To Perform A Test Run - Daikin CHYHBH05AA Installer's Reference Manual

INFORMATION
Start by performing a manual air purge. When almost all
the air is removed, perform an automatic air purge. If
necessary, repeat performing the automatic air purge until
you are sure that all air is removed from the system.
During air purge function, pump speed limitation [9‑0D] is
NOT applicable.
Air purge prerequisites
3 Install air purges on each part of the installation where the pipe
work goes down. (For example on a tank with connections on
top.)
4 Fill the circuit to ±2 bar.
5 Purge all radiators and all other air purges installed on the
circuit.
6 Repeat steps 2 and 3 until purging the radiators and the other
points does NOT longer lead to a pressure drop.
7 Make sure that the leaving water temperature home page, room
temperature home page, and domestic hot water home page
are turned OFF.
When an air bubble blocks the pump and there is no flow, a 7H error
can occur. In this case, stop the air purge function and restart the
operation. This will cause the bubble to leave the pump. Make sure
the pressure in the circuit is ±2 bar and refill if necessary.
To check if the air purge function is finished, monitor the flow rate. If
it stays constant when the pump is running at high or low speed, the
unit is properly purged. To monitor the flow rate, go to [6.1.8].
The air purge function automatically stops after 42 minutes.

INFORMATION
If 2 user interfaces are present, you can start a test run
from both user interfaces.
▪ The user interface used to start the test run displays a
status screen.
▪ The other user interface displays a "busy" screen. You
cannot use the user interface as long as the "busy"
screen is shown.
If the installation of the unit has been done correctly, the unit will
start up during test operation in the selected operation mode. During
the test mode, the correct operation of the unit can be checked by
monitoring leaving water temperature (heating mode) and tank
temperature (domestic hot water mode).
To monitor the temperature, go to [A.6] and select the information
you want to check.
