Failure to do so can result in property
damage, personal Injury and/or death.

Indoor Air Flow Data

Indoor air flow may be determined by measuring the exter-
nal static pressure (ESP) of the duct system using an
inclined manometer or magnehelic gauge, then consulting
chart "A" to determine actual air flow.
correction multipliers contained in chart "B" to determine
accurate air flow under the listed conditions.
circumstances should
operated at an external static pressure in excess of .30"
W.C. Operation of the Vert-I-Pak under these conditions
will result in inadequate air flow leading to poor
performance and/or premature component failure.
For LOW speed operation, connect the fan output terminal
from the thermostat to the GL terminal of the electronic
control. For HIGH speed operation, connect the fan output
terminal from the thermostat to the GH terminal of the
electronic control. For thermostats with two-speed fan
capabilities, connect the LOW speed output to the GL
terminal, and the HIGH speed output to the GH terminal.
