Safety & Operational Precautions
To Install (refer to diagram on next page)
Set the chemical dilution ratio by threading one of the color coded metering tips into each chemical check valve. See chemical labels for dilution ratio recommendation or consult your chemical supplier.
OPERATION INSTRUCTIONS
Always make sure the discharge ball valve is closed or pointed in a safe direction before turning the air on. Ball valve can be shut off at any time during operation but should not be left unattended for long periods of time. Expect a strong blast when re-opening ball valve.
The unit has been tested and is ready to operate. The pump air pressure regulator is preset and locked at 65 PSI. This is the optimum pump pressure for this unit. Test "as is" before making any foam consistency adjustments.

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. |
