INSTALLATION
To install a 4-FV, the 4-FV Fitting and Coupling
Nut should be assembled with the appropriate
cartridges into the discharge port of the pump.
Use a 13/16” or 20 mm socket to tighten fitting.
Tightening to 50 inch-pounds is recommended.
Do not over tighten
. To assemble the 4-FV body,
assemble the coupling nut and the threads at the
bottom of the body. Firmly hand tighten the body
in the desired orientation. Next, insert the 1/4”
tubing through the bleed nut. Ensure that about 1/4”
(6 mm) of tubing is protruding through the tip of the
bleed nut. Firmly hand tighten the bleed nut in the
hole on the side of the 4-FV. This tubing should be
routed back to the supply tank. To ensure proper
function of the priming function, the end of this
tubing should not be submerged in the solution.
THIS RETURN LINE TUBING
MUST BE SECURED TO ENSURE
PUMPED SOLUTION WILL SAFELY RETURN TO SUPPLY TANK.
