SOLVENT CEMENTING INTO A 1 1/2” HAYWARD SOCKET x THREADED BULKHEAD FITTING
1. Remove the self adhesive HAYWARD label from the outer surface of the Vacuum Breaker valve. 2. Clean the surface thoroughly, being sure to remove all traces of the label adhesive. Light scuffing with a fine sandpaper or emery cloth is acceptable. 3. The end of the Vacuum Breaker valve having the 3/4” N.P.T. thread MUST face the pressurized or fluid side of the pipe. 4. Using a scrubbing motion, apply P.V.C. pipe joint primer to the inside of the fitting that the Vacuum Breaker valve is to be installed into. Repeat applications may be necessary to soften the surface of the socket. 5. Carefully apply primer to the OUTSIDE SURFACE ONLY, of the Vacuum Breaker valve, taking care as to not allowing primer to enter either end of the Vacuum Breaker valve openings. Doing so may damage the valve and cause it to malfunction. 6. Lightly apply a good grade of P.V.C. solvent cement uniformly to the inside of the socket connection of the fitting into which the Vacuum Breaker valve is to be inserted. 7. Holding the Vacuum Breaker valve by the end HAVING the 3/4” N.P.T., carefully apply a light coat of P.V.C. solvent cement uniformly to the outside surface of the Vacuum Breaker valve, taking care as to not allowing any of the cement to enter either end of the Vacuum Breaker valve openings. 8. Insert the end of the Vacuum breaker valve OPPOSITE the 3/4” N.P.T. into the female socket fitting, using a rotating motion. 9. Allow cement to dry for at least 4 hours before pressurizing system. EXTREME CAUTION MUST BE TAKEN WHEN WORKING ON THIS VACUUM BREAKER VALVE. THE PIPING SYSTEM MUST BE DEPRESSURIZED AND DRAINED. PROPER CARE MUST BE TAKEN. CONSULT M.S.D.S. (MATERIAL DATA SAFETY SHEETS) FOR INFORMATION REGARDING YOUR SPECIFIC PROCESS FLUIDS. VENTIS REV D 9/17/99 ECR 819R
