WARNING
Moving parts hazard
Turn off electric power before servicing
this component.
Fan can start automatically.
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. Rated air flow for
each unit is obtained at .10" W.C. when operating with a
clean filter and a dry coil (i.e. heating) on the indicated
speed at 230 Volts. Use the air flow correction multipliers
contained in chart "B" to determine accurate air flow under
the listed conditions. Under no circumstances should the
Vert-I-Pak equipment be 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.

Chassis Installation

Install the following components
A. Ensure that the wall plenum is installed in accordance
with the instructions listed on Pages 6-10.
B. Place the chassis into the closet with the outdoor side
facing the wall plenum opening.
C. Slide the chassis into the wall plenum until the plenum
divider seal is established. (See Figure 13)
Figure 13
Chassis Installation/
Installed View
The Vert-I-Pak chassis must be inserted into the wall
High
plenum so that the plenum divider gasket makes

CAUTION
Excessive Weight Hazard
Use two or more people when installing
your air conditioner.
Failure to so can resut in back or other
injury.
CAUTION
Cut/Sever Hazard
Some edges may be sharp, use gloves
or other hand protection when handling
unit.
Failure to do so can result in minor to
moderate personal injury.
