ELECTRICAL CONNECTION

4.3.1

CONNECTION TO THE MAINS

IMPORTANT: The heat pump is supplied with
requirements of the ČSN 33 2000 standard, including adequate protection and installation of a residual-current
circuit breaker (RCCB) of the actuating current not exceeding 30 mA.
The use of a double socket with common switching (by a switch or a timer) is recommended.
The heat pump ON/OFF switching is described in chapters 5 and 6.
4.3.2

PERMANENT ELECTRICAL CONNECTION

IMPORTANT: In case you decide to connect your heat pump permanently it will mean an intervention
into its wiring that shall be carried out only by a specialist of appropriate technical qualifi cation and the
installation shall meet the following requirements:
(a) The heat pump together with the power supply for the pump of fi ltration unit shall be connected via a separate circuit breaker and switch, or, possibly, a timer for
its regular starting. The supply cable shall be of adequate size (the cable of 3x2.5 mm2 cross section is recommended) and provided with a residual-current circuit
breaker (RCCB) of the actuating current not exceeding 30 mA. The parameters of power network (voltage & frequency) shall comply with the equipment ones.
(b) The electrical connection shall be carried out by a duly qualifi ed technician in compliance with applicable IEC regulations and standards.
(c) The pump wiring shall be properly grounded. The impedance of grounding circuit shall meet applicable IEC regulations and standards.
(d) The power and control cables shall be wired and laid in the simplest and easy to understand way, without any useless crossing.
(e) Before putting it into operation, the wiring system should be carefully checked and measured with the view to eliminating any erroneous connections.
(f) The following table gives the data of recommended protection:
