This unit can be located at ground floor level or on flat roofs. At
ground floor level, the unit must be on a solid, level foundation
that will not shift or settle. To reduce the possibility of sound
transmission, the foundation slab should not be in contact with
or be an integral part of the building foundation. The foundation
slab should be a minimum of 6” wider than the unit in all direc-
tions. Ensure the foundation is sufficient to support the unit. A
concrete slab raised above ground level provides a suitable base.
Theselectedsiteshouldbenogreaterthan50’belowor70’above
theevaporator section.For optimumperformance, the minimum
length interconnecting tubing is preferred. When possible mini-
mizethe amountof bendsandturns.
Rooftop Installations
If it is necessary to install this unit on a roof structure, ensure the
roof structure can support the weight and that proper consider-
ation is given to the weather-tight integrity of the roof. Since the
unit can vibrate during operation, sound vibration transmission
should be considered when installing the unit. Vibration absorb-
ing pads or springs can be installed between the condensing unit
legs or frame and the roof mounting assembly to reduce noise
vibration.
Rigging
To avoid possible injury or death, all panels must be in position
and secured before lifting this equipment.
Usefield-supplied spreader barswhen lifting theunit tominimize
the possibility of lifting cable/straps damage. To protect the cabi-
net louvers, use protective material such as plywood behind the
cable/straps. Arrange the straps to form a central suspension
point. NOTE: When raising and setting the unit, observe all safety
rules. Remove shipping skid and all protection and lifting mate-
rial after the unit is in place.
Safe Refrigerant Handling
Whiletheseitemswillnotcover every conceivable situation, they
should serve as a useful guide.

To avoid possible explosion:
Never apply flame or steam to a refrigerant cylinder. If you
must heat a cylinder for faster charging, partially immerse
it in warm water.
Never fill a cylinder morethan 80% fullof liquid refrigerant.
• Never add anything other than R-410A to an R-410A cylinder.
The service equipment used mustbe listed or certified for the
type of refrigerant used.
• Storecylinders in acool, dry place. Never use a cylinder
as a platform or a roller.
•
•
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 notuse cylinder.
Refrigerant Lines
NOTE:Forimprovedrefrigerantmanagement,equiptheevaporator
coil with a field-supplied thermal expansion valve (TXV) and the
liquid line with a field-supplied liquid line solenoid. Ensure the
solenoid is installed as close as possible to the evaporator coil to
prevent refrigeration migration in the compressor “OFF” cycle.
Useonlyrefrigerantgrade(dehydratedandsealed)coppertubing
toconnectthecondensingunit with the indoorevaporator. After
cutting the tubing, install plugs to keep refrigerant tubing clean
and dry prior to and during installation. Tubing should always be
cut square keeping ends round and free from burrs. Clean the
tubing to prevent contamination.
DoNOTletrefrigerantlinescomeindirectcontactwithplumbing,
ductwork, floor joists, wall studs, floors, and walls. When run-
ning refrigerant lines through a foundation or wall, openings
should allow for sound and vibration absorbing material to be
placed or installed between tubing and foundation. Any gap be-
tween foundation or wall and refrigerant lines should be filled
with a pliable silicon-based caulk, RTV or a vibration damping
material.Avoidsuspendingrefrigeranttubingfromjoistsandstuds
with rigid wire or straps that would come in contact with the
tubing. Use an insulated or suspension type hanger. Keep both
lines separate and always insulate the suction line.

Insulation is necessary to prevent condensation from forming
and dropping from the suction line. Armflex (or satisfactory
equivalent) with 3/8” min. wall thickness is recommended. In
severe conditions (hot, high humidity areas) 1/2” insulation may
be required. Insulation must be installed in a manner which
protects tubing from damage and contamination.
Where possible, drain as much residual compressor oil from ex-
isting systems, lines, and traps; pay close attention to low areas
whereoilmaycollect. NOTE:Ifchangingrefrigeranttypes,ensure
theindoorcoilandmeteringdeviceiscompatiblewiththetypeof
refrigerantbeingused;otherwise,theindoorcoilmustbereplaced.
To facilitate oil return to the compressor, a horizontal suction
line should be pitched (1/2” per 10’ toward the condensing unit.
FilterDrierandSightGlass
A liquid line filter drier is factory installed. Field-install the sup-
plied sight glass/moisture indicator on the liquid line as close as
practical to the service valve.
Burying Refrigerant Lines
If burying refrigerant lines can not be avoided, use the following
checklist.
1. Insulate liquid and suction lines separately.
2. Enclose all underground portions of the refrigerant lines in
waterproofmaterial(conduitorpipe)sealingtheendswhere
tubing enters/exits the enclosure.
3. If the lines must pass under or through a concrete slab,
ensure lines are adequately protected and sealed.
Refrigerant Line Connections
IMPORTANT:Toavoidoverheatingtheservicevalve,TXVvalve,
orfilterdrierwhile brazing, wrapthecomponent with awet
rag,or use athermalheat trapcompound asrecommended
by the compound manufacturer. Use a brazing alloy of 2%
minimum silver content. Do not use flux.

1. The ends of the refrigerant lines must be cut square, de-
burred,cleaned, andbe roundand free fromnicks or dents.
Any other condition increases the chance of a refrigerant
leak.
2. This unit is factory shipped with a holding charge. “Sweep”
therefrigerant linewith nitrogenor inert gasduring brazing
topreventtheformationofcopper-oxideinsidetherefriger-
ant lines.
3. Afterbrazing, quenchthe joints withwater ora wetcloth to
preventoverheating of theservicevalve.
4. Ensure the filter drier paint finish is intact after brazing. If
thepaintofthesteelfilterdrierhasbeenburnedorchipped,
repaint or treat with a rust preventative. This is especially
important on suction line filter driers which are continually
wetwhenthe unit is operating.
NOTE: Be careful not to kink or dent refrigerant lines. Kinked or
dentedlines willcausepoorperformanceorcompressor damage.
Do NOT make final refrigerant line connection until plugs are
removedfromrefrigeranttubing.
NOTE: Before brazing, verify indoor piston size by checking the
piston kit chart packaged with indoor unit.
Leak Testing (Nitrogen or Nitrogen-Traced)
To avoid the risk of fire or explosion, never use oxygen, high
pressure air or flammable gases for leak testing of a refrigeration
system.
Pressure test the system using dry nitrogen and soapy water to
locateleaks. Ifyouwishtousealeakdetector,chargethesystem
to 10 psi using the appropriate refrigerant then use nitrogen to
finish charging the system to working pressure then apply the
detector to suspect areas. If leaks are found, repair them. After
repair, repeat the pressure test. If no leaks exist, proceed to sys-
temevacuation.
System Evacuation
Condensing unit liquid and suction valves are closed to contain
the charge within the unit. The unit is shipped with the valve
stems closed and caps installed. Do not open valves until the
systemisevacuated.
1. Connectthevacuumpumpwith250microncapabilitytothe
service valves.
2. Evacuate the system to 250 microns or less using suction
and liquid service valves. Using both valves is necessary as
some compressors create a mechanical seal separating the
sides of the system.
3. Close pump valve and hold vacuum for 10 minutes. Typi-
cally pressure will rise during this period.

Three Phase Compressor Rotation
Use care when handling scroll compressors. Dome temperatures
could be hot.
CAUTION
Three phase scrolls are power phase dependent and can com-
press in more than one direction.
Verify proper rotation for three phase compressors by ensuring
the suction pressure drops and discharge pressure rises when
thecompressorisenergized. NOTE: When operated inreverse,a
three phase scroll compressors is noisier and its current draw
substantially reduced compared to marked values.

System Start Up
Never operate the compressor with the suction valve closed to
testthe compressor’spumping efficiency.In somecases, thiscan
result in serious compressor damage and loss of warranty cover-
age.
Forthe7-1/2tonunitstartingchargeshouldbe15lbs.ofR-410Aand
18 lbs. for the 10 ton unit. The length of line set, indoor unit
airflow, condensing unit location and number of tubing fittings
will have an impact on final unit charge amount. Turn the electri-
cal power on, and let the system run. Wait for the refrigerant
pressures to stabilize.
Charge Verification
CAUTION
NOTICE
Violation of EPA regulations may result in fines or other penalties.
Operating the compressor withthe suctionvalve closed willvoid
the warranty and cause serious compressor damage.
CAUTION
Final Charge Adjustment
The outdoor temperature must be 60°F or higher. Set the room
thermostattoCOOL,fanswitchtoAUTO,andsetthetemperature
controlwellbelowroomtemperature.
After system has stabilized per startup instructions, check sub-
cooling and superheat as detailed in the following section.
Expansion Valve System
NOTE:EXPANSIONVALVEBULBMUSTBEINPLACEONSUCTIONLINE
&INSULATED.
Expansion Valve Indoors
Atstabilized cooling conditionsand withan outdoor temperature
of 60°F or higher, the system should have from 9°F to 13°F
subcooling. For a proper subcooling reading, measure the refrig-
erant pressure and temperature at the outdoor unit’s liquid line
service valve. If you have less than 9°F subcooling, slowly adjust
the charge by adding refrigerant. If you have more than 13°F
subcooling, slowly adjust the charge by removing refrigerant.
While reaching the proper subcooling level, it is important to
knowthedischargelinetemperature.Thistemperatureshouldbe
atleast80ºF over ambient or refrigerant could flood back to com-
pressor.
Troubleshooting
Qualified Installer/Servicer Only
When troubleshooting, the first step should always be to check
for clean coils, clean filter(s), and proper airflow. Indoor airflow
should be 375 to 425 CFM per ton of cooling based on the size of
the outdoor unit. The most common way of establishing indoor
airflow is heating temperature rise. Indoor airflow will then be
(Heatingoutput ofequipment) /(1.1 x temp.rise).In othercases,
measurement of external static pressure is helpful. For details,
see the Installation Instructions for your indoor unit.
