Indoor air ow may be determined by measuring the external static pressure (ESP) of the duct system using an inclined
manometer or magnahelic gauge and consulting the above chart to derive actual air ow. Under no circumstances
should the small chassis Vert-I-Pak equipment be operated at an external static pressure in excess of .3” W.C. Operation
of the Vert-I-Pak under these conditions will result in inadequate air ow, leading to poor performance and/or premature
component failure.
Control
For LOW speed only operation, connect the fan output terminal from the thermostat to the GL terminal of the electronic
control.
For HIGH speed only operation, connect the fan output terminal from the thermostat to the GH terminal of the electronic
control.
For thermostats with two-speed capability, connect the LOW speed output to the GL terminal and the HIGH speed output
to the GH terminal.

Building Exterior Unit Opening Requirements
VPAK units must be installed on an outside wall. Conned spaces and/or covered areas should be avoided. Units must
be installed no closer than 12” apart when two units are side by side. If three or more units are to operate next to one
another, maintain a minimum of 60” between units or pairs of units (Figure B). If more than two units are sharing a oor
with adjacent, outset units, a minimum distance of 64” must be kept between units (Figure C). Also, a vertical clearance of
60” must be maintained (Figure A) between units. Units installed on the bottom oor must be mounted at least 6” off of the
ground.
Grill Clearance Requirements
Where obstructions are present use the
following guidelines for proper spacing from
the VPAK exterior louvered grill. Friedrich
recommends that ALL obstructions are a
minimum of 72” from the exhaust.
For minor obstruction(s) such as lamp poles
or small shrubbery, a clearance of 24” from
the outdoor louver must be maintained.
For major obstructions such as a solid
fence, wall, or other heat rejecting devices
like a condensing unit, a minimum distance
of 72” must be kept.

Primary Drain Installation
NOTE: Failure to follow the following procedures may result in serious property damage. A eld supplied secondary con-
densate pan or P-trap may be required. Check with local codes. In case of drainage system blockage, the unit base will
allow excess water to ow out of the unit through the plenum and the architectural louver. It is critical to ensure that the
drainage path is not blocked or obstructed in any way during installation.
1. The supplied drain kit must be connected to one of the three (left, right or rear) 3/4” FPT connections on the unit
base pan. Use of rear tting without connection to DWV system (drain, waste, vent) may result in staining
of the outside wall.
2. Insert the provided 3/4” nipple into the determined connection using eld-supplied Teon tape or pipe joint
compound.
3. With the slip end of a 3/4” union, connect to the nipple with Teon tape or pipe joint compound.
4. Hand-tighten all ttings to prevent damage to unit or ttings.
5. Install a eld-supplied drain system to the slip end of the union. A trap is recommended and drain connections
should be connected to building DWV system. Pitch the drain line of a 1/4” downward slope for every foot (1’) of
lateral horizontal run to the DWV.
6. Plug the two unused connection ports with the two provided 3/4” pipe plugs with eld-supplied Teon tape or
pipe joint compound. Hand tighten to prevent damage to the unit or ttings. Do not thread metal or copper pipe
ttings directly into unit.
7. Check the system for leaks.
