1 Rated in accordance with AHRI standard 270 (2015). AHRI Standard 270 establishes a method of rating outdoor unitary equipment in terms of
Sound Power.
2 Rated in accordance with AHRI standard 275 (2010). AHRI Standard 275 provides the calculations for estimating the A-Weighted Sound Pressure
at a given distance from the equipment. That is a more useful number because that is what humans will hear.
3 Based only on distance factor; other factors may change this value such as:
- Unit location (reective surfaces adjacent to the unit)
- Barrier shielding sources
- Sound path/elevation
- Outside noise sources

• Locate unit away from overhanging roof lines which
would allow water or ice to drop on, or in front of, coil
or into unit.
When outdoor unit is connected to factory-approved indoor
unit, outdoor unit contains system refrigerant charge for
operation with matching indoor unit when connected by 15
ft. of eld-supplied tubing. For proper unit operation, check
refrigerant charge using charging information located on
control box cover.
Outdoor Section
Zoning ordinances may govern the minimum distance the
condensing unit can be installed from the property line.
Install on a Solid, Level Mounting Pad
The outdoor section is to be installed on a solid foundation.
This foundation should extend a minimum of 2” (inches)
beyond the sides of the outdoor section. To reduce the
possibility of noise transmission, the foundation slab
should NOT be in contact with or be an integral part of the
building foundation. See Figure 2.
If conditions or local codes require the unit be attached to
pad or mounting frame, tie down bolts should be used and
secured to unit base pan.

Table 1.
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
who have jurisdiction before installation.
Installation
NOTE: In some cases, noise in the living area has been
traced to gas pulsations from improper installation of
equipment.
• Locate unit away from windows, patios, decks, etc.
where unit operation sounds may disturb customer.
• Leave some slack between structure and unit to
absorb vibration.
• Place a sound-absorbing material, such as Isomode,
under the unit if it will be installed in a location or
position that will transmit sound or vibration to the
living area or adjacent buildings.
• In heavy snow areas, do not locate the unit where
drifting snow will occur. The unit base should be
elevated above the depth of average snows.
NOTE: Elevation of the unit may be accomplished
by constructing a frame using suitable materials. If a
support frame is constructed, it must not block drain
holes in unit base.
• When installed in areas where low ambient
temperatures exist, locate unit so winter prevailing
winds do not blow directly into outdoor coil.

Elevate Unit
Accumulation of water and ice in base pan may cause
equipment damage.
CAUTION
Elevate unit per local climate and code requirements to
provide clearance above estimated snowfall level and
ensure adequate drainage of unit. Use snow stand in areas
where prolonged freezing temperatures are encountered.
If conditions or local codes require the unit be attached to
pad or mounting frame, tie down bolts should be used and
fastened through knockouts provided in unit base pan.
Clearance Requirements
When installing, allow su󰀩cient space for airow clearance,
wiring, refrigerant piping, and service. For proper airow,
quiet operation and maximum e󰀩ciency. Position so water,
snow, or ice from roof or eaves cannot fall directly on unit.
Refer to Table 2 for installation clearances.

DO LOCATE THE UNIT:
• With proper clearances on sides and top of unit
• On a solid, level foundation or pad (unit must be level
to within ± 1/4 in./ft. per compressor manufacturer
specications)
• To minimize refrigerant line lengths
DO NOT LOCATE THE UNIT:
• On brick, concrete blocks or unstable surfaces
• Near clothes dryer exhaust vents where debris
accumulates
• Near sleeping area or near windows
• Under eaves where water, snow or ice can fall directly
on the unit
• With clearance less than 2 ft. from a second unit
• With clearance less than 4 ft. on top of unit
Rooftop Installations
Install unit at a minimum of 6” above surface of the roof
to avoid ice buildup around the unit. Locate the unit
above a load bearing wall or area of the roof that can
adequately support the unit. Consult local codes for rooftop
applications.
If unit cannot be mounted away from prevailing winds, a
wind barrier should be constructed. Due to variation in
installation applications, size and locate barrier according
to the best judgment of the installer.

508216-01 Issue 2130 Page 17 of 42
Torque Requirements
When servicing or repairing heating, ventilating, and
air conditioning components, ensure the fasteners are
appropriately tightened. Table 3 lists torque values for
fasteners.
To prevent stripping of the various caps used, the
appropriately sized wrench should be used and tted
snugly over the cap before tightening.
IMPORTANT
When servicing or repairing HVAC components, ensure
the fasteners are appropriately tightened. Table 3 provides
torque values for fasteners.
Only use Allen wrenches of su󰀩cient hardness (50Rc
- Rockwell Harness Scale minimum). Fully insert the
wrench into the valve stem recess.
Service valve stems are factory-torqued (from 9 ft-lbs
for small valves, to 25 ft-lbs for large valves) to prevent
refrigerant loss during shipping and handling. Using an
Allen wrench rated at less than 50Rc risks rounding
or breaking o󰀨 the wrench, or stripping the valve stem
recess.
IMPORTANT
Parts Recommended Torque
Service valve cap 8 ft.-lb. 11 NM
Sheet metal screws 16 in.-lb. 2 NM
Machine screws #10 28 in.-lb. 3 NM
Compressor bolts 90 in.-lb. 10 NM
Gauge port seal cap 8 ft.-lb. 11 NM
Table 3. Torque Requirements
Using Manifold Gauge Set
When checking the system charge, only use a manifold
gauge set that features low loss anti-blow back ttings.
Manifold gauge set used with HFC-410A refrigerant
systems must be capable of handling the higher system
operating pressures.
The gauges should be rated for use with pressures of 0 -
800 psig on the high side and a low side of 30” vacuum to
250 psig with dampened speed to 500 psi. Gauge hoses
must be rated for use at up to 800 psig of pressure with a
4000 psig burst rating.
Operating Service Valves
The liquid and vapor line service valves are used for
removing refrigerant, ushing, leak testing, evacuating,
checking charge and charging. Each valve is equipped
with a service port which has a factory-installed valve stem.
Liquid and Suction Line Service Valves
The liquid line and suction line service valves (see Figure
4) and service ports are used for leak testing, evacuation,
charging, and checking charge.
Each valve is equipped with a service port which has a
factory-installed Schrader valve. A service port cap protects
the Schrader valve from contamination and serves as the
primary leak seal.
To Access the Schrader Port:
1. Remove the service port cap with an adjustable
wrench.
2. Connect gauge to the service port.
3. When testing is completed, replace service port cap.
Tighten nger tight, then an additional 1/6 turn.
To Open Liquid or Suction Line Service Valve:
1. Remove stem cap with an adjustable wrench.
2. Use service wrench with a hex-head extension to back
the stem out counterclockwise as far as it will go. Use a
3/16” hex head extension for liquid line service valves
and a 5/16” extension for suction line service valves.
3. Replace the stem cap. Tighten nger tight, then tighten
an additional 1/6 turn.
To Close Liquid or Suction Line Service Valve:
1. Remove the stem cap with an adjustable wrench.
2. Use a service wrench with a hex-head extension to
turn the stem clockwise to seat the valve. Tighten
rmly.
3. Replace the stem cap. Tighten nger tight, then tighten
an additional 1/6 turn.
Suction Line (Ball Type) Service Valve
Suction line (ball type) service valves function the same
way as the other valves; the di󰀨erence is in the construction
(see Figure 5).
The ball valve is equipped with a service port with a factory-
installed Schrader valve. A service port cap protects the
Schrader valve from contamination and serves as the
primary seal.

508216-01Issue 2130Page 18 of 42
Refrigeration Piping
• Use only refrigerant grade copper tubes.
• Split systems may be installed with up to 50 feet of
line set (no more than 20 feet vertical) without special
consideration (see long line set guidelines).
• Ensure that vapor and liquid tube diameters are
appropriate to capacity of unit.
• Run refrigerant tubes as directly as possible by
avoiding unnecessary turns and bends.
• When passing refrigerant tubes through the wall, seal
opening with RTV or other silicon-based caulk.
• Avoid direct tubing contact with water pipes, duct work,
oor joists, wall studs, oors, walls, and any structure.
• Do not suspend refrigerant tubing from joists and
studs with a rigid wire or strap that comes in direct
contact with tubing.
• Ensure that tubing insulation is pliable and completely
surrounds vapor tube.
It is important that no tubing be cut or seals broken until you
are ready to actually make connections to the evaporator
and to the condenser section. DO NOT remove rubber
plugs or copper caps from the tube ends until ready to
make connections at evaporator and condenser. Under no
circumstances leave the lines open to the atmosphere for
any period of time, if so unit requires additional evacuation
to remove moisture.

Be extra careful with sharp bends. Tubing can “kink” very
easily, and if this occurs, the entire tube length will have
to be replaced. Extra care at this time will eliminate future
service problems.

It is recommended that vertical suction risers not be up-
sized. Proper oil return to the compressor should be
maintained with suction gas velocity.
Filter Drier
The lter drier is very important for proper system operation
and reliability. If the drier is shipped loose, it must be
installed by the installer in the eld. Unit warranty will be
void, if the drier is not installed.
Installation of Line Sets
DO NOT fasten liquid or suction lines in direct contact with
the oor or ceiling joist. Use an insulated or suspension
type of hanger. Keep both lines separate, and always
insulate the suction line. Liquid line runs (30 feet or more)
in an attic will require insulation. Route refrigeration line
sets to minimize length.
DO NOT let refrigerant lines come in direct contact with
foundation. When running refrigerant lines through the
foundation or wall, openings should allow for a sound
and vibration absorbing material to be placed or installed
between tubing and foundation. Any gap between
foundation or wall and refrigerant lines should be lled with
a vibration damping material.
If ANY refrigerant tubing is required to be buried by state
or local codes, provide a 6 inch vertical rise at service
valve.
CAUTION
Installation into an Existing R-22 System
If the unit will be installed in an existing system that uses
an indoor unit or line sets charged with R-22 refrigerant,
installer must perform the following procedures to convert
the system to an R-410A system.
Remove Existing Expansion Valve
1. On fully cased coils, remove the coil access and
plumbing panels.
2. Remove any shipping clamps from the liquid line and
distributor assembly.
3. Disconnect the equalizer line from the check expansion
valve equalizer line tting on the vapor line.
4. Remove the vapor line sensing bulb.
5. Disconnect the liquid line from the check expansion
valve at the liquid line assembly.
6. Disconnect the check expansion valve from the liquid
line orice housing. Take care not to twist or damage
distributor tubes during this process.
7. Remove and discard check expansion valve and the
two Teon® rings (see Figure 6).
8. Use a eld-provided tting to temporarily reconnect the
liquid line to the indoor unit’s liquid line orice housing.

Flushing Line Sets
If the unit will be installed in an existing system that uses
an indoor unit or line sets charged with R-22 refrigerant,
installer must perform the following ushing procedure.
NOTE: Existing system components (including line set
and indoor coil) must be an AHRI match with the unit in
order to fulll unit warranty requirements.
Refrigerant must be reclaimed in accordance with
national and local codes.
WARNING
Do NOT attempt to ush and re-use existing line sets
or indoor coil when the system contains contaminants
(i.e., compressor burn out).
CAUTION
“Clean refrigerant” is any refrigerant in a system that
has not had compressor burnout. If the system has
experienced burnout, it is recommended that the
existing line set and indoor coil be replaced.
NOTE
In lieu of R-410A, an industry-standard ushing agent
may also be used.
