EAR PROTECTION IS REQUIRED DURING BLOW DOWN DUE TO EXCESS NOISE!
WELL VENTILATED AREA, PROTECTIVE EYEWEAR AND GLOVES REQUIRED!
1. Make sure all ball valves are in the closed position.
2. Disconnect Nitrogen supply lines. Marked as #4.
3. Disconnect chemical supply lines at the Stratoflex fittings. Clean Stratoflex fittings and move cylinders to
well ventilated area.
4. Read Pressure Gauge on cylinder marked #4.
5. Slowly open blow-down ball valve marked as #1 while watching pressure gauge until it reads 75 p.s.i. for
froth and 25 p.s.i. for liquid-blown systems. #4 must be open to do this.
6. If chemical starts to discharge from the blow-down ball valve marked #1, close valve and stop the Blow

IMPORTANT: DO NOT REMOVE CYLINDER FITTINGS! REMOVAL OF FITTINGS COULD RESULT
IN VIOLATION OF FEDERAL LAWS SUBJECT TO PENALTIES AND FINES, AND WILL
RESULT IN CHARGES FOR THE COST AND LABOR TO REPLACE FITTINGS.
Empty cylinders being returned to Foam Supplies, Inc. for refilling must be sealed and the pressure relieved.
For cylinders being shipped as UN3500 the pressure should be at 75 psi. This procedure is necessary in
preventing possible contamination in the cylinder fittings. For liquid-blown blown systems the pressure must
be reduced to 25 psi or lower in order to be considered non-hazardous. Failure to do so is a violation of
federal regulations and can result in fines and penalties by DOT and/or OSHA.
