Safety precautions
Warning
Carefully read the content of this manual before installing the air to water heat pump and store the manual in a safe place in order
to be able to use it as reference after installation.
For maximum safety, installers should always carefully read the following warnings.
Store the operation and installation manual in a safe location and remember to hand it over to the new owner if the air conditioner
is sold or transferred.
Store the user and installation manual in a safe location and remember to hand it over to the new owner if the air to water heat
pump is sold or transferred.
This manual explains how to install Air-Water Heat Pump. The use of other types of units with different control systems may
damage the units and invalidate the warranty. The manufacturer shall not be responsible for damages arising from the use of non
compliant units.
The air conditioner is compliant with the requirements of the Low Voltage Directive (72/23/EEC), the EMC Directive (89/336/EEC)
and the Directive on pressurized equipment (97/23/EEC).
The manufacturer shall not be responsible for damage originating from unauthorized changes or the improper connection of
electric and hydraulic lines. Failure to comply with these instructions or to comply with the requirements set forth in the “Operating
limits” table, included in the manual, shall immediately invalidate the warranty.
Do not use the units if you see some damages on the units and recognize something bad such as loud noisy, smell of burning.
In order to prevent electric shocks, fires or injuries, always stop the unit, disable the protection switch and contact SAMSUNG’s
technical support if the unit produces smoke, if the power cable is hot or damaged or if the unit is very noisy.
Always remember to inspect the unit, electric connections, refrigerant tubes and protections regularly. These operations shall be
performed by qualified personnel only.
The unit contains moving parts and electrical parts, which should always be kept out of the reach of children.
Carefully follow the precautions listed below because they are essential to guarantee the safety of the equipment.
• Always disconnect a power supply of Air-Water Heat Pump before servicing it or accessing
components inside the unit.
• Verify that installation and testing operations shall be performed by qualified personnel.
• To prevent serious damage on the system and injuries to users, precautions and other notices
shall be observed.

Do not attempt to repair, move, alter or reinstall the unit by unauthorized personnel, these operations may cause
product damage, electric shocks and fires.
Do not place containers with liquids or other objects on the unit.
All the materials used for the manufacture and packaging of the air to water heat pump are recyclable.
The packing material and exhaust batteries of the remote controller(optional) must be disposed of in accordance with local
regulations.
The air to water heat pump containing a refrigerant must be disposed in authorized center or returned to retailer as special wastes.
Wear protective gloves to unpack, move, install, and service the unit to avoid your hands being injured by the edge of the parts.
Do not touch the internal parts (water pipes, refrigerant pipes, heat exchangers, etc) while running the units.
And if you need to adjust and touch the units, have enough time for the unit can be cooled and be sure to wear protective
gloves.
In case of refrigerant leakage, try to avoid getting in contact with the refrigerant because this could result in severe wounds.
When you install the Air to water heat pump in a small room, you must consider a proper ventilation to prevent a leakage level
within the maximum permissible limit.
- In that case, you may die from suffocation by some possibility.
Make sure to safely dispose of packing materials. Packing materials, such as nails and other metal or wooden pallets may cause
children get injured.
Inspect the product shipped and check if damaged during transport. If the product has some damages,
DO NOT INSTALL and immediately discuss about the damages with the carrier or retailer (if the installer or the authorized
technician has collected the material from the retailer.)
Our units shall be installed in compliance with the spaces described in the installation manual, to ensure accessibility from both
sides and allow repairs or maintenance operations to be carried out.
If the units installed without complying with procedures described in manual, additional expenses can be asked because special
harnesses, ladders, scaffolding or any other elevation system for repair service will NOT be considered part of the warranty and will
be charged to the end customer.
Always make sure that the power supply is compliant with local safety standards.
Verify that the voltage and frequency of the power supply comply with the specifications and input power is sufficient to ensure
the operation of any other domestic appliance connected to the same electric lines.
Always verify that the cut-off and protection switches are suitably selected.
Always verify that electric connections (cable entry, section of leads, protections…) are compliant with the electric specifications
and with the instructions provided in the wiring scheme. Always verify that all connections comply with the standards applicable
to the installation of air to water heat pumps.
Devices disconnected from the power supply should be completely disconnected in the condition of overvoltage category.
Do not connect the earth wire to the gas pipe or water pipe, lighting rod, surge absorber, or telephone earth wire.
If earthing is not complete, it may cause an electric shock or fire.
Be sure to install both an earth leakage detector and circuit breaker with specified capacity in accordance with relevant local
and national regulations.
- If it is not installed properly, it may cause electric shocks and fire.
Make sure that the condensed water runs well out of the unit at low ambient temperature. Drain pipe and cond heater can frost/
ice can not grow. If drain work is not effective for releasing condensed water, it can make the units get damaged by massive ice and
system can be stop , covered by ice.
Install the power cable and communication cable of the indoor and outdoor unit at least 1m away from the electric appliance.
Protect the unit from rats or small animals. If an animal makes a contact with the electric parts, it can cause malfunctions,
smoke or fire. Please instruct the customer to keep the area around the unit clean.

•
The application examples given below are for illustration purposes only.
•
When the SAMSUNG Air-to-Water Heat Pump system is used in series with another heat source (e.g. gas boiler),
ensure that the return water temperature not exceed 55°C.
•
The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive
corrosion of the water piping.
•
SAMSUNG can not be put responsible for incorrect or unsafe situations in the water system. Make sure that the
boiler, radiators, convectors, solar collectors, UFHs, FCUs, additional pumps, pipings, and controls in the water
system are in accordance with relevant local laws and regulations under the installer's responsibility.
•
By-pass valve shall be installed for space heating loops. When one of loops or all loops are closed , water flow rate
could be low condition. To keep flow rate approximately and prevent flow stop, the by-pass valve shall be installed
between supply collector and return collector.
•
SAMSUNG shall not be held liable for any damage resulting from not observing this rule.
