Adjustment
Loosen the two screws located on the top side of the divider.
Slide the top part of the divider toward the outside until the
sealing strip makes contact with the outdoor louver. Tighten
the divider screws to complete the adjustment.
NOTE:
Let the caulk cure completely before installing the
chassis. This completes the plenum installation.
Condensate Disposal Preparation
for 9000 / 12000 / 18000 Models ONLY
IMPORTANT: This step must be performed to ensure that
the chassis installs and seals properly in the wall plenum.
If provisions for condensate disposal are made prior to
chassis installation and the drain is to be located beneath
the platform for the unit, use the accompanying drawing as
a guide for cutout locations. Only one drain per unit is
required.
Condensate Disposal System
The Condensate Disposal System increases energy
efficiency utilizing a factory installed fan that sling the cold
condensate onto the hot outdoor coil.
When high outdoor humidity prevents the slinger from
disposing of all the condensate, the excess condensate
overflows into the condensate drain pan and out of the ¾”
internal drain connections.
NOTE: If the Condensate Disposal System fails to remove
all of the condensate from the unit, any excess condensate
will overflow from a spillway in the rear of the unit directly
into the wall plenum, and drain outside the building. This is
your indication that the chassis or drain requires servicing.

6) A field supplied drain system must now be installed to
the slip end of the union. A trap is recommended and
drain connections should be connected to building
DWV system.
7) Pitch the drain line on a ¼” downward slope for every
foot (1’) of lateral horizontal run to the DWV.
8) The remaining two connections must be plugged using
the two ¾” pipe plugs (provided) and field supplied
teflon tape or pipe join compound. Hand-tighten to
prevent damage to unit or fittings.
9) Do not thread metal or copper pipe fittings directly into
unit.
10) Check system for leaks.
11) Failure to follow these procedures may result in
serious property damage.
12) A field supplied secondary condensate pan may be
required. Check with local codes.

Indoor Return Air Grille Installation
There are two Indoor Return Air Grille options as shown in
Figure 12. Choose the option that best suits your needs.
Use the installation instructions provided with accessories
for installation details.
Figure 12
Return Air Grille Options
NOTE: All Vert-I-Pak chassis are shipped with a 20” x
14” filter installed. If an accessory filter holder is to be
used, you MUST remove the factory shipped filter from
the chassis. Do NOT use two filters.
Option 1
VPRG4 Return Air Grille
with Access Panel
A field-supplied (25” x 20”) filter is
mounted inside the hinged access
door.
Kit contains hinge bracket for
mounting the door with the return
air openings high or low on the
door for optimal sound attenuation.
It is recommended to install the
door with the hinge on the right
side and the return air openings
high on the door.
Option 2
Field Supplied
Return Air Grille
Must have a minimum of 250
square inches of free area.
NOTES:
There are the Friedrich recommended return air
grille/filter/access panel arrangements. Consult
Friedrich on other arrangements. Improper return air
arrangements will cause performance problems.
Return air arrangements are shown from the front,
but can also be installed from the right or left side of
the unit.
Ductwork
The supply duct system should be designed via a recognized
method such as the equal friction method, or velocity reduction
method, using the appropriate duct calculator(s) for the type(s)
of duct (i.e. metal duct, duct board, or flex duct) being used in
the system. The duct system should be designed for a
maximum friction rate of .30" water column taking into consideration all fittings, registers and/or diffusers. DO NOT operate
unit without a supply duct attached.
The return air to Vert-I-Pak "A" series units MUST NOT be
ducted, and all units MUST have a free return air configuration
to perform properly.
WARNING
CAUTION
Moving parts hazard
Turn off electric power before servicing
this component.
Fan can start automatically.
Failure to do so can result in property
damage, personal Injury and/or death.
Indoor Air Flow Data
Indoor air flow may be determined by measuring the external static pressure (ESP) of the duct system using an
inclined manometer or magnehelic gauge, then consulting
chart “A” to determine actual air flow. Rated air flow for
each unit is obtained at .10” W.C. when operating with a
clean filter and a dry coil (i.e. heating) on the indicated
speed at 230 Volts. Use the air flow correction multipliers
contained in chart “B” to determine accurate air flow under
the listed conditions. Under no circumstances should the
Vert-I-Pak equipment be operated at an external static
pressure in excess of .30” W.C. Operation of the Vert-I-Pak
under these conditions will result in inadequate air flow
leading to poor performance and/or premature component
failure.
For LOW speed operation, connect the fan output terminal
from the thermostat to the GL terminal of the electronic
control. For HIGH speed operation, connect the fan output
terminal from the thermostat to the GH terminal of the
electronic control. For thermostats with two-speed fan
capabilities, connect the LOW speed output to the GL
terminal, and the HIGH speed output to the GH terminal.

Desk Control Terminals
The Friedrich VERT-I-PAK has built-in provisions for connection to an external switch to control power to the unit. The
switch can be a central desk control system or even a normally open door switch.
For desk control operation, connect one side of the switch to
the D1 terminal and the other to the D2 terminal (See figure
15). Whenever the switch closes, the unit operation will stop.
NOTE: The desk control system and switches must be
field supplied.
Maximum Wire Length for Desk Control Switch
Wire Size Maximum Length
#24 400 ft.
#22 600 ft.
#20 900 ft.
#18 1500 ft.
#16 2000 ft.
NOTE: It is the installer’s responsibility to ensure that all control
wiring connections are made in accordance with the installation
instructions. Improper connection of the thermostat control
wiring and/or tampering with the unit’s internal wiring can void
the equipment warranty and may result in property damage,
personal injury or death. Other manufacturer’s units and even
older Friedrich models may have different control wiring
connections. Questions concerning proper connections to the
unit should be directed to the factory.

Auxiliary Fan Control
The Smart Center also has the ability to control a 24VAC relay
to activate an auxiliary, or transfer, fan. The outputs are listed
as F1 and F2 on the control board.
To connect the relay, simply wire one side of the relay to F1
and the other side to F2. Anytime that the fan runs, the
terminals will send a 24VAC signal to the relay. The relay must
be 24VAC, 50mA or less.
NOTE: The relay and auxiliary fans must be field supplied.

chassis or operating the chassis.
Present the owner or operator of the equipment with the
Installation & Operation Manual, all accessory installation
instructions, and the name, address and telephone number
of the Authorized Friedrich Warranty Service Company in
the area for future reference if necessary.
Chassis Operation
Fresh Air Door
The Fresh Air Door is an “intake” system. The fresh air door
is opened via a slide on the front of the chassis located just
above the indoor coil. Move the slide left to open and right to
close the fresh air door. The system is capable of up to 60
CFM of fresh air at .3 H20 internal static pressure.
WARNING
Electrical Shock Hazard
Pull out electrical disconnect on front of
the chassis and turn off all power to the
unit before servicing.
Failure to do so can result in property
damage, personal injury and/or death.
Final Installation Checklist
Inspect and ensure that all components and accessories have been installed properly and that they have
not been damaged during the installation process.
Ensure that all installation instructions concerning
clearances around the unit have been adhered to.
Check to ensure that the unit air filter, indoor coil, and
outdoor coil are free from any obstructions.
Ensure that the circuit breaker(s) or fuse(s) and supply
circuit wire size have been sized correctly.
Check the condensate water drain(s) to ensure that
they are adequate for the removal of condensate
water, and that they meet approval of the end user.
Low Ambient Compressor Cut Out
Each chassis is equipped with low ambient protection in the
form of a thermistor, which will prevent compressor operation at low suction temperature.
oom Freeze Protection
R
Units are shipped from the factory with the room freeze
protection disabled. Room Freeze Protection can be
switched on at the owner’s preference by moving Dip Switch
6 to ‘ON’. This feature will monitor the indoor room
conditions and in the event that the room falls below 40ºF
the unit will cycle on high fan with the electric heater. This
occurs regardless of mode.
Emergency Heat Operation
In the event of a compressor failure in heat pump mode the
compressor may be locked out to provide heat through the
resistance heater. This feature ensures that even in the
unlikely event of a compressor failure the room temperature
can be maintained until the compressor can be serviced.
Moving dip switch 7 to ‘ON’ controls the emergency heat
setting.
Ensure that the entire installation is in compliance with
all applicable national and local codes and ordinances
having jurisdiction.
Secure all access panels (i.e. front cover and/or control
box), apply power to the unit, then start the unit, and
check for proper operation in each mode. Instruct the
owner or operator regarding the unit’s operation, and
the recommended routine maintenance schedule.
NOTE: Maintaining a log for recording the dates of maintenance and/or service is recommended, and should be
suggested to the owner or operator of the equipment.

WARNING
Electrical Shock Hazard
Pull out electrical disconnect on front of
the chassis and turn off all power to unit
before servicing.
Failure to do so can result in property
damage, personal injury and/or death.
Routine Maintenance
Performing Routine Maintenance
With the proper maintenance and care, your system will
operate ecomomically and dependably. Maintenance can be
accomplished easily by referring to the following directions.
However, before performing any maintenance, see above
stated WARNING.
CAUTION
Cut/Sever Hazard
Some edges may be sharp, use gloves
or other hand protection when handling
unit.
Failure to do so can result in minor to
moderate personal injury.
Replace Air Filter
A dirty air filter reduces the efficiency of your Vert-I-Pak and
allows lint and dirt to accumulate on the indoor-air coil. Lint
and dirt on the indoor-air coil can damage your unit.
The air filter should be replaced as it becomes dirty.
To replace the filter (chassis mounted return air filter):
1. Slide the filter clear of the filter rails.
2. Remove the filter.
3. Install new disposable filter.
NOTE:
FILTER IN PLACE OR BLOCK THE FRONT OF THE UNIT

DO NOT OPERATE YOUR SYSTEM WITHOUT A
Inspect and Clean Indoor-air Coil
Eventually, minor amounts of lint and dirt may pass through
the filter and collect on the indoor-air. These minor
accumulations can be carefully vacuumed away with a
brush attachment on a vacuum claner. Care must be taken
to avoid bending the aluminum finns on the coil. Bent fins
should be straightened using a special fin tool avalable from
most HVAC supply depots.
In
spect Outdoor-Ai r (OA) Intake and Exhaust
The unit’s outdoor-air intake and outdoor-air exhaust paths
must remain clear. Check the OA exhaust frequently. Keep
it free of all debris, snow, or ice. The OA intake should also
be kept free of obstructions. Blocking the OA exhaust or OA
intake opening will reduce the efficiency of your unit and
could damage it.
Inspect and Clean Condensate Drain
The condensate drain must be routed to a suitable drainage
area. Check the unit condensate drain periodically. Keep it
free of anything that may block or impede the flow of
condensate water. If there is any accumulation of foreign
matter in the drain pipe, it should be removed and cleaned.
The entire drain line must be protected from freezing.
Warranty
All warranty service work must be done by an authorized
servicer. See Product Warranty, and consult your dealer or
contractor for details.
