On your purchase of one of the most versatile comfort conditioning systems available in the air conditioning industry.
This Stealth series high efficiency system has been precision designed, manufactured of high quality materials and has
passed many vigorous inspections and tests to ensure years of satisfactory service.
This booklet is meant to increase your understanding of your system, tell you how to operate it efficiently and how to
obtain the greatest measure of comfort at the lowest operating expense. Please read this booklet thoroughly.
We appreciate your interest in our products and your decision to purchase our system. Enjoy your comfort.
Y2K COMPLIANCE
All York thermostats and system control
boards for the Stealth™ series are Y2K
compliant.
THERMOSTATS
YOUR KEY TO COMFORT
Though thermostats may vary widely in
appearance they are all designed to
perform the same basic function, to
control the operation of your air conditioning system. Regardless of size or
shape, each thermostat will feature a
temperature indicator; a dial, arm or
push button for selection of the desired
temperature; a fan switch to choose the
indoor fan operation; and a comfort
switch for you to select the system
mode of operation.
Your new Stealth unit will require a twostage thermostat for optimum efficiency
and energy savings. York has tested
and certified the Enerstat ® SMS-1 and
Honeywell ® T8624D as the best models
for your new comfort system. Please be
aware that many different thermostats
operate on batteries or “power stealing”
principals. York can not support such
models to be trouble free when used
with the Stealth series units.
The following illustrations and discussion will aid you to determine which type
of thermostat you have for your system.
A complete operating instruction is provided by the manufacturer for each thermostat. Familiarize yourself with its
proper operation to obtain the maxium
comfort with a minimum of energy consumption.

COOLING ONLY
If your air conditioning system is
designed to provide only cooling, with
no capability for heating operation, a
two-stage cooling only thermostat, with
a manual, two-position “Cool” and “Off”
comfort switch is all that is required for
system operation.
NOTE: If you have an independent
heating system (with a separate thermostat), always be sure the heating
control is turned “Off” before turning on
the cooling system.
COOLING AND HEATING
FIGURE 1: PROGRAMMABLE
ELECTRONIC THERMOSTAT
If your system has been designed to
allow both cooling and heating operation, you may have either a manual
change-over type, or a programmable
electronic type thermostat with 2-stages
of cooling and 2-stages of heat.
MANUAL CHANGE-OVER
Manual change-over simply means that
the comfort switch must be manually
positioned every time you wish to switch
from the cooling to heating or heating to
cooling modes of operation.
PROGRAMMABLE
ELECTRONIC
THERMOSTATS
The computerized electronic thermostat
is actually a sophisticated electronic
version of a manual change-over type.
This thermostat includes features which
allow “set-back” temperature variations
for periods of sleep, or while you are
away during the day, and means energy
savings for you. The thermostat also
features a digital clock.
FIGURE 2: PROGRAMMABLE
ELECTRONIC THERMOSTAT
FAN OPERATION SELECTION
A multi-position fan switch allows you to
choose the type of fan operation of the
indoor fan.
AUTO
With the thermostat fan switch set to
“AUTO”, the fan will run intermittently as
required for either heating or cooling.
This position will provide the lowest operating cost. If you purchased one the of
the York thermostats, they have an
Unitary Products Group

550.37-O4Y
Intelligent fan mode which continually
circulates the air during occupied
modes or when you are at home, and
can cycle the fan during unoccupied
mode or during the night while you
sleep to further conserve energy.
NOTE: if your cooling and heating temperature adjustments are separate, be
sure to set both.
ON
3. Move the comfort control switch to
the desired mode of operation (Cooling
or Heating) found on your particular
thermostat.
CONTINUOUS FAN OPERATION: With
the thermostat fan switch set to “ON”,
the indoor fan will not shut off. However,
the cooling and heating systems will still
operate as required by room temperatures. This provides continuous air filtering and more even temperature
distribution to all conditioned spaces.
FAN ONLY OPERATION: On moderate
days, usually during spring and fall,
when neither heating nor cooling is
required, you may want to run only the
fan to ventilate, circulate and filter the
air in your home or building. Set the
comfort control switch to “OFF” and the
fan switch to “ON”. Be sure to return the
switches to their original positions for
normal operation.
START-UP
Do not operate this unit
when outdoor temperatures
are below 60°F as this will
cause damage to the unit.
The comfort control switch is assumed
to be in the “OFF” position. If the main
power supply to the outdoor and indoor
units is off, turn the appropriate disconnects to the “ON” position. Place the
system into operation as follows:
1. Set temperature adjustment to the
desired temperature on your thermostat.
COOLING - The higher the setting, the
lower the amount of energy consumed.
The National Bureau of Standards reccommends a setting of 78 °F.
HEATING - The lower the setting, the
lower the amount of energy consumed.
Federal guidelines recommend a setting of 65 °F or lower.

2. After considering “Fan Operation
Selection” above, select and set the fan
operation mode you desire.
POWER FAILURE
When accidents, wind storms, etc. disrupt electrical power supply to your
house, switch thermostat to “OFF” position. CAUTION: if the power was off
more than 8 hours DO NOT switch to
“COOLING” or “AUTO” until electrical
power has been re-established for 8
hours. NOTE: Your Stealth high efficiency air conditioning system has
many built-in features to protect the unit:
1. After a power interruption or thermostat off cycle the system will delay its
start-up for five minutes to prevent the
unit from short cycling.
2. Anytime the power “dips” or is lower
than normal; the Comfort Enhancer
Control™ will prevent the unit from
operating to prevent possible damage.
SYSTEM OPERATION
MANUAL CHANGE-OVER
THERMOSTAT
COOLING YOUR HOME - With the
comfort control switch in the “COOL”
position, the system will operate as follows: When the indoor temperature
rises above the level indicated by the
temperature adjustment setting, the
system will start. The outdoor unit will
operate and the indoor fan will circulate
the cooled, filtered air. When the room
temperature is lowered to the setting
selected, the system will shut off. HEATING YOUR HOME - If your system
includes a heating unit and the comfort
control switch is in the “HEAT” position,
the system will operate as follows:
When the indoor temperature drops
below the level indicated by the temperature adjustment setting, the system will
start. The heating system will operate
and the indoor fan will circulate the filtered air. When the room temperature
rises to the setting selected, the system
will shut off. Whether heating or cooling,
the fan will continue to operate if the fan
switch was set in the “ON or Intelligent”
position. The “AUTO” setting on the fan
switch will allow the fan to shut off when
your system does.
ELECTRONIC THERMOSTAT
The computerized electronic thermostat, when programmed, will function
automatically to operate the system as
follows: When the indoor temperature
rises above the higher (COOL) setting,
the outdoor unit will operate and the
indoor fan will circulate the cooled, filtered air. When the room temperature is
lowered to the selected level, the system will shut off. The indoor fan will
either shut off or run continuously,
depending upon your choice of fan
switch setting. When the indoor temperature is lowered to the selected level,
the system will shut off. The indoor fan
will either shut off or run continuously,
depending upon your choice of fan
switch setting. When the indoor temperature drops below the lower (HEAT) setting, the heating system will operate,
and the indoor fan will circulate the
heated, filtered air. When the indoor
temperature rises to the selected setting, the system will shut off.
1. Once the desired temperature is
selected on the thermostat, the unit will
delay its start up for five seconds to prevent unnecessary opertion of the unit as
a result of thermostat “jiggling”.
2. When the system switches from first
to second stage operation, there will be
an five second delay during transition.
CARE OF SYSTEM
YORK strongly recommends regular
periodic preventative maintenance on
this equipment. The person most
familiar with the equipment in your
H.V.A.C. system is a YORK dealer.
The YORK dealer can ensure your
maintenance program meets the conditions of the “YORK Warranty”, maximize the efficiency of the equipment,
and service your unit within the federally mandated guidelines with regard
to unlawful discharge of refrigerants
into the atmosphere.

COIL CARE
Keep the outdoor unit free of foliage,
grass clippings, leaves, paper, and any
other material which could restrict the
proper air flow in an out of the unit. The
coil may be vacuumed to remove any
debris from between the fins. If the coil
becomes excessively dirty, turn the
main disconnect switch to “Off” and
wash the coil with your garden hose.
Avoid getting water into the fan motor
and control box. Flush dirt from base
pan after cleaning the coil.
CARE OF FAN MOTORS
Some fan motors are provided with
lubrication ports. Inspect your indoor
and outdoor units to determine whether
or not lubrication ports are provided.
The fan motor is shipped with an oil supply which will last for several years
under normal operating conditions.
After this time, each motor bearing
should be oiled with 10 - 15 drops
(approximately 1/4 teaspoon) of SAE 20
non-detergent electric motor oil or automobile oil. DO NOT use definite purpose oils such as sewing machine,
cleaning, rust preventative, cutting,
household, etc.

2. Outdoor section for leaf or debris
blockage. Eliminate problem, turn off
the thermostat for 10 seconds and
attempt start. Wait 5 minutes. If system
does not start, call your YORK servicing
dealer.
FILTER CARE
Inspect the air filter(s) at least once a
month. If they are dirty, wash reusable
filters with a mild detergent per manufacturer’s recommendations. Replace
disposable filters with new filters. Install
the clean filters with “air flow” arrow in
the same direction as the air flow in your
duct. Filters should be clean to assure
maximum efficiency and ade-quate air
circulation.
CLEARANCES
The minimum clearances shown below
must be maintained should any patio or
yard improvements be done around the
outdoor unit.

your system heat or cool any faster.
Adjust your thermostat to a comfortable
setting and leave it there.
DON’T restrict air circulation. Placing
furniture, rugs, etc. in such a way that
they interfere with air vents will make
you system work harder to achieve a
comfortable temperature level. This
requires more energy, which means
greater cost to you.
DON’T heat or cool when you are away.
If you are going to be away for a day or
more, re-adjust your thermostat accordingly. Your furniture is far less demanding than you are when it comes to
comfort levels. However, don’t expect
the system to restore comfort conditions
immediately upon returning home. It will
take a little time.
DON’T locate lamps or other heat-producing appliances (radios, TV’s, heaters, etc.) near your thermostat. The
heat from these items will give your
thermostat “false information” about the
tem-perature in the room.
DO select a comfortable thermostat setting, but keep in mind that moderation in
temperature selection will save energy.
PARTS INFORMATION
SERVICE CALLS
There are a few instances where the
user can avoid unnecessary service
calls. If unit stops functioning properly
check the following items before calling
your YORK servicing dealer:
1. Indoor section for dirty filter.
Replacement parts are available from
local YORK contractor/dealer or the
nearest YORK distribution center.
COMFORT ASSURANCE
Special warranty packages (called
Comfort Assurance) are available thru
your contractor. These packages
reduce the potential cost of service calls
following the first year of operation on
your cooling (or heating/cooling) system.
SOME EFFICIENCY
DO’S & DON’TS
DON’T heat or cool unused household
area. Reduce supply and return air flow
to a minimum in areas which are not living spaces (storage rooms, garages,
basements, etc).
DON’T be a “thermostat jiggler”. Moving
your thermostat setting will not make
