-clockwise. The clamp
bracket can now slide in and out to the required depth as required. Once the depth has been set, re-tighten the 2
clamp screws by gently tightening in a clockwise direction. Step 2 – Once the unit is placed on the bath, gently
tighten the thumb-screw by turning in a clockwise direction until the unit is secured to the bath.
Step 1 – Use a phillips head screwdriver to adjust the clamp depth
Step 2 – Use the thumb-screw to tighten against the bath
Connecting Power
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.
The mains power supply must be rated to match the power requirement as identified on the product identification
label on the rear panel. This is normally expressed in the format of Voltage Range and Frequency.
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.
IMPORTANT : Use of an incorrect power supply will void the product warranty. If you are unsure about the
rating of your power supply, consult your workplace administrator or electrical maintenance staff to
determine if your power supply is suitable for use with this product before connecting the power lead.
