INSTALLATION
1.The spring pilot valve can be installed on either
side of the main valve. The main valve is
shipped with the U-tubing and the bleed orifice
installed for left-hand side mounting of the spring
pilot valve. If right-hand side mounting of the
spring pilot is desired, the U-tubing and the bleed
orifice must be relocated to the opposite sides of
the main valve.
Note: Right-hand side positioning occurs when
the main valve inlet directly faces the observer.
Figure 1 illustrates mounting the spring pilot on the
right-hand side of the main valve.

• The mounting hardware kits contain all of the hardware required to install the spring pilot valve
on the main valve.
• Pipe sealant should be applied to all pipe threads. Do not use Teflon
®
tape. Note: Follow
manufacturer’s instructions for applying pipe sealant. Keep sealant off first thread.
• The preformed copper tubing (included in the hardware kits) may have to be shortened with a
tubing cutter. Ream to restore original inside diameter of tubing. Avoid getting chips in the tubing
or piping.
