Part 3 Design and installation
3.1.5 Before installation
• During product unpacking and removing it from the packing case, be sure to lift it without exerting any pressure
on other parts, especially, horizontal flaps, the refrigerant piping, drain piping, and other resin parts.
• Be sure to remove a cushion (corrugated paper) located between the heat exchanger and the right air filter.
• Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect refrigerant will pre-
vent normal operation of the unit.)
• The accessories needed for installation must be retained in your custody until the installation work is completed. Do not
discard them!
• Decide upon a line of transport.
• Leave the unit inside its packaging while moving, until reaching the installation site. Where unpacking is unavoidable, use
a sling of soft material or protective plates together with a rope when lifting, to avoid damage or scratches to the unit.
• For the installation of an outdoor unit, refer to the installation manual attached to the outdoor unit.
• When using the wireless remote controller, refer to the installation manual attached to the wireless remote controller.
• Entrust installation to the place of purchase or an authorized serviceman. Improper installation could lead to leaks and in
worst cases, electric shock of fire.
• Use only parts provided with the unit or parts satisfying required specifications. Unspecified parts could cause the unit to
fall out of place, or could lead to leaks and, in the worst cases, electric shock or fire.
3.1.4 For the following items, take special care during construction and check
after installation is finished
1. Items to be checked after completion of work
• Install the indoor and outdoor units, power supply wiring and connecting wires at least 1m. away from televisions
or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1m. may not be sufficient enough to eliminate the noise.)

Items to be checked If not properly done, what is likely to occur Check
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children will not play with them. If children play with a plastic
bag which was not torn apart, they face the risk of suffocation.
