Electric heater Aqua compact
Electric installation
After a complete pipe installation, the heater is electrically connected. It must be connected over two contactors, see the
connections diagram.
Electric installation may be performed only by a qualified electrician.
Installation must be performed so that the heater cannot be switched on without the system filter pump being in operation
(the operating current of the heater contactor is controlled over the pump's motor protection).
