Compressor motor controllers
Compressor motors as well as controls and accessories
require the use of starting equipment systems specifically
designed for 19 Series chillers. Refer to Application Data,
Starting Equipment publications or consult Carrier regard­
ing design information for selection of controllers.
Capacitors
Power factor considerations may indicate use of capaci­
tors Properly sized capacitors improve power factors as
illustrated in the Typical Power Factors curve
However, the P.F. of Carrier are so high that correc­
tion is usually not necessary.

NOTES:
Listed motor voltages are design voltages Motors are suitable
for use with supply voltages as noted, and will operate satis­
factorily at 10% below the minimum and at 10% above the
maximum supply voltage
