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.

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.

NOTE: A roof curb can be used to utilize bottom discharge.
APG/GPG 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.

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 thermostatic
expansion valves (TXV) or 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/GPG three phase units use three phase compressors.
Starting components and run capacitors are therefore not
required.

A/GPG Package Gas 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 & 5 ton sizes. They
are designed for 208/230 volt single phase applications or
208/230 volt 3 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.

A/GPG model units use either PSC or X13 type indoor blower
motors. X-13 motors are constant torque motors with very low
power consumption and are energized by a 24V signal from
the ignition control board. The X-13 features 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.

Most A/GPG 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 oilbased 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.

Some models of the A/GPG15 series package units use a 2
stage scroll compressor. The basic scroll design has been
modified with the addition of an internal unloading mecha­nism that opens a by-pass port in the first compression
pocket, effectively reducing the displacement of the scroll.
The opening and closing of the by-pass port is controlled by
an internal electrically operated solenoid.

The ZPS modulated scroll uses a single step of unloading
to go from full capacity to approximately 67% capacity. A
single speed, high efficiency motor continues to run while
the scroll modulates between the two capacity steps.

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.

16

PRODUCT DESIGN

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.

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.

JUNCTION BOX

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.

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.

CHECKING THE GAS PIPING

CAUTION

TO A VOID THE POSSIBILITY OF PROPERTY DAMAGE,
PERSONAL INJUR Y 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
damage the gas valve and cause overfiring which may result
in heat exchanger failure.

This unit must be isolated from the gas supply system by
closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.48 kPa).

TANKS AND PIPING - PROPANE UNITS

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.
