• Fit the tee along with the manual air valve onto the outgoing water outlet of the Heat Pump.
• Install two 30mm Ø fl exible pipes of at least 1.5m in length to the water inlet and outlet holes on the Heat Pump (outside the
building).
• Carefully insulate the pipes to minimise heat loss.
• Take care to respect a 240mm Ø minimum radius of curvature so as to avoid damaging or bending the fl exible pipe.
These fl exible pipes are used to decouple the Pilot from the rest of the hydraulic installation (they MUST be connected as
the Heat Pump stands on silent blocks).

In order to ensure that the fl uids can circulate properly it is advisable to check that the sizing is properly adapted to the circuit between the
Heat Pump and the Pilot.
The Heat Pump is equipped with a hydraulic
pressure relief valve set at 2.5 bar. A service
pressure below this value should be maintained.
