WATER PIPING SYSTEM
As with any water system, it is important that the system is clean
As with any water system care should he taken to maintain a
clean system The installing contractor should remove weld
scale, rust and contamination during the fabrication of the piping
system We recommend the use of an alkaline ush of the piping
system prior to start-up
Necessary Components
All items depicted in gure 1 and 2 on page 11, other than
the modules themselves, are provided by others as optional
accessories and must he installed with the hydronics system
Several of these key components for the chilled water systems
are: water pump, strainer, isolation valves, ow switch,
temperature sensor wells, and pressure taps
Pressure Taps
The installer must provide access ports for connecting ow
switches (differential pressure or paddle style) for the chilled
water system (see page 11 – Water Piping Congurations)
Temperature Sensor Wells
Two temperature sensors and wells are provided with each
ClimaCool chiller system (chilled water inlet and chilled water
outlet) The installing contractor must install these temperature
sensor wells as shown in gures 1 and 2 on page 11
Strainers - (Minimum 60 Mesh Screen Required)
ClimaCool chillers employ brazed plate heat exchangers which
are extremely sensitive to debris Therefore it is mandatory that
the chilled water system include a strainer with a minimum of 60
mesh screen for proper ltration The strainers must be installed
as shown in Water Piping Congurations (see page 11)
Isolation Valves
It is recommended that water isolation valves are provided for
proper isolation and maintenance of the ClimaCool chiller, water
pumps, and strainer (see page 11 - Water Piping Congurations)
Flow Switch
It is mandatory that a ow switch (or differential pressure
switch) is installed in the chilled water circuit This ow switch
is supplied by others and is shown on page 11 - Water Piping
