Plumbing






All water supply and drain line connections should be installed in accordance with local

plumbing codes.

Supply water should have pressure between 30 and 80 psi

g

and have a hardness

between 0 and 12 gr/gal. Various types of supply water may be used: soft water, de-
ionized, reverse osmosis, or potable.

Install water shut-off valve and union before humidifier to facilitate servicing.

The drain line should not end in a sink used frequently by personnel, or where plumbing

codes prohibit. Route to a floor drain or equivalent for safety reasons.

Ensure drain line is adequately sized to provide free and easy draining. Ensure air gap is

installed as shown. A restricted drain can cause the boiling tank to become heavily
concentrated with minerals and may result in poor operation or water backing up at the
air gap.
