Installation
The vent is installed in the vertical position, on the air
separator, on manifolds, on riser pipes and generally in
parts of the system where a concentration of air pockets is
to be expected.
Check valve on 5027 series should be installed prior to air
vent. Insure air vent is properly lined-up with female check
valve guide.
Service Instructions
There is no service required for the automatic air vent.
Operation Instructions
The automatic air vent can be used for manual or automatic venting of sealed hydronic
systems.
• For normal automatic venting, open cap one full turn for a slow release of air. A fast release
of the air will allow dirt or scale in the water to plug the operating mechanism. The small hole
in the side of the cap allows air to escape.
• To shutoff automatic air vent, screw cap down tight.
CAUTION:
Corrosion or leakage can cause damage or injury.
Periodically inspect for signs of corrosion or leakage. If corrosion or
leakage is note, the vent must be replaced. Failure to follow these
instructions could result in property damage and/or personal injury.
CAUTION:
Uncontrolled venting of water can occur with the automatic
air vent if dirt, scale, pipe joint compound or any other foreign materials
becomes trapped in the operating mechanism. Keep vent cap closed
during filling to prevent dirt from flowing into vent mechanism. Failure to follow
these instructions could result in property damage and/or personal injury.
