Any type of mono-bloc unit
10. Insulate the pipelines and connections according to the locally valid European, national and
170
5. Only for heat pump models of the F Generation: Install an overflow valve, if no hydraulic
disconnection (e.g. hydraulic shunt or buffer tank) has been provided. Take care to set the
overflow valve not for the minimum flow rate, but for the nominal flow rate of the respective
heat pump.
This is only allowable for heat pump models of the F-Generation, because hydraulic
disconnection is necessary for all heat pump models of the G- and H-Generation.
6. If a heat pump with cooling function is used, you may have to install 2-way valves for
switching off the heating circuits in cooling mode.
7. Install the 3-way switchover valve (to be provided on site) to switch over from heating mode
to hot water mode and reverse, if a Panasonic hot water tank is not used. The valve should
by default be opened in the direction of the heating circuit. Moreover, the valve should have
CE conformity and not exceed a peak load of 12 VA.
8. Connect inflow (water out) and return (water in) of the indoor unit or mono-bloc unit to the
heat exchanger of the hot water tank. Take care not to mix up the connections.
9. Install a device for draining the system provided on site.
