EWAQ+008BAVP
Packaged air-cooled water chillers and packaged air to water heat
pumps
4P478610-1 – 2017.02
INFORMATION
▪ To purge air, use all air purge valves present in the
system. This includes the manual air purge valve of the
outdoor unit, as well as any field-supplied valves.
▪ If the system contains a backup heater, also use the air
purge valve of the backup heater.
▪ If the system contains valve kit EKMBHBP1, it is
required to – during the air purge – manually switch the
position of the valve kit's 3‑way valve by turning its
knob, this to prevent air from remaining in the bypass.
For more information, refer to the instruction sheet of
the valve kit.

To perform a test run
Prerequisite:
Make sure that the leaving water temperature home
page and room temperature home page are turned OFF.
1
Set the user permission level to Installer. See
"To set the user

INFORMATION
When starting up the system in a cold climate, and NO
backup heater kit was installed, it may be required to start
up with a small water volume. To do this, gradually open
the heat emitters. As a result, the water temperature will
gradually rise. Monitor the inlet water temperature ([6.1.6]
in the menu structure) and make sure it does NOT drop
below 15°C.
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.

6.2.4
To perform an underfloor heating screed
dryout
Prerequisite:
Make sure there is ONLY 1 user interface connected
to your system to perform an underfloor heating screed dryout.
Prerequisite:
Make sure that the leaving water temperature home
page and room temperature home page are turned OFF.
1
Go to [A.7.2]:
> Installer settings > Commissioning > UFH
screed dryout.
2
Set a dryout program.

Result:
The underfloor heating screed dryout starts. It stops
automatically when done. To stop it manually, press
, select OK
and press
.
NOTICE
To perform an underfloor heating screed dryout, room frost
protection needs to be disabled ([2‑06]=0). By default, it is
enabled ([2‑06]=1). However, due to the "installer-on-site"
mode (see "Checklist before commissioning"), room frost
protection will be automatically disabled for 36 hours after
the first power-on.
If the screed dryout still needs to be performed after the
first 36 hours of power-on, manually disable room frost
protection by setting [2‑06] to "0", and KEEP it disabled
until the screed dryout has finished. Ignoring this notice will
result in cracking of the screed.
NOTICE
For the underfloor heating screed dryout to be able to start,
make sure the following settings are met:
▪ [4‑00]=1
▪ [C‑02]=0
▪ [D‑01]=0
▪ [4‑08]=0
▪ [4‑01]≠1

Once the test run is finished and the unit operates properly, please
make sure the following is clear for the user:
▪ Fill in the installer setting table (in the operation manual) with the
actual settings.
▪ Make sure that the user has the printed documentation and ask
him/her to keep it for future reference. Inform the user that he can
find the complete documentation on the url as earlier described in
this manual.
▪ Explain the user how to properly operate the system and what to
do in case of problems.
▪ Show the user what to do in relation to maintaining the unit.
