DO NOT make more than one turn with the duct and the ductwork should not
be longer than 3 feet in total, unless rigid ducting is used - see ‘

3)
DO NOT crush the vinyl Pipe.
4)
DO NOT install the unit next to a replenishment air supply.
5)
DO NOT install the unit within 8 feet of a heat source (Radiator, heater, etc…)
Warning!!!
Combustion Appliance Present in Dwelling
Read this Section Carefully
With the presence of appliances evacuating air outside the building envelope (such as range hood,
bathroom fan, dryer, Humidex, etc.) a negative pressure could be created inside the building. As the
pressure inside the building gets lower than the barometric pressure outside, the smoke and gases
from any combustion appliance (oil furnace, gas/wood stove, fireplace, etc.)
may be drawn into the
building rather than go out the chimney.
This problem is usually curable by setting the controls of exhaust appliances, including the Humidex
at less than maximum speed during the heating season (Note: when humidity conditions in the home
are below the humidity setting on the Humidex, as they usually are during the heating season, the
Humidex operates at approx. 25% of the capacity of a standard bathroom fan), or by introducing
make-up air inside the building. A fresh air kit (Air Supply Ventilator) is available from your Humidex
dealer, to help relieve the effects of negative air pressure in the building.
Ideal location of the Unit
-
Air drawn in by Humidex pulls moisture off the surface floors and walls. To maximize the
effectiveness;
A)
Install unit in dampest, coolest and lowest part of basement.
B)
If possible, without hindering point “A”, install the Humidex as far away as possible from
the source of replenishment air (i.e. stairwell) from upstairs or from replenishment air grill in
crawl space area. This will allow for the unit to draw in the maximum moisture across the
greatest surface distance before the upstairs replenishment air is pulled into the unit.
-
Keep away from sources of excess heat (i.e. furnace room).
-
Unit must be installed all the way down to floor level, in order to draw in the moisture.
It
should be approx. 3” and must not be higher than a max of 6” off floor level.
-
Keep at least 8 feet away from furnace or combustion appliance to reduce risk of interference
