INSTALLATION INSTRUCTIONS
Step 3 - Installation of the Outdoor Unit (Cont.)
D. Install Copper Lineset
• Cut the line set to length.
• Place nut over the pipe and then flare with the R454B
flaring tool.
NOTE: Follow standard practices as dictated by the
flare tool manufacturers for creating pipe flares. When
cutting and reaming the tubing, use caution to prevent
dirt or debris from entering the tubing. Remember to
place nut over the tubing before flaring.
• To join the line set, directly align the tubing flare to the
fitting on the other pipe. Slide the nut onto the fitting
and hand tighten.
• Torque the fittings according to the specifications
shown in the torque chart below.
• Two wrenches are required to join the flare connection;
one standard wrench and one
torque wrench adjusted to the
proper settings.
• Repeat the process for attaching
the other end of the line set.
E. Leak Test
• Remove the cap on the service valve.
•
Using a tank of dry nitrogen and approved regulator,
charge the system with 150 psig of dry nitrogen using
mini split adapter to connect the valve.
•
Check for leaks at the flare fittings using soap bubbles
or another detection device. If a leak is detected,
make repairs to the fittings and recheck. If no leaks are
detected within 3 minutes, proceed.
•
Using the same tank/regulator, charge the system to
300 psig.
•
Check for leaks as earlier. If no leaks are detected within
3 minutes, proceed.
•
Using the same tank/regulator, charge the system to
500 psig.
•
Check for leaks as earlier. Keep system pressurized for
at least 20 minutes.
WARNING
Do not use acetylene, oxygen,
compressed air or any mixture containing anything other
than dry nitrogen. Use only dry nitrogen for pressure
testing. Do not use mixtures of hydrogen containing
refrigerant and air above atmospheric pressure for
pressure testing, as they may become flammable and
could result in an explosion. Refrigerant, when used as a
trace gas, should only be mixed with dry nitrogen for
pressurizing units. Failure to follow these
recommendations could result in death or serious injury
as well as equipment or property damage.

Forced fastening without careful centering may
damage the threads and cause a refrigerant leak.
Pipe Diameter ( ø ) Fastening torque
1/4” 18 N.m / 13.3 Ft.lbs
3/8” 42 N.m / 30.1 Ft.lbs
1/2” 55 N.m / 40.6 Ft.lbs
5/8” 60 N.m / 44.3 Ft.lbs
F. System Evacuation
NOTE– Do not open service valve.
• Attach a manifold gauge, micron gauge, and vacuum pump to the
suction line port using adapter AD-87 (see illustration).
• Evacuate the system to at least 350 microns.
• Close the vacuum pump valve and check the micron gauge. If
the gauge rises 150 microns in 60 seconds, the evacuation is
incomplete or there is a leak in the system. If the gauge does not
rise 150 microns in 60 seconds, the evacuation is complete.
• Once evacuation is complete, remove the adapter and hose
connection from the suction line port and replaced the cap.
