7. The use of resin cleaners in an unvented enclosure is not recommended.
Water Line Connection
The installation of a bypass valve system is recommended to provide for occasions
when the water conditioner must be bypassed for hard water or for servicing.
The most common bypass systems are the Autotrol
® Series 256 bypass valve
(Figure 4) and plumbed-in globe valves (Figure 5). Though both are similar in function,
the 256 Autotrol bypass offers simplicity and ease of operation.

Drain Line Connection

drain. For such installations, use an appropriate adapter fitting (not supplied), to
connect 1/2-inch (1.3-cm) plastic tubing to the drain line connection of the control
valve.
