Chilled/hot water piping
Chilled/Hot Water Exchanger water connections are
grooved. Thoroughly flush all water piping to the unit
before making the final piping connections to the unit.
Components and layout will vary slightly, depending on
the location of connections and the water sources.

chilled-water system can also increase pressure drop and
consequently, reduce water flow. Proper water treatment
must be determined locally, depending on the type of
system and local water characteristics.
Neither salt nor brackish water is recommended for
use in Trane air-cooled unit. Use of either will lead to an
unpredictably shorter life cycle. Trane encourages the
employment of a reputable water treatment specialist,
familiar with local water conditions, to assist in this
determination and in the establishment of a proper water
treatment program.

Technical Data
If calcium chloride is used for water treatment, an
applicable corrosion inhibitor must also be used. Failure
to do so may result in damage to system components.
Do not use untreated or improperly treated water.
Equipment damage may occur.

7 = Stop valve located on the outlet connection: used to
measure the water pressure inlet or outlet of chilled/hot

8 = Strainer: avoid to get heat exchangers dirty. All
installation must be equipped with efficient strainer in
order that only clean water enters into exchanger. If
there is no strainer, reserve will be formulated by the
Trane technician at the start-up of the unit. The trainer
used must be able to stop all particles with a diameter
greater than 1 mm.
9 = Draining: used as the draining the plate heat
exchanger.
10 = Do not start the unit with low water volume or not
enough pressurized circuit.
Note: A pressure switch device to detect lack of water
is not included in the pump package. Installation of this
type of device is highly recommended to avoid sealing
damage due to operation of pump without enough
water.
