Two connections are made to each SSC Series unit:
Condenser Water In
The city or tower water supply inlet is located at the side or rear of
the chiller.
• Water pressure ≥25 psi (≥172.4 kPa/≥1.72 bars)
• Water temperature ≤85°F (≤29ºC)
Condenser Water Out
The return outlet, located at the chiller side or rear is connected to
a cooling tower inlet, a sewer or other approved discharge receiver.
• A water regulating valve is a standard feature in the condenser
water out line.
Caution!
The water regulating valve is set at the factory.
It must not be adjusted except by a qualified refrigeration technician.
3-10 Installing the Remote Air-Cooled Condenser
SSC Series models use the surrounding air to cool the remote
condenser. All models have variable speed fans and low ambient
controls to allow proper operation down to -20°F (-29ºC) outdoor
air temperature.
Install the remote air cooled condenser where there is:
• Greater than or equal to -20°F (-29ºC) air temperature.
• Free passage of air for condensing.
• Adequate structural support.
• Protection from strong winds and drifting snow.
• Provisions for removal of heated air from the area.
• No steam, hot air or fume exhausts drawn into the condenser
coils.
• Service accessibility.
