5.2. Air-Release Valve

After initial operation of the MixRite, press the cap
(air release valve) for several seconds to open
valve that allows trapped air to escape. This air
release is accompanied by a slight loss of water.
Release the cap to close the valve.

5.3. On/Off System

Important!
On pumps with On/Off knob there is no air-release
valve.
It is highly recommended to use the On/Off knob
when the additive container is empty, or if there is a
need for the water flow to continue without the
additive.
ON position- The knob should be in its high position;
the pump is working and pumping.
To turn on, push and turn CCW.
OFF position- The knob should be in its low
position; the water flow continues without the
pumping action.
To turn off, push and turn CW.
