6.9.3 Checking the system
WARNING
Danger to life from electric shock!
The devices are operated with 230-V or 400-V alternating current. Improper installation
can present a danger to life from electric shock as well as a danger of fire occurring due to
superheat.
► Ascertain before beginning checking that the power supply is switched off and secured
against unintended switch-on.

Note
Instructions for operating the devices through the operating unit are given in the operating
instructions of the respective devices as well as in the appendix to this manual
from the operating instructions (H-Generation), p.
Carry out the following steps to check the completely installed system, with the power supply
switched off:
1. Check if the cooling circuit is tight in the indoor and outdoor unit or in the compact device.
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 pipelines 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
(→ 7.1 Checking of the water pressure, p.
5. Check the functioning of the pressure relief valve
valve, p. 199).
6. Check the initial pressure of the expansion vessel.
Observe the specifications for the dimensioning of the expansion vessel
(→ 5.3.5 Expansion vessel, p.
integration, p. 100).
7. Check the functioning of the FI switch
p. 200).
8. Once you have concluded all checks with positive results, perform a test run to ensure
that no malfunctioning will occur after commissioning.

6.9.4 Carrying out a test run
i
Note
Instructions for operating the devices through the operating unit are given in the operating
instructions of the respective devices as well as in the appendix to this manual
from the operating instructions (H-Generation), p.
Carry out the following steps to perform a test run of the system:
1. Switch on the power supply.
2. Switch on the FI switch of the indoor unit or compact device and through the operating
unit also the heat pump; (while doing this, 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 (CP) such that the
water pressure is in the normal operating range; (while doing this, 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 specialist dealer.
4. Check whether the water flow rate lies within the model-specific limits
data (split systems), p. 16,
→ 5.3 Hydraulics, p. 100).
If necessary, adjust the water flow rate and/or the maximum rotation speed of the circula-
tion pump through the pump control (while doing this, follow the instructions given in the
operating instructions of the respective device).
5. Reset the overload protection if necessary
protection, p. 201):
6. Switch off the heat pump again to terminate the test run.
7. Clean the dirt catcher immediately thereafter
p. 200).
8. Once you have concluded the test run with positive results, you can program the de-
vice 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 end-customer and their training in
the operation of the device.
6.9.5 Carrying out a system transfer and familiarisation
Carry out the following steps for system handover and instruction:
1. Fill in the commissioning report. Make sure again that all installation and commissioning
work has been carried out fully and correctly.
2. Hand over to the end-customer all documents and instruct him to keep the documents
safe. Explain to him the operation based on the operating instructions of the respec-
tive device and sign the instructions report and acceptance certification jointly with the
customer.
