BECOME ALERT! YOUR SAFETY ISINVOLVED! FAILURE TO FOLLOW THESE INSTRUC-TIONS MAY RESULT IN A SAFETY HAZARD.CAUTION:All work must be performed by quali-fied personnel trained in the proper application,installation, and maintenance of systems inaccordance with all applicable codes and ordinances.CAUTION:Over-tightening and breakage can occur with the use of Teflon pipe joint compounds.Teflon provides lubricity so thatcare must be exercised not to over-tighten joints.Failureto follow these instructions could result in property damage and /or personal injury.WARNING:System fluids are under pressure or temperature can be hazardous.Be sure thepressure has been reduced to zero and the system temperature is below 100°F (38°C).Failure to follow these instructions could result in property damageand/or personal injury.Note:Anapproximate 30 second delay is possible in valve movement after beingpowered on.For heating applications, it is important to cycle the N/O valvesperiodically during the off season or power them down to reduce thechance of the valve sticking in the up coming heating season.Next >
