WARNING: Before removing the cover of the heat pump, cylinder or wiring centre, ensure that all
electrical circuits are isolated.
NOTE: The heat pump has a multi-layered, software generated alarm management system, which
prevents it from running outside its operating limits.
NOTE: If an alarm / message occurs, the heat pump will attempt to take remedial action before causing
the system to stop completely if the problem persists. However, the overriding safety feature is the high
pressure switch, which de-energises the main contactor supplying power, in accordance with EN378.
NOTE: This device is suitable for mains connection only (230V, 1P&N, 50Hz) and is not suitable for
operation with an electrical generator or power modulator, due to possible effects on the quality of the
electrical supply. Any attempt to do so will void warranty.
• Means for disconnection from the supply mains must be incorporated into the xed wiring in
accordance with the national wiring regulations.
• This device must be installed in accordance with national wiring regulations.
• The local wiring regulations should always be followed paying particular attention to the mixing of
low voltage and extra low voltage cabling.
• Ensure the incoming power supply and the distribution board are suitably rated.
• Ensure that the regulations specied by the local electricity supplier have been adhered to.
• All fuse rating and protective overload device information is provided in the wiring label located
on the inside of the front bottom panel of the heat pump. For instruction on how to remove this
panel please see section 3.1.
• The installation of a heat pump designated residual current device (type B RCD) having a rated
residual operating current not exceeding 30mA is recommended, in accordance with local
regulations (BS7671 for UK installations).
• The correct earthing (grounding) of the heat pump is of the utmost importance.
CAUTION: The heat pump has a high leakage current and must be properly grounded for safety in
accordance with local and national regulations regarding equipment with a leakage current exceeding
3.5ma.
CAUTION: Two separate, designated RCD devices should be tted - one for the heat pump and one for
the cylinder. The heat pump system must not share an already existing domestic RCD device.
