Condensate Lines
–
The condensate drain line from the steam distributor must have a constant minimum downslope of
1 in/48 in (1.2°), with a minimum trap height of 8 in (200 mm), and may be connected to the fill cup
port on the top of the humidifier, or to the building floor drain with condensate cooler as required. The
condensate trap must be at least 12 in (300 mm) below the condensate port on the steam distribu
-
tion system or the "T" connector in the steam line. Refer to

WARNING!
Risk of severe burns from hot fluids or steam!
The condensate lines may be filled with hot fluids or steam. Bare skin in contact with hot fluids
or steam can result in severe burns.
Prevention
:
Never plumb the condensate lines to empty into a sink used by personnel. Always
connect the lines to a drain according to applicable national and local plumbing codes.
–
Condensate lines must also be installed at all low points and at vertical transitions in the steam
line. The condensate drain lines should always connect to full-size "T" connectors in the steam line.
Install full-size "T" connectors for condensate drain lines at all transitions from vertical to horizontal.
–
For a steam line that is longer than 15 ft (4.5 m) up to the maximum recommended length, install
condensate lines and traps at regular intervals. The maximum distance between the condensate
traps for long runs is 15 ft (4.5 m).
–
Use 3/8 in (9.5 mm) Nortec condensate hose, or 3/8 in (9.5 mm) stainless steel pipe or 1/4 in (6.5 mm)
copper pipe for traps in the condensate lines.
–
Make sure that the condensate lines allow proper flow.
–
Do not over-tighten the hose clamps on the condensate lines.
IMPORTANT!
Before starting up the unit, prime the traps in the condensate lines with water.
