Page 24

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.
