* Consult Harry Taylor of Ashton Ltd.
Technical Department.
(r) Complete commissioning card and
provide operating instructions for the user,
high-light the fact that the manufacturer
recommends that in the interests of safety
and efficiency the heater is serviced on a
regular basis only by qualified and
competent persons.
The completed commissioning card must be
returned to Harry Taylor of Ashton Ltd.
Service Department immediately after the
satisfactory completion of commissioning,
failure to do so can invalidate any
subsequent warranty claim.
(s) Set all controls to the requirements of the
user.
4.3 Commissioning - air delivery
system
On free blowing applications the integrity of
the fastenings on the heater top and outlet
nozzles must be checked .
Final adjustment for the direction of the air
flow from the nozzle hoods should be made,
and the hoods should be secured in the
required position by drilling through the two
holes provided in the hood outer ring and
fastened in place using self tapping screws.
Caution
On ducted applications it is necessary that
the system is balanced in order to optimise
the efficiency of the heater and the air
distribution and delivery system Failure to
balance the system can result in fan motor
overloading and premature component
failure, it can also result in an inefficient
heating/ventilation system.
(a) Check that the amount of fan produced
air volume is in accordance with the heater
specification, if the volume is too great the
fan can be overloaded. Ensure that the
running current is as per that stated on the
heater data plate.
Alternatively, the static pressure should be
measured at the start of the ductwork to
confirm that it is within the permissible
tolerance.
(b) If the current drawn is greater than the
stated running current, in most probability
this will be caused by insufficient static
pressure within the ductwork, in which case
system resistance should be increased
through the introduction of a damper placed
as close to the start of the ductwork as
possible, thereby resulting in a reduction in
drawn current.
The damper should be adjusted until the
current is in accordance with that stated on
the data plate.
(c) If the current drawn is too low the duct
outlet grilles will require opening to reduce
static pressure and increase air volume, if
this is not the case overheat cut outs can be
caused.
The Fan Belts must be rechecked on
completion of commissioning ensuring
that the tension is correct and the pulleys
are in alignment
4.4 Commissioning - hand over
(a) Upon full and satisfactory completion of
commissioning, a record of commissioning
information (contact, date, etc) should be left
with the heater, a copy of which must also
be forwarded to Harry Taylor of Ashton Ltd.
Service Department.
(b) The commissioning engineer must
ensure that the user is familiar with the safe
and efficient use of the heater, detailing the
function of all controls, and main
components.
(c) The user should be made aware of the
following in particular
(i) Lighting, shutdown, and operational
information.
(ii) Safety features, data plate, and labelling.
(iii) The requirement for regular inspection -
especially if the heater is within a more
demanding environment - and the need for
regular servicing carried out by competent
and qualified persons.
