NOTICE !
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil, causing the
rubber to degrade. Failure to follow this notice
could result in damage to roof surface.
WARNING
To prevent personal injury, as well as damage to panels,
unit or structure, observe the following:
While installing or servicing this unit, carefully stow all
removed panels so that the panels will not cause injury
to personnel, objects or nearby structures. Also, take
care to store panels where they will not be subject to
damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any
weather conditions (especially wind) that may cause
panels to be blown around and damaged.
IMPORTANT !
Exhaust vents from dryers, water heaters and
furnaces should be directed away from the outdoor
unit. Prolonged exposure to exhaust gases and the
chemicals contained within them may cause
condensation to form on the steel cabinet and other
metal components of the outdoor unit. This will
diminish unit performance and longevity.
PLACEMENT
Install unit away from windows.

STEP 2 −− REFRIGERANT PIPING −− Flushing Existing Line Set & Indoor Coil
Flush the existing line set per the following instruc-
tions. For more information, refer to the Installation
and Service Procedures manual available on DaveNet. CAUTION − DO NOT attempt to flush and re−use ex-
isting line sets or indoor coil when the system contains contaminants (i.e., compressor burn out).
NOTE − When installing refrigerant lines longer than 50
feet, refer to the Refrigerant Piping Design and Fabrication
Guidelines manual available on DaveNet (Corp. 9351−L9),
or contact the Technical Support Department Product Application group for assistance.
NOTE − For new or replacement line set installation, refer
to Service and Application Note − Corp. 9112−L4 (C−91−4).
TABLE 1
REFRIGERANT LINE SET INCHES (MM)
WARNING
When using a high pressure gas such as
nitrogen to pressurize a refrigeration or air
conditioning system, use a regulator that
can control the pressure down to 1 or 2
psig (6.9 to 13.8 kPa).
WARNING
Refrigerant can be harmful if it is inhaled. Refrigerant
must be used and recovered responsibly.
Failure to follow this warning may result in personal injury
or death.

IMPORTANT !
If this unit is being matched with an approved line
set or indoor unit coil that was previously charged
with mineral oil, or if it is being matched with a coil
which was manufactured before January of 1999,
the coil and line set must be flushed prior to installation. Take care to empty all existing traps. Polyol ester (POE) oils are used in Lennox units charged with
HFC−410A refrigerant. Residual mineral oil can act
as an insulator, preventing proper heat transfer. It
can also clog the expansion device and reduce system performance and capacity.
Failure to properly flush the system per this instruction and the detailed Installation and Service Procedures manual will void the warranty.
WARNING
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, can cause fire
and/or an explosion, that could result in
property damage, personal injury or death.
WARNING
Polyol ester (POE) oils used with HFC−410A
refrigerant absorb moisture very quickly. It is very
important that the refrigerant system be kept closed
as much as possible. DO NOT remove line set caps
or service valve stub caps until you are ready to make
connections.
IMPORTANT !
Some scroll compressors have an internal vacuum
protector that will unload scrolls when suction pressure goes below 20 psig. A hissing sound will be
heard when the compressor is running unloaded.
Protector will reset when low pressure in system is
raised above 40 psig. DO NOT REPLACE COMPRESSOR.

FLUSHING LINE SET
The line set and indoor unit coil must be flushed with at least the same
3
amount of clean refrigerant that previously charged the system. Check
the charge in the flushing cylinder before proceeding.
A. 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
B
unit coil.
B. Position the cylinder of clean HCFC−22 for delivery of liquid
refrigerant and open its valve to allow liquid refrigerant to flow into
the system through the vapor line valve. Allow the refrigerant to
pass from the cylinder and through the line set and the indoor unit
coil before it enters the recovery machine.
C. After all of the liquid refrigerant has been recovered, switch the
recovery machine to vapor recovery so that all of the HCFC−22
vapor is recovered. Allow the recovery machine to pull the system
down to 0.
D. Close the valve on the inverted HCFC−22 drum and the gauge set
valves. Pump the remaining refrigerant out of the recovery
machine and turn the machine off.
