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 flush of the piping
system prior to start-up .
Necessary Components
All items depicted in figure 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, flow switch,
temperature sensor wells, and pressure taps .
Pressure Taps
The installer must provide access ports for connecting flow
switches (differential pressure or paddle style) for the chilled
water system (see page 11 – Water Piping Configurations) .
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 figures 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 filtration . The strainers must be installed
as shown in Water Piping Configurations (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 Configurations) .
Flow Switch
It is mandatory that a flow switch (or differential pressure
switch) is installed in the chilled water circuit . This flow switch
is supplied by others and is shown on page 11 - Water Piping
Configurations .
