ATTACHING THE LINE CORD

 

 

BEFORE CONNECTING CONTROLLER TO AC POWER SUPPLY CHECK THE 
SETTING OF THE VOLTAGE SELECTOR MODULE. 
 
This module is on the back panel, bottom left. There are four settings. Be sure selector is set 
for your power requirements. A red indicator should be visible beside the correct voltage in 
the list printed on the fuse cover. If the red indicator does not mark the correct voltage, the 
card inside the fuse case must be pulled out and reinserted with the proper orientation.  

 
Please note: The controller can be set to 120V or 240V.However the pump and tank unit 
does not have voltage setting adjustments. Use PTU-110A for 110/120V and PTU-220 for 
220/240V operation.
