To avoid possible injury, explosion or death, practice
safe handling of refrigerants.
SAFE REFRIGERANT HANDLING
Whilethese items will not covereveryconceivable situation, they should serveasauseful guide.
The successful development of hermetically sealed refrig-
erationcompressorshascompletelysealedthecompressor's
moving parts and electric motor inside a common housing,
minimizing refrigerant leaks and the hazards sometimes
associated with moving belts, pulleys or couplings.
Fundamental to the design of hermetic compressors is a
methodwherebyelectricalcurrentis transmitted to thecom-
pressor motor through terminal conductors which pass
throughthecompressor housing wall. These terminals are
sealedinadielectricmaterialwhichinsulatesthemfromthe
housingandmaintainsthepressure tight integrityoftheher-
metic compressor. The terminals and their dielectric em-
bedmentarestronglyconstructed,butarevulnerabletocare-
lesscompressorinstallation ormaintenanceproceduresand
equallyvulnerabletointernalelectricalshortcircuitscaused
by excessive system contaminants.
System contaminants, improper service procedure
and/or physical abuse affecting hermetic compressor
electrical terminals may cause dangerous system
venting.
In either of these instances, an electrical short between the
terminal and the compressor housing may result in the loss
of integrity between the terminal and its dielectric embed-
ment. This loss may cause the terminals to be expelled,
therebyventingthevaporousandliquidcontents of the com-
pressor housing and system.
Aventingcompressorterminalnormallypresentsnodanger
toanyone,providingtheterminalprotectivecover is properly
in place.
If, however, the terminal protective cover is not properly in
place,aventingterminalmay discharge a combinationof
(a) hot lubricating oil andrefrigerant
(b) flammable mixture (if system is contaminated
withair)
in a stream of spray which may be dangerous to anyone in
the vicinity. Death or serious bodily injury could occur.

SeeServiceSectionS-17forproperservicing.
To avoid possible explosion, use only returnable (not
disposable) service cylinders when removing refrigerant
from a system.-
• Ensure the cylinder is free of damage which could
lead to a leak or explosion.
• Ensure the hydrostatic test date does not exceed
5 years.
• Ensure the pressure rating meets or exceeds
400 lbs.
When in doubt, do not use cylinder.

Refrigerantflowcontrolisachievedbyuse of restrictor orifices
orthermostaticexpansionvalves (TXV).
The single phase units use permanent split capacitors (PSC)
design compressors. Starting components are therefore not
required. Alow MFD run capacitorassiststhe compressor to
start and remains in the circuit during operation.
The outdoor fan and indoor blower motors are single phase
capacitor type motors.
Air for condensing (cooling) is drawn through the outdoor coil
by a propeller fan, and is discharged vertically out the top of
the unit. The outdoor coil is designed for .0 static. No addi-
tionalrestriction(ductwork) shall be applied.
Conditioned air is drawn through the filter(s), field installed,
acrosstheevaporatorcoil and backintotheconditionedspace
bytheindoorblower.
Some APG/GPG series package units use a two-stage scroll
compressor. Thetwo-stepmodulator has an internal unload-
ing mechanism that opens a bypass port in the first compres-
sionpocket,effectivelyreducing thedisplacementofthescroll.
Theopeningandclosingofthebypassportiscontrolledbyan
internalelectricallyoperatedsolenoid.
TheZPS/ZRStwo-stepmodulatedscrollusesasinglestepof
unloading to go from full capacity to approximately 67% ca-
pacity. A single speed, high efficiency motor continues to run
while the scroll modulates between the two capacity steps.
Other A/GPG series package units use the Compliant Scroll
compressor,insteadoftraditionalreciprocatingcompressor.
A scroll is an involute spiral which, when matched with a mat-
ingscrollformasshown,generatesaseriesofcrescentshaped
gas pockets between the two members.
Duringcompression,one scrollremainsstationary(fixedscroll)
whiletheotherform (orbiting scroll) is allowed to orbit (but not
rotate)aroundthefirstform.
Asthismotionoccurs,the pockets between the two forms are
slowly pushed to the center of the two scrolls while simulta-
neously being reduced in volume. When the pocket reaches
the center of the scroll form, the gas, which is now at a high
pressure, is discharged out of a port located at the center.
During compression, several pockets are being compressed
simultaneously, resultingina very smooth process. Both the
suction process (outer portion of the scroll members) and the
dischargeprocess(innerportion)arecontinuous.
SomedesigncharacteristicsoftheCompliantScrollcompres-
sorare:
• Compliant Scroll compressors are more tolerant of liquid
refrigerant.
NOTE: Even though the compressor section of a Scroll
compressorismoretolerantof liquid refrigerant, continued
floodbackorfloodedstartconditions may washoilfromthe
bearingsurfacescausingprematurebearing failure.
• CompliantScrollcompressors use white oil which iscom-
patible with 3GS. 3GS oil may be used if additional oil is
required.
• Compliant scroll compressors perform "quiet" shutdowns
that allow the compressor to restart immediately without
theneedfora time delay.Thiscompressorwillrestart even
if the system has not equalized.

CHECKINGTHEGAS PIPING
To avoid the possibility of property damage, personal
injury or fire, the following instructions must be
performed regarding gas connections and pressure
testing.
The unit and its gas connections must be leak tested before
placing in operation. Because of the danger of explosion or
fire, never use a match or open flame to test for leaks. Never
exceed specified pressure for testing. Higher pressure may
damagethegasvalve andcauseoverfiringwhichmay resultin
heatexchangerfailure.
This unit must be isolated from the gas supply system by
closingitsindividualmanualshutoffvalveduring any pressure
testingofthegassupplypipingsystem at test pressures equal
to or less than 1/2 psig (3.48 kPa).

PERSONAL INJURY HAZARD
Iron Oxide (rust) can reduce the level of odorant in
propane gas. A gas detecting device is the only
reliable method to detect a propane gas leak. Contact
your local propane supplier about installing a gas
detecting warning device to alert you in the event
that a gas leak should develop. Failure to detect a
propane gas leak could result in an explosion or fire
which could cause serious personal injury or death.
All propane gas equipment must conform to the safety stan-
dards of the National Board of Fire Underwriters (See NBFU
Manual 58) or Natural Standards of Canada B149.2, Installa-
tionCodeforPropaneGas BurningAppliancesandEquipment.
For satisfactory operation, propane gas pressure must be 10
inchW.C.attheunitmanifoldwithallgasappliances in opera-
tion. Maintainingpropergaspressuredependsonthreemain
factors.
1. Vaporizationrate,whichdepends on(a)temperatureofthe
liquid, and (b) "wetted surface" area of the container or
containers.
2. Proper pressure regulation. (Two-stageregulationisrec-
ommendedfromthestandpointofbothcostandefficiency.)
3. Pressure drop in lines between regulators, and between
second stage regulator and the appliance. Pipe size re-

If your propane gas appliance is installed in an
excavated area or a confined space, we strongly
recommend that you contact your propane supplier
about installing a gas detecting warning device that
would alert you to a gas leak.
• Propane gas is heavier than air and any leaking gas
can settle in any low areas or confined spaces.
• Propane gas odorant may fade, making the gas
undetectable except with a warning device.
An undetected gas leak will create a danger of
explosion or fire. If you suspect the presence of gas,
follow the instructions on page 6. Failure to do so
could result in serious personal injury or death.

SYSTEM OPERATION HEATING CYCLE
When the contacts of the room thermostat close, the termi-
nals R to W on the control board are energized.
The heating cycle is accomplished by using a unique tubular
designheatexchangerwhich provides efficientgasheatingon
eithernaturalgasorpropanegasfuels. Theheatexchangers
compacttubularconstructionprovidesexcellent heat transfer
formaximumoperatingefficiency.
Inshot type gas burners with integral cross lighters are used
eliminating the need for adjustable air shutters. The same
burner is designed for use on either natural or propane gas
fuels.
The induced draft blower draws fuel and combustion air into
theburnersandheatexchangerforpropercombustion. A pres-
sure switch is used in conjunction with the I. D. blower to de-
tect a blocked flue condition.
Blower operation is controlled by the ignition control module.
The module allows for field adjustment of the blower delay at
the end of the heating cycle. The range of adjustment is for
120,135,or150 seconds. The factory delay setting is 30 sec-
onds delay on 150 seconds delay off.

APG/GPGunits are equipped withadirect spark ignition sys-
tem. Ignition is provided by 22,000 volt electronic spark. A

ing thermostats with an adjustable heat anticipator.
NOTE: Some night setback thermostats that do not have a
common terminal, use a power robbing circuit in the off cycle
tomaintainthebatteries. This type ofthermostatmayinterfere
withtheoperationof the ignitioncontrolmoduleandshould not
beused.
HEATINGSEQUENCE
In order to illustrate the heating sequence, the following has
beensimplifiedtogive a better understanding of the pressure
switchoperation.
Thefigurebelowisaviewoftheinduceddraftblowershowing
the location of the pressure tap. The induced draft blower is
mounted on the collector box, where the combustion gases
fromtheheatexchanger are drawn through the collector box.

The refrigerant used in the system is R-22. It is clear, color-
less, non-toxic, non-irritating, and non-explosive liquid. The
chemicalformulaisCHCIF2. Theboiling point, at atmospheric
pressureis-41.4°F.
A few of the important principles that make the refrigeration
