Drip tee installation
Install a drip tee as shown below when the humidi-
fier is mounted higher than the dispersion device,
when interconnecting hose or piping needs to go
over an obstruction, or when interconnecting piping
runs are long. IMPORTANT: Vapor hose must be
supported to prevent sagging or low spots.

Maximum steam carrying capacity and
length of interconnecting vapor hose,
tubing and pipe*
Notes:
* Based on total maximum pressure drop in hose,
tubing or piping of 1250 Pa
** Maximum recommended length for vapor hose is 3 m.
Longer distances may cause kinking or low spots.
*** To minimize loss of capacity and efficiency, insulate
tubing and piping.
†
Developed length equals measured length plus 50%
of measured length, to account for pipe fittings.
Note:
This data is based on an ambient air temperature of 27 °C,
fiberglass insulation, copper tubing and schedule 40 pipe.
