Water Pump and Regulator

Viper — Operation

1. Water Pump and Regulator

   The water pump must first be primed with water before adding CO2 to the unit. When connecting water to the unit, you must manually bleed the water valve on at least one barrel to assure the water pump is filled with water.

   The Viper’s internal water pump is gas driven by the incoming 75psi CO2 pressure to the Viper. The incoming water pressure to the Viper is recommended to be between 25psi and 90psi dynamic pressure. The current in-line water regulator is now black in color and preset for 30psi. A prior version water regulator was white with a built in strainer.
