Suitable locations
to install your Ultra-Zone Steam Humidifer on an Up-flow or Horizontal
HVAC System. Notice that some of the locations are X’d out. These are poor locations for
the Steam Humidifer and may result in lower capacity output and/or excessive
condensation. Try to avoid mounting the unit within 2 feet of any 90 degree turns. Allow at
least 5 inches of clearance above the tank. The unit should not be installed within 5 feet of
an Electronic Air Cleaner, 4-5 inch thick Media filters, or a UV Lamp.
Caution:
UV lamps
may destroy certain plastics/rubber unless shielding is applied to those surfaces.
DO NOT
install the Steam Humidifier on a Down-flow HVAC system.
Avoid
Fiberglass Duct-Board as
it cannot support the weight of the Steam unit when full of water.
DO NOT
install the Steam
Humidifier in an attic or crawl space exposed to freezing temperatures.
Figure 13.
Remember to insulate the water tank with the supplied insulation
wrap. Under extreme velocities it may be necessary to double
wrap the tank and/or the tank flange to prevent excessive heat
loss. Also remember to use gasket material on the duct opening
to prevent metal to metal heat loss and to prevent against
condensation and air leakage. On under-duct applications, it may
be necessary to insert an Air-Ramp in the duct to induce the
steam out of the tank. Contact Technical Support for assistance.
