Caution
• Install the water discharge piping according to the steps
described in this manual, and make sure that the water
discharge is smooth, and the piping is properly insulated to
prevent condensation. Improper installation of the water
discharge piping may lead to water leakage, and damage the
indoor furniture.
• When mounting the indoor and outdoor units, make sure the
power cord is installed at a distance of at least 1 m away from
any TV or radio so as to prevent noise or interference with the
images.
• The refrigerant required for the installation is R410A. Make sure
the refrigerant is correct before installation. Incorrect refrigerant
may cause the unit to malfunction.
• Do not install the air conditioner in the following places:
1) Where there is oil or gas, such as the kitchen. Otherwise, the
plastic parts may age, fall off or water may leak.
2) Where there are corrosive gases (such as sulphur dioxide).
Corrosion in the copper pipes or welded parts may cause the
refrigerant to leak.
3) Where there are machines emitting electromagnetic waves.
Electromagnetic waves may interfere with the control
system, causing the unit to malfunction.
4) Where there is a high salt content in the air. When exposed
to air with a high salt content, the mechanical parts will
experience accelerated
compromise the service life of the unit.
5) Where there are major voltage fluctuations. Operating the
unit using a power supply system that has large voltage
fluctuations will reduce the service life of the electronic
components, and cause the unit's controller system to
malfunction.
6) Where there is a risk of leakage of flammable gases.
Examples are sites that contain carbon fibres or combustible
dust in the air, or where there are volatile combustibles (such
as diluent or petrol). The above gases may cause explosion
and fire.
7) Do not touch the fins of the heat exchanger as this may lead to
injury.
8) Some products use the PP packing belt. Do not pull or tug on
the PP packing belt when you transport the product. It will be
dangerous if the packing belt breaks.
9) Note the recycling requirements for nails, wood, carton and
other packaging materials. Do not discard these materials
directly as these may lead to bodily harm.
10)Tear up the packaging bag for recycling to prevent children
from playing with it, and leading to suffocation.
11)The appliance shall not be installed in the laundry.
• When the product is used for comercial application. This
appliance is intended to be used by expert or trained users in
shops, in light industry and on farms, or for commercial use by lay
persons,the sound pressure level is below 70 dB(A).
