Safety Precautions
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 4.1MPa (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).
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.
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.
