Pumping down refrigerant
WARNING
• After installing the product, be sure to perform leak tests
on the piping connections. After pumping down refrigerant
to inspect or relocate the outdoor unit, be sure to stop the
compressor and then remove the connected pipes.
– Do not operate the compressor for pump down when
the refrigerant circuit is open due to a refrigerant
leakage or a disconnected (or incorrectly connected)
pipe. Failure to do so may cause air to flow into the
compressor and a too high pressure can develop
inside the refrigerant circuit, leading to an explosion or
product malfunction.
Pump-down is an operation intended to collect all the system
refrigerant in the outdoor unit. This operation must be carried
out before disconnecting the refrigerant pipe in order to avoid
refrigerant loss to the atmosphere.
1 Turn the system on in cooling with fan operating at high
velocity and then let the compressor run for more than 5
minutes. (Compressor will immediately start, provided 3
minutes have elapsed since the last stop.)
2 Release the valve caps on High and Low pressure side.
3 Use L-wrench to close the valve on the high pressure side.

5 Stop operation of the air conditioner by pressing the
(Power) button on the indoor unit or remote control.
6 Disconnect the pipes.

Relocating the indoor and outdoor units
1 Pump down refrigerant. See Pumping down refrigerant
on page 32.
2 Disconnect the power supply only after rendering the
system powerless from the mains power.
3 Disconnect the assembly cable from the indoor and
outdoor units.
4 Remove the flare nuts connecting the indoor units and
the pipes. At this time, cover the pipes of the indoor
unit and the other pipes using a cap or vinyl plug to
avoid foreign material entering.
5 Disconnect the pipes connected to the outdoor units. At this
time, cover the valve of the outdoor units and the other pipes
using a cap or vinyl plug to avoid foreign material entering.
Note: Make sure you do not bend the connection pipes in
the middle and store together with the cables.
6 Move the indoor and outdoor units to a new location.
7 Remove the mounting plate for the indoor unit and
move it to a new location.
