Safety precautions
Carefully follow the precautions listed as below because they are essential to guarantee the safety of SAMSUNG product.
WARNING
• 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.
Warning
Carefully read the contents of this manual before installing the control kit 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 manual in a safe location and remember to hand it over to the new owner if the kit is sold or transferred.
The kit 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, and protections regularly. These operations shall be
performed by qualified personnel only.
The unit contains various electric parts, which should be kept out of the reach of children.
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 materials must be disposed of in accordance with local regulations.
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 while running the units.
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.
When service works required, make sure to disconnect the power supply at least 1 minute to prevent electric shocks.
- Always check the voltage at the terminals of main PCB before trying to touch.
Use electric wires which manual designated. Connections between wires and terminals shall be assembled without any
tension. If the assembly works is not implemented well, it can lead to have product damages and fires.
After wiring works, terminal block cover shall be fixed firmly. Without cover, it can cause to have product damage and fire.

Avoid locations where flammable elements and explosive chemicals are stored.
Choose a specific wall which can withstand the weight of unit and an external force.
Mounting the unit
Procedure Remark
1. Remove 2 bolts from the unit.
Bolt
2. Open the top cover and install 4 screws on the wall.
3. Close the top cover and install 2 bolts again into the unit.

Before fixing the rear cover, clear
30mm of space on the top and
60mm on the right side.
Fasten the screw in the
screw hole.
3. Connect the orange and brown wires from the wired remote controller to the power cable (V1, V2) of indoor unit.

4. Reassemble the wired remote controller.
When you reassemble the wired remote controller, match the grooves on the left side.
• When using an extension cable, make sure that the communication cable and the power cable is installed
separately. (If not, it may cause malfunction of the wired remote controller.)
• Power cable of the wired remote controller(V1,V2) should be connected to the one indoor unit only.

Wiring works
Selection for the power and booster heater wire terminal
Connect the cables to the terminal board using the solderless ring terminal.
Use certified and verified cables.
Connect using a driver which is able to apply the rated torque to the screws.
If the terminal is loose, fire may occur caused by arc.
If the terminal is connected too firmly, the terminal may be damaged.
External force should not be applied to the terminal block and wires.
The cable ties to fasten the wire should be an incombustible material, V0 or above.
(The cable ties should be used to fasten the power wire and they are supplied with the unit.)

Grounding work
Grounding must be done by a qualified installer for your safety.
Grounding the power cable
The standard of grounding may vary according to the rated voltage and installation place of the air conditioner.
Ground the power cable according to the following.
Installation place
Power condition
High humidity Average humidity Low humidity
Electrical potential of lower than 150V
Perform the grounding work
3.
Note 1)
Perform the grounding work 2
if possible for your safety.
Note 2)
Electrical potential of higher than
150V
Must perform the grounding work 3.
Note 1)
(In case of installing circuit breaker)
Note 1) Grounding work 3
• Grounding must be done by your installation specialist.
• Check if the grounding resistance is lower than 100Ω. When installing a circuit breaker that can cut the electric circuit in
case of a short circuit, the allowable grounding resistance can be 30~500Ω.
Note 2) Grounding at dry place
• The grounding resistance is should be lower than 100Ω. (It should not be higher than 250Ω)
Examples to use cable striper
<Cable striper>
1. Adjust the blade position by coin(the controller is at the bottom side of the tool). Fix the
blade position according to the outer sheath thickness of the power cable.
2. Fix the power cable and tool by using the hook at the top side of the tool.
3. Cut out the outer sheath of the power cable by revolving the tool in the direction of the
arrow, two or three times.
4. At this situation, cut out the outer sheath of the power cable by moving the tool toward
the arrow direction expressed.
5. Slightly bend the wire and pull out the cut part of the outer sheath.
