First Start Of The Heat Pump - Fujitsu NEORE B User Manual Installation Instruction

BIVALENT SOURCE
Heat pumps Neore contain integrated electric boiler of capacity 6kW. The boiler compensates power loss of the
heat pump at extreme conditions. When external bivalent boiler is used, it is necessary to equip it with all safety
elements (temperature protection, pressure valve, el. protection). The added bivalent source is controlled by the
heat pump only passively. It means it must contain its own regulation so that heating water temperature is not
exceeded, e.g. for the floor heating.

9. FIRST START OF THE HEAT PUMP

It is necessary to put water into the circuit before you launch the heat pump. Reach basic pressure 1 - 1.5 bar.
According to water column add 0.1 bar for every meter height of the heating system. Next, it is necessary to bleed
the circuit thoroughly. The bleeding is done by the bleeding screw of the circuit pump or, alternatively, on the upper
threaded piece of the board exchanger. When the circuit pump is switched on, the board exchanger shall be bled
thoroughly. After that its noise is decreased. The circuit pump shall run for 10 minutes at least before the
compressor is switched on. After watering and bleeding electric equipment shall be used.
