Section III – Installation
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
s u p p l y a n d r e t u r n a i r d u c t s y s t e m p r e s s u r e l o s s e s ( i n c l u d i n g 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).

C. Indoor-Air (Conditioned Supply Air) System
920-164-02 (10-04)
The VEB/ VHB series unit may be applied in either a free return
air confi guration or a ducted return air confi guration. The supply
air path is intended to be ducted. The design and construction
of the indoor-air system must provide adequate air distribution
to ensure comfort levels throughout the structure.
If the unit is installed in a closet behind a door and the return
air louver or grille is directly opposite the unit RA opening,
2-in. clearance is required between the front of the unit and
the back side of the louver or grille. If the louver or grille is
located elsewhere on the door so it is not directly in front of
the RA opening, a minimum of 7-in. clearance is required
The combined pressure losses of the return and supply air
paths must not exceed the external static capabilities of the
system at the design airfl ow (See Table 2 below).
between the front of the unit and the back side of the door.
The minimum "net free open area" required for the RA louver
or grille is listed in Table 2.

A. Thermostat Location
Locate the thermostat about 5 ft. above the fl oor
in an area with good circulation at average indoor
temperature.
Do not mount thermostat where it may be affected by:
• Drafts or dead-air spots behind doors and in
corners.
• Hot or cold air fl ow from ducts.
• Radiant heat from sun or appliances.
• Concealed pipes or chimneys.
• Unheated (uncooled) areas behind thermostat,
such as an outside wall.

B. Thermostat Mounting and Wiring
The thermostat is a precision instrument and was carefully
adjuste d at the fac tor y. Han dle it c areful ly.
CAUTION: Disconnect the power supply before begin-
ning installation of the thermostat to prevent electrical shock
or equipment damage. Do not short across the thermostat
terminals. This can burn out the thermostat anticipator.
All wiring for the thermostat circuit must comply with NEC,
state and local codes. Use No. 20 AWG color-coded, insulated
(35°C minimum) wire. If the thermostat is located more than
13
Page 14
920-164-02 (10-04)
100 ft. from the unit (as measured along the control voltage
wires), use No. 18 AWG color-coded wires to avoid excessive
voltage drop.
1. In replacement applications, check the existing thermostat wiring for cracked or frayed insulation. Replace
any wiring in poor condition. All wiring must comply
with local codes and ordinances.
2. Run wiring (if necessary) to the location. Connect the
wires to the terminals on the back of the thermostat.
(See Figure 11.)
3. Push the excess wire back through the hole and plug
any opening with packing material to prevent drafts that
may affect thermostat performance.
4. Loosely secure the thermostat to the wall with screws
through the two mounting holes in the middle of the
thermostat.
5. Level the thermostat. Tighten the two mounting
screws.
6. Replace the thermostat cover.

from freezing to prevent condensate from backing up in
unit during freezing outdoor conditions. See page 4 for
Cold Climate accessories.
NOTE: If the unit is to be installed in an attic or furred space
where damage may result from condensate overfl ow, it may
be necessary to provide a fi eld-supplied secondary drain
pan. Always refer to local and national codes.
Installation - Final Checklist
Is power to the unit ON?
Are circuit breakers/power disconnect inside
of the unit ON?
Is ductwork sealed for an airtight fi t?
Is the condensate drain line installed and run
to an appropriate disposal site.?
Is the thermostat level and properly installed?
Is the heat anticipator indicator set to the
correct setting?
4) Condensate Drain Line
The condensate drain exits the unit 2" above fl oor level at the
right side front corner of the unit.
Install a condensate drain line of the same size as the drain
fi tting on the unit. PVC plastic pipe (3/4 in. I.D.) makes an
ideal condensate line (if local codes allow).
Run condensate drain line from unit to fl oor drain or outside
perimeter of building per local codes.
The condensate line must have a minimum drop of 1/4" per
running foot as it leaves the unit. When a horizontal run of
15 ft. or longer is required, it may be necessary to install a
vent tee in the drain line near the unit or use a larger diameter

Section IV – Owner's Manual and Operating Information
Identifying Your System
Take the time to familiarize yourself with the type of system
you have. This knowledge will be of use in understanding the
basic operation of your unit.
A self-contained unit, like the Vert-I-Pak, has all of its major
components in one cabinet located inside your home. The
unit does not have a separate outdoor unit like a traditional
“split-system” air conditioner or heat pump. Figure 4 shows
the location of the major components inside the cabinet.
The product model and rating data label is affi xed to the unit
front panel and provides the necessar y information for specifi c
identifi cation of the unit. You should familiarize yourself with
the model and serial numbers listed on the label.
Important Facts
To better protect your investment and to eliminate unnecessar y
service calls, familiarize yourself with the following facts:
Your system should never be operated without a clean air
fi lter properly installed. A dirty, clogged air fi lter will increase
operating costs and shorten the life of the unit. The air fi lter
should be replaced as it becomes dirty.
Supply-air and return-air registers should not be blocked.
Restricted airfl ow reduces the effi ciency and life span of
your unit.
For your system to function properly, it MUST have a constant
supply of outdoor air to the outdoor air coil located inside the
unit. The outdoor-air intake and exhaust openings are located
on the back side of the unit. Familiarize yourself with the
outside air openings on the building and check to ensure that
they are not obstructed.
Thermostat
Your multipurpose indoor thermostat is the control center for
your comfort system. You should familiarize yourself with its
proper operation. Attempting to control the system by other
means – for instance, switching the electrical supply power
ON and OFF – may cause damage to the unit.
With some thermostats, increasing the HEAT mode temperature
set point more than 2°F may cause the auxiliary elec tric heaters
to operate to satisfy the call for heating. To minimize energy
costs, do not increase the HEAT mode temperature set point
by more than 2°F at a time.
Depending on the design of your home and its ventilation
ductwork and registers, areas of warm or cool air may develop
throughout the home. Operating the unit with the fan switch
“ON” increases air mixing throughout the home and reduces
temperature variations within the home.
Dehumidifi cation
During the cooling season, the Vert-I- Pak also dehumidifi es the
air in the home while is it cooling the air. After a few minutes of
operation, water should run freely from the condensate drain
line ex ten de d t o t he ou ts id e o f y ou r h om e. If condens ate is no t
running from the drain line, check to be sure that the drain hose
or pipe is properly connected to the drain fi tting located on the
bottom of the unit which is accessible from beneath the home.
Check the drain line periodically during the cooling season
to ensure the condensate is running freely from outside the
home and draining away from the home’s foundation. (Note:
in lower humidity climates, the indoor air may be too dry to
generate condensate during the cooling mode.)
Heat Pump
If you are a fi rst-time owner of an all-electric heat pump, the
operating characteristics of the system may be different than
you are accustomed to as compared to conventional electric
resistance, gas or oil furnaces. Air entering a conventional
furnace at 60°F may be warmed 60° to 100°F. The supply air
leaving the registers would then be between 120° and 160°F
depending on the system. A heat pump warms the same 60°F
air 20° to 30°F. The supply air leaving the registers would then
be between 80° and 90°F. This air may feel cool because it is
s l i g h t l y l e s s t h a n y o u r b o d y t e m p e r a t u r e . H o w e v e r , i t i s s u f fi ciently
warm to keep you comfortable and is adding heat to your home.
A heat pump will run for much longer periods of time than a
conventional furnace. This longer operational time is normal for
all heat pumps and is saving you energy in comparison to many
conventional furnaces. On days wit h outdoor temperatures below
40°F, it is normal for the heat pump to run for extended periods
of time and may be assisted by the auxiliary electric resistance
heating elements. Once you understand the operation of your
new heat pump, you will appreciate its constant, even heat and
lower energy consumption.
Heat Mode Operation
During the heat mode of operation, frost or ice may build up on
the outdoor-air coil after operating for extended periods during
15
Page 16
920-164-02 (10-04)
particularly cool and humid weather. When this occurs, your
heat pump senses this condition and goes through a defrost
cycle. During the defrost cycle, the outdoor-air blower is turned
off, and the reversing valve reverses the fl ow of refrigerant
through the outdoor-air coil so it is heated and the frost or ice
melts. You may notice the defrost cycle inside your home by a
faint click and hissing sound and a slight change in the sound
created by the blower as the defrost cycle begins and ends.
During the defrost cycle, you may also notice that the air is
quickly heated as the defrost cycle ends. Outside the home,
a cloud of water vapor created by the melting frost or ice may
be visible as it is exhausted. This is normal and keeps the unit
working effi ciently. Do not be alarmed!
Thermostat Operation
The operation of the system is controlled by the indoor
thermostat. Most thermostats have 3 controls: a temperature
control selector, a FAN control, and a SYSTEM or MODE
control. (See Figure 3.)
Typical Heat /Cool Thermostat
The temperature control is a selector or set of buttons that
allows you to establish the degree of temperature that you
w is h to ma int ai n f or yo ur pe rs on al c om fo rt . S om e t he rm o st at s
have two temperature control selectors: one for setting the
temperature desired during the cooling cycle, and one for
setting the heating operation temperature.
Typical settings are 78°F for cooling and 68°F for heating.
Fan Control
The FAN control offers t wo options for controlling t he indoor-air
blower: AUTO and ON. When the FAN control is set to AUTO,
the blower will operate only while the thermostat operates the
cooling or heating equipment. When the FAN control is set
to ON, the blower will operate continuously – regardless of
whether cooling or heating equipment is operating. This setting
allows for continuous air circulation and fi ltration.
System Control
The SYSTEM or MODE control on your thermostat offers
the following selections: COOL, OFF, HEAT, and EM HEAT.
Condensate
The heat pump may generate condensate during both the
cooling and heating modes of operation. For proper operation,
a condensate drain line must be extended from the drain fi tting
on the right side of the unit to the perimeter of the home or to
a proper drain location. The drain line must be sloped towards
the outside of the home or drain location and be protected
from freezing.
NOTE: In order for condensate to drain freely, the unit must
be installed level.
Neither the cooling nor heating equipment will operate when
the SYSTEM or MODE control is set to OFF. With the SYSTEM
or MODE control set to COOL, your unit will operate in cooling
mode. With the SYSTEM or MODE control set to HEAT, your
unit will operate in heating mode.
Auxiliary Heating
Your system also includes an auxiliary electric heating source.
The SYSTEM or MODE control options HEAT and EM
HEAT provide convenient selection between the two heating
appliances. The heat pump will operate when SYSTEM or
MODE control is set to HE AT. The auxiliar y electric heater may
also be used o n cold days to supplement heat pump heatin g.
With the SYSTEM or MODE control set to EM HEAT, the heat
pump is turned off and the auxiliary electric heat is activated.
The unit is now operating as an electric furnace.
On heat pump systems, the wall thermostat regulates the use
of auxiliary electric heat to maximize energy effi ciency and
your home comfort.
Cooling Cycle
When operating in the cooling cycle, your unit will operate
until the indoor temperature is lowered to the level you have
selected on the indoor thermostat. On ext remely hot days, your
unit will operate for longer periods of time and have shorter
“off” periods than on moderate days.
The following are typical conditions that add extra heat and/or
humidity to your home and force your cooling unit to work
longer to keep your home comfortable:
• Entrance doors are frequently opened and closed.
• Laundry appliances are being operated.
• A shower is running.
• More than usual number of people are present in the home.
• More than the normal number of electric lights are in use.
• Drapes or blinds are open on the sunny side of the
building or home.
16
Page 17
920-164-02 (10-04)
Heating Cycle
With the SYSTEM control of your indoor thermostat set to
HEAT, the heating section of your home comfort system will
operate until room temperature is raised to the level you have
selected. Of course, the heating unit will have to operate for
longer periods to maintain a comfor table environment on cooler
days and nights than on moderate ones. When the demand is
greater than the capacity of the heat pump alone, the auxiliary
electric heaters will supplement the heat pump.
Defrost Cycle
When your heat pump is providing heat to your home and the
outdoor temperature drops below 45°F, moisture may begin
to freeze on the surface of the outdoor-air coil. If allowed to
build up, this ice would impede airfl ow across the coil and
Performing Routine Maintenance
With the proper maintenance and care, your system will
operate economically and dependably. Maintenance can be
accomplished easily by referring to the following directions.
H o w e v e r, b e f o r e p e r f o r m i n g a n y m a i n t e n a n c e, c o n s i d e r t h e s e
important safety precautions:
WARNING: Elec trical Shock Hazard . Bef ore at tem pting
any service work or routine maintenance, turn off all electrical
connections to the unit. Failure to do so may result in property
damage, personal injury and/or death.
CAUTION: A l t h o u g h g r e a t c a r e h a s b e e n t a k e n t o m i n i m i z e
sharp edges in the construction of your unit, be extremely
careful when handling parts or reaching into the unit.
Replace Air Filter
A dirty air fi lter reduces the effi ciency 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 and void the
warranty. The air fi lter should be replaced as it becomes dirty.
To replace the fi lter (front air return units):
1. Slide the fi lter to the right until it clears the fi lter rails
(See Figure 12).
2. Remove the fi lter.
3. Install new disposable fi lter.
CAUTION: Do not operate your system without a fi lter
in place, nor block the front of the unit return air opening.
reduce the amount of heat absorbed from outside air. To
maintain energy-effi cient operation, your heat pump has an
automatic defrost cycle.
The defrost cycle will occur only if ice is suffi cient to interfere
with normal heating operation. After ice is melted from the
outdoor-air coil, the unit automatically switches back to normal
heating mode.
Do not be alarmed if steam or fog appears at the outdoor-air
exhaust during the defrost cycle. Water vapor from the melting
ice may condense into a mist in the cold outdoor air.
NOTE: Non-Heat Pump models use a single stage heat
thermostat. When a demand for heat is made, these
units will use the electric heat strip heat immediately.
Inspect Outdoor-air 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 effi ciency of your unit, could
damage it, and void your warranty.
Inspect and Clean Condensate Drain
The condensate drain must be routed to a suitable drainage
area. Check the unit condensate drain periodic ally. Keep it free
of anything that may block or impede the fl ow of condensate
w at er. I f th er e i s a ny a c c um u l at i on o f fo re ig n m at t er i n t he d r ai n
pipe, it should be removed and cleaned. The entire drain line
must be protected from freezing.

Inspect and Clean Indoor-air Coil
Eventually, minor amounts of lint and dirt may pass through
the fi lter and collect on the indoor-air coil. These minor
accumulations can be carefully vacuumed away with a brush
attachment on a vacuum cleaner. Care must be taken to
avoid bending the aluminum fi ns on the coil. Bent fi ns should
be straightened using a special fi n tool available from most
HVAC service technicians.
