WATER PIPING SYSTEM
As with any water system, it is important that the system
is clean. Care should be 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 10, other than
the modules themselves, are provided by others as optional
accessories and must be installed with the hydronics system.
Several of these key components for both condenser and
chilled water systems are: water pump, strainer, isolation
valve, 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 both the
condenser and chilled water systems (see page 10 - Water
Piping Configurations).
Temperature Sensor Wells
Four temperature sensors and wells are provided with each
ClimaCool chiller system (chilled water inlet, chilled water
outlet, condenser water inlet, condenser water outlet). The
installing contractor must install these temperature sensor
wells as shown in figures 1 and 2 on page 10.
Strainers - (Minimum 60 Mesh Screen Required)
ClimaCool chillers employ brazed plate heat exchangers
which are extremely sensitive to debris.
Therefore, it is
mandatory that all condenser and chilled water systems
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 10).
Isolation Valves
It is recommended to provide water isolation valves for proper
isolation and maintenance of the chiller, pump, and strainer
(see page 10 - Water Piping Configurations).
Flow Switch - Required
It is mandatory that differential pressure flow switches are
installed in both the chilled and condenser water circuits.
These flow switches are shown on page 10 - Water Piping
Configurations.
