4. INSTALLATION SITE
Regarding places for installation
• Is the air conditioner installed at a well-venti-
lated place where there are no obstacles
around?
• Do not use the air conditioner in the following
places.
a.Filled with much mineral oil such as cutting oil
b.Where there is much salt such as a beach area
c.Where sulfured gas exists such as a hot-spring
resort
d.Where there are considerable voltage fluctua-
tions such as a factory or plant
e.Vehicles and vessels
f. Where there is much spray of oil and vapor
such as a cookery, etc.
g.Where there are machines generating electro-
magnetic waves
h.Filled with acid and/or alkaline steam or vapor
Regarding wiring
• All wiring must be performed by an authorized
electrician.
To do wiring, ask your dealer. Never do it by your-
self.
• Make sure that a separate power supply circuit
is provided for this air conditioner and that all
electrical work is carried out by qualified per-
sonnel according to local laws and regulations.
Pay attention to running noises, too
• Are the following places selected?
a. A place that can sufficiently withstand the
weight of the air conditioner with less running
noises and vibrations.
b. A place where the hot wind discharged from the air
outlet of the outdoor unit and the running noises do
not cause a nuisance to neighbours.
• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
• If abnormal noises occur in use, stop the oper-
ation of the air conditioner, consult your dealer.
Regarding drainage of drain piping
• Is the drain piping carried out properly to
ensure complete drainage?
If drain piping is not carried out properly, dirt and
debris may be accumulated in the drain pipe and
cause water leakage. If it occurs, stop the air con-
ditioner and consult with your dealer for assis-
tance.
5. OPERATION PROCEDURE
Read the operation manual that came with
the remote controller.
•
To protect the unit, turn on the main power switch
6 hours before operation.
•
If the main power supply is turned off during oper-
ation, operation will restart automatically after the
power turns back on again.
6. OPERATION CHARACTERISTICS
[CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)]
•
After continued operation at a downward airflow
direction, operate the air conditioner using a dif-
ferent direction setting for a period of time to pre-
vent condensation on the airflow flaps. (The
remote controller displays the airflow direction
that is set.)
•
If the COOLING OPERATION is used when the
indoor temperature is low, frost forms on the heat
exchanger of the indoor unit. This can decrease
the cooling capacity. In this case, the system
automatically switches to DEFROST OPERA-
TION for a while.
During DEFROST OPERATION, the low airflow
rate is used to prevent the discharge of melt
water. (The remote controller displays the airflow
rate that is set.)
•
When the outdoor temperature is high, it takes
some time until the indoor temperature reaches
the set temperature.
[CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)]
START OF OPERATION
•
It generally takes a longer time for HEATING
OPERATION to reach the set temperature com-
pared to COOLING OPERATION. It is advisable
to start operation in advance using TIMER OPER-
ATION.
Perform the following operation to prevent heat-
ing capacity decrease and discharge of cool air.
