•After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
•Turn off the main power supply switch (or breaker) before the unit maintenance.
•Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
•THIS AIR CONDITIONER ADOPTSTHE NEW HFC REFRIGERANT (R410A)WHICH DOES NOT DESTROY
OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure
is approx. 1.6 times higher than that of refrigerant R22.Accompanied with the new refrigerant, refrigerating oil
has also been changed.Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does
not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force
and impurity in it.

CAUTION
When the remote controller is used for the first time, it accepts an operation approx.5 minutes after the power
supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 minute is required to start the operation by the remote
controller.
8 TEST RUN
NOTE
Do not use the forced test run for cases other than the test run because it applies an excessive load to the
devices.
How to execute a test run
Using the remote controller, operate the unit as usual.
For the procedure of the operation, refer to the attached Owner’s Manual.
A forced test run can be executed in the following procedure if the operation stops by thermo.-OFF.
(This method is limited to when wired remote controller is installed.)
In order to prevent a serial operation, the forced test run is released after 60 minutes have passed and returns to
the usual operation.
Before test run
•Before turning on the power supply, carry out the following procedure.
1) Using 500V-megger, check 1MΩ or more exists between the terminal block 1 to 3 and the earth.
If 1MΩor less is detected, do not run the unit. Do not apply to the remote controller circuit.
2) Check the valve of the outdoor unit being opened fully.
•To protect the compressor at activation time, leave power-ON for 12 hours or more be for operating.
