1. Precautions
1-1 Precautions for the Service
O Use the standard parts when replacing the electric parts.
– Confirm the model name, rated voltage, rated current of the electric parts.
O When repairing the equipment, connection of the harness parts must be firm and solid.
– A loose connection may cause noise or other malfunction.
O When assembling and disassembling the equipment while it is laid down, lay it on soft cloth.
– Otherwise it may scratch the back of the exterior of the product.
O Remove dust or dirt completely from the housing block, wiring block and service parts during repair.
– This helps prevent the danger of fire caused by tracking or short circuit.
O Fasten the valve caps of service valves and charging valves of outdoor unit as much as possible using adjustable wrenches.
O Check the status of the components’ assembly after repair service.
– The status must be the same as before the repair service.
1-2 Precautions related to static electricity and PL
OThe PCB power supply block is susceptible to static electricity. Therefore, care must be taken during repair or measuring
while the power is on.
– Wear insulation gloves for PCB repair or measuring.
OCheck whether the installation location is at least two meters away from other electronic products such as TV, video, or
audio.
– Otherwise, the video quality might be degraded or noise might be generated.
ODo not let end users repair the products themselves.
– Unauthorized disassembly might cause electric shock or fire.

Precautions
4Samsung Electronics
1-3 Precautions for the Safety
ODo not pull any electric wires and do not touch an auxiliary power switch with a wet hand.
– There is a danger of electric shock or fire.
OIn case any wire or power plug has been damaged, replace it to eliminate any possible danger.
ODo not bend the power cord by force and do not put any heavy object on the power cord.
– There is a danger of electric shock or fire.
ODo not use multi socket.
– There is a danger of electric shock or fire.
OGround the product if necessary.
– Be sure to ground the product if there is any danger of electric leakage due to water or moisture.
OBe sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts.
– There is a danger of electric shock.
OIn case the product will not be in use for a long time, the battery of remote control should be kept separately.
– Leakage of inside fluid can cause break down of remote control.
O
The installation must be done by the manufacturer or its service agent or a similar qualified person in order to avoid a hazard.
– Installation by an unqualified person may cause a water leakage, electric shock or fire and so on.
O The electric work must be done by service agent or similarly qualified persons according to national wiring regulations and use
only rated cable.
– If the capacity of the power cable is insufficient or electric work is not properly completed, electric shock or fire may occur.
O Use only rated parts and tools.
– If you don't use the rated parts and tools, it can cause trouble with the air conditioner and bring about injury.
O If any gas or impurities except R410A refrigerant come into the refrigerant pipe, serious problem may occur and it may cause
injury.
O Leak test must be done using only Nitrogen(NO 2 )gas.
O R410A refrigerant is used for EHS.
– 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. 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.

Precautions
Samsung Electronics 5
1-4 Precautions for handling a system containing refrigerants
All system containing refrigerants shall be removed under regional regulations prior to the disposal to
prevent the potential health and environmental consequences.
OHarmful for human body
– When emitted liquid refrigerant contacts human body, contacted area may get frostbite, blister or become numb.
If refrigerant leaks in airtight area, lack of oxygen may cause suffocation. When refrigerant is heated, it may generate harmful gas.
OPrecautions for handling container
– Do not apply shock or heat to the refrigerant container.
1-5 Precautions for the brazing
OClear any dangerous or inflammable materials in surrounding environment.
OMake sure to empty the remaining refrigerant in the product or pipe before brazing.
– Brazing with the refrigerant still remaining in the product or pipe may cause poor result and generate harmful gas. Furthermore,
pressure of the refrigerant may increase and cause damage to the leaking part. This may lead harmful refrigerant and oil to spurt
out which can be dangerous for service personnel.
OUse nitrogen gas to get rid of the oxide forming during brazing.
– Using other type of gas may cause damage to the product or the exterior.
1-6 Precautions for charging refrigerants
OAdd quantity of the refrigerant using a scale and perform a test operation with S-net.
– Product performance may decrease if you add excessive amount of refrigerant.
ODo not charge refrigerants while heating the container up.
– The container may get damaged by the heat and result in explosions.
ODo not operate the product without pressure switch(for product protection) and sensor.
– If there are any internal blockage, high refrigerant pressure increase may damage the product or exterior.

2. General Overview
2-1 Features of the System
POWER SAVING
EHS(Eco Heating System) considers the trend in air conditioner use. It optimizes the
energy efficiency of loads ranging from partial to full. It achieves an excellent energy
effect for the users of the air conditioner.
Samsung patented compressor
Samsung has been researching and developing compressors since the 70's.
It has developed power saving compressors for more than thirty years.
The EHS(Eco Heating System) compressor adopts a double-rotor BLDC compressor with permanent magnets made by Samsung.
Electricity for the compressor rotor is obtained from a neodium-iron-boron permanent magnetic material (boron magnet can attract iron
material weighing 1000 times its own weight.) It strengthens the rotary moment of the compressor to maximize the entire efficiency of the
compressor.
BLDC electricity
“Permanent magnet,” strong magnetic rotor
Double rotor compression cylinder
Nd-Fe-B Neodium-Iron-Boron magnet
SAMSUNG's double-rotor compressor has the upper and lower rotors designed symmetrically.
The double rotor in symmetry can remove vibrations caused by the eccentric design of the cylinder.
2 rotors balancing the rotary moment
Centered symmetry

High efficiency heat exchanger
EHS(Eco Heating System) uses new multiple-teeth screw pipes with a diameter of 8 mm to improve the heat exchangeability of the pipe by
30.8%.
The water-friendly aluminum foil in the heat exchanger uses the G-fin patent design to improve the efficiency of heat exchange by 13%.
DC fan electricity
The EHS(Eco Heating System) outdoor machine uses DC fan electricity. The rotational speed of electricity is 100 RPM to 1050 RPM with
step-free control. The electrical efficiency is improved by about 33% compared to AC electricity.

2-1-1 Key features of the EHS(SPLIT)
Q Easy installation
No need to install the refrigerant lines in the system. Users can run the system after connecting water pipes only.
Q Integrated Heating & Cooling system
Plate Heat exchanger is a integral part in heating & cooling system. For user’s convenience, PHE is integrated into the system.
This concept will help space saving and lower costs for pipe line reduction.
Q Running Costs-Reduction of Up to 33.3%
Samsung EHS, known for its world class efficiency (12kW floor heating system with COP of 4.60), can reduce 33.3% of your run-
ning costs as compared to a gas boiler.
Q High Performance at Low Temperature
Samsung EHS is made up of an inverter compressor optimally operated according to the outdoor temperature, offering heating
performance of 90% at -10°C and reliable frost protection at -20°C.
