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
"Appendix B," p. 53
for 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-SVX044B-EN
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.
