• If painting is required, use only latex based paints.
• Keep pipe and fittings in original packaging until needed and away from sources of heat.
• If stored outdoors, cover the pipe and fittings with an opaque tarp.
• Follow proper handling procedures.
• Inspect TYCO CPVC Pipe and Fittings for damage before installation.
• Use tools specifically designed for use with CPVC pipe and fittings.
• Use only TFP-500 or TFP-600 One Step Solvent Cement and follow application instructions.

• Follow the recommended cure times prior to pressure testing.
• Fill lines slowly and bleed the air from the system at the farthest sprinklers prior to pressure testing.
