5. Oil reservoir temperature is above 140 F (60 C) or refrigerant temperature plus 50° F

(28° C).

6. Valves in the evaporator and condenser water circuits are open.

Note: If pumps are not automatic, make sure water is circulating properly.

7. Solid-state starter checks: The Power +15 and the Phase Correct LEDs must be lit before

the starter will energize. If the Power +15 LED is not on, incoming voltage is not present or

is incorrect. If the Phase Correct LED is not lit, rotate any 2 incoming phases to correct the

phasing.

8. Press RELEASE to automate the chiller start/stop value on the Status01 table to enable the

chiller to start. The initial factory setting of this value is overridden to stop in order to prevent

accidental start-up.

Do not permit water or brine that is warmer than 110 F (43 C) to flow through the
cooler or condenser. Refrigerant overpressure may discharge through the relief
devices and result in the loss of refrigerant charge.
