Carrying Out A Test Run - Panasonic Aquarea WH-ADC0309J3E5 Planning And Installation Manual

Carry out the following steps to check the completely installed system, with the power supply
switched off:
1. Check if the refrigerant circuit is tight in the indoor and outdoor unit or in the mono-bloc unit.
Deficiencies and leakages must be repaired.
2. Check whether all electrical cable installations have been carried out correctly and all
connections are firm. Deficiencies, if any, must be repaired.
3. Check whether all pipes have been properly installed and are tight and whether the water
system is properly filled with water and vented. Deficiencies and leakages must be repaired.
4. Check the water pressure in the system by means of the integrated manometer
(→
5. Check the functioning of the pressure relief valve (→
p. 196).
6. Check the initial pressure of the expansion vessel.
Observe the specifications for the dimensioning of the expansion vessel (→
vessel, p.
7. Check the functioning of the RCCB (→
8. Once you have concluded all checks with positive results, perform a test run to ensure that
no malfunctioning will occur after commissioning.

Note
Instructions for operating the devices using the remote controller are given in the operating
instructions of the respective devices.
Carry out the following steps to perform a test run of the system:
1. Switch on the power supply.
2. Switch on the residual current circuit breaker (RCCB) of the indoor unit or mono-bloc unit
and use the remote controller to switch on the heat pump (to do so, follow the instructions
given in the operating instructions of the respective device).
3. Check the water pressure again.
Under normal operating conditions, the measured value of the manometer should be
between 0.5 and 3 bar (0.05 and 0.3 MPa).
If necessary, adjust the rotational speed level of the circulation pump such that the water
pressure is in the normal operating range (to do so, follow the instructions given in the
operating instructions of the respective device).
If the pressure does not reach the normal operating range by setting the rotation speed level,
please contact your Panasonic dealer.
4. Check whether the water flow rate lies within the model-specific limits (→

If necessary, adjust the water flow rate and/or the maximum rotational speed of the
circulation pump with the pump control (to do so, follow the instructions given in the
operating instructions of the respective device).
5. Reset the overload protection if necessary (→

6. Switch off the heat pump again to terminate the test run.
7. Clean the strainer immediately thereafter (→
8. Once you have concluded the test run with positive results, you can program the device for
the desired operation on the basis of the operating instructions of the respective device.
9. Thereafter, perform the handover of the system to the customer and his instruction in the
operation of the device.
