4.3 Electric connection
4.3.1 Connection to the plug adapter
IMPORTANT: The heat pump is supplied with a flexible cord with a fork, for connection
to the 230V/50Hz plug adapter. The plug adapter´s installation, protection and use of
the current protector with 30 mA actuating current , must be in accordance with the
related technical requirements (STN 33 2000).
4.3.2 Fixed electric connection
IMPORTANT: The fixed electric connection of the heat pump means interference with
its electric installation, which should be performed by a specialised technician and must
be in accordance with the following requirements:
a)
The heat pump together with the power supply of the filtration pump, must be connected through
a single circuit-breaker and switch, or if appropriate, through the time switch, for regular switching
ons. The dimensioning of the power supply must be sufficient (the suggested cross section of the
conductors is 3 x 2,5 mm
2
) and it must be equipped with a current protector (with the actuating
current up to 30mA). The mains´characteristics (voltage and frequency) must be in compliance
with the operating parameters of the device.
b)
The electric connection must be performed by a specialised technician and must be in accordance
with the valid electrotechnical requirements.
c)
The electric installation of the heat pump must be grounded appropriately.The grounding
distributor´s impedance must be in compliance with the valid electrotechnological requirements.
d)
The feed and control cables must be connected and imbedded in the simpliest and most
understandable way, without any needless crosses.
e)
It is important to carefully check and measure the electric installation before putting it into
operation.
f)
The suggested protection is stated in the chart below:
