Overview
The 14 GPM Gemini High Flow Level Master™ is a water driven chemical proportioner that will dilute and blend 2 chemicals and automatically refill a customer-supplied tank with ready-to-use chemical solution at 14 GPM @ 40 PSI. When the solution in the tank drops below a pre-set level, the float valve triggers an air-activated solenoid to start the water flow. The unique Gemini™ "double venturi" injection system combines two completely separated venturis in one injector body and uses city water pressure (35 - 125 PSI) to draw and blend 2 chemical concentrates into the water stream independently so that the chemicals never mix until they are diluted. The system cycles continuously and a secondary fail-safe float prevents overfilling.

Problem | Possible Cause / Solution | |
---|---|---|
Startup | Maintenance | |
A) Mixing station will not draw chemical. B) Dilution too strong. C) Dilution too weak. D) Primary float will not activate (does not fill) E) Primary float valve will not turn off (overfills or triggers secondary fail-safe float valve on double-float models) NOTE: This guide is for Air Level Masters used with High Flow Satellite Mixing Stations | 1, 4, 5 2 3, 4, 5 7, 9 6, 7, 8 |

PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing. |
