Page 13: Characteristics Of The Supply Water
CHARACTERISTICS OF THE SUPPLY WATER The humidifi er must be supplied with water with the following characteristics: • Incoming Pressure: Between 20psi and 90psi or 0.1 and 0.8 MPa (1 - 6 bar) • Maximum intermittent pressure: 110psi (8 bar). Maximum intermittent pressure includes water hammer or other supply water pressure spikes. -
Page 14: Water Connections
Figure 3.d.). Water Drain and Drain Hose The GF-5500 Steam Humidifi er requires a connection to a drain. A 10’ length of ¾” ID drain hose is included with unit. Attach the drain hose to the water drain fi tting and secure with the hose clamp provided. -

Turbulent air fl ow may require Height >8” longer lengths. 8” Steam Manifold (included) The GF-5500 Steam Humidifi er comes standard with an 8” steam manifold. An optional steam nozz- le and steam manifolds are available separately for 1/3 Height other installations. - Page 16 Steam Nozzle (optional) The optional steam nozzle (See Figure 3.h. and Table 3.d.) can be used for horizontal surface installations (i.e. the bottom of a horizontal duct) or vertical surface installations (See Figure 3.i.). A condensate hose is requi- red. To install the steam nozzle, cut a 2-1/2” round hole in the duct. Apply silicone sealant to the mounting plate and insert the nozzle through the hole and secure with sheet metal screws.

Page 17: Steam Manifold (12" & 17.5" Options Available)
STEAM MANIFOLD (12” & 17.5” OPTIONS AVAILABLE) For certain applications, a longer steam manifold may be required. Select an accessible location on the duct, allowing at least 36” of straight duct (no elbows or obstructions) after the point where the steam manifold will be installed and the clearances can be maintained as per the following drawings. -
Page 18: Steam Hoses
STEAM HOSES To avoid these problems, remember one simple fact when running the steam hose: steam naturally fl ows up hill and condensate naturally fl ows downhill. Run the steam hose or piping to avoid any kinks, sharp elbows, or low spots that could collect or restrict the fl ow of steam to the distributor manifold, or the fl ow of condensate back to the humidifi er. -
