Procedure" on next page.

WARNING:
Do not operate the system until all the check points
have been cleared:
Check to ensure that the electrical resistance is
-
Ω
more than 1 M , 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

INSTALLATION OF REMOTE CONTROLLER
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 as shown in
the chapter ELECTRICAL WIRING".

CAUTION:
Confirm that field-supplied electrical components
(main switch fuse, fuse-free breaker, earthleakage
breakers, wires, conduit connectors and wire
terminals) have been properly selected according to
the electrical data given in the Technical Catalog of
the unit and ensure that the components comply with
national and local codes.
