Charge refrigerant
The P&I diagram states the charge for each specific chiller. Start out by charging 75% of the
specified R717 charge.
After start-up carefully charge more R717 until the suction superheat is between 0.5 and 3°K.
Check the liquid level in the evaporator. Droplets should come out of the top of the plates.
The plates should not be completely covered by liquid.
Note: The liquid level must never be visible in the inspection glass.
Power supply
Turn on power.
Control system
Check the UniSAB III control system settings including calibration according to the UniSAB III
manual.
Motor
Check the direction of rotation of the compressor motor.
Coupling
Check alignment of coupling.
ComPACs are equipped with flange motors, and alignment is normally notnecessary.
