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 70-2002 National Electric Code or current edition
and Universal Mechanical Code current edition and applicable local or national codes.
Proper installation is not difcult, but it is essential.

Vert-I-Pak Installation Recommendations
For proper unit performance and maximum operating life please refer to the minimum installation clearances below.
The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for information
regarding affects of other installation arrangements.
By following these simple recommendations you can be condent that your Friedrich Vert-I-Pak® will provide years of worry-free
operation.
Figure 2
Figure 1
Any time obstructions are present
use the following guidelines for proper
spacing from the VERT-I-PAK louver:
• For minor obstructions such as lamp
poles or small shrubbery a clearance
of 24" from the outdoor louver should
be maintained.
• For major obstructions such as a solid
fence, wall or other heat rejecting
device like a condensing unit, a mini-
mum distance of 72" should be kept.

units must be installed on an outside wall. Conned spaces and/or covered areas should be
avoided. Units should be installed no closer than 12" apart when two units are side by side. If three of more
units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical
clearance of 60" should be maintained between units. Units installed on the bottom oor should be mounted
at least 6" off of the ground.

Chassis Specications
Important: all 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specic chassis
electrical requirements. See page 8 - Figure 5 for unit wiring and wall thermostat wiring. See page 8 for wire size. Use
HACR type breakers to avoid nuisance trips. All eld wiring must be done in accordance with nec and local codes.

5
920-075-09
Note: All eld wiring must comply with NEC and local codes. It is the responsibility of the installer to insure that the electrical codes are met.
Electrical Requirements
Wire Size Use O NLY wiring size recommended for single outlet branch circuit.
Fuse/Circuit Breaker Use ON LY type and size fuse or HACR circuit breaker indicated on unit's rating plate (See sample on next page). Proper current
protection to the unit 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.
Be sure that branch circuit or general purpose 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.
CAUTION
Electric shock hazard.
Turn OFF electric power before service or installation.
All electrical connections and wiring MUST be installed by a qualied electrician and
conform to the National Electrical Code and all local codes which have jurisdiction.
Failure to do so can result in property damage, personal injury and/or death.
All 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specic chassis electri-
cal requirements. See gure 8 for unit wiring and wall thermostat wiring. See page 7 for wire size. Use HACR
type breakers to avoid nuisance trips. All eld wiring must be done in accordance with NEC and local codes.

• Rough opening dimension 24 5/8" wide x 30 7/8" high.
• Ensure that the bottom of the plenum is 1 1/2" from the oor of the closet. Note: 9,000 / 12,000 / 18,000 installation
height may be different. Refer to specic installation manual for clarication.
• For proper airow, maintain a minimum distance of 12" between Vert-I-Pak units. Consult the factory for any
installation or application questions.
IMPORTANT REMINDER: FRIEDRICH WALL PLENUM IS NOT DESIGNED TO CARRY
STRUCTURAL LOADS. PROPER WALL HEADER CONSTRUCTION IS REQUIRED. THE PLENUM
REQUIRES PROPER FLASHING, SHIM AND CAULK FOR A WEATHER RESISTANT INSTALLATION.

Notes:
A. These are the Friedrich recommended return air grille/
lter /access panel arrangements. Consult the factory on
other arrangements. Improper return air arrangements
will cause performance problems.
B. Return air arrangements are shown from the front, but
can also be installed from the right or left side of the unit.
Drain Pan Installation
Condensate Disposal System
The VPDP1 drain pan features two ¾ female PVC ttings to at-
tach a drain connection to on the left or right side of the drain pan.
Condensate piping can be routed to the left, right or beneath the
unit platform. See drain pan installation manual for more information.
Part 1: The system’s rst stage increases energy efciency
utilizing a factory installed fan that slings the cold
condensate onto the hot outdoor coil.
Part 2: When high outdoor humidity prevents the slinger
from disposing of all the condensate, the excess
condensate overows into the condensate drain pan
and out of the ¾" internal drain connections.
Part 3: If Parts 1 & 2 fail for any reason, excess condensate
overows from a spillway directly into the wall plenum
to the outside of the building. IF THIS OCCURS,
THIS IS A WARNING THAT THE CHASSIS OR
DRAIN NEEDS SERVICING.
Option 1

with Access Panel
A eld-supplied (25" x 20")

CAUTION
 The unit basepan has three (3) provisions (left, right,
and rear) for connecting an external condensate drain.
 A eld supplied condensate drain system must be
connected to one of the three (left, right, or rear) 3/4"
FPT connections on the unit basepan. Use of rear
tting may result in staining of the outside wall.
 The remaining two connections must be plugged
using the two 3/4" pipe plugs (provided) and eld
supplied teon tape or pipe joint compound.
 The addition of a secondary drain pan may be
required. Follow all applicable codes.
 Failure to follow these procedures may result in
serious property damage.
 A eld supplied secondary condensate pan may be
applied. Check with local codes.

Ductwork Preparation
Duct ESP:
To determine your system's indoor external static pressure (ESP,
in inches of water) use a duct calculator (as provided by your duct
supplier). Include all ex duct transitions and discharge grille(s).
If ex duct is used, be sure all the slack is pulled out of the ex
duct. Flex duct ESP can increase considerably when not fully
extended. DO NOT EXCEED a total of .30 ESP, as this is the
MAXIMUM design limit for the VERT-I-PAK A-Series unit.
Chassis Installation
Install the following components
A. Ensure that the wall plenum is installed in accordance
with the VPAWP1-8/1-14 Installation Manual.
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 9)
The Vert-I-Pak chassis must be inserted into the wall plenum so that the plenum divider gasket makes contact with the plastic condenser
bafe on the unit. The chassis will t approximately 23/8" into the wall plenum.

RT4 Digital Thermostat
Remote Thermostat and Low Voltage Control Connections
Remote Thermostat
All Friedrich Vert-I-Pak units units are factory congured to be
controlled by using a single stage remote wall mounted thermostat.
The thermostat may be auto or manual changeover as long as the
control conguration matches that of the Vert-I-Pak unit.
To control the unit with a wall-mounted thermostat:
1) Pull the disconnect switch.
2) Unscrew and remove the control box panel.
3) Run the wires through the top hole in the control box and
under the control components in the box to reach the
connection terminal for the wiring.
4) Make the wire connections, appropriately matching the
wires as the shown in the wiring diagram.
5) Once each wire is matched and connection the unit is
now controlled by the thermostat.
6) Reattach control box cover.
