5-FUNCTION VALVE
INSTALLATION OPERATION MAINTENANCE INSTRUCTIONS
1. Tubing Version: Remove the tubing nut from the discharge valve cartridge on the top of the
pump head. Install the supplied Viton O-ring (#L1501200-VTN)* into the groove around the
tubing tip on the valve cartridge. Hand-tighten the 5-Function Valve onto the discharge valve of
the pump. Connect the discharge tubing to the “OUTLET” port and the bypass tubing to the
“RETURN” port of the 5-Function Valve.
**PRESOAK TUBE: Prior to assembly soak tube end in 180°F to Boiling Water (approx. the
water temperature from the discharge of an office coffee maker). Soak time should be a
minimum of 30 seconds.
2. NPT Version: Apply plumbers tape or sealant to the threads of the 5-Function Valve. Screw
“INLET” connection into the discharge valve of the pump head. Connect piping to the
“OUTLET” and “RETURN” port connections of the 5-Function Valve.
*If Viton is not compatible with fluid being pumped and alternate Teflon O-Ring is available
(L1501200-TFE). Viton is the preferred sealing material with difficult to seal fluids like
Sodium Hypochlorite and similar
