2-4 NOTE TO THE INSTALLER
Be sure to instruct customers how to properly operate (especially cleaning filters, operating different
functions, and adjusting the temperature) by having them carry out operations by themselves while reading
the manual literally.
3. SELECTING INSTALLATION SITE
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
(1) Select an installation site where the following conditions are fulfilled and that meets with your cus-
tomer’s approval.
• Where optimum air distribution can be ensured.
• Where the floor is strong enough to withstand the
weight and vibration of the indoor unit.
• Make sure the floor is level. (Vibration and abnormal
noise may be generated.)
• Where nothing blocks the air inlet and outlet, and
where sufficient clearance for maintenance and
service can be ensured. (Refer to Fig.2)
(If not ensured, the capacity may drop due to short
circuit.)
• Where condensate can be properly drained.
• Where piping between indoor and outdoor units is
possible within the allowable limit. (Refer to the
installation manual for the outdoor unit.)
• Where there is no risk of flammable gas leakage.
(2) Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from
televisions or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to elimi-
nate noise.)
Items to be checked Check
Has the field setting done (as necessary)?
Did you attach the control box lid, the air filter, and suction grille?
Does the cold air (warm air) blow properly during the cooling (heating) operation?
Did you explain about operations while showing the operation manual to your customer?
Did you explain the cooling, heating, dry, and automatic cooling/heating operations described
in the operation manual?
Did you explain what the set airflow rate is when setting the airflow rate at thermostat off to the
customer?
Is the emergency switch (EMG.) of the printed circuit board turned ON? At delivery from the
factory, it is set to normal (NORM).
Is the suction thermistor installed at its original position (bell mouth) when the optional adapter
installation box is installed?
Did you hand the operation manual over to your customer? (Please hand over the installation
manual as well.)
Since the items with WARNING and CAUTION marks in the operation manual, if not
observed, may cause injuries and/or material damages. Therefore, in addition to the general usage,
it is necessary to explain them to the customer and also to ask the customers to thoroughly read
them. Accordingly, it is necessary that you make a full explanation about the described contents
and also ask your customers to read the operation manual.
