Mandatory
Specifications
for
total
loss
cooling systems
CAUTION
If
clear
(i.e.
transparent)
tUbing
is
exposed
to
sunlight,
algal
growth
can
develop,
which
can
restrict
coolant
flow.
It
is
MANDATORY
that
clear
tUbing
is
not
used
in
any
part
of
the
cooling
system.
OIPT
recommends
the
use
of
either
black
or
dark
green
tubing.
CAUTION
It
is
the
customer's
responsibility
not
to
exceed
a pressure
of
5
bar,
or
other
limit
that
has
been
set
for
the
system.
Exceeding
this
safe
pressure
may
cause
irreparable
damage
to
system
components.
If
total
loss
cooling
with
municipal
water
(drinking
quality
water)
is
used in
the
system
or
in
the
pumps,
the
water
quality
must
meet
the
following
specifications.
Note
that
increased
maintenance
will
be
required
if
this
water
is
used directly
in
the
system
as
well
as
in
the
pumps.
The
water
must be
kept
warm
enough
to
prevent
condensation
on
chamber surfaces and
outside system components. This applies
to
those parts
of
the
system inside
the
clean
room
and those parts in a service area. Condensation can
damage
components such
as
RF
power
supplies,
ferrofluidic
seals and
automatch
units.
Any
damage
so
caused
cannot
be covered by
the
system
warranty.

NOTES:
a)
The
combined
Circuit Breaker MUST break all phases
if
anyone
phase
exceeds
the
set
current
limit.
b) The
trip
rating
of
the
Circuit Breaker depends
on
the
system
type
and
the
supply
voltage
to
the
system.
c)
The current-carrying capacity
of
the
cables
between
the
Circuit Breakers
and
the
system must be
greater
than
the
trip
rating
of
the
Circuit Breaker.
For example,
if
a 32A Circuit Breaker
is
fitted
then
a cable having
conductors
of
a
minimum
rating
of
40A (32A x 125%)
is
required. The
conductors
will
have a
minimum

Earth
connection
To
meet
international
standards
for
RF
interference,
our
systems are
fitted
with
filtration
on
the
mains supply inputs.
As
a result,
there
is
significant
leakage
to
earth
(ground)
from
the
mains supply.
WARNING
IT IS ESSENTIAL THAT
AN
EARTH CONNECTION IS
MADE
BEFORE
CONNECTING THE
SUPPLY.
International
standard IEC950, section 5.2, requires
that
a label
is
attached
at
the
point
where
the
system
is
connected
to
the
factory
electricity supply:
either
to
the
safety isolation box,
or
to
the
transformer,
or
to
the
electrical supply
outlet
socket. This label must contain
