3.2 LEFT or RIGHT HAND OPERATION

The Control Block and Valve Assembly can be mounted on the Foam Tank for right or left hand operation. To switch hands, remove the
Shoulder Strap from the Pull Pins. Remove the Circle Cotters from the Pull Pins and remove the Pull Pins themselves. Pull the Control
Assembly straight up and out of the tank. Turn the Control Unit around and reinstall the Pull Pins, the Circle Cotters, and the Shoulder
Strap.

4.0 FOAM SELECTION

In any eductor type system the accuracy of the foam concentrate to water ratio will depend upon the viscosity (thickness) of the
foam concentrate. The more viscous, or thick, the foam concentrate, the greater the amount of energy required to draw the
concentrate into the eductor. The viscosity of most foam concentrates changes with temperature, some thickening to a gel at
temperatures of 40º F (4º C).
The PRO/pak percentage knob has two sides, the green Class A side was calibrated for 20 Centipoise Class A foam concentrates and
the red, Class B, side was calibrated with National Foam's Universal Gold® AFFF concentrate.
Class A foam concentrates are generally less viscous than Class B foam concentrates. Do not use 1
CAUTION
percent Class B concentrates with the percentage knob set at 1 percent on the Class A side of the knob.
Using 1% Class B foam on the 1% Class A setting may cause the actual percentage to be less than 1%.
Actual foam concentrations vary with changes in water flow, foam concentrate temperature and viscosity. The user must verify that the
concentrate's performance is suitable for use in their application. In all cases, the manufacturer's recommendations must be followed.
