Installing the unit in the following places may cause it to
malfunction (please enquire if it is unavoidable):
Places that contain mineral oil such as machine oil for
cutting.
Places with high salt content in the air such as the sea.
Areas like hot springs where there are corrosive gases like
sulphur gases.
Factories with major voltage fluctuations in the power
supplies.
Places like a car or cabin room.
Areas filled with cooking oil and gas like kitchens.
Places where strong electromagnetic waves are present.
Places where flammable gases or materials are present.
Areas where there is evaporation of acid or alkaline gases.
Other special environmental conditions.
CAUTION
Choose the correct move-in path.
Carry the device in its original package.
Electrical insulation measures can be taken in accordance
with relevant technical specifications of electrical equipment if
the air conditioner is to be installed onto the metal part of a
building.
If the height difference is greater than the allowed level
difference, it is recommended to place the ODU above the
IDU.
CAUTION
The IDU should be handled with care, and it should not be
subjected to heavy pressure.
After the IDU is installed, in case of construction, the IDU
should be protected to prevent garbage and dust from falling
into the unit.
The fan should be rotated before the test run. Make sure that
there is no abnormal friction before powering on the unit.
CAUTION
Install the air conditioner in a location with sufficient strength
to support the weight of the unit. Take reinforcement
measures when necessary.
The unit may fall and cause personal injury if the location is
not strong enough.
Carry out the specified installation works to prevent strong
winds or earthquakes.
Improper installation may cause the unit to drop leading to
accidents.
Before wiring/pipe layout, make sure that the installation area
(walls and floor) is safe and free of water, power, gas, and
other hidden dangers.
WARMING
Enough space for installation and maintenance.
The ceiling is level, and the structure is strong enough to support
the weight of IDU; take reinforcement measures when
necessary.
Airflow in/out of the machine is not obstructed, and the external
air exerts minimum impact.
Easy to supply airflow to every corner in the room.
Easy to drain fluids from the connected piping and water
discharge piping.
No direct heat radiation.
Avoid installation in narrow spaces or where there are more
stringent noise require-ments.
Enough space for installation and maintenance.
Unobstructed airflow in/out of the unit; no strong breeze.
The site should be dry and well-ventilated.
The supporting surface should be flat and able to bear the
weight of the unit. The ODU should be able to be installed
horizontally without increasing vibration and noise. Take
reinforcement measures when necessary.
The operating noise and the discharged air should not affect
neighbours.
There should be no leakage of flammable gas nearby.
It should be easy to install the connecting pipes and complete
electrical connections.
The level difference of connection pipes and the lengths of
connection pipes must be within the allowed ranges.
