Congratulations!
The Friedrich VPAK has been carefully engineered and manufactured to provide many years of dependable, efcient operation
while maintaining a comfortable temperature and humidity level. Many extra features have been built into the unit to ensure
quiet operation, optimal circulation of cool, dry air, and the most economic operation.
Please carefully read and follow the installation instructions and safety warnings detailed in this manual.
Refrigeration system under high pressure. Do not punc-
ture, heat, expose to ame or incinerate. Only certied
refrigeration technicians should service this equipment.
R410A systems operate at higher pressures than R22
equipment. Appropriate safe service and handling prac-
tices must be used. Only use gauge sets designed for use
with R410A. Do not use R22 gauge sets. Failure to do so
can result in property damage, personal injury, or death.
WARNING
Please read this manual thoroughly prior to equipment
installation or operation. It is the installer’s responsibility
to properly apply and install the equipment. Installation
must be in conformance with the NFPA 70-2008 National
Electric Code or current edition, International Mechanic
code 2009 or current edition and any other applicable local
or national codes.
Your safety and the safety of others are very
important.
We have provided many important safety messages in
this manual and on your appliance. Always read and
obey all safety messages.
This is the safety alert symbol.
This symbol alerts you to potential
hazards that can kill or hurt you
and others.
All safety messages will follow the
safety alert symbol with the word
“WARNING” or “CAUTION”.
These words mean:
Indicates a hazard which, if not avoided, can result in
severe personal injury or death and damage to product or
other property.
Indicates a hazard which, if not avoided, can result in
personal injury and damage to product or other property.
All safety messages will tell you how to reduce the chance
of injury, and tell you what will happen if the instructions
are not followed.
Indicates property damage can occur if instructions
are not followed.

Electrical Data and Specications
Electrical Requirements
Wire Size Use ONLY wire size recommended for
single outlet branch circuit.
Fuse/Circuit
Breaker
Use ONLY type and size fuse or HACR cir-
cuit breaker indicated on unit’s rating guide.
Proper over current protection to the units is
the responsibility of the owner.
Grounding Unit MUST be grounded from branch circuit
to unit, or through separate ground wire
provided on permanently connected units.
Ensure that branch circuit or general pur-
pose outlet is grounded.
Wire Sizing Use recommended wire size given in tables
and install a single branch circuit. All wiring
must comply with local and national codes.
NOTE: Use copper conductors only.
Electrical Rating Table
NOTE: Use copper conductors ONLY. Wire sizes are per NEC.

** Based on 100’ or less of copper, single insulated conductor at 60˚ C
NOTE: All 230/208 chassis must be hard wired with a properly sized breaker. See unit nameplate for specic electrical requirements.
Use HACR type breakers to avoid nuisance trips. All eld wiring must be done in accordance with NEC and local codes. It is the in-
staller’s responsibility to ensure that the electrical codes are met.
WARNING
Electrical Shock Hazard.
Turn OFF electric power before service or instal-
lation.

Unit must have correct fuse or circuit breaker pro-
tection. Unit’s supply circuit must have the correct
wire conductor size. All electrical connections and

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.
