Safety Precautions - Samsung AE044MXTPEH Mode D'emploi

Safety Precautions

• You must install the product by qualified installer. If
you install the product on your own or by unqualified
person, Samsung is not responsible for any damages
which may occur due to incorrect installation.
• Make sure to read the following safety precautions
carefully before installation.
• Make sure to observe the cautions specified in this
manual.
• Conduct a test run of the unit after installation and
then explain all system functions to the owner.
• Follow IEC (International Electrotechnical Commission)
standards for the power input and ISO (International
Standards Organization) standards for input current.
• R410A refrigerant is used for Air to Water Heat pump.
– When using R410A, moisture or foreign substances
may affect to the capacity and reliability of the
product. Safety precautions must be taken when
installing the refrigerant pipe.
– The design pressure of the unit is 4.1 MPa
(41.8 kgf/cm²). Select appropriate material and
thickness according to the regulations.
– R410A is a quasi-azeotrope of two refrigerants.
Make sure to charge liquid one when adding
refrigerant. If you charge gaseous refrigerant,
it may affect the capacity and reliability of the
product as a result of change formation of the
refrigerant.
• Connect only the indoor units fit on R410A refrigerant.
Check whether the indoor units can be connected with
the product's catalogue. (When incorrect indoor units
are connected, they cannot operate normally.)
• When installing, use tools and materials for R410A
only. If you use tools and materials for R22, there is
potential risk of bursting, injury, electric shock and
fire because the pressure of R410A is higher than the
pressure of R22(conventional).
WARNING
• Hazards or unsafe practices that may result in
severe personal injury or death.
• Installation must be carried out by a qualified installer.
Do not attempt to repair, move, modify or reinstall the
unit on your own since such act may cause fire, electric
shock or water leakage.
• Install the unit in a place where it is strong enough
to hold the product weight. When installed in place
where it is not strong enough to withhold the product
weight, the unit could fall and cause injury.
• The unit should be installed in accordance with the
National Electrical regulations. Check if the voltage
and the frequency of the main power supply are
those required for the unit to be installed and check
the connection. Do not share the power outlet with
other appliances. Incomplete connection, defective
insulation or exceeding the permissible current may
cause electric shock or fire.
• Use the specified wires to connect the indoor and
outdoor units securely and attach the wires firmly to
the terminal block connecting sections so that the
pressure is not applied to the sections. Inappropriate
connection and fixing could cause fire.
• Attach the electrical cover to the indoor and outdoor
unit securely without any gaps. If there are any gaps,
there is potential risk of fire or electric shock due to
dust or water.
• Make sure to use the part provided or specified parts
for the installation work. The use of defective parts
could cause an injury or leakage of water due to a fire,
an electric shock, the unit falling, etc.
• Make sure that the refrigerant gas does not leak after
completing the installation. If the refrigerant gas of
the indoor unit leaks and comes into contact with the
fan heater, space heater or stove, harmful gas will be
generated.
• Ensure that the national safety code requirements
have been followed for the main supply circuit. Ensure
that a proper ground wire is in place. Do not connect
the ground to a gas pipe, water pipe, lightning rod or
telephone grounding. Defective grounding could cause
electric shock.
