Indoor Airflow Data; Chassis Installation - Friedrich VERT-I-PAK A-Series Installation & Operation Manual

The Vert-I-Pak A series units must be installed with a free
return air configuration. The table below lists the indoor
airflow at corresponding static pressures. All units are rarted
at low speed.
The Vert-I-Pak units are designed for either single speed or
two fan speed operation. For single speed operation refer to
the airflow table below and select the most appropriate CFM
based on the ESP level. Connect the fan output from the
thermostat to the unit on either the GL terminal for low speed
or to the GH terminal for high speed operation.
For thermostats with two-speed fan outputs connect the low
speed output to the unit GL terminal and the high speed
output to the GH terminal.

For single speed thermostats connect to the GL terminal for Low
speed or GH terminal for High speed. Two speed control
thermostats will use both.

The Vert-I-Pak chassis must be inserted into the wall plenum so that the plenum divider gasket makes
contact with the condenser baffel in the unit.The chassis will fit approximately 2 3/8" into the wall plenum.
NOTE: Prior to installing the chassis, ensure that the drain pan and line arefree from debris.

Chassis Installation

NOTE: Prior to installing the chassis, ensure that the drain
pan and line are free from debris.
A. Ensure that the wall plenum is installed in accordance
with the VPAWP1-8/1-14 Installation Manual.
B. Ensure that the VPDP1 drain pan is installed correctly
(see page 9). Using the 3/4" plugs supplied with the
pan, plug the unused condensate drain hole. Connect a
drain to the condensate exit location. Be sure to use
teflon tape or approved pipe sealant on all drain
connections and plugs (see page 9).
C. Place the chassis into the closet with the outdoor side
facing the wall plenum opening.
D. Slide the chassis into the wall plenum until the plenum
divider seal is established and the factory-installed
chassis to plenum gasket has sealed to the top flange of
the plenum. (See Figure 8)
