Installation Of Livesteam Humidifier
Note: Follow all general instructions provided with valve and actuator.
To complete installation follow the steps listed below.
1 Steam outlets of distributor should face into the air stream unless distributor is insulated.
Nortec’s standard is right face.
2 Distributors must be mounted level. There is a support bracket at the end of the distributor
to secure to the duct wall. See Figure 11 to 14 for installation tips.
3 The steam distributor in a Single Distributor Humidifier should be centered in the duct.
4 The steam distributor should be mounted in a straight section of duct. Please consult your
Nortec agent if absorption distance is a problem. For calculation of absorption distance
please refer to Nortec manual Form #163D.
5 Do not locate the steam distributor within 10 feet of high efficiency filters, otherwise the
filter will become saturated.
6 Cut a hole in the side of the duct large enough to insert the steam distributor. Duct plates
are provided to seal any opening.
7 Install actuator. During installation follow instructions shipped with actuator.
8 For ease of maintenance, provide shut-off a valve before humidifier (between strainer and
steam main). It can also be used to minimize heat gains during the non-humidification
period.
9 Install strainer before entering system and steam trap. Connect to steam and condensate
return mains.
