Operation
When the humidification system has been installed and commissioned it will function as
follows:
1 The humidistat calls to the valve controller for humidity.
2 If On-Off Safety controls (air proving, high limit humidistat) are closed, the humidifier will
activate.
3 The pump module will activate and charge the lines to 1000psi.
4 The soft charge valves will open, softly charging the manifolds to prevent water hammer
effects.
5 The valve assembly will open valves as needed to provided water flow to the manifolds. The
manifolds will then spray water into the air stream, humidifying the air.
6 When the humidity targets have been met, the valve controller will close the valves and shut
off the pump, stopping the spray of water.
7 Water will drain from the manifolds to reduce the microbial growth that may occur in
standing water. An air break cap at the top of the manifolds will allow air to enter the lines
to facilitate this process.
8 Once every 24 hours, the valve controller will activate the system for 2 minutes to purge the
lines of any standing water. This process occurs regardless of demand for humidity at that
time.
