IMPORTANT
MAINTENANCE
INSPECTION AND
CLEANING
Ensure the electrical supply cable is routed and restrained to prevent contact
with the external surfaces of the heater and is not positioned in the direct heat
beam.
When heater is close to a ceiling the reflectors must be rotated to avoid the
heat beam from directly overheating it. The reflector must point down at more
than 30° from the horizontal.
Vector I and RP when bracket mounted close to an end wall (minimum of
1.0m) should have the heat beam parallel to or angled away from the wall to
avoid overheating.
It is important that the user is instructed not to stack inflammable material in
the direct heat beam.
Since the Vector Heater contains no moving parts little maintenance is
required beyond cleaning and lamp replacement. It is however essential that
the heater is not operated with accumulation of dust or dirt on the lamp(s) or
reflector(s) as this can cause a build up of heat and eventual damage . For
this reason the heater must be inspected regularly, depending upon
conditions and at least at yearly intervals.
Before undertaking any maintenance work on the heater due attention must
be paid to the following,
1. Always disconnect the heater from the electricity supply before attempting
to work on or near it.
2. Always ensure a safe means of access using an access lower or properly
supported ladder.
3. Some types of quartz lamps run with an internal pressure in excess of
atmospheric and while construction is very strong there is a slight risk of
shattering. If it is necessary to examine a bare lamp whilst in operation
then a protective screen must be used.
4. Allow adequate time for the lamps and body casing to cool before
attempting to work on the heater.
1.
Check that all the lamps are functioning. If any thermostatic or time
controls are fitted ensure that the supply is 'on' before checking lamps.
Any failed lamps should be replaced (see lamp replacement). Remove
any accumulated dirt and check wiring and connections.
2.
Clean the lamp(s) and reflector(s) using a mild detergent solution and
soft cloth. Do not use any abrasive or caustic cleaners. Dry with a soft
cloth. Avoid touching either the quartz lamp sleeve or the aluminium
reflector with bare fingers. If they are accidentally touched remove any
finger prints using a soft cloth moistened with methylated spirit.
1.
Check that the lamp(s) are properly located in the spring retaining clips
and that they have not been disturbed by cleaning. The lamps should
be pushed fully back into the clips by applying light pressure on the end
caps only.
