Before installing:
9Inspect the heater. Verify it is undamaged
after transport, and that there is no damage to the glass,
teflon plastic junction box or electric cable.
9Locate the heater nameplate tag which provides kW,
voltage, product identification number and certification.
9Check the sheath material to be sure it is compatible
with the intended bath solution on page 4. If you are even
slightly uncertain, contact us!
9Process tank is equipped with a low solution level
detection shut-down device.
9Confirm the line and heater voltage agree and the
cubicle is locked for heating capacity.
9If voltage or material is incorrect, do not
install or operate heater.

During installation:
9Installation must be done by a qualified electrician.
In a stationary electrical installation an omnipole
contact breaker must precede the heater.
9Confirm all power is disconnected and fuses have
been removed at the actual switching point.
9Heaters without supports have to be installed
vertically. The active part should be at least 20 mm
from the tank wall, bottom, or sludge accumulation.
Otherwise, overheating and/or heater damage can
be the consequence.
9Heaters should be installed for stationary service
(anchored) in a bath solution of 95° C max.
Min. level and max. level for bath solutions are
marked on the heaters.
While in service the solution level must be
maintained between these markings.
9For electrical heating, a level control must always be
installed. If not, overheating can occur at min. level,
which may be a fire hazard.
9In service, heaters should be protected from contact
with moving parts, anodes, cathodes, or any other
source of current.

Maintenance and control of immersion heater in service
9Maintain the solution level between the two level
Marks (see page 5).
9Clean heaters regularly and check function of level
control.
9Check heaters regularly for any sign of potential
failure, such as cracks (glass or teflon) or corrosion
(metal heater).
9When checking the element, the electricity supply to
the heater must be turned off at least 20 minutes
prior to exposing the element to air.
9The supply cord cannot be replaced. If the cord is
damaged the appliance should be scrapped
(flexible heaters).
9If the supply cord is damaged, it must be replaced
by manufacturer, its service agent or similarly
qualified person in order to avoid a hazard
(tubular heaters).

Attach the fastner
9Attach the fitting to the plate with both openings at the same direction (make
sure that you are using one of the openings on the same side as the hold-up
device and that the device side is pointing down.
Then insert the submersible cable through the opening and then rotate the fitting
180 degrees to lock the cable inside.
9Insert the submersible cable in one of the other openings on the other side of
the plate (make sure that the part of the cable are closer to the connection box as
the pictures shows) and place it on the bath edge.
9Be sure that the heating part of the heater is under the solution level before
Switch on the heater.

Cleaning of heaters:
9Turn off the heat electric supply for at least 20 min.
prior to exposing the element to air.
9A soft brush or gloved hands are recommended to
remove build-up from the element. Be cautious
while cleaning to avoid damage.
9Do not remove the over heat protection when cleaning the heater.
