Note on Pipe Length
Connection Instructions – Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
Measure the distance between the indoor
and outdoor units.
Using a pipe cutter, cut the pipe a little
longer than the measured distance.
Make sure that the pipe is cut at a perfect
90° angle.
Oblique Rough Warped

Maximum Length and Drop Height of Refrigerant Piping per Unit Model
DO NOT DEFORM PIPE WHILE CUTTING
WARNING
WHEN CONNECTING REFRIGERANT PIPING, DO NOT LET SUBSTANCES OR GASES OTHER THAN
THE SPECIFIED REFRIGERANT ENTER THE UNIT. THE PRESENCE OF OTHER GASES OR
SUBSTANCES WILL LOWER THE UNIT’S CAPACITY AND CAN CAUSE ABNORMALLY HIGH
PRESSURE IN THE REFRIGERATION CYCLE. THIS CAN CAUSE EXPLOSION AND INJURY.
The length of refrigerant piping will aect the performance and energy eciency of the unit. Nominal
eciency is tested on units with a pipe length of 5 meters (16.5ft). A minimum pipe run of 3 metres is
required to minimise vibration & excessive noise.
Be extra careful not to damage, dent; or deform the pipe while cutting. This will drastically reduce
the heating eciency of the unit.

Evacuation Instructions
Air Evacuation
29
NOTE
:
PREPARATIONS AND PRECAUTIONS
Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can
damage the air conditioner, reduce its eciency and cause injury. Use a vacuum pump and manifold
gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the
system. Evacuation should be performed upon initial installation or if the unit is relocated.
BEFORE PERFORMING EVACUATION
Make sure the connective pipes between the indoor and outdoor units are connected properly.
Check to make sure all wiring is connected properly.
Connect the charge hose of the manifold
gauge to the service port on the outdoor unit’s
low pressure valve.
Connect another charge hose from the
manifold gauge to the vacuum pump.
Open the low pressure side of the manifold
gauge. Keep the high pressure side closed.
Turn on the vacuum pump to evacuate the
system.
Run the vacuum pump for at least 15 minutes,
or until the compound meter reads -76cmHG
(-10 Pa).
Close the Low Pressure side of the manifold
gauge and turn o the vacuum pump.
Wait for 5 minutes, then check that there
has been no change in system pressure.

If there has been a change in system pressure, refer to the
Gas Leak Check section for information on how to check
for leaks.
If there is no change in system pressure, unscrew the cap
from the packed valve (high pressure valve).
Insert hexagonal wrench into the packed valve(high
pressure valve) and open the valve by turning the wrench
in a 1/4 counter clockwise turn. Listen for gas to exit the
system, then close the valve after 5 seconds.
Watch the Pressure Gauge for one minute to make sure
that there is no change in pressure. The Pressure Gauge
should read slightly higher than atmospheric pressure.
Remove the charge hose from the service port.
Using a hexagonal wrench, fully open both the high
pressure and low pressure valves.
Tighten valve caps on all three valves (service port, high
pressure and low pressure) by hand. You may tighten it
further using a torque wrench if needed.
NOTE
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. For example, in North America, the standard pipe length is 7.5m (25’).
In other areas, the standard pipe length is 5m (16‘). The refrigerant should be charged from the service
port on the outdoor unit’s low pressure valve. The additional refrigerant to be charged can be
calculated using the following formula:
