Water Treatment
NOTICE
Proper Water Treatment!
The use of untreated or improperly treated water could
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.
Using untreated or improperly treated water in these units may
result in inefficient operation and possible heat exchanger
damage. Consult a qualified water treatment specialist to
determine if treatment is needed. See
water treatment requirements.
Evaporator and Water Piping
NOTICE
Water Born Debris!
To prevent evaporator or condenser damage, pipe
strainers must be installed in the water supplies to
protect components from waterborne debris. Trane is
not responsible for equipment-only-damage caused by
water born debris. Failure to install the shipped-loose
supplied Y-strainers or screens will void the warranty
on the brazed plate evaporator and condenser.
CG-SVX044F-EN
"Appendix B," p. 55 for
CICD chillers are equipped with brazed plate heat exchangers
made of stamped stainless steel plates, furnace brazed
together with copper based joints. Because of the small
complex geometry of the flow passages, it is imperative
customers take all precautions to ensure these evaporators
are not fouled by large particles or mineral deposits. Chillers
must have a factory provided, or field provided, 20-mesh
evaporator inlet wye strainer that must be field installed. The
screen may be removed for cleaning. Operation of chiller
without screen in place will void warranty. Chemical treatment
of the chilled water loop is required and must be performed by a
qualified water treatment specialist.
Chilled water inlets and outlets are grooved-type with the
locations provided in Dimension and Weights chapter. Under
full-load standard AHRI conditions, the chilled water
temperature change should be approximately 10°F, producing
a flow rate in the range of 2.4 gpm/ton. Minimum outlet water
is 42°F, with standard evaporator and without freeze inhibitor.
Minimum outlet water temperature is 40° F with high capacity
evaporator and without freeze inhibitor.
Chilled water piping must be in accordance with all local, state
and national codes.
