Installation manual

3.1.2 General
 Installation and any service work on the heat
pump may only be performed by authorised and
qualified installer and after-sales service
technicians.
 Additional heating may be required if the heat
pump is intended to dry out a new or renovated
building, as the initial heat load may be higher
than the calculated load.
 Products not installed with the Dimplex hydraulics
packs will not be supported by Dimplex. This
includes but is not limited to thermal stores.
3.1.3 Safety
 The heat pump contains refrigerant at high
pressure. Safety measures are in place to avoid
system pressure build up.
 Stage 1: Pressure transducer stops compressor.
 Stage 2: Pressure switch switches heat pump off.
All safety devices reset automatically.
 The heat pump has a multi-layered, software
generated alarm management system. However,
the overriding safety feature is the high pressure
switch, which de-energises the main contactor
supplying power, in accordance with EN378.
 This appliance can be used by children aged 8
years and above and by persons with reduced
physical, sensory or mental capabilities or lack of
experience/knowledge, provided that they have
been given supervision or instruction concerning
the use of the appliance in a safe way and
understand the hazards involved.
 Children must not play with the appliance.
Cleaning and user maintenance must not be
carried out by children without supervision.
3.1.4 Maintenance
 If the heat pump may be disconnected from the
power supply for prolonged periods of time, or
where power supplies are susceptible to failure,
antifreeze must be added to the system.
 Never use cleaning agents containing sand, soda,
acid or chloride as these can damage surfaces/
components.
 We recommend the installation of a suitable
filtration protection system and the use of a
corrosion additive for the heating system to
prevent the formation of deposits (e.g. oxide and
solids) in the condenser of the heat pump. The
return isolation valve provided in the hydraulics
pack has a built in strainer to help prevent debris
entering the condenser and must be fitted.
NOTE: During the commissioning of the domestic hot
water cylinder, ensure that the cylinder is full and no
water is drawn from the cylinder as this will adversely
affect the heat pumps operation.
3.1.5 Electrical Warnings
 Before removing the cover of the heat pump,
cylinder or wiring centre, ensure that all electrical
circuits are isolated.
 Means for disconnection from the supply mains
must be incorporated into the fixed wiring in
accordance with the national wiring regulations.
 This device must be installed in accordance with
national wiring regulations.
 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.
 The installation of a separate residual current
device (RCD) having a rated residual operating
current not exceeding 30mA is recommended.
 The local wiring regulations should always be
followed paying particular attention to the mixing
of low voltage and extra low voltage cabling.
NOTE: The digital inputs are volt free. If any voltage
(such as a switch live 230V) is connected, irreparable
damage will be caused to the wiring centre.
3.2 Intended Use
This device is only intended for domestic 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.
3.3 Legal
The construction and design of the heat pump
complies with all relevant EU directives (see CE
declaration of conformity).
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.
