4. When the common pipe grows to become 7x
greater in area than any of the other
interconnecting pipe, special rules will apply.
Consult the pipe manufacturer for these
details and/or special rules.
PIPING
After the chiller-heater has been
leveled properly, the piping for the
chilled/hot water and cooling water
circuits may be installed. Piping
arrangements should be made with care
so that there is no interference with
service access or panel removal. Piping
should be adequately supported and
braced independently of the unit so as to
avoid undue strain on the unit piping
connections.
Maximum
allowable
pressure in any fluid circuit is 113.8 PSI
(785 kPa)
.
Piping rules and conventions used
with Yazaki chiller-heaters are exactly
the same as used with any other type of
chiller; therefore, this installation manual
will not delve deeply into piping design.
CAUTION
1. Do not exceed 113.8 PSI
(785 kPa)
in
either the chilled/hot water or the
cooling water circuits of the Yazaki
chiller-heater.
2. Do not install any valves in expansion
pipe line.
Thermo-wells,
pressure
gauges,
Pete’s Plugs, etc. may be installed at the
inlet and/or outlet of each fluid circuit
connection to facilitate startup, future
service,
and
routine
maintenance.
Strainers in each circuit, particularly the
cooling water circuit, are recommended
as well. These should be placed before
the inlet connection of the chiller-heater.
