Precautions when connecting the
electrical wiring
WARNING
• Make sure first the water piping is connected before the
electrical wiring work.
• When removing or relocating the equipment, power off
first and then disconnect the electrical wiring.
• Connect the air to water heat pump to a protected earth
(PE) before connecting the phase and neutral to the
product.
• Follow the local installation standards and regulations
when installing electrical wiring.
Electrical wiring should be installed by a certified
electrician or certified installer. Failing to comply, might
lead to damaging the product, starting a fire and personal
injury, electrocution or death.
• Make sure that wiring work must be done by an authorized
electrician.
The wiring materials and wiring work must comply with the
applicable legislation.
• Always verify that a suitable grounding connection is available.
• Verify that the voltage and frequency of the power supply
comply with the specifications and that the installed power
is sufficient to ensure the operation of any other domestic
appliance connected to the same electric lines.
• Always verify that the cut-off and protection switches are
suitably dimensioned.
• Verify that the air to water heat pump is connected to the
power supply in accordance with the instructions provided in
the wiring diagram included in the manual.
• Always verify that electric connections (cable entry, the section
of leads, protections…) comply with the electric specifications,
local regulations and installation standards and with the
instructions provided in the wiring scheme.
Always verify that all connections comply with the standards
applicable to the installation of air to water heat pumps.
• Depending on the condition of power supply, unstable power or
voltage may cause malfunction of the parts or control system.
(Avoid using power supply from an electric generator, like on
a ship etc).
CAUTION
• Make sure that you earth the cables.
– Do not connect the earth wire to the gas pipe, water
pipe, lighting rod or telephone wire. If earthing is not
complete, electric shock or fire may occur.
• Install the circuit breaker.
– Failing to install a circuit breaking device may result in
electric shock and fire occurrence.
• Install the power cable and communication cable of the
indoor and outdoor unit according to IEC 60364-1 (Electrical
installations and protection against electric shock).
• Be sure to install both an earth leakage detector and circuit
breaker with specified capacity in accordance with relevant
local and national regulations.
– If it is not installed properly, it may cause electric
shocks and fire.

This equipment complies with IEC 61000-3-12 provided
that the short-circuit power (SSC) is greater than or equal
to 3.3[MVA] at the interface point between the user’s
supply and the public system. It is the responsibility of
the installer to ensure, by consultation with the energy
company if necessary, that the equipment is connected
only to a supply with a short-circuit power (SSC) greater
than or equal to 3.3[MVA].
