To facilitate servicing, a shut off valve (not supplied) should be installed in the water supply line, close to
the humidifier.

If required, an air chamber made of copper pipe (see fig. 9) will absorb hydraulic shock, avoiding water
hammer, when the fill valve closes. There are other standard types of air chambers commercially
available.
