Do not mount on vibrating surface. Do not mount on floor. LiveSteam produces steam at atmospheric pressure no devices which could block steam output should be connected to the steam outlet. Steam lines must be installed so that no restriction can produce backpressure in the humidifier.
Receiving & Unpacking Equipment 1 Check packing slip to ensure ALL material has been delivered. 2 All material shortages are to be reported to Nortec within 48 hours from receipt of goods. Nortec assumes no responsibility for any material shortages beyond this period.

(LOC. 2) will go downstream to the mixing boxes and will be controlled by a humidistat in the space. Please consult your Nortec agent if absorption distance is a problem. High limit humidistat is recommended in the mixed air duct.
See Figure 8. 2 For removal of condensate from the steam trap the condensate line should not be under pressure. Nortec recommends a check valve be installed after the steam trap if the condensate return line is pressurized.
5 It is also possible to install distributor in the duct and then attach the separator/valve assembly. 6 Follow the steps listed in “Installation Of LiveSteam Humidifier” section to complete installation. Assembly Of Multiple Distributor Humidifier Make a plan of distributors’ layout (if not already done). See Figure 8. Multiple distributor humidifiers require field assembly.
Figure 9: Multiple Distributor Humidifier with Multiple Traps 6 Follow the steps listed in “Installation Of LiveSteam Humidifier” section to complete installation. Installation Of Livesteam Humidifier Note: Follow all general instructions provided with valve and actuator. To complete installation follow the steps listed below.
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.
