Recommended line length is 50' or less. If more than 50'
linesetisrequired,contactTechnicalServicesat1-800-448-
5872.
Table2 shows the diameters forline setsup to 100'although
vertical lift applications and trapping requirements need to
be reviewed with Technical Services for line sets over 50'.
Installing Refrigerant Line
During the installation of an air conditioning system, it is
important to properly isolate the refrigerant line to prevent
unnecessary vibration. Line set contact with the structure
(wall, ceiling, or floor) may cause objectionable noise when
vibration is translated into sound.As a result, more energy
or vibration can be expected. Close attention to line set
isolation must be observed. If refrigeration lines are routed
through a wall, seal and isolate the opening so vibration is
not transmitted to the building.
Following are some points to consider when placing and
installing a high-efficiency outdoor unit:
Placement
Beaware that somelocalitiesareadoptingsoundordinances
based on how noisy the unit is at the neighbor’s home, not
at the original installation. Install the unit as far as possible
from the property line. When possible, do not install the unit
directly outside a bedroom window. Glass has a very high
level of sound transmission. Figure 4 shows how to place
the outdoor unit and line set to reduce line set vibration.
Line Set Isolation
Illustrationsonthe following pagesdemonstrateprocedures
which ensure proper refrigerant line set isolation. Figure 5
shows how to install line sets on horizontal runs. Figure 6
shows how to make a transition from horizontal to vertical
and Figure 7 on page 6 shows how to install line sets on
vertical runs.

Flushing Existing Line Set and Indoor Coil
This procedure should not be performed on systems
which contain contaminants, such as compressor
burn out.
Required Equipment
The following equipment is needed to flush the existing line
set and indoor coil (see Figure 8): Two clean R22 recovery
bottles, an oil-less recovery machine with a “pump down”
feature, and two sets of gauges (one for use with R22 and
one for use with R410A).
Flushing Procedure
IMPORTANT:Thelinesetand/orindoorcoilmustbeflushed
with at least the same amount of refrigerant that previously
chargedthe system.Checkthecharge intheflushingcylinder
before flushing the unit.
1. Remove existing R22 refrigerant using the appropriate
procedure.
If the existing outdoor unit is not equipped with shutoff
valves, or if the unit is not operational AND the existing
R22 refrigerant will be used to flush the system:
Disconnectallpowertotheexistingoutdoorunit.Connect
theexistingunit,acleanrecoverycylinder,andtherecovery
machine according to the instructions provided with the
recovery machine. Remove all R22 refrigerant from the
existing system. Refer to the gauges after shutdown to
confirm that the entire system is completely void of
refrigerant. Disconnect the liquid and suction lines from
the existing outdoor unit.
If the existing outdoor unit is equipped with manual
shutoff valvesAND new R22 refrigerant will be used to
flush the system:
Start the existing R22 refrigerant system in cooling mode
and close the liquid line valve. Pump all the existing R22
refrigerant back into the outdoor unit.
(Itmaybenecessarytobypassthe lowpressureswitches
to ensure complete refrigerant evacuation.)
When flushing existing line set and/or indoor coil, be sure
to empty all existing traps. Residual mineral oil can act as
aninsulator,preventingproperheattransfer.Itcanalsoclog
thethermalexpansionvalve,reducingsystemperformance
andcapacity.Failuretoproperlyflushsystem asexplained
inthese instructionswillvoid warranty.
CAUTION
Figure 8
Flushing Connections
Note: The inverted R22 cylinder must contain at least the
same amount of refrigerant as was recovered from
the existing system.

When the low side system pressures reach 0 psig, close
thesuction line valve.Disconnectall power to theexisting
outdoorunit.Refertothegaugesaftershutdowntoconfirm
that the valves are not allowing refrigerant to flow back
into the low side of the system. Disconnect the liquid and
suction lines from the existing outdoor unit.
2. Remove the existing outdoor unit. Set the new R410A
unitandfollowthebrazingconnection procedureoutlined
previously on this page to make line set connections.
Do not install the R410Athermal expansion valve at
this time.
3. Makelowvoltageandlinevoltageconnectionstothe new
outdoor unit. Do not turn on power to the unit or open
the outdoor unit service valves at this time.
4. Removetheexisting R-22 refrigerant flowcontrolorifice
or thermal expansion valve before continuing with
flushing procedures. R-22 flow control devices are not
approved for use with R410A refrigerant and may
prevent proper flushing. Use a field-provided fitting to
reconnect the lines.
5. Remove the pressure tap valve cores from the
4SCU14LE unit’s service valves. Connect an R-22
cylinder with clean refrigerant to the suction service
valve.Connectthe R-22 gauge set to the liquidlinevalve
andconnectarecovery machine with an empty recovery
tank to the gauge set.
6. Set the recovery machine for liquid recovery and start
the recovery machine. Open the gauge set valves to
allow the recovery machine to pull a vacuum on the
existing system line set and indoor coil.
7. Invert the cylinder of clean R-22 and open its valve to
allow liquid refrigerant to flow into the system through
thesuction linevalve.Allow the refrigerantto passfrom
the cylinder and through the line set and the indoor coil
before it enters the recovery machine.
8. After all of the liquid refrigerant has been recovered,
switch the recovery machine to vapor recovery so that
all of the R-22 vapor is recovered. Allow the recovery
machine to pull a vacuum on the system.
NOTE: A single system flush should remove all of the
mineral oil from the existing refrigerant lines and indoor
coil. A second flushing may be done (using clean
refrigerant) if insufficient amounts of mineral oil were
removedduringthefirstflush.Aftereach system flush,
allow the recovery machine to pull a vacuum on the
system at the end of the procedure.
9. Close the valve on the inverted R22 cylinder and the
gauge set valves. Pump the remaining refrigerant out
of the recovery machine and turn the machine off.
10. Use nitrogen to break the vacuum on the refrigerant
lines and indoor coil before removing the recovery
machine, gauges, and R22 refrigerant drum. Re-install
pressure tap valve cores into the 4SCU14LE unit’s
service valves.
11. Install a thermal expansion valve kit (sold separately)
that is approved for use with R410A refrigerant in the
liquid line at the indoor coil.
Refrigerant Metering Device
4SCU14LE units are designed for use withTXV systems only.
Expansion valves equipped with Chatleff-type fittings are
availablefromthemanufacturer.SeeTable 3 for properTXV
for each unit.
To install an expansion valve (see Figure 9):
1. Separate thedistributor assembly andremovethe piston
orifice and used teflon seal. Insert nozzle end of the
expansion valve along with a new teflon seal into the
distributorandtightento20–30ft.lbs.Usebackupwrench
onall wrenchflats.Overtighteningwill crush the teflon
seal and may cause a leak.
2. Attach liquid line portion of distributor assembly along
with new teflon seal to the inlet of the expansion valve.
Tighten to 20 – 30 ft. lbs. Use backup wrench on all
wrenchflats.Overtightening will crush the teflon seal
and may cause a leak.
3. Connectthe external equalizerlineto the equalizerport
on the suction line and tighten to 8 ft. lbs.
4. Strap the superheat sensing bulb to the suction header.
If installing an expansion valve on an indoor coil that
previouslyusedafixed orifice, be sure to remove the existing
fixedorifice. Failure toremovea fixed orificewheninstalling
an expansion valve to the indoor coil will result in improper
operation and damage to the system.

Leak Testing
After the line set has been connected to the indoor and
outdoor units, the line set connections and indoor unit must
be checked for leaks.
Using an Electronic Leak Detector
1. Connect the high pressure hose of the manifold gauge
set to the suction valve service port. (Normally the high
pressure hose is connected to the liquid line port;
however, connecting it to the suction ports helps to
protectthe manifold gaugesetfrom damage causedby
high pressure.)
2. With both manifold valves closed, connect the cylinder
of R410A refrigerant. Open the valve on the R410A
cylinder(vapor only).
3. Open the high pressure side of the manifold to allow
R410Ainto the linesetand indoor unit.Weighin atrace
amount of R410A. (A trace amount is a maximum of 2
oz. of refrigerant or 3 lbs. pressure.) Close the valve on
the R410A cylinder and the valve on the high pressure
side of the manifold gauge set. Disconnect the R410A
cylinder.
4. Connectacylinderofnitrogenwithapressureregulating
valvetothecenterport of the manifold gaugeset. When
using high pressure gas such as nitrogen for this
purpose, be sure to use a regulator that can control
the pressure down to 1 or 2 psig.
5. Adjustnitrogenpressure to 150psig.Open the valveon
the high side of the manifold gauge set to pressurize
the line set and the indoor coil.
6. After a short period of time, open a refrigerant port to
make sure that an adequate amount of refrigerant has
been added for detection (refrigerant requirements will
vary with lengths). Check all joints for leaks. Purge
nitrogen and R410A mixture. Correct any leaks and
recheck.

(90°).
Fire, Explosion, and Personal Safety Hazard.
Failure to follow this warning could result in damage,
personal injury, or death.
Never use oxygen to pressurize or purge refrigeration
lines. Oxygen, when exposed to a spark or open flame,
cancause damagebyfireand/oran explosion,thatcould
result in personal injury or death.

Evacuation
Evacuating the system of noncondensables is critical for
proper operation of the unit. Noncondensables are defined
as any gas that will not condense under temperatures and
pressures present during operation of an air conditioning
system. Noncondensables and water vapor combine with
refrigeranttoproducesubstancesthatcorrodecopperpiping
and compressor parts.
Usea thermocouple orthermistorelectronic vacuum gauge
that is calibrated in microns. Use an instrument that reads
down to 50 microns.
Do not use a compressor to evacuate a system. Avoid
deep vacuum operation. Extremely low vacuums can
cause internal arcing and compressor failure. Danger
ofequipment damage.Damagecausedbydeepvacuum
operation will void warranty.
WARNING
1. Connect the manifold gauge set to the service valve
ports as follows:
• Low pressure gauge to suction line service valve
• High pressure gauge to liquid line service valve
2. Connect micron gauge.
3. Connect the vacuum pump (with vacuum gauge) to the
center port of the manifold gauge set.
4. Open both manifold valves and start vacuum pump.
5. Evacuate the line set and indoor unit to a minimum of 500
micronsorlower.Duringtheearlystagesofevacuation,itis
desirabletoclosethemanifoldgaugevalveatleastonceto
determine if there is a rapid rise in pressure.Arapid rise in
pressure indicates a relatively large leak. If this occurs, the
leak testing procedure must be repeated.
6. When 500 microns or lower is maintained, close the
manifold gauge valves, turn off the vacuum pump, and
disconnectthemanifoldgaugecenter port hose from the
vacuum pump. Attach the manifold gauge center port

6. Theoutdoortemperature willdeterminewhich charging
method to use. Proceed with the appropriate charging
method.
Charge Using Weigh-In Method
If the system is void of refrigerant, or if the outdoor ambient
temperature is cool, first locate and repair any leaks then
use the weigh-in method to charge the unit.
1. Recover the refrigerant from the unit.
2. Conduct a leak check, then evacuate as previously
outlined.
3. Weighinthechargeaccordingtothetotalamountshown
on the unit nameplate.
If weighing facilities are not available or if unit is being
charged during warm weather, follow one of the other
procedures outlined below.
Charge Using Subcooling Method –
Outdoor Temperatures 65°F or Above
When the outdoor ambient temperature is 65°F or above,
the subcooling method can be used to charge the unit.
1. With the manifold gauge hose on the liquid service port
and the unit operating stably, use a digital thermometer
to record the liquid line temperature.
2. At the same time, record the liquid line pressure reading.
3. Use the temperature/pressure chart (Table 5) to
determine the saturation temperature for the liquid line
pressure reading.
4. Subtract the liquid line temperature from the saturation
temperature (according to the chart) to determine

Charge Using Approach Method –
Outdoor Temperatures 65°F or Above
The following procedure is intended as a general guide and
isforuse on expansionvalvesystems only. For bestresults,
indoor temperature should 70°F to 80°F. Monitor system
pressures while charging.
1. Record outdoor ambient temperature using a digital
thermometer.
2. Attach high pressure gauge set and operate unit for
several minutes to allow system pressures to stabilize.
3. Compare stabilized pressures with those provided in
Table 8. Minor variations in these pressures may be
expected dueto differencesin installations. Significant
differences could mean that the system is not
properly charged or that a problem exists with some
componentin the system. Pressureshigherthanthose
listedindicatethat the system is overcharged. Pressures
lower than those listed indicate that the system is
undercharged. Verify adjusted charge using the
approach method.
4. Use the same digital thermometer to check liquid line
temperature.
5. Subtracttheoutdoorambienttemperaturefromtheliquid

6. Comparethe approach valuewiththose shown inTable
7. If the values to do not agree with those provided in
Table 7, add refrigerant to lower the approach
temperature or recover refrigerant from the system to
increase the approach temperature.
Check Charge Using Normal Operating Pressures
Use Table 8 to perform maintenance checks. Table 8 is not
a procedure for charging the system. Minor variations in
these pressures may be due to differences in installations.
Significant deviations could mean that the system is not
properly charged or that a problem exists with some
component in the system.
Approach Values for TXV Systems
Approach value is the liquid line temperature minus the
outdoor ambient temperature (±1°F).
NOTE: For best results, use the same digital thermometer
to check both outdoor ambient and liquid temperatures.
