Use care when handling the valve cartridge. Slight bending or
distortion of the stem tube can cause binding and malfunction.
B. Fit cartridge valve carefully into manifold port. The valve should go in
easily without binding.
C. Tighten the cartridge valve using a deep socket (valves that thread
directly into the manifold block) or an extended hex wrench socket (flange
mounted cartridge valves) to the value identified in manifold service
illustration.
D. If cartridge uses a replaceable solenoid coil, carefully install solenoid
coil to the cartridge valve. Tighten coil nut to value identified in manifold
service illustration. Over−tightening may damage the solenoid or cause
the valve to malfunction.
8. If problems still exist, remove valve and clean again or replace valve.
