Key information about the EHS Mono R290

The Samsung EHS Mono R290 is an exceptional heating system, known for its future-conscious design. This heat pump utilises R290, a type of propane refrigerant, which is less harmful to the climate, making it a more responsible choice.

The R290 refrigerant offers excellent thermodynamic properties, enhancing the system’s performance.

The EHS Mono R290 is a monobloc heat pump, which means that the heat pump houses all the essential components in the outdoor unit. All the refrigerant pipes are factory assembled and factory sealed. Unlike a split heat pump, it doesn’t need to work on the refrigerant side.

Samsung Climate Solutions offer two different types of monobloc heat pumps: one with the pump, expansion and control components built into the outside unit which simplifies installation and requires less indoor space within the home. It’s particularly well-suited for residential and light commercial applications, providing space, heating and hot water production. The second type is the standard EHS Mono R290 heat pump with the pump, expansion and controls components fitted separately inside the house.

Thanks to its inverter technology, the EHS Mono R290 can modulate its output to match the heating demand, resulting in energy reduction and consistent comfort. Additionally, the unit is compatible with smart control systems, allowing users to manage their heating remotely, further optimising energy consumption.

Important information related to refrigerants

Installers need to understand the significance of refrigerants, refrigerating systems and heat pumps. This is crucial for ensuring safety, environmental responsibility and efficiency. Guidance from key industry standards is essential. These standards include, EN378, IEC 60335, ISO 5149,
ISO 22712 and ISO 817.

EHS Mono R290 General precautions

Installation, inspection and maintenance

Safety protocols

Installation, inspection and maintenance of EHS Mono R290 require strict adherence to safety protocols to mitigate the potential hazards associated with flammable refrigerants like R290. These precautions are critical and align with safety guidelines and industry standards.

Safety considerations revolve around three fundamental preconditions that must not occur simultaneously:
refrigerant release, the presence of a flammable mixture of R290 and air, and an active ignition source. To prevent these occurrences, installers must follow specific safety measures.

Before working in temporary flammable zones, precautions include ensuring proper ventilation, not using a mobile phone, using non-sparking gas detectors, instructing staff, displaying no-smoking signs, and having appropriate tools and equipment.

Recommended checks ahead of installation and maintenance

Follow below recommended checks ahead of installation and maintenance.

Familiar with the information provided by other sources, such as the system equipment manufacturers, component manufacturers, refrigerant suppliers, and Material Safety Datasheets (MSDSs). Occupants should be aware of manufacturer operating instructions, procedures, guidelines and safety issues regarding the equipment. Be made aware of evacuating the space following the accidental release of a flammable refrigerant.
2| Safety distance
Safety distance to building openings with regard to the movement of refrigerant required. For outdoor installations refrigerating system sited in the open air shall be positioned to avoid leaked refrigerant following into a building or otherwise endangering people and property.
3| No ignition Sources
No smoking, including displaying ‘No Smoking’ signs. Survey the area around the equipment before servicing to establish any flammability or ignition risks. Remove all sources of ignition. Be aware that a cell phone or similar
electronic devices could be the source of ignition.
4| Labels
R290 is classified as a highly flammable category A3 gas and must be labeled accordingly.
5| General Work Area
Instruct anyone in the temporary flammable zones as to the nature of the work.
6| Personal Protective Equipment
Technicians should wear appropriate protective equipment, including chemical goggles, protective gloves, grounding probes, and anti-static bands.
7| Free Air Movement
Ensure that free air movement around all refrigerant-containing parts of the systems can be achieved. Depending
on the size of the room, especially in a confined space, mechanical ventilation may need to be considered. The
ventilation should displace any released refrigerant and preferably expel it externally
8| Base Emptiness
R290 is heavier than air. Precautions should be made against refrigerant collecting in troughs and low points
of the structure.
9| Electrical Devices
An initial safety check of components to see if a fault exists that could compromise safety. Capacitors should be
discharged with bleed resistors (minimum 2 Watt/10,000) or multimeter’s. Do not work on ‘live’ electrical components.
Maintain and enforce proper usage of ground equipment to prevent accidents and ensure safety
10| Certified Equipment

• Gas Leak Detectors and Monitors, Electrical Test meters, Portable Lighting, non-sparking tool, and etc.

11| Work Space Guidelines

• Good ventilation
• Dry powder fire extinguishers

Refrigerant removal and recovery procedure

Refrigerant removal and recovery involve the careful extraction of refrigerant gases from cooling systems and air conditioners, using specialised equipment to ensure these gases are safely contained and recycled.
Preventing environmental harm and complying with regulatory standards.

Always use a refrigerant explicitly labelled as ‘R290’ and avoid using Propane alone.

Owing to the minimal amount of the R290 charge, precise weighing of the R290 introduced into the system is imperative to guarantee optimal performance.

Prior to commencing work on electrical components, the corresponding power supply must be disconnected before opening any sealed parts.

These comprehensive procedures ensure the safe and efficient installation, inspection, and maintenance of R290 systems.

Building safety, fire department, outdoor safety

• Flammable

• Poisonous

• Danger

• Electricity

• No smoking

Building safety, outdoor safety, and the involvement of the fire department are crucial when working with refrigeration systems.
Safety distances are essential to prevent refrigerant leaks from endangering people and property

• The Safety Zone shall not have any building openings such as: Windows, Doors, Light wells, Flat roof windows, Air inlet/Outlet of ventilation systems, etc
• R290 refrigerant is heavier than air and can be collected on the ground. There should be no sinking or deepening of the ground in the safety zone
• The safety zone should not extend to intact buildings or public spaces
• The safety zone cannot be modified later to violate the protection rules

EHS Mono R290 safety zone measurements

• When installed on the ground when installed in a place with a flat roof
  

• When installed on the ground on the front of the building wall
  

• When installed at the right corner of a building
  

• When installed at the left corner of a building
  

• Wall on suction side
  

• When the air outlet is towards the wall
  

The designated safety zone must be free from any structural openings such as windows, doors, light wells, skylights, and air inlets or outlets of ventilation systems. R290 refrigerant, being denser than air, tends to sink and accumulate at ground level. Therefore, there must be no depressions or excavations within the safety zone. Furthermore, this zone should not encroach upon intact buildings or public areas. Once established, the safety zone must not be altered in any way that contravenes established safety regulations.

Refrigerating equipment in the open air must be positioned to prevent refrigerant from flowing into building openings or ventilation systems.
Sheltered equipment should have natural or forced ventilation to maintain safety.
The work area should be adequately ventilated before working on the refrigerant circuit, brazing, or dealing with electrical components.

Protection gear and certification needed

When working with EHS Mono R290 systems, protection equipment and certification (if needed) are of paramount importance. The requirements for protective gear and equipment and in line with those for existing R32 products. Installers should wear appropriate protective equipment, including chemical goggles, protective gloves, grounding probes, and anti-static bands to minimise risks associated with flammable refrigerants.

Product scrapping and recycling

Product scrapping and recycling at the end of a system’s life is a crucial phase that applies to refrigeration systems irrespective of the refrigerant used. Standard procedures include:

• Removal of refrigerant
• Removal of oil
• Dismantling the refrigeration system and related equipment
• Transporting refrigerant, oil, and hardware to designated collection stations
• Transporting system construction materials (metals, plastics, etc.) to appropriate recycling centres

These actions ensure responsible and environmentally-friendly disposal of refrigeration systems.
