protected by a fuse or miniature circuit breaker suitable for the electrical rating of the unit and in accordance
with Table 1.
The supply to the heater must be switched separately using a switch appropriately rated for the load and
supply voltage. A switched fused spur may also be used on existing ring main circuits where the load current
is less than 13A. In both cases, the switch must be double pole (disconnecting both live and neutral
conductors) and form part of the fixed wiring in the installation in accordance with applicable wiring
regulations. The spur fuse should also be rated in accordance with the appropriate table. In either case the
switch used to operate the Herschel PULSAR must be readily accessible.
The cable used to connect to the existing wiring should be correctly rated solid core wiring cable. Please
note that the use of flexible appliance cable with stranded conductors for permanent wiring (except for the
final connection between a cable outlet and the fixed equipment) is prohibited by IEE wiring regulations.
Where applicable, these regulations preclude the use of a 13A plug and socket for powering the Herschel
PULSAR. For the final connection to the Herschel PULSAR, only the flexible cable and cable entry supplied
with the unit must be used. The cable must connect to the supply in a suitable enclosure or cable outlet
designed for that purpose. The cable outlet current carrying capacity must be greater than the
recommended fuse current rating given in Table 1.
If the flexible cable is taken through a wall for connection purposes, suitable conduit or mechanical
protection must be used through the wall to protect the cable from mechanical damage within the wall. The
mounting position of the unit must ensure that any mechanical damage to the flexible cable is unlikely. Any
exposed flexible cable is to hang down (not tied UP) and must have adequate clearance from the heater to
prevent scorching or damaging the cable.
Colour coding used in the supplied mains cable: BROWN wire is to be connected to LIVE (‘L’), the BLUE wire
to NEUTRAL (‘N’) and the GREEN/YELLOW wire to EARTH (‘E’).
MOUNTING POSITION:
CAUTION
:
•
Ensure mains power is OFF before commencing installation.
•
The supplied mains cable must not contact the top surface of the heater during operation.
•
Heater must not be located immediately below a socket outlet.
•
Joists, beams and rafters shall not be cut or notched to install the appliance.
•
Do not install the PULSAR into a ceiling recess, nor adjacent to a heater that has been ceiling-recessed.
•
The identification mark and model reference should be visible after installation.
•
The PULSAR must not be attached so as to face or be close to any combustible material (eg, wood or
PVC cladding, fascia or soffit).
•
The fixed wiring insulation coming into contact with parts with a temperature rise of greater than 50°C
must be protected, for example, by sleeving having an appropriate temperature rating.
