The Vert-I-Pak was designed for installation in residential
and light commercial applications. These instructions detail
a typical method of installation. Figure 4 shows the typical
component location and airfl ow paths through the unit.
1) Indoor and Outdoor Air Requirements
The indoor and outdoor air systems are designed to operate
at specifi ed airfl ow rates and external static pressures. The
supply and return air duct system pressure losses (including fi lter,
louver/grille and registers) must not exceed the listed external
static pressures for either the indoor or outdoor air systems.
CAUTION:
Failure to adhere to indoor air and outdoor
air requirements as listed in the following sections will void
unit warranty.
A. Outdoor Air System
As a completely self-contained system, the Vert-I-Pak unit
requires an adequate supply of outdoor air to exchange heat

from the outdoor air coil. The outdoor air intake and discharge
openings are located on the back side of the unit. The unit may
be installed where the outdoor air path runs through the wall of
the building directly behind the unit or where the outdoor air
intake and discharge paths are ducted separately away from
the unit. Figure 9 shows two typical ducted OA designs.
CAUTION:
To ensure proper operation, the outdoor
air intake and discharge air paths must be free and
unobstructed The two air paths must be situated to ensure
that the intake and discharge air do not recirculate (also
called short-circuit).
B. Ducted Condenser Air
For ducted outside air applications, the combined pressure
losses of the intake and discharge air paths must not exceed
the external static capabilities of the system at the design
airfl ow (See Table 1).
