2.8 PLUMBING CONNECTIONS
PLUMBING THE CHEMICAL METERING VENTURI
It is important that the Chemical Metering Venturi is plumbed correctly or the
system will not function properly and the warranty will be void.
The chemical metering venturi injector requires a pressure differential across the venturi
to achieve the rated chemical flow. A booster pump is needed to ensure the required
pressure differential is achieved. The NEXGEN will provide 100% of the rated output with
a maximum of 25 PSI at the venturi outlet. Install the booster pump in the supply line to
the venturi. Consult ChlorKing for booster pump sizing.
The booster pump is powered by the NEXGEN and must be installed within 10 feet
of the NEXGEN skid to ensure the electrical connection will reach the pump. The
pump wiring is located on the bottom side of the enclosure. Wire the booster pump
to the NEXGEN with the cable provided and to the pump according to the
instructions on the pump for 208/240 VAC connections. The NEXGEN ships with a
12amp breaker for a 1HP pump. Larger pumps will require changing the breaker.
Contact ChlorKing for breaker sizing.
