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
Aspect XL must be indoors and 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 Aspect
XL. For the final connection to the Herschel Aspect XL, 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 or Table 2.
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:
The Herschel Aspect XL must be located in a position to allow proper and efficient use but one that ensures hot
parts are not touched accidentally. The recommended installation height of the Aspect XL is 2.3m to 2.5m (90”-
98”) from the floor and under no circumstances is it to be installed at less than 1.8m from the floor. In all cases
it should be installed at a height where it cannot be touched in operation. Consideration should be given to any
temporary or occasional additions such as stages or platforms, and the height should be adjusted accordingly.
The Herschel Aspect XL should be firmly and permanently attached to the wall using the bracket supplied, with
the heaters angled down at 60° from vertical (see diagram 1). The bracket allows the heater to be mounted
between 50° and 70° from vertical and should not be mounted outside these parameters. The Herschel Aspect
XL is designed to be mounted horizontally on a wall. DO NOT MOUNT POINTING VERTICALLY
DOWNWARDS. The heater is not designed for ceiling mounting.
In areas with air movement/wind the directional Far Infrared spread may reduce by 1/3 to 1/2. In these areas
we recommend mounting at the lowest recommended height (see diagram 1) and proportionally increasing the
number of heaters.
CAUTION:
Ensure mains power is OFF before commencing installation.
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 Aspect XL 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 Herschel XL 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.
