a blue ridge ductless mini-split is one
of the most efficient ways to heat and
cool your home
they're perfect choice for additions
garages or rooms were ductwork is
unavailable
many splits are energy-efficient quiet
and easy to install the mini split is
comprised of two units the indoor air
handler and the outdoor condenser the
components are connected by copper
tubing which allows a necessary
refrigerant to circulate a handheld
remote gives you thermostatic control
over the system before you begin
installation make sure you have all the
parts you need according to the
installation manual inspect the various
components to ensure there are no
defects before installation work begins
you can complete the majority of the
installation yourself however the last
ten percent of the work should be
completed by a trained professional
proper installation is crucial to
achieving maximum performance and energy
savings the unit can produce it's
essential to carefully read the Blue
Ridge owners manual paying particular
attention to safety precautions and
procedures before you start ensure you
have the right tools for the job
standard tools needed include the
following adjustable wrench torque
wrench hex keys or allen wrenches a
drill and drill bits a hole saw a
utility knife a wire cutter and stripper
phillips and flat blade screw drivers a
level safety glasses and work gloves
your professional installer should bring
the rest of the required tools including
manifold gauges vacuum pump flaring tool
and a dry nitrogen tank with regulator
to begin installation choose a spot on
the wall surface where you'd like the
unit to be secured location should be
free of obstructions near the air inlet
and outlet and should be at least six
feet from the floor refer to the manual
for more tips on choosing a location
remove the wall bracket from the back of
the mini split indoor air handler hold
the bracket in place use a level to
ensure it is horizontally level then
mark the screw holes with a pencil drill
the marked holes to create a pilot hole
and use appropriate sized self-tapping
screws with anchors to fix the wall
mounting frame finally checked to ensure
the wall mounting frame is firmly
attached by pulling on it
now you will create a hole in the wall
to allow refrigerant lines control wires
and condensation drain to go outside the
hole is usually two-and-a-half to three
inches using a hole saw bit drill the
hole making sure to angle downward to
the outside for proper condensate
drainage the wall mounted air handler
ships with the refrigerant piping on the
right and the drain tube on the left but
can be configured to your particular
application in this case we will move
the condensate drain tube from the left
to the right
this requires removing the outer cover
of the air handler open the service
hatch and remove the four screws across
the front
in the fifth screw in the center bottom
turn the unit over and release the for
locking tabs
carefully lift off the cover and turn
the unit over to expose the drain
connection
unfasten the retaining clip for the
drain hose and remove the drain hose
next locate the rubber drain plug on the
right side remove it and use it to plug
the left side drain replace the hose on
the right side drain and fast in the
retaining clip prepared to install the
control wire by removing the wire cover
and wiring clip
push the color-coded multi-conductor
wire through the inlet hole on the back
of the air handler and pull a few inches
through the front leave the cover open
you'll make the wiring connections later
now carefully unfold the refrigerant
pipe making sure not to crimp the copper
tube in the process bundle the control
wire refrigerant lines and drain tubing
together with electrical tape to make
sure it'll fit easily through the wall
and installation support bracket is an
optional tool that helps by acting as a
second set of hands holding the air
handler in place while you make the
inside connections and prepare to mount
the unit lift the unit into place and
carefully past the bundled pipes and
wires through the wall opening place the
air handler on the wall mount making
sure it is firmly secured and your
refrigerant line condensate tube and
electrical cables are completely through
the wall now you can make the
multi-conductor wire connections after
cutting the length and stripping the
wire make the connections using a
screwdriver replace the wiring clip
wiring cover and close the front cover
you're not ready to install the outdoor
heat pump condenser choose the outdoor
units location based on your home
structure local codes and convenience of
installation you can place the unit on a
pad mounted on an exterior wall using
brackets or place it on a rooftop we're
using a pad the simplest and easiest
method the outside unit should be
securely mounted with bolts through the
footholds before making any connections
with the condenser securely mounted you
can make your outside connections the
air handler unit comes pressurized with
nitrogen you'll hear this harmless gas
release when you remove the plug
connector flared copper ends of the line
set to the pipe joint connected to the
air handler using the adjustable wrench
to hold the piping joint and prevent
twisting place the torque wrench on the
Union not and tighten to the setting
specified the manual
next connect the drain hose by push-fit
and secure with tape
fully been the to bundle to be flush
with the wall making sure not to crimp
the copper or drain tubing lines that
covers are an optional accessory that
hides the appearance of refrigerant
lines and control wires mount the
backing to your exterior wall and once
the lines are run snap the covers in
place
next remove the panel that covers the
refrigerant valves and wiring
connections some models may already have
the valves exposed remove the protective
screw caps from the valves now you can
connect the pipe joint of the outdoor
unit to the copper line set
start the Union up by hand then use the
torque wrench tightening to the
specifications in your manual
next connect the multi-conductor wire
that has run from the indoor air handler
to the Associated terminals on the
outdoor unit double check the color
coding to ensure the wires have been
connected correctly a trained
professional is recommended to complete
the installation at this point if the
copper pipes are not flare ready or if
you wish to call your line set to a
shorter lengths you will need to use a
flare tool to create a new flair
connection use a pipe cutter to cut the
copper pipe to the desired length and a
shaper to deeper the cut
be sure to put your Union not in place
first then insert the end of the pipe
into a flare tool improper flaring is
the main reason for refrigerant leaks
refer to your installation manual for
more detail and making proper flare
connections make sure the flare
connection is not tilted cracked or
otherwise damaged before connecting the
refrigerant system must be completely
sealed in order for the system to
perform properly start with a pressure
test to check for leaks using a
yellowjacket adapter will allow you to
connect standard service equipment to
the mini split service ports use dry
nitrogen and pressurize the line set and
air handler to 100 to 200 PSIG then
using a soap bubble solution spray down
all of the flare joints and watch for
bubbles to appear if bubbles are present
tighten the Union not or if necessary
reflect the copper next the technician
will use a vacuum pump engages to remove
all air and moisture prior to releasing
refrigerant into the lines
after the vacuum is complete close the
manifold gauge valve
use an adjustable wrench to remove the
service valve caps and use an Allen
wrench or hex key to fully open both
service valves releasing refrigerant
into the system the condenser requires
220-volt power from a dedicated circuit
on your breaker panel run through an
exterior mounted manual disconnect box a
qualified technician should install the
circuit breaker disconnect box and make
a high-voltage connection to the
condenser with the refrigerant released
and all high and low voltage connections
complete it's time to power up the
system and do the initial startup start
the system with the remote and check for
proper operation
