Checks During And After First Commissioning - Olimpia splendid Sherpa Aquadue S2 E Small Instructions Pour L'installation, L'emploi Et L'entretien

• The area of respect has been observed.
• The hydraulic connections has been carried out according to the instruction manual.
• The hydraulic system has been loaded and vented.
• The interception valves of the hydraulic circuit are open.
• If a boiler is present in the system, check that the non-return valves have been installed on the water
inlets to the heat pump and to the boiler to avoid reductions in water flow rate in the system and entrance
of too hot water in the heat pump.
• The electrical connections have been carried out correctly.
• The tolerance of the power supply voltage does not exceed +/- 10% with respect to the value indicated
in the nameplate.
• The three-phase power supply for three-phase models has a maximum unbalance of 3% between the
phases.
• The ground connection has been performed correctly.
• Tightening of all the electrical connections has been performed correctly.
• The section of the power cables is suitable for the absorption of the appliance and for the length of the
performed connection.
• Every object has been removed, in particular shavings, bits of wire and screws.
• Check that all cables are connected and that all electrical connections are solid.
• Both the service valve of the gas pipe and the one of the liquid pipe (fig. 14 - rif.34) are open.
• Ask the customer to be present at the operational testing.
• Show the contents of the instruction manual to the customer.
• Hand the instruction manual and the warranty certificate over to the customer.

4.2 - CHECKS DURING AND AFTER FIRST COMMISSIONING

Once start-up has been performed, check that:
• The current absorbed by the compressor is lower than the maximum one indicated in the plate data (see
table in paragraph 3.6).
• During operation of the compressor, electrical voltage corresponds to the rated value +/-10%.
• The three-phase power supply has a maximum unbalance of 3% between the phases.
• The noise level of the three-phase compressor is not abnormal.
• The appliance works within the advised operating conditions (see paragraph "2.4").
• The hydraulic circuit is completely de-aerated.
• The air-water heat pump stops and then reactivates.
• The difference between inlet water temperature and outlet water temperature of the conditioning system
must be included between 4 and 7°C.
• If the difference between inlet water temperature and outlet water temperature should be lower
than 4°C, set a lower speed of the circulator.
• If, on the contrary, it should be higher than 7°C, check for the opening of all the valves on the
system and set, if possible, a higher speed of the circulator or insert an inertial accumulation
(which acts as hydraulic separator) between the unit and the system and add an external pump
which feeds the system.
• After adjusting the water flow rate of the conditioning circuit, adjust the flow rate of the DHW heat pump
circuit evaporator by means of the flow regulator (fig.4 - rif.14).
The flow regulator must be set to 5 l/min by rotating the ferrule on the base of the graduated scale.
• To adjust the temperature of blended water, proceed as described in fig. 8.
• Check the adjusted temperature by measuring water temperature at the tap nearest to the valve.
Verification of outlet water temperature must be carried out when domestic water reaches the
temperature set on the electronic control (set point reached).
Temperature must be checked annually to make sure that the valve adjustment is correct.
