Electrical connection
WARNING – THIS APPLIANCE MUST BE EARTHED
Verify that the electrical supply cable is sufficient for the rated loading.
Check that the incoming supply conforms to the rated supply.
The heater power circuit must be protected by a suitably rated over
current device.
The supply cables used must be suitable for hazardous area installation,
and for the temperature stated on the rating plate. They must be
connected to the heater using ATEX certified EEx d cable glands
designed for use with a female M20x1.5 parallel thread to BS ISO
262:1998.
Where the cable entry requires an adaptor, for size reduction, a suitable
ATEX certified EEx d adaptor must be used.
If the supply cable is housed in a conduit, to protect wiring, a suitable
ATEX certified EEx d adaptor must be used.
The incoming cables must be connected to the factory fitted heater
terminals provided. Do not alter any factory fitted wiring.
Before energising the heater for the first time, ensure that the insulation
resistance is at least 2 MΩ.
The heater is supplied with an earth stud, located inside the terminal box,
which must be connected to earth.
After connection check the continuity of earth connections.

Installation
The installation should be carried out by a suitably qualified electrician/
engineer in accordance with applicable standards.
All electrical tests must be carried out in a safe area; not in the hazardous
area.
The installer must ensure that any special conditions for safe use, detailed
on the ATEX certification, are met.
To remove the terminal cover, use a 13mm socket spanner. When refitting
the cover, ensure that all the joint surfaces are clean and free of any
debris and are unmarked.
Check that the heater supplied is suitable for the installation in the specific
hazardous area (Zone 1 or Zone 2, gas group IIA, IIB, or IIC).
WARNING: The heater is NOT suitable for Zone 0 installations.
Verify that the temperature class marked on the heater’s rating plate is
suitable for the environment in which the heater is to be installed.
The heater must be installed using the supplied wall brackets prior to
use. Mark, drill and fit suitable wall plugs in to a sound wall as detailed in
Fig. 3 below. The heater can either be mounted in the horizontal or
vertical plane. A minimum height of 300mm floor and 100mm from vertical
wall must be maintained. The heater should not be connected until the

Operation
If the environment into which the heater is being installed contains a
hazardous gas, ensure the control enclosure is purged and free from
any potentially flammable gaseous mixture before energising the heater.
It is important that all start up and operating procedures that are specified
with any control panel feeding the heater are strictly followed.
Control equipment must be sited outside the hazardous environment or
comply and be ATEX approved to the appropriate standard.
Cleaning and User Maintenance
All maintenance operations should be in accordance with EN 60079-17
(Table 1) and BS EN 60079-14.
All existing site safety regulations must be followed at all times.
Ensure that before any maintenance is carried out, there are no hazardous
gases present.
The heater must be fully de-energized before any work is carried out.
The heater should be subject to a regular maintenance schedule with the
following actions as a minimum:
· Check that the heater surfaces are clean and free from any
deposits. The heater can be cleaned by wiping with a soft
damp cloth. Neither abrasive cleaning powders nor furniture
polish should be used.
· Check that the continuity and insulation resistance is a
minimum of 2 MΩ.
· The internal wiring shall be clean and dry, with no apparent
deterioration of the wiring insulation.
· All connections shall be tight, without signs of overheating.
· For heaters with multiple elements check the resistance
against the figures recorded at first installation to ensure no
individual element failure has occured.
· When refitting the terminal cover, ensure the mating surfaces
are in good order, and the screws are tightened to 12Nm.
(Note: Do not lubricate threads before tightening)
