4 PREPARATIONS BEFORE
INSTALLATION
4.1 Overview
This chapter mainly describes the precautions and
things to note before the unit is installed at the site.
This mainly includes the following information:
Choosing and Preparing the Installation Site.
Selecting and Preparing the Refrigerant Piping.
Selecting and Preparing the Electrical Wiring.
4.2 Choosing and Preparing
the Installation Site
4.2.1 Site requirements for installation of
the outdoor unit
Provide sufficient space around the unit for
maintenance and air circulation.
Make sure the installation site can bear the weight
and vibrations of the unit.
Make sure the area is well ventilated.
Make sure the unit is stable and level.
Choose a place where the rain can be avoided as
much as possible.
The unit should be installed in a location where the
noise generated by the unit will not create an
inconvenience to people.
Choose a site that will comply with the applicable
laws.
Do not install the unit in the following locations:
An environment where there is a potential risk of
explosions.
Where there is equipment emitting electromagnetic
waves. Electromagnetic waves may disrupt the
control system, and cause the unit to malfunction.
Where there are existing fire hazards like leakage of
flammable gases, carbon fibers, and combustible
dust (such as diluents or gasoline).
Where corrosive gases (such as sulphurous gases)
are produced. Corrosion of copper pipes or welded
parts may lead to refrigerant leakage.
Where mineral oil mist, spray, or steam may exist in
the atmosphere. Plastic parts may age, fall off or
cause water leakage.
Where there is a high salt content in the air such as
places near the sea.
CAUTION
Electric appliances that should not be used
by the general public must be installed in a
safe location to prevent others from getting
close to these electric appliances.
Both indoor and outdoor units are suitable for
the installation of commercial and light
industrial environment.

interference. However, there is no guarantee
that there will be no interference during a
specific installation process.
Therefore, it is suggested that you install the
units and wires at an appropriate distance
from devices like sound equipment and
personal computers.
Do take into considerations adverse environmental
conditions such as strong winds, typhoons or
earthquakes as improper installation may cause the
unit to overturn.
Take precautions to make sure water will not
damage the installation space and environment in
the event of a water leakage.
If the unit is installed in a small room, refer to section
4.2.3 "Safety measures to prevent refrigerant leak" to
make sure the refrigerant concentration does not
exceed the permissible safety limit when there is a
refrigerant leak.
Make sure the air inlet of the unit is not facing the
predominant wind direction. Incoming wind will
disrupt the operations of the unit. If necessary, use a
deflector as an air baffle.
Add water discharge piping on the base so that the
condensed water will not damage the unit, and
prevent the pooling of water when work is in
progress.
4.2.2 Site requirements for installation of
outdoor unit in cold regions
NOTE
Snow protection equipment must be installed
in areas with snowfall. Refer to the following
figure, (malfunctions are more common when
there
are
insufficient
facilities). In order to protect the unit from
accumulated snow, increase the height of the
rack, and install a snow shield at the air inlets
and outlets.
Do not obstruct the air flow of the unit when
you install the snow shield.
