2.6 WATER-COOLED CONDENSER
A. Connect the facility cooling tower or city water supply to the
“condenser water in” connection on the unit.
1. Requiredowratefromacitywatersourceis1.5gpmat
65°F per ton of rated capacity.
2. Requiredowrateforatowerwatersourceis3gpmat85°Fpertonofrated
capacity.
B. Connect the facility tower system return or drain to the “condenser
water out” connection on the unit.
1. Note:Followalllocalcodesifdumpingtotheplant’s
sanitary or other drain.
C. The pressure differential requirement between the condenser “water in” and the
condenser “water out” lines must be 30 psi.
D. The installation of a strainer in the condenser “water in”
line is recommended. This removes solids from the water
supply and serves to protect the water saver (regulator)
valve.
E. The water regulator valve is normally factory set for
properoperation.Wheneldadjustmentsarerequired,
turn the adjusting nut on the top of the valve counter
clockwise to raise the refrigerant pressure and clockwise
to lower the pressure. Adjustments should be made only
when the chiller is running at full load.

WARNING: Do not connect the unit to a voltage supply not equal to the unit’s voltage
requirements as specied on the unit’s data plate. Use of incorrect voltage will void the unit’s
warranty and cause a signicant hazard that may result in serious personal injury and unit
damage.
WARNING: Electric Shock Hazard. High Voltage is present in the electrical cabinet. Disconnect
power before servicing. Follow all facility lock-out tag-out procedures.
