Introduction
Thank you for purchasing the
Rapid Initial Air Vent.
This product has been thoroughly inspected before being shipped from the
factory. When the product is delivered, before doing anything else, check the
specifications and external appearance to make sure nothing is out of the
ordinary. Also be sure to read this manual carefully before use and follow the
instructions to be sure of using the product properly.
This Rapid Initial Air Vent is for use on water-bearing pipes, and should
therefore not be used on steam lines.
The Rapid Initial Air Vent operates by rapidly discharging the initial air when
supplying water to piping, then closing upon completion of discharge. During
operation, once it has closed, the air vent remains closed as long as there is
internal pressure. When draining piping, the Rapid Initial Air Vent automatically
opens to introduce air and remove water easily.
The Rapid Initial Air Vent ‘s simple, compact construction, with no hinges or
levers and only one moving part, the float, provides trouble-free operation and
long service life.
If detailed instructions for special order specifications or options not contained
in this manual are required, please contact
for full details.
This instruction manual is intended for use with the model(s) listed on the
front cover. It is necessary not only for installation but for subsequent
maintenance, disassembly/reassembly and troubleshooting. Please keep it in
a safe place for future reference.
