1.2.6 I NTENDED U SE
This product is designed to extract heat from outside air to provide energy for a water-based heating system, and is
intended for domestic and light commercial use. Any other use beyond that intended by the manufacturer is prohibited.
This requires the user to abide by the manufacturer’s product information. Please refrain from tampering with or altering
the device.
1.2.7 L EGAL
The construction and design of the heat pump complies with all relevant EU directives (see CE declaration of
conformity in appendix section).
When connecting the heat pump to the power supply, the relevant EN and IEC standards must be adhered to. Any
further connection requirements stipulated by the network operation must also be observed.
When connecting to the heating system all applicable regulations must also be adhered to.
1.2.8 C ONNECTION TO THE G RID - N OTIFYING THE DNO (D ISTRIBUTION N ETWORK O PERATOR )
Before you connect a heat pump to the grid, the necessary permissions must be granted by the distribution network
operator. Not obtaining the necessary permissions may result in an unexpected network upgrade charge, and may
compromise the integrity of the local supply if a ‘disturbing load’ is connected to the network.
The required forms are supplied by Dimplex and must be filled in by the heat pump installer alongside the client. We
recommend notifying the DNO as early as possible in the planning stage to discuss the project and any additional
information. Further information can be found on the Energy Networks website (www.energynetworks.org) or from your
local DNO.
1.2.9 H EAT P UMP S IZING
• Ensure that the correct size heat pump has been selected in accordance with the latest version of MIS3005 (for UK
installations).
• If a non A-Class heat pump cylinder is being used, ensure that it has been accurately sized with the appropriate coil
surface area of the cylinder to match the heat pump’s output and flow rate requirements, and that all necessary
hydraulic connections have been considered in connecting it to the heat pump system.
• Ensure that suitable heat emitters have been sized in accordance with the Heat Emitter Guide (for UK installation)
and selected ensuring a low flow temperature design. To maximise system efficiency it is important to design the
system with the lowest flow temperature possible.
