OUse the standard parts when replacing the electric parts.
– Confirm the model name, rated voltage, rated current of the electric parts.
ORepair the disconnection of HARNESS securely when repairing the break down.
– If there is any connection error, it causes an abnormal noise and incorrect operation.
OIn case that you assemble or disassemble the products with laying it on the side, do work on the work cloth.
– If not, the exterior of products can be scratched.
ORemove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the
break down.
– It protects the danger of fire such as tracking and short.
OTighten tightly the service valve of outdoor unit and the cap of charging valve with a monkey spanner.
OCheck the assembly status of parts after repairing the break down.
– It should be same as the status before repairing.
1-2 Precautions for the Static Electricity and PL
OAs the PCB power terminal has a weakness for the static electricity, pay attention to it during the repair and measurement.
– Work with insulation gloves during the repair and measurement of PCB.
OCheck the distance between the product and the other electronic appliances such as TV, video, and audio.
It should be over 6.6ft.
– If not, it causes a bad picture quality or a noise.
ORepairing the products by consumer should be strictly prohibited.
– There is a danger of electric shock or fire due to incorrect disassembly.
Samsung Electronics1-1
1-3 Precautions for the Safety
ODo 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.
OIn case any wire or power plug has been damaged, replace it to eliminate any possible danger.
ODo 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.
ODo not use multi socket.
– There is a danger of electric shock or fire.
OGround the product if necessary.
– Be sure to ground the product if there is any danger of electric leakage due to water or moisture.
OBe 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.
OIn 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.
The installation must be done by the manufacturer or its service agent or a similar qualified person in order to avoid a hazard.
O
– 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(NO2)gas.
O
R410A refrigerant is used for DVM PLUS ,,,, SUPER FJM air conditioner.
– 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.
O
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.)
1-4 Others
OWhen installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the
connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe
inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.
DVM PLUS III is a module multi-system air conditioner that has the world’s largest capacity(7.5~37.5HP) with the application of a
DVI (Digital Vapor Injection) compressor, and can connect up to a maximum of 49 indoor units.
• The highest COP levels in the industry
• The smallest installation space requirement in the world
• The highest heating capacity and COP in low temperature condition (14°F/-10°C)
• Possible to connect up to 49 indoor units
• Digital unit module

New technology of DVM PLUS III
Q Digital hybrid system
DHS (Digital Hybrid System) is a brand new concept system
composed of DVI (Digital Vapor Injection) compressor, vapor
injection technology and turbo intercooler. These 3 factors
together provide highly efficient performance.
1) DVI compressor
Efficient and reliable DVI (Digital Vapor Injection) compressor
coupled with vapor injection technology has been applied to
improve cooling and heating performance and energy efficiency.

2) Vapor injection technology
Improved cooling and heating performance and COP by a new technology of two stage compression. As injecting optimized
mid-range pressure refrigerant, this technology achieved the high heating performance and COP under the lowest temperature,
which leads the industry.
• Increase refrigerant flow rates with a new vapor injection technology.
• Improved sub-cooling necessary for long piping installation while increasing cooling and heating performance and COP.

Overview
POWER SAVING
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 SUPER FJM 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.
SUPER FJM is an all-in-one type product integrating the control R&D and Samsung patented compressor.
The air conditioning system uses the latest single tube in parallel connection and both the indoor and
outdoor machines use independent electronic expansion valves to control the amount of coolant.
You can connect a maximum of nine indoor machines to one outdoor machine.
SUPER FJM 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.

4-1-2-3 Setting an indoor unit installation option(suitable for the condition of each installation location)
1. Check whether power is supplied or not.
- When the indoor unit is not plugged in, there should be additional power supply in the
indoor unit.
2. The panel(display ) should be connected to an indoor unit to receive option.
3. Set the installation option according to the installation condition of an air conditioner.
- The default setting of an indoor unit installation option is “02000-100000-200000-300000”.
- Individual control of a remote controller(SEG20) is the function that controls an indoor unit
individually when there is more than one indoor unit.
