SAFETY INSTRUCTION This safety alert symbol will be used in this manual to draw attention to safety related instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.
DESCRIPTION The No. 97 is a float type automatic air vent and is designed to vent the accumulation of troublesome air whenever it can be trapped.
INSTALLATION INSTRUCTIONS CAUTION: Uncontrolled venting of water can occur with the automatic air vent if dirt, scale, pipe compound or other foreign material fouls the operating mechanism. Keep vent cap closed during system filling to prevent dirt from running into vent mechanism. Failure to follow these instructions could result in property damage and/or moderate personal injury. CAUTION: Hot venting can be hazardous. Avoid contact with venting fluid and only manually vent when system temperature is below 100°F (38°C). Failure to follow these instructions could result in property damage and/or personal injury. CAUTION: Overtightening and breakage can occur with the use of PTFE pipe joint compounds. PTFE provides lubricity so that care must be exercised not to over tighten joints. Failure to follow these instructions could result in property damage and/or moderate personal injury.
