INSTALLATION INSTRUCTIONS
Important-
 Read these instructions before installing the valve. Use the correct “Rough-in Diagram” for the unit that is 
being installed. Maximum water pressure: 125 PSI static; minimum water pressure: 20 PSI flowing; minimum cold 
supply temperature: 40° F; maximum hot supply temperature: 160° F; minimum hot supply temperature: 5° F above set 
point. Use a suitable sealant on all threaded connections and when soldering, it is recommended to remove the integral 
check stop valve parts and VC/DIV cartridge (If applicable). The valve rough-in adjustments are 2-1/2” to 3-1/2” from 
the finished wall to the centerline of the hot & cold inlets of the valve body. 
1) Referring to the correct “Rough-in Diagram” for the unit 
that is being installed (See the back page or the separate 
insert sheet), install the hot & cold supply lines for the 
valve, making sure they are on an accurate horizontal 
plane. Taking the valve assembly, making sure the “UP” 
on the valve bonnet is in the up position, connect the hot 
supply line to the left side of the valve & the cold supply 
line to the right side of the valve (Note that for Back- To- 
Back valve installations, the hot & cold supply lines are 
reversed on the opposite valve). Make sure the valve is 
straight, level, & positioned properly in the wall (See 
Figure 1). See Page 3, Figure #4 for “Back-To-Back” 
valve cartridge installation instructions.
