1. Precautions

Using the level, check that the installation of the outdoor unit is horizontal. If not, this may result in failure.
To operate the system, individual addresses must be set for the outdoor and indoor units.
The outdoor unit address must be set manually; however, the indoor unit addresses are set automatically for each
refrigerant system.
After the addresses are set, the indoor unit addresses must be checked in order to identify each indoor unit.
After the addresses have been checked, apply unit number labels to each indoor unit and outdoor unit. These will be
necessary for later maintenance.
Follow the procedure below and perform the work correctly.

2. Test Run Procedure

Start
Set the type of fuel gas. (For Band P (LPG))
Check the date and time
Check the initial settings ((1) Model, (2) Power).
Check and set the type of engine gas
(Supplied as fuel).
Set the number of connected indoor units.
Check wiring arrangement of control cables
between indoor and outdoor units.
Set the outdoor unit address.*
(*The address indicates the unit serial number.)
Set final terminator status.
Re-check the pre-test run check items.
Ensure that tube connections are securely attached, and that
•
there are no leaks.
Ensure that shut-off valves (service valves) are open.
•
If a compressor is run while a shut-off valve (service valve)
is closed, the pressure will become abnormally high and
there is a risk of damage to the parts of the compressor, etc.
Additionally, if there is a leak in the connection parts, the
pressure will become even more abnormally high because of
sucked-in air, etc. and there is a risk of rupturing and injury.
