Connect Control Inputs 
Connect the control input wiring from the chilled and condenser water flow switches to the 
starter terminal strip. Wiring may also be specified for a spare safety switch, and a remote start/
stop contact can be wired to the starter terminal strip. Additional spare sensors and Carrier 
Comfort Network modules may be specified as well. These are wired to the machine control 
panel as indicated in Figure 22 and Figure 23.
Do not attempt to start compressor or oil pump (even for a rotation check) or 
apply test voltage of any kind while machine is under dehydration vacuum. Motor 
insulation breakdown and serious damage may result.
