NOTICE:
Scroll compressor is adopted in 380V water chiller and power reverse-phase & open phase
protection controllers are installed in the water chiller, so the water chiller shall be energized
for inspection before starting. If the green light of the phase sequence control in the electric
control box brightens, the phase sequence is correct. If the red light brightens, it means reverse
phase, and any two phases of the power line shall be exchanged with each other. If the yellow
light brightens, it means open phase and it is necessary to cut off the electricity for inspection.
If the reverse phase or open phase appears, the water chiller will automatically stop running
or starting.

• The difference between the power voltage and the standard voltage shall not exceed 10 percent of the
standard value.
• Rated current(RLA)=the current of the machine under the ARI or UL standard conditions
• Minimum circuit current(MCA)=maximum loadx1.25+sum of the extra load (to decide the diameter of
the wire)
