8. Press RELEASE to automate the chiller start/stop value on the Status01 screen to enable
the chiller to start. The initial factory setting of this value is overridden to stop in order to

Manual Operation of the Guide Vanes
Manual operation of the guide vanes is helpful to establish a steady motor current for
calibration of the motor amps value.
In order to manually operate the guide vanes, it is necessary to override the TARGET GUIDE
VANE POSITION value which is accessed on the Status01 screen. Manual control is indicated
by the word ‘‘SUPVSR!’’ flashing after the target value position. Manual control is also indicated
on the default screen on the run status line.
1. Access the Status01 screen and look at the target guide vane position ( Figure 18 ). If the
compressor is off, the value will read zero.
2. Move the highlight bar to the TARGET GUIDE VANE POSITION line and press the
SELECT softkey.
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.
