CLW QUAD SERIES CHILLER INSTALLATION MANUAL
Field Wiring and Control Setup
Line Voltage
High Voltage Connections
Connect power wiring as shown in the line voltage wiring
schematic on page 13.
Low Voltage Operation
Thermostat/Controller (Aquastat)
A two-stage 24 VAC thermostat or liquid controller (field
supplied) must be used to turn the commercial chiller on
or off, and to switch it from cooling to heating if
necessary. Multiple chillers in the same bank must be
controlled from one thermostat/controller (must be
isolation relays for multiple unit applications).
Low Voltage Connections
Connect low voltage thermostat wiring as shown in the low
voltage wiring schematic on page 12. Connections shown
are for typical thermostat. Actual connections may vary
with specific device used.
NOTE: If a separate transformer is used to supply a Y1, Y2, or
B signal to the unit controls, isolation relays must be used.
CAUTION: Use only copper conductors for field
installed wiring. Terminals in the unit are not
designed for other types of conductors.
WARNING: All wiring must comply with local and
state codes. Disconnect the power supply before
beginning to wire to prevent electrical shock or
equipment damage.
