INTRODUCTION

Most any air conditioner will keep you cool. Our air conditioner was designed to
do it effi ciently. Effi ciency means less cost to you while keeping you comfortable.
The P3BD Series single packaged air conditioners are self contained cooling
units that use the existing furnace to provide airfl ow and can be installed on a
slab. P3BD series equipment can only be used with the following NORDYNE
furnaces: E3EX*, M3RX* to achieve 13 SEER effi ciency levels. Units are ETL
and ETLc listed.

WHY YOUR AIR CONDITIONER WORKS SO WELL, SO QUIETLY

1. Air is cooled by a large evaporator coil. Moisture is also removed from the air by
this same coil.

2. Air is then delivered through the main duct, via registers, into your home.

3. Return air is drawn through the return grille.

4. This air enters the unit, passes through the evaporator coil, is cooled and dehumidi­fi ed. Then the cycle begins again.

OPERATING INSTRUCTIONS

To Turn On Air Conditioner

1. Set the system switch to “Cool.”

2. Set the thermostat at the temperature level
you desire.

3. Your air conditioner should start as soon as
room temperature rises above the setting
on the thermostat.

3. For best air fl ow, make sure your return
grille is not covered and that the fi lter is
clean.

4. Check the outdoor condenser coil and make
sure it is clean and not clogged with grass
or leaves.

If your air conditioner still isn’t working, call your
nearest distributor.

SECTION 2. INSTALLER
INFORMATION

To Shut Off Air Conditioner

1. Turn the system switch to “Heat” or “Off.”

2. Turn the thermostat to the desired heating
temperature setting.

BEFORE YOU CALL A SERVICEMAN

Check your system at the start of each air con­ditioning season. Make sure it’s working right,
clean or change fi lters and make any needed
adjustments.

In addition, follow these simple rules:

1. Never run your system without a fi lter. If you
do, the cooling coils will collect dirt and may
become clogged.

2. Set your thermostat at the comfort level you
wish -- and then leave it alone. Let it control
the operation of the air conditioning system.
If you get chilly, turn it up a degree at a time
until comfort is restored.

3. It takes longer for an air conditioner to cool
your dwelling than it does for your furnace
to heat it. So . . . don’t turn the unit on and
expect a dramatic drop in temperature, at
least not right away. If your home is hot and
humid, the temperature will drop slowly.

4. Check your fi lters every 30 days in summer
to see if they are dirty. To keep them clean,
use a mild solution of detergent and water
on washable types. Replace non washable
fi lters.

5. Keep your outdoor condenser coil clean.
You can hose it down when it gets dirty.

If your air conditioner isn’t working:

1. Make sure the fuses are not blown or that
your circuit breakers are on.

2. See that your thermostat is set at the
desired temperature and that your system’s
switch is on “Cool.”

GENERAL

Read the following instructions completely
before performing the installation.

These instructions are for the use of qualifi ed
personnel specially trained and experienced
in the installation of this type of equipment
and related system components. Some states
require installation and service personnel to
be licensed. Unqualifi ed individuals should not
attempt to interpret these instructions or install
this equipment.

The single packaged air conditioners are de­signed for outdoor installation only and can be
readily connected into the high static duct system
of a home. The only connections needed for
installation are the supply and return ducts, the
line voltage, and thermostat wiring.

The single package air conditioner is completely
assembled, factory wired, and factory run tested.
The units are ready for easy and immediate
installation.

PRE-INSTALLATION CHECK

Before any installation is attempted, the cool­ing load of the area to be conditioned must be
calculated and a system of the proper capacity
selected. It is recommended that the area to
be conditioned be completely insulated and
vapor sealed.

The installer should comply with all local codes
and regulations which govern the installation
of this type of equipment. Local codes and
regulations take precedence over any recom­mendations contained in these instructions.
Consult local building codes and the National
Electrical Code (ANSI CI) for special installation
requirements.

The electrical supply should be checked to de­termine if adequate power is available. If there
is any question concerning the power supply,
contact the local power company.

Inspecting Equipment: All units are securely
packed at the time of shipment and, upon arrival,
should be carefully inspected for damage. Claims
for damage (apparent or concealed) should be
fi led immediately with the carrier.

INSTALLATION

CAUTION:

Do not tip the unit on its side. Oil
may enter the compressor cylinders
and cause starting trouble. If unit has
been set on its side, restore to upright
position and do not run for several
hours. Then run unit for a few seconds.
Do this three or four times with fi ve
minutes between runs.
