Installation & Maintenance Manual
22
To clean the fill and drain valves:
After shutdown and removal of the steam cylinder, shut off the
water supply to the humidifier, disconnect the water supply and
remove the fill valve from the humidifier. Remove the inlet strainer
by reaching up into the fill valve inlet with a pair of needle nose
pliers and pulling out the strainer by its tab. Clean the fill valve and
inlet strainer using the same solution as used to clean the steam
humidifier, but DO NOT soak the solenoid coil in fluid. Reinstall the
fill valve.
WARNING: When cleaning fill valve, do NOT poke or probe
flow regulator with any object which may enlarge the orifice.
The flow regulator must meter water flow precisely or
shortened cylinder life may result.
Remove the drain valve group and disassemble it. Clean all parts in the same way as the fill valve, reassemble and
reinstall.
After cleaning and reassembly, restart your humidifier according to the Startup Instructions contained in this manual.
