Location and Mounting
H1008A,D Automatic Humidity Control
IMPORTANT
Do not install H1008 on supply air. Temperatures
in excess of 120°F cause the control to go into
error mode. If mounting near an elbow area,
keep the control 6 in. (152 mm) upstream from
the elbow so the humidity and temperature sen-
sor is exposed to the normal airflow (Fig.1).
Locate the control at least 12 in. (305 mm) upstream from
the humidifier (or dehumidifier/ventilator supply air) in the
return air duct where it can be exposed to the air stream
of the return air. See Fig. 1.
Fig. 1. Select duct location for control.
Use the following procedure to mount the H1008A,D in
the return air duct:
1.
Î
emove the cover by placing your thumb in the bot-
tom notch between the cover and the base and pull-

NOTE:
Be sure the sheet metal surface is flat after
drilling and cutting holes.
