1.  A 24 VAC power supply transformer is furnished with the manifold control unit. Mount the box onto the wall, to the 

left of the manifold, with the top edge approximately aligned with top of the control unit. The attached control cable 

terminates into a 7 prong plug matching a receptacle on the left side of the control unit, (Figure 8). 

 

 

2.  After mounting the power supply box to the wall, plug the cable into the control unit receptacle.

3.  The center hole on the underside of the power supply box provides access for conduit and connection of 115 VAC 

power. Connect the 115 VAC black and white leads to the power supply as shown. (Figure 9) 

4.  Connect the ground wire to the ground terminal as shown in figure 9. 
 
5.  After completing the 115 VAC connections, the power supply should be completely installed and 115 VAC power 

can be applied. 

 
6.  Manifolds with heater have a 3 prong cord that should be plugged into a standard 115 VAC that can provide 4
