Page 14: Important Pre-Installation Information
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. - Page 15 2m is recommended. ANY type of obstruction in front of the heat pump, even small shrubs, can block the air flow and cause cold air recirculation.

Page 18: Temperature Control Devices
3.1.1 Temperature Control Devices • The controller/user interface that is supplied with the Dimplex A-Class heat pump is used as a heat pump controller as well as a space heating and domestic hot water (DHW) controller. The preferred option is to use the user interface as a room temperature control device. -
Page 19: Space Heating Zones
3.1.3 Location of Wiring Centre If a Dimplex A-Class cylinder is used, the wiring centre is built in to the A-class cylinder and pre-wired. If a non A-Class cylinder is used, the wiring centre module must be installed. -
Page 20: Installation
Dimplex recommend the use of a power flush and purge cart to facilitate this process. - Page 21 The isolation valve on the return is also fitted with a non-return valve and a strainer (included in the Dimplex heat pump hydraulics pack). This means that in order to clean the strainer, the system does not have to be drained. Instead, it is possible just to close the isolation valves on the return and remove the strainer.

Page 23: Buffer Tank
The heat pump uses a reverse cycle defrost in order to defrost the evaporator by taking heat from the heating system. It is therefore necessary to connect a buffer tank in series with the heat pump, as shown in the hydraulic schematic diagrams (Appendices). The Dimplex A-Class cylinder range come with an integrated buffer tank, which;... -

Page 25: Electrical Information
4.2 Electrical Information The heat pump system consists of the heat pump, wiring centre and user interface. If a Dimplex A-Class cylinder is also used, the wiring centre is built into the cylinder. The user interface acts as a thermostat and is sufficient if one heating zone is present. Optional, additional temperature probes or room thermostats are required for additional heating zones. -
