Electrical Information; Access To Electrical Connections - Opening The Heat Pump - Dimplex A8M Installation Manual

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.
The wiring diagrams in the Appendices section show the different possible wiring configurations for
systems with and without a Dimplex A-Class cylinder.
WARNING: Before opening the heat pump, ensure all circuits are isolated.
WARNING: Ensure that the components in the electrical box do not get wet when the electrical box is
opened.
WARNING: The main 230V power cable must be supplied via a suitable sized exterior isolator, lockable
in the OFF position.
