W. Tombling FEZ200 User manual

Mounting and operating instructions
General instructions
Please read these instructions carefully before
installation and use, and keep them for future
reference.
Application area
The FEZ200 has two heating panels and is
designed for mounting heights of between 3 and 10
metres.
FEZ200 can be used for total or supplementary
heating of whole premises, and also spot or zone
heating in parts of premises.
Operating conditions
The maximum surrounding temperature must not
exceed +30 °C.
Do not install where explosive vapours may be
present, as defined in BS 5345. Or in environments
where there is an increased risk of fire.
FEZ200 are protected to IP44, and are intended for
indoor use only.
Mounting
The FEZ200 can be mounted on the ceiling,
armature rails, or wire, or suspended from the
ceiling by means of rods or chains.
The units are intended for permanent installation
and should always be mounted horizontally.
In rooms which are frequently used, the heater
should be mounted 1.5 to 2 metres above head
height, see Fig. 2.
The distance between the heaters should not be
more than the height between the heater and floor,
i.e. "a" should be less than "H", see Fig. 2.
For minimum safety distances, see Fig. 3.
Mounting brackets are included and can be found
inside the connection box.
1) Determine the position of the heater on the
ceiling.
2) Bend the "legs" of the brackets (fig 1.1) to
approximately 90° (fig 1.2).
3) Mount the brackets with an internal distance
according to dimensional drawing on page 2, on
the ceiling or on a wire (fig 1.3).
When the heater is mounted on a wire put the
bracket on top of wire, and use clips to prevent the
heater from sliding.
Mount the heater according to fig 1.4, making sure
that the screws are tight.
Electrical installation
EZ200 heaters are designed for fixed installation.
The heater(s) should only be wired by a competent
person and in accordance with the current edition of
the IEE Wiring Regulations (BS 7671:
Requirements for Electrical Installations) and any
applicable statutory regulations.
The appliance should be preceded by a double
pole isolating switch preferably with an indicator
light.
The FEZ200 is approved for serial connection.
Connection is made via the block terminals (16
mm²) which are located at the end of the heater.
There are two holes for cable glands on the top of
the connection box. The cable glands used must
guarantee the protection class requirements.
Installations protected by a Residual Current
Device (RCD)
If the installation is protected by means of a
residual current device (RCD) which trips when the
heater is connected, this may be due to a build up
of moisture in the heating element.
This is easily rectified by connecting the heater
without a RCD so that the elements dry out. The
drying time can vary from a few hours to a few
days.
As a preventive measure in damp environments the
heater should be run occasionally during the
summer months.
To prevent nuisance tripping of RCD’s in multi-
heater installations, the heaters should be divided
over several circuits, each with its own RCD.
Maintenance
The heaters have no moving parts and regular
maintenance is not required.
There might be a rattling noise the first few weeks
of use while the surfaces of the panels are settling,
this is normal.
If the heater is used in rooms where aerosols,
lacquers, solvents or similar are present, the
aluminium panels may discolour. The output of the
heater is not affected.
Important safety notices
Do not touch the heater while it is operating, the
surfaces are hot!
The heater must not he covered, as this will result
in a risk of fire!

Installation notes
FEZ200 heaters can be installed singularly, using a suitably rated double pole isolator.
However they are usually installed several at a time, in which case they are controlled using a
contactor, see the above diagram.
The cabling, contactor, and isolator must be rated to carry the full current of all the heaters. Isolation
and over current protection are required but have been omitted from the above diagram for clarity.
If a three phase supply is available the heaters should be connected between the phases and
neutral to form as balanced a load as possible.
The contactor can be controlled via a manual switch, thermostat, time switch, or a combination of all
three.
Compact enclosed isolators should be derated to allow for the effects of self heating.
FEZ200 heaters are a resistive load with low in rush currents, to prevent nuisance tripping we
recommend type C MCB's.
