SUPPLIES
When deciding upon the best location, consideration must be given to the
following requirements.
a. Avoid structures liable to vibration, e.g. crane gantries, which could
otherwise adversely affect lamp life.
b. The lamps are designed to operate within 5° of the horizontal plane. It is
very important to ensure that the heater is mounted horizontally, otherwise
the operating life of the lamp could be impaired.
c. Ensure appliance is mounted the correct way up so that it can be tilted
down but not up.
d. WARNING – THESE HEATERS ARE DESIGNED TO BE WALL
MOUNTED, BRACKET MOUNTED, OR SUSPENDED MOUNTED –
THEY MUST NOT BE CEILING MOUNTED. THEY MUST NOT BE
MOUNTED IN A ROOM CONTAINING A BATH OR SHOWER. DO NOT
MOUNT HEATERS CLOSER THAN 3.5 METRES FROM CURTAINS OR
SIMILAR SOFT FURNISHINGS.
Wiring to the heater must be installed in compliance with the requirement of
the IEE Regulations and any local or insurance regulations.
All heaters are suitable for use on 230-240V single phase supplies. The
Vector III model is supplied as a dual voltage unit and is suitable for use on
400-415V three phase supply.
Wiring between the heater and the spur outlet or isolation switch must be in a
heat resisting cable with a temperature rating of T150. Sufficient slack cable
must be left to allow for angular adjustment of the heater body.
An all-pole isolating switch with a minimum separation of 3mm in each pole
must be fitted adjacent to the heater to facilitate local isolation.
If miniature circuit breakers are to be used to avoid 'nuisance tripping' due to
the high in rush at switch on, a type 3MCB with a tripping coefficient of 7-10
times rated current should be used. Any other switching device should be
Tungsten lamp load rated.
The Vector III heater must be connected in accordance with the instructions
inside the terminal cover lid. When connecting to 400-415V three phase
supplies the links must be removed from the terminal block. When the heater
is on a 230-240V supply, the 'Danger 400-415V' notice should be removed
from the terminal cover.
Always ensure that the cable grip is tightened.
