Test Operation
During test operation, the outdoor units and the indoor units will start up:
Make sure that the preparations of all indoor units are finished (field piping, electrical wiring, air
purge, etc.). See installation manual of the indoor units for details.
Caution
Do not insert fingers, rods or other objects into the air inlet or outlet. When the fan is rotating at high
speed, it will cause injury.
Caution
Do not perform the test operation while working on the outdoor units (multi system) and the
indoor units.
When performing the test operation, not only the outdoor unit, but the connected indoor unit will
operate as well. Working on an indoor unit while performing a test operation is dangerous.
Caution
 During tests never pressurize the appliances with a pressure higher than the maximum
 If refrigerant gas leaks, ventilate the area immediately. Toxic gas may be produced if refrigerant
 Never directly touch any accidental leaking refrigerant. This could result in severe wounds
 Test run is possible for ambient temperatures between 23°F and 95°F (−5°C and 35°C).
Caution
DO NOT TOUCH PIPING AND INTERNAL PARTS
Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant
piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if
you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature
or, if you must touch them, be sure to wear proper gloves.
Caution
ELECTRICAL SHOCK
Switch off all power supply before removing the electrical component box service panel or before
making any connections or touching electrical parts.
Do not touch any switch with wet fingers. Touching a switch with wet fingers can cause electrical
shock. Before touching electrical parts, turn off all applicable power supply.
To avoid electric shock, be sure to disconnect the power supply 1 minute or more before servicing
the electrical parts. Even after 1 minute, always measure the voltage at the terminals of the main
terminal, main circuit capacitors or electrical parts and, before touching, be sure that those voltages
are 50 V DC or less.
When service panels are removed, live parts can easily be touched by accident. Never leave the
unit unattended during installation or servicing when the service panel is removed.
Provide a logbook and machine card.
In accordance with the applicable legislation, it may be necessary to provide a logbook with the
equipment containing at least: information on maintenance, repair work, results of tests, stand-by
periods, etc.
INFORMATION
Note that during the first running period of the unit, required power input may be higher. This
phenomenon originates from the compressor that requires a 50 hour run elapse before reaching
smooth operation and stable power consumption. Reason is that the scroll is made out of iron and
that it takes some time to smooth the surfaces that make contact.
NOTICE
To protect the compressor, be sure to turn on the power supply 6 hours before starting operation.
