2.3 I Operaon
2.3.1 Recommendaons prior to start
• Check that there are no tools or other foreign objects in the appliance.
• The top panel that provides access to the technical secon must be put in place.
• Check that the appliance is stable.
• Check that the electrical wiring is properly connected to the terminals and the earthing.
• Check that the hydraulic correcons are correctly ghtened and that there are no leaks.
2.3.2 Operaon
• Acvate the ltraon pump (if heang priority is not acvated) to turn on the water ow : check that the water is
circulang correctly in the heat pump and that the ow rate is adequate.
• Set the valves as follows: valve B wide open, valves A, C, D and E closed.
: Water inlet valve
: By-pass valve
: Water outlet valve
: Water inlet adjustment valve (oponal)
: Water outlet adjustment valve
(oponal)
• An incorrect by-pass seng may cause the heat pump to malfuncon.
• Close valve B gradually so that the lter pressure is increased by 150g (0.150 bars).
• Open valves A, C and D fully then valve E by half (the air which has built up in the heat pump condenser and the
ltraon circuit will bleed out). If valves D and E are not present, open valve A wide and close valve C by half.
• Connect the power supply to the heat pump (dierenal switch and circuit-breaker), see §”1.3 I Electricity supply
connecons”.
• Press once to turn on the screen.
• If needed, press for 3 seconds to unlock the keypad.
• Adjust the clock, see §”2.4.2 Seng the me (clock)”, page 15.
• Select a mode, see § “2.4.4 Choosing an operang mode”.
• Set the desired temperature (called the "setpoint"), see § “2.4.5 Adjusng the temperature setpoint”.
The heat pump’s compressor will start up aer few minutes.
To check if the heat pump is correctly operang, aer the start-up steps :
• Shut down the water circulaon temporarily (by stopping the ltraon or closing valve A or C) to check that the
appliance stops aer a few seconds (via the acvaon of the ow switch), or,
• Reduce the setpoint temperature to below the water temperature to check that the heat pump stops operang.
