Page 7: Safety Precautions
3.2 Safety precautions DANGER – The outdoor unit contains R290 refrigerant, an extremely flammable gas that may explode if heated. – Work on the refrigerant system must only be carried out by authorised installation personnel which has completed adequate training for the use of flammable refrigerant (EN 378, Part 4 or IEC 60335-2-40, Annex HH).
Page 8 WARNING – Inspect the refrigerant circuit for leaks before starting work, as electrostatic discharge and sparks may cause an explosion. – Ensure that there is sufficient air flow in the work area around the outdoor unit for the duration of the work.
Page 9: Emergency Procedures
CAUTION – Installation, service, repairs and disposal must comply with all applicable national and international laws and standards. – The complete installation manual must be read before installation, service or repairs to be followed. – Installation, service, and repairs must be performed by properly trained and licensed professionals that is well-acquainted with the equipment.
Page 10: Regulations To Be Observed
CAUTION Power shut down in sub-zero temperatures In cold weather, extended power outages increase the risk of water in the system freezing, potentially causing permanent damage to the indoor unit, outdoor unit, and heating system. If the system will be without power for an extended period, ensure all components exposed to sub-zero temperatures are drained of water.
Page 11 – Any tools or equipment used must be classified for use in hazardous areas (ATEX and IEC Ex certification, Zone 2). – Ensure that all possible sources of static electricity are eliminated, by earthing of equipment, devices and clothing, and by wearing anti-static work shoes (ESD safety shoes).

Page 18: Product Information
The R290 range of outdoor units has three main variants – 8 kW, 12 kW and 15 kW. The 15 kW unit is available in both single phase and three phase. The R290 range of indoor units includes an ES MCB, ES MHB and two all-in-one units (ES 100L ST and ES 250L ST) with different sizes of DHW volume.
Page 19: About The R290 Refrigerant
Figure 3: The ES R290 product range 5.1 About the R290 refrigerant The refrigerant used in this heat pump is propane (R290), a natural non-toxic hydrocarbon refrigerant with very low environmental impact and excellent thermal efficiency. This makes it an ideal choice for use in heating and cooling systems.
Page 20: Placement
WARNING Safety precautions must be followed during all times to minimize the risk of ignition in case of a propane leak. Only authorised personnel are allowed to service or remove refrigerant from the system. 5.2 Placement Follow the below instructions for the safe placement of your indoor and outdoor units. 5.2.1 Indoor unit placement The following considerations must be made regarding the placement of the indoor unit: –...
Page 21: Outdoor Unit Placement
Figure 4: Space requirement for indoor units 5.2.2 Outdoor unit placement CAUTION The heat pump may only be installed outdoors! Examples of suitable locations for the outdoor unit: – Open space – Corridor – Balcony ...
Page 22 – The heat pump must not be placed in sinks or in places where refrigerant can accumulate in the event of a leak. The heat pump must be positioned in such a way that no refrigerant enters the building in the event of a leak or can endanger people in any other way.
Page 23: Hydraulic Requirements
Figure 6: Protected area clear from windows, doors, and air inlets/outlets Figure 6 "Protected area clear from windows, doors, and air inlets/outlets", page 23 depicts the minimum boundaries from the outdoor unit to windows, doors and air inlets/outlets to prevent gas leakages into the home.
