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
Benson
Environmental
Ltd
Service
Department
immediately
after the satisfactory
completion
of
commissioning,
failure to
do
so
can
invalidate
any
subsequent
,varranty
claim.
(u) 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 bonnet top
and
outlet nozzles
must
be checked.
If
any
final
adjustment
is necessary the fastenings
must
be secured
upon
completion.
Cauti
on
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 hea ting / ven tila tion system.
(a)
Check
that
the
amount
of
fan
produced
air
volume
is
in
accordance
with
the
heater
specification, if the
vo
lume
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
duchvork
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
''\lith
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.
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 Benson
Environmental
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
CD
Lighting,
shutdown,
and
operational
information.
(li) 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.
(d) Section C
'User
Instructions'
should
be
left
with
the
customer
upon
satisfactory
completion
of
the
commissioning
and
hand-over.
Note
After
approximately
100
hours
of
running,
the tension of the fan belts
must
be checked to
ensure
that
they are correct
and
that
they
have
not
stretched. See section 5.2 for further instructions.
