WARNING
IMPORTANT INFORMATION
SAFE REFRIGERANT HANDLING
While these items will not cover every conceivable situation, they should serve as a useful guide.
WARNING
Refrigerants are heavier than air. They can "push out" the oxygen in your lungs or in any enclosed space.To
avoid possible difficulty in breathing or death:
Never purge refrigerant into an enclosed room or
space. By law, all refrigerants must be reclaimed.
If an indoor leak is suspected, thoroughly ventilate
the area before beginning work.
• Liquid refrigerant can be very cold. To avoid possible frostbite or blindness, avoid contact with refrigerant and wear gloves and goggles. If liquid refrigerant does contact your skin or eyes, seek medical help immediately.
• Always follow EPA regulations. Never burn refrig­ erant, as poisonous gas will be produced.
WARNING
To avoid possible injury, explosion or death, practice safe handling of re frige rants.
WARNING
The compressor POE oil for R-410A units is extremely susceptible to moisture absorption and could cause compressor failure. Do not leave system open to atmosphere any longer than necessary for installation.
WARNING
To avoid pos sible exp los ion:
Never apply flame or steam to a refrigerant cylinder. If you must heat a cylinder for faster charging, partially immers e it in wa rm w ate r.
Never fill a cylin de r m ore than 80% fu ll of liqu id refrigerant.
• Never add anything other than R-22 to an R-22 cylinder or R-410A to an R-410A cylinder. The service equipment used must be listed or certified for the type of refrigerant used.
• Store cylinders in a cool, dry place. Never use a cylinder as a plat form or a roller.
WARNING
To avoid possible explos ion, use only returnable (not disposable) service cylinders when removing refrig­erant f rom a syst em.
• 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.
WARNING
System contamina nts, improper se rvice procedure and/or physical abuse affecting hermetic com pressor electrical terminals may cause dangerous s ystem venting.
The successful development of hermetically sealed refrig­eration compressors has completely sealed the compressor'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 method whereby electrical current is transmitted to the compressor motor through terminal conductors which pass through the compressor housing wall. These terminals are sealed in a dielectric material which insulates them from the housing and maintains the pressure tight integrity of the hermetic compressor. The terminals and their dielectric embedment are strongly constructed, but are vulnerable to careless compressor installation or maintenance proce­dures and equally vulnerable to internal electrical short circuits caused by excessive system contaminants.
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 embed­ment. This loss may cause the terminals to be expelled, thereby venting the vaporous and liquid contents of the compressor housing and system.
A venting compressor terminal normally presents no danger to anyone, providing the terminal protective cover is properly in place.
If, however, the terminal protective cover is not properly in place, a venting terminal may discharge a combination of
(a) hot lubricating oil and refrigerant (b) flammable mixture (if system is contaminated
with air)
in a stream of spray which may be dangerous to anyone in the vicinity. Death or serious bodily injury could occur.
Under no circumstances is a hermetic compressor to be electrically energized and/or operated without having the terminal protective cover properly in place.
See Service Section S-17 for proper servicing.

PRODUCT DESIGN
Locations and Clearances
NOTE: To ensure proper condensate drainage, unit must be
installed in a level position.
In installations where the unit is installed above ground level and not serviceable from the ground (Example: Roof Top installations) the installer must provide a service platform for the service person with rails or guards in accordance with local codes or ordinances or in their absence with the latest edition of the National Fuel Gas Code ANSI Z223.1.
IMPORTANT NOTE: If using bottom discharge with roof curb, ductwork should be attached to the curb prior to installing the unit.
Refer to Roof curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.
NOTE: Roof overhang should be no more than 36".
Minimum clearances are required to avoid air recirculation and keep the unit operating at peak efficiency. A minimum 12 inch clearance is required to the condenser coil.
NOTE: The flue outlet hood is packaged separately inside the unit and must be installed prior to operation.
WARNING
TO PREVENT POSSIBLE DAMAGE, THE UNIT SHOULD REMAIN I N AN UPRIGH T POSI TION DURI NG ALL RIGGING AND MOVI NG OPERATI ONS. TO FACIL ITATE LIFTING AND MOVI NG IF A CR ANE IS USED , PLAC E THE UN IT IN AN AD EQUATE CAB LE SL I DE .
NOTE: A roof curb can be used to utilize bottom discharge.
*PD14 Package Units are designed for outdoor installations
only in either residential or light commercial applications.
NOTE: To ensure proper condensate drainage, unit must be
installed in a level position.
The connecting ductwork (Supply and Return) can be con­nected for either horizontal or down discharge airflow. In the down discharge applications a matching Roof Curb is recom­mended .
A return air filter must be installed behind the return air grille(s) or provision must be made for a filter in an accessible location within the return air duct. The minimum filter area should not be less than those sizes listed in the Specification Section. Under no circumstances should the unit be oper­ated without return air filters.
13
PRODUCT DESIGN
A 3/4" - 14 NPT drain connector is provided for removal of condensate water from the indoor coil. In order to provide proper condensate flow, do not reduce the drain line size. NOTE: Tighten drain to a maximum torque of 10 in-lbs.
Refrigerant flow control is achieved by use of a flowrator. The single phase models use permanent split capacitors
(PSC) design compressors. Starting components are there­fore not required. A low MFD run capacitor assists the compressor to start and remains in the circuit during opera­tion.
A/GPD Package Units are designed for outdoor installations only in either residential or light commercial applications and are available in 2, 2.5, 3, 3.5 & 4 ton sizes. They are designed for 208/230 volt single phase applications.
The connecting ductwork (Supply and Return) can be con­nected for either horizontal or vertical airflow. In the vertical application, a matching Roof Curb is recommended.
A return air filter must be installed behind the return air grille(s) or provision must be made for a filter in an accessible location within the return air duct (3 phase models have an internal downflow filter rack). The minimum filter area should not be less than those sizes listed in the Specification Section. Under no circumstances should the unit be oper­ated without return air filters.
*PD model units use EEM type indoor blower motors. EEM motors are constant torque motors with very low power consumption and are energized by a 24V signal from the ignition control board. The EEM motors feature an inte­grated control module.
Air for condensing (cooling cycle) 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 additional restriction (ductwork) shall be applied.
Conditioned air is drawn through the filter(s), field installed, across the coil and back into the conditioned space by the indoor blower.
*PD series package units use the Compliant Scroll compres­sor; there are a number of design characteristics which are different from the traditional reciprocating compressor.
- Due to their design Scroll compressors are inherently more tolerant of liquid refrigerant. NOTE: Even though the compressor section of a Scroll compressor is more tolerant of liquid refrigerant, continued flood back or flooded start conditions may wash oil from the bearing surfaces causing premature bearing failure.
- These Scroll compressors use "POE" or polyolester oil which is NOT compatible with mineral oil based lubri­cants like 3GS. "POE" oil must be used if additional oil is required.
- Compliant scroll compressors perform “quiet” shut­downs that allow the compressor to restart immediately without the need for a time delay. This compressor will restart even if the system has not equalized.
- Operating pressures and amp draws may differ from standard reciprocating compressors. This information may be found in the “Cooling Performance Data” sec­tion.
A scroll is an involute spiral which, when matched with a mating scroll form as shown, generates a series of crescent shaped gas pockets between the two members.
During compression, one scroll remains stationary (fixed scroll) while the other form (orbiting scroll) is allowed to orbit (but not rotate) around the first form.
As this motion occurs, the pockets between the two forms are slowly pushed to the center of the two scrolls while simultaneously 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, resulting in a very smooth process. Both the suction process (outer portion of the scroll members) and the discharge process (inner portion) are continuous.
ELECTRICAL WIRING
The units are designed for operation on 60 hertz current and at voltages as shown on the rating plate. All internal wiring is complete. Ensure the power supply to the compressor contactor is brought to the unit as shown on the supplied unit wiring diagram. The 24V wiring must be connected between the unit control panel and the room thermostat.
LINE VOLTAGE WIRING
Power supply to the unit must be N.E.C. Class 1, and must comply with all applicable codes. The unit must be electrically grounded in accordance with the local codes or, in their absence, with the latest edition of the National Electrical Code, ANSI/NFPA No. 70, or in Canada, Cana­dian Electrical Code, C22.1, Part 1. A fused disconnected must be provided and sized in accordance with the unit minimum circuit ampacity.
The best protection for the wiring is the smallest fuse or breaker which will hold the equipment on line during normal operation without nuisance trips. Such a device will provide maximum circuit protection.

PRODUCT DESIGN
WARNING
DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON THE UNIT DATA PLATE.
The unit transformer is connected for 230V operation. If the unit is to operate on 208V, reconnect the transformer primary lead and the induced draft blower leads as shown on the unit wiring diagram.
All line voltage connections must be made through weather proof fittings. All exterior power supply and ground wiring must be in approved weather proof conduit. Low voltage wiring from the unit control panel to the thermostat requires coded cable. See the following figures for ground level and rooftop wiring.

WARNING
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 standards of the National Board of Fire Underwriters (See NBFU Manual 58) or Natural Standards of Canada B149.2, Installation Code for Propane Gas Burning Appliances and Equipment.
For satisfactory operation, propane gas pressure must be 10 inch W.C. at the unit manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors.
1. Vaporization rate, which depends on (a) temperature of the liquid, and (b) "wetted surface" area of the container or containers.
2. Proper pressure regulation. (Two-stage regulation is recommended from the standpoint of both cost and efficiency.)
3. Pressure drop in lines between regulators, and between second stage regulator and the appliance. Pipe size required will depend on length of pipe run and total load of all appliances.
Complete information regarding tank sizing for vaporization, recommended regulator settings, and pipe sizing is available from most regulator manufacturers and propane gas suppli­ers.
Propane is an excellent solvent, and special pipe dope must be used when assembling piping for this gas as it will quickly dissolve white lead or most standard commercial com­pounds. Shellac base compounds resistant to the actions of liquefied petroleum gases such as Gasolac®, Stalactic®, Clyde's or John Crane are satisfactory.

COOLING
The refrigerant used in the system is R-410A. It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125. The boiling point at atmo­spheric pressure is -62.9°F.
A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warmer to a cooler body. Under lower pressure, a refrigerant will absorb heat and vaporize at a low temperature. The vapors may be drawn off and condensed at a higher pressure and tempera­ture to be used again.

SCHEDULE 40
SCHEDULE 40
The indoor evaporator coil functions to cool and dehumidify the air conditioned spaces through the evaporative process taking place within the coil tubes.
NOTE: Actual temperatures and pressures are to be obtained from the expanded ratings in the Technical Information Manual.
High temperature, high pressure vapor leaves the compres­sor through the discharge line and enters the condenser coil. Air drawn through the condenser coil by the condenser fan causes the refrigerant to condense into a liquid by removing heat from the refrigerant. As the refrigerant is cooled below its condensing temperature it becomes subcooled.
The subcooled high pressure liquid refrigerant now leaves the condenser coil via the liquid line until it reaches the indoor expansion device.
As the refrigerant passes through the expansion device and into the evaporator coil a pressure drop is experienced causing the refrigerant to become a low pressure liquid. Low pressure saturated refrigerant enters the evaporator coil where heat is absorbed from the warm air drawn across the coil by the evaporator blower. As the refrigerant passes through the last tubes of the evaporator coil it becomes superheated, that is, it absorbs more heat than is necessary for the refrigerant to vaporize. Maintaining proper superheat assures that liquid refrigerant is not returning to the compres­sor which can lead to early compressor failure.
Low pressure superheated vapor leaves the evaporator coil and returns through the suction line to the compressor where the cycle begins again.
Heat Pump Models
Any time the room thermostat is switched to cool, the O terminal is energized. This energizes the 24 volt coil on the reversing valve and switches it to the cooling position.
When the contacts of the room thermostat close, this closes the circuit from R to Y and R to G in the unit.
This energizes the compressor contactor and will energize the EEM indoor blower motor after a 6-second delay.
When the thermostat is satisfied, it opens its contacts breaking the low voltage circuit causing the compressor contactor to open and indoor fan to stop after the programmed 60 second off delay on the EEM motor.
If the room thermostat fan selector switch should be set to the "on" position then the indoor blower would run continuous rather than cycling with the compressor.

PRODUCT DESIGN
HEATING/ GAS & L.P.
The heating cycle is accomplished by using a unique tubular design heat exchanger which provides efficient gas heating on either natural gas or propane gas fuels. The heat exchangers compact tubular construction provides excellent heat transfer for maximum operating efficiency.
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 the burners and heat exchanger for proper combustion. A pressure switch is used in conjunction with the I. D. blower to detect 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 90, 120, 150 or 180 seconds. The factory delay setting is 30 seconds delay on 150 seconds delay off.
Direct Spark Ignition (DSI) Systems
APD/GPD units are equipped with a direct spark ignition system. Ignition is provided by 22,000 volt electronic spark. A flame sensor then monitors for the presence of flame and closes the gas valve if flame is lost.
HEATING CYCLE
On a call for first stage heat, the contacts of the room thermostat close. This energizes terminals R to Y and R to G, the low voltage circuit to the contactor is completed starting the compressor and outdoor fan motor. This also energizes the EEM motor after approximately 6-seconds.
When the thermostat is satisfied, breaking the circuit be­tween R to Y and R to G, the compressor and outdoor fan motor will stop. The indoor blower will stop after a pro­grammed 60 second off delay.
NOTE: Should the second stage heating contacts in the room thermostat close, a W1 signal will be sent to the ignition control and the Y signal would be removed. A normal gas heating sequence would then follow.
