Service and Drain Piping:
1. Pipe Filter into the service lines .The inlet and outlet connections of the
control valve are 1” copper or PVC and are located on the back of the
valve body. As you face the timer the inlet is on the left and the outlet is
on the right. Always follow local plumbing codes when installing our
water treatment equipment.
2. If sweat fittings are used, be sure soldering is done in such a manner
as not to allow heat to reach the control valve or bypass. (If Schedule
80 PVC is used make sure to follow the proper primer and solvent
instructions.)
3. The drain line connection is located on the back of the control valve as
you face the timer. It is recommended you install a 3/4” union on the
drain line for servicing. The drain line must be of adequate size to allow
for full regeneration flow.
