All piping should be thermally insulated,
especially the connecting pipes from the Pilot
to the Heat Pump.
BCP = Boiler circulator pump (not supplied)
EV = Expansion vessel (not supplied)
SV = Sludge valve
CV = Check valve
BCV = Boiler check valve (not supplied)
• Fit the tee along with the manual air valve onto the outgoing water outlet of the Heat Pump.
• Install two 30mm Ø  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  exible pipe.
These  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).
The Heat Pump is equipped with a hydraulic
pressure relief valve set at 2.5 bars. A service
pressure below this value should be maintained.

In order to ensure that the  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.
