Installing the unit
WARNING
IMPORTANT: When installing the unit, always remember
to connect first the refrigerant tubes, then the electrical
lines.
• Upon receipt, inspect the product to verify that
it has not been damaged during transport. If the
product appears damaged, DO NOT INSTALL it and
immediately report the damage to the carrier or
retailer (if the installer or the authorized technician has
collected the material from the retailer.)
• After completing the installation, always carry out a
functional test and provide the instructions on how to
operate the air conditioner to the user.
• Do not use the air conditioner in environments with
hazardous substances or close to equipment that
release free flames to avoid the occurrence of fires,
explosions or injuries.
• Our units should be installed in compliance with the
spaces shown in the installation manual, to ensure
accessibility from both sides and allow repairs or
maintenance operations to be carried out. The
unit's components should be accessible and easy to
disassemble without endangering people and objects.
• For this reason, when provisions of the installation
manual are not complied with, the cost required to
access and repair the units (in SAFETY CONDITIONS,
as set out in prevailing regulations) with harnesses,
ladders, scaffolding or any other elevation system will
NOT be considered part of the warranty and will be
charged to the end customer.
• While in installation or relocation of the product, do
not mix the refrigerant with other gases including air
or unspecified refrigerant. Failure to do so may cause
pressure increase to result in rupture or injury.
• Do not cut or burn the refrigerant container or pipings.
• Use clean parts such as manifold gauge, vacuum
pump, and charging hose for the refrigerant.
• Installation must be carried out by qualified personnel
for handling the refrigerant. Additionally, reference the
regulations and laws.
• Be careful not to let foreign substances (lubricating
oil, refrigerant other than R32, water, etc.) enter the
pipings.
• When mechanical ventilation is required, ventilation
openings shall be kept clear of obstruction.
• For disposal of the product, follow the local laws and
regulations.
• Do not work in a confined place.
• The work area shall be blocked.
• The refrigerant pipings shall be installed in the
position where there are no substances that may
result in corrosion.
• The following checks shall be performed for
installation:
‐ The ventilation devices and outlets are operating
normally and are not obstructed.
‐ Markings and signs on the equipment shall be
visible and legible.
• Upon leakage of the refrigerant, ventilate the room.
When the leaked refrigerant is exposed to flame, it
may cause generation of toxic gases.
• Make sure that the work area is safe from flammable
substances.
• To purge air in the refrigerant, be sure to use a vacuum
pump.
• Note that the refrigerant has no odour.
• The units are not explosion proof so they must be
installed with no risk of explosion.
• This product contains fluorinated gases that
contribute to global greenhouse effect. Accordingly, do
not vent gases into the atmosphere.
• For installation with handling the refrigerant(R-32),
use dedicated tools and piping materials.
• Servicing and installation shall be performed as
recommended by the manufacturer. In case other
skilled persons are joined for servicing, it shall be
carried out under supervision of the person who is
competent in handling flammable refrigerants.
• For servicing the units containing flammable
refrigerants, safety checks are required to minimise
the risk of ignition.
• Servicing shall be performed following the controlled
procedure to minimize the risk of flammable
refrigerant or gases.
• Do not install where there is a risk of combustible gas
leakage.
• Do not place heat sources.
