10-00 Page 3 2008-10-01 1. INTRODUCTION The NHTC humidifier is controlled by Nortec’s Patented Auto adaptive Water Management Control System. This system allows the hum idifiers to adapt to basically any potable incoming water and changes that occur to the water supply. This eliminates the need to readjust drain timers, changes complete cylinders[...]

10-00 Page 4 2008-10-01 (6) As the water is boiled away, the minerals left behind increase the conductivity of the water in the cylinder. As soon as the conductivity is greater than design, the Ta to boil from A to D will be shorter than To and a drain cycle is initiated. (7) The fill valve always opens during timer drains, adding cold water to mix[...]

10-00 Page 8 2008-10-01 It is important to note that the drain rate shown includes the make-up water, mixed with the drain water, which tempers the drain water to 140°F (60°C) or less. NOTE The electrode steam process provides optimum efficiency because all re sistance to current passage is converted to usable energy. Unlike cal-rod or infrared h[...]

10-10 Page 34 2008-10-01 (3) NORTEC recommends the use of insulated ha rd copper steam lines on distances o f more than 10 feet and no more than 3 elbows (90 ⊃ ). The use of flexible steam hose on runs of more than 10 feet can reduce these recommended distances in Table 14 by as much as 25%. Steam hose can crimp and cause back pre ssure. Table 14[...]

10-10 Page 35 2008-10-01 (2) Use vertical condensate leg of distributor only. Do not over-tighten clamp. (3) Drip stations on steam mains must be located at all low points in the system, at each elevation change and or directional change. (4) Horizontal runs of steam must have a 2" rise per foot (10°) when flow is going away from drip sta tio[...]

10-10 Page 36 2008-10-01 (7) Vertical drop of the drip station should be 1.5 times the diameter of th e steam main b ut no less then 12". (8) Install the P trap at the botom of the drip station. The P trap height is to be a minimum of 6 inches or 2 “ greater than the stat ic pressure in the duct. (9) All distributors must be individually tra[...]
