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(gure
2.5A) 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.
2.7 ELECTRICAL CONNECTION
A. STANDARD MODELS
1. All electrical wiring must comply with local codes and the
National Electric Code.
2. Electrical power supply requirements for standard units
areidentiedontheequipmentdatatag.Determinethat
theplant’svoltagesupplyisthesameastheunit’svoltage
requirements, taking into account the SSCR Rating.
3. A customer supplied, four conductor cable is required for
connection to a customer supplied fused disconnecting
means. The fused disconnecting means shall be sized and
installedaccordingtotheunit’spowersupplyrequirements
and local electrical codes. (Some custom units may include

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
