Blocking Solenoid Valve For Multi-tank Alternating Operation
NOTE Proceed to page 47 if your system is a single tank configuration. The solenoid valve is only required for
multiple unit alternating or progressive flow systems.
The purpose of the solenoid valve is to assist the controller in providing automatic alternation of multiple tank systems.
Each Brunermatic multiport valve in the system will require its own solenoid valve. These solenoids are tubed as follows:
• From solenoid valve port number 1 to Brunermatic multiport valve port number 4.
• From solenoid valve port number 2, tee into the tubing that attaches to the “IN” port on the pilot valve body.
• From solenoid valve port number 3 to port number 2 on the pilot valve body. The detailed tubing schematic is
shown below (Figure 30).
