Water supply line; water pressure must be

between 25 psi and 80 psi (175 kPa and

550 kPa); water conductivity minimum

100 µS/cm. If water piping to humidiﬁer is

nonmetallic, we recommend that the ﬁrst

3' (1 m) of water supply piping from the

humidiﬁer be metallic

Steam vapor hose (maximum

run 10' [3 m]). May also use pipe

or tubing. See the DRI-STEEM

Design Guide for maximum pipe

or tubing lengths.

piping run is over

10' (3 m) increase

pipe to 1¼" (DN32)

after P-trap.

Notes:

• Locate air gap only in spaces with adequate temperature and air movement to absorb ﬂash steam; otherwise, condensation may form on nearby surfaces.

Refer to governing codes for drain pipe size and maximum discharge water temperature.

• Offset humidiﬁer from spill funnel or ﬂoor drain to prevent ﬂash steam from rising into the cabinet.

• Dashed lines indicate provided by installer.

• The water supply inlet is more than 1" (25 mm) above the skim/overﬂow port, eliminating the possibility of backﬂow or siphoning from the tank. No additional

backﬂow prevention is required; however, governing codes prevail.

• Install a union in the water supply and drain lines as shown to allow tank removal.

• Damage caused by chloride corrosion is not covered by your DRI-STEEM warranty.

• See the next page for recommended piping for Vapormist-DI models (models that use DI/RO water).

• See the dispersion section of this manual for more information about piping that connects the humidiﬁer to the dispersion assembly.
