measured length for pipe fittings.
Note: To minimize loss of humidifier
capacity and efficiency, the tubing/

Vapor Hose
• Vapor hose should be supported to
prevent sags or low spots and to
maintain a minimum pitch of 2" per
foot back to the humidifier.
• For mounting the humidifier above
the level of dispersion tube, see figure
8-2 on page 8.
Failure to follow the above recommen-
dation may result in excessive back
pressures being imposed on the humidi-
fier. This in turn may lead to dispersion
tube(s) spitting, lost water seals or
leaking gaskets. When the distance
between humidifier and the dispersion
tube(s) exceeds 10 feet, consult factory
for special recommendations.
Rigid Piping
• Vapor piping should have a minimum
I.D. equal to the cover outlet of the
humidifier.
• A minimum pitch of 2" per foot back to
the humidifier should be maintained.
• 90° elbows are not recommended, use
two 45° elbows one foot apart instead.
• Thin-wall tubing will heat up faster and
cause less start-up loss than heavy-
wall pipe.
• Insulating the rigid piping will
reduce the loss in output caused by
condensation.
Tube Mounting
• Mount dispersion tubes pitched
as stated above.
• Tubelets must discharge perpendic-
ular to air flow.
* Return line piping material must be
suitable for 212°F (100°C) water.
Min. Condensate Drain Line Sizes
• One or two tubes: 3/4" I.D.
• Three or more tubes: 1" I.D.
