INSTALLATION
1. After the existing Check Valve Assembly (A) has been removed, examine the machined Seating Surface (F)
on the Venturi Housing (D) to be sure the surface is clean and without flaws.
2. Screw the Clevis (I) into the Venturi Housing (D), until 3 – 3 1/2 threads are left inside of the housing.
Do not use a screwdriver or other prying device to install the clevis.
3. Insert the Check Valve Arm (K) into the slot of the Clevis (I) and connect the two pieces with the clevis/arm
Pivot Screw (L) through the aligned holes. Be sure that the flat washers are inserted on either side of the
clevis. Tighten the Lock Nut (J) allowing for free swing of the arm.
4. Check for proper Clevis installation as follows:
a) With the Check Valve Arm (K) raised, rotate the Check Valve (M) around the valve/arm pivot so that the
edge of the valve nearest the Clevis (I) is lowered without allowing the Check Valve (M) to turn around the
valve/arm pivot. Only the lower part of the valve should contact the Seating Surface (F).
