Electrical connection
IMPORTANT: The electric connection of the heat pump can only be
performed by an authorized electrician in accordance with local electrical
standards and requirements.
WARNING: The device operates at dangerous electrical current and
voltage.
DANGER: Danger of electric shock!
a)
The heat pump must be connected through a single circuit-breaker specified
in section 3.1
Technical data for a particular model. The dimensioning of the power supply must be sufficient
(the suggested cross section of the conductors is 3 x 2,5 mm
2
). It is important to make sure and it
is nonconditionned requirement of the manufacturer to install the heat pump together with RCD
(Residual Circuit Breaker) with the actuating current up to 30mA. The power supply
characteristics (voltage, phase and frequency) must be in complete compliance with the operating
parameters of the device (please refer
to section 3.1 Technical data).
b)
The electric connection must be performed by an authorized electrician and must be in accordance
with the valid local electro-technical requirements.
c)
The electric installation of the heat pump must be grounded appropriately. The grounding
distributor´s impedance must be in compliance with local valid electro-technical requirements.
d)
The electro connection of the heat pump must be simple, clear and comprehensible. It is highly
advised to have the connection performed in a way that would allow a third party electrician to
understand the connection at no time. Unnecessary cross connections are not appropriate.
e)
It is important to carefully check and measure the electric installation before putting it into live
operation.
f)
The suggested protection is stated in the chart below:

In order to protect the unit from weather anomalies it is recommended to install power surge
protection class 1. B+C+D.
Note: Should above points a) to h) be in contrary with local electrical standards or requirements,
please contact your distributor or reseller.

Multiple heat pump connection
Sometimes it is necessary to install multiple heat pumps into a single swimming pool in order achieve
requested water temperature. Such installation is particularly advised on public venues where
continuity of operation / service is paramount.
Installation of the multiple heat pumps follows the same procedure as single heat pump described
above. It is only necessary to install the heat pumps in parallel connection. Serial connection would
significantly decrease the heating/cooling capacity and efficiency of heat pumps second in line. It is
advised to insert individual valves into connecting water piping for each single heat pump. This will
