3-3 Water Treatment Considerations
Water treatment is an integral part of the system. In some
locations, water may cause large deposits of scale, erosion, algae,
and/or corrosion.
The use of a poor quality water may result in inefficient operation,
heat exchanger damage, and pump seal damage. Consult a
qualified water treatment specialist to determine whether treatment
is needed.
AEC, Inc. offers a complete line of water treatment equipment.
Contact your AEC, Inc. sales representative for water testing and
treatment options.
3-4 Water-Cooled Chiller Condenser Connections
FSS Series Water-Cooled Chillers
FSS-W Series water-cooled circulators can use city water as a
cooling medium or make-up. Make sure that all external piping
and connections supplying and discharging water to and from the
condenser are full size.
You’ll make two (2) connections to the water cooled condenser:
• The condenser water supply, labeled CONDENSER WATER
IN , is located at the rear of the unit, and is the inlet for city
water or central chill water system.
Make sure that water is supplied at a maximum temperature
of 85°F (29°C) and a minimum pressure of 25 psi
(172.4 kPa/1.7 bars).
!
CAUTION
The water-regulating valve is set at the factory.
Only a qualified refrigeration technician should adjust it!
Normal R-22 refrigerant condensing pressure is 210 psi
(1,447.9 kPa/14.5 bars), with 85°F (27°C) water at 25-psi
(172.4 kPa/1.7 bars) entering condenser water pressure.
• Condenser water return, labeled CONDENSER WATER
OUT , is located at the rear of the unit, and is the outlet for
water after it has passed through the condenser.
