Nortec LiveSteam v.2 - Manual (Page 13)

LS Installation Manual | 10
10 Wire (electric) or install control tubing (pneumatic) to the valve actuator.
11 Industry standards recommend the use of drain pans under the steam distributor.
12 Nortec recommends the use of a temperature switch. Valve will not open until the
distributor has reached its operating temperature. This is optional and must be ordered.
13 Nortec recommends the use of an air proving switch to prevent wetting in the duct.
Humidifier will not operate if there is no air movement in the duct.
14 A high limit duct humidistat, which prevents saturation and wetting in the duct, is
recommended downstream 12-14 feet from the humidifier and set at 80 to 90% RH.
Changing Orientation Of Single Distributor Humidifier
Unless otherwise specified at the time of order placement, all uninsulated single tube
distributors will be shipped with right face assembly and steam outlets facing the air stream
(See Figure 10). The steam flow direction can be changed by opening the union and
disengaging the nipple / elbow assembly from the steam distributor, turning the tube assembly
180º and reinstalling the nipple / elbow assembly.
Warning: LS distributors are designed to be supported by the steam piping connected to the
unit. Failure to properly support steam piping can result in stresses on the tube adapter and
damage the o-ring.

Insulated Steam Distributors
When the steam distributor is insulated the distributor should discharge in the direction of air
flow. This is to prevent condensation build-up on the steel insulation jacket.
Duct Support Bracket
Duct support bracket allows for easy installation in the various duct configurations (Figure
#11,12,13,14).
It is designed to be used with maximum bolt size of 3/8" (M10). LS1 and LS2 distributors that
are 12” (30.5 cm) long are not supplied with duct support brackets.
