RTUD Condenser Elevation Setting

Condenser elevation setting is a require input during
startup of an RTUD chiller, and is accessible in
TechView, on the Unit View Screen. Go to the Unit View/
Chiller Tab, select Condenser Elevation setting and enter
condenser elevation in appropriate units. Reference
Figure 10. The shipped default of this setting is 0 and it
represents the distance of the bottom of the condenser,
relative to the top of the evaporator. Use a positive value
for the condenser above the evaporator and a negative
value for the condenser below the evaporator. An
estimate to within +/- 91 cm is required.

Condenser elevation setting allows proper EXV
operation. Failure to properly set the elevation can result
in low pressure cutout trips, or low differential pressure
trips during startup or large load transients, as well as
poor EXV liquid level control during operation.
