Step 8 Connecting up and removing air
in the circuit
CAUTION
ŷ When installing, make sure there is no leakage. When
recovering the refrigerant, ground the compressor
first before removing the connection pipe. If the
refrigerant pipe is not properly connected and the
compressor works with the service valve open, the
pipe inhales the air and it makes the pressure inside
of the refrigerant cycle abnormally high. It may cause
explosion and injury.
The air in the indoor unit and in the pipe must be
evacuated. If air remains in the refrigerant pipes, it will
affect the compressor either reduce cooling/heating
capacity or lead to a malfunction. Refrigerant for air
purging is not charged in the outdoor unit. Use Vacuum
Pump as shown at the right figure.
1 Connect each assembly pipe to the appropriate valve
on the outdoor unit and tighten the flare nut.
2 Referring to the illustration below, tighten the flare
nut on section D first manually and then with a
torque wrench, applying the following torque.

ŷ Make sure that pressure gauge shows -0.1 MPa
(-76 cmHg) after about 10 minutes. This procedure
is very important to avoid a gas leak.
ŷ Turn off the vacuum pump.
ŷ Remove the hose of the low pressure side of
manifold gauge.
6 Open the stop valve of both liquid and gas sides.
7 Mount the valve stem nuts and the service port
cap to the valve, and tighten them at the torque of
NJIŷFPZLWKDWRUTXHZUHQFK
8 Check for gas leakage.
ŷ At this time, especially check for gas leakage from
the 3-way valve’s stem nuts(A port), and from the
service port cap.
CAUTION
ŷ Connect the indoor and outdoor units using pipes
with flared connections (not supplied). For the lines,
use insulated, unwelded, degreased and deoxidized
copper pipe, (Cu DHP type to ISO 1337 or UNI EN
12735-1), suitable for operating pressures of at least
4200 kPa and for a burst pressure of at least 20700
kPa. Copper pipe for hydro-sanitary applications is
completely unsuitable.
ŷ For sizing and limits (height difference, line length,
max. bends, refrigerant charge, etc.) see “Connecting
refrigerant pipe section”.
Step 9 Adding refrigerant (R-410A)
ŷ The outdoor unit is loaded with sufficient refrigerant
for the standard piping. Thus, refrigerant must be
added if the piping is lengthened. This operation
can only be performed by a qualified refrigeration
specialist. To determine the quantity of refrigerant
charge, see Calculating the quantity of refrigerant to
add on page 20.
1 Check if the stop valve is closed completely.
2 Charge the refrigerant through the service port of the
liquid stop valve.
NOTE
ŷ Do not charge the refrigerant through the service
port of the gas stop valve.
3 If you have any difficulty charging the refrigerant as
described in the steps above, take the following steps:
a Open the liquid stop valve and gas stop valve.
b Operate the air conditioner by pressing the K2
key on the outdoor unit PCB.
c After about 30 minutes, charge the refrigerant
through the service port of the gas stop valve.
