When installation is completed, perform test run according to the
following procedure, and hand over the system to the customer.
Perform test run regarding indoor units one by one in order, and
confirm that the electrical wiring and the refrigerant piping are
correctly connected.

C A U T I O N
Do not operate the system until all the check points have been cleared:
• Check to ensure that the electrical resistance is more than 1 MΩ,
by measuring the resistance between ground and the terminal of the
electrical parts. If not, do not operate the system until the electrical
leakage is found and repaired. Do not impress the voltage on the
terminals for transmission 1 and 2.
• Check to ensure that the stop valves of the outdoor unit are fully
opened, and then start the system.
• Check to ensure that the switch on the main power source has been
ON for more than 12 hours, to warm the compressor oil by the oil
heater
Pay attention to the following items while the system is running:
• Do not touch any of the parts by hand at the discharge gas side,
since the compressor chamber and the pipes at the discharge side
are heated higher than 90°C.
• DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES), it
will cause a serious accident.
• Do not touch any electrical components for more than three minutes
after turning OFF the main switch
• Confirm that the gas line stop valve and the liquid line stop valve are
fully open.
• Confirm that the leakage of the refrigerant does not exist. The flare
nuts are sometimes loosened by vibration during transportation.
• Check that the refrigerant piping and the electrical wiring conform to
the same system.
• Confirm that the dip switch setting on the printed circuit board of the
indoor units and the outdoor units are correct.
• Check whether or not the electrical wiring of the indoor units and the
outdoor units are connected properly.

Confirm that field-supplied electrical components (main switch fuse,
fuse-free breaker, earth leakage breakers, wires, conduit connectors and
wire terminals) have been properly selected according to the electrical
data given in the Technical Catalogue of the unit and ensure that the
components comply with national and local codes.

N O T E
• For twin, triple and quad check the indoor unit outlet air temperature
at test run. If the temperature difference is large (aprox. 10 deg. or
more (cooling) 20 deg. or more (heating) recheck the refrigerant
piping, Installation may have some problem.
• In the case of annual cooling optional function, cut JP1 out and set
the DSW6-1 to OFF. (Individual control is not available when annual
cooling is selected).
