Evaporator Piping - Trane AquaStream 2 CGWN Series Installation Operation & Maintenance

CG-SVX06F-GB
Installation

Evaporator piping

Evaporator water connections are
grooved. Thoroughly flush all water
piping to the CGWN or CCUN
units before making the final piping
connections to the unit. Components
and layout will vary slightly,
depending on the location of
connections and the water source.
CAUTION Equipment Damage!
If using an acidic commercial
flushing solution, construct a
temporary bypass around the unit
to prevent damage to internal
components of the evaporator.
CAUTION Proper Water Treatment!
The use of untreated or improperly
treated water in a chiller may result
in scaling, erosion, corrosion, algae
or slime. It is recommended that
the services of a qualified water
treatment specialist be engaged to
determine what water treatment, if
any, is required. Trane assumes no
responsibility for equipment failures
which result from untreated or
improperly treated water, or saline
or brackish water.
Drainage
Locate the unit near a large capacity
drain for water vessel draindown
during shutdown or repair. Water
piping is provided with drain
connections. Refer to "Water
Piping." All local and national codes
apply.
Piping
A vent is provided on the top of
the evaporator at the return end.
Be sure to provide additional vents
at high points in the piping to bleed
air from the chilled water system.
Install necessary pressure gauges
to monitor the entering and leaving
chilled water pressures.
