7 Finishing the outdoor unit
installation
7.1 To check the insulation resistance
of the compressor
NOTICE
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance over the poles can
drop, but if it is at least 1 MΩ, then the unit will not break
down.
▪ Use a 500 V mega-tester when measuring insulation.
▪ Do NOT use a mega-tester for low voltage circuits.
1 Measure the insulation resistance over the poles.
If Then
≥1 MΩ Insulation resistance is OK. This procedure
is finished.
<1 MΩ Insulation resistance is not OK. Go to the
next step.
2 Turn ON the power and leave it on for 6 hours.
Result: The compressor will heat up and evaporate any
refrigerant in the compressor.
3 Measure the insulation resistance again.
8 Configuration
INFORMATION
Heating is only applicable in case of reversible models.
8.1 Overview: Configuration
This chapter describes what you have to do and know to configure
the system after it is installed.
NOTICE
This chapter explains only the basic configuration. For
more detailed explanation and background information,
see the installer reference guide.
Why
If you do NOT configure the system correctly, it might NOT work as
expected. The configuration influences the following:
▪ The calculations of the software
▪ What you can see on and do with the user interface
How
You can configure the system via the user interface.
▪ First time – Configuration wizard. When you turn ON the user
interface for the first time (via the unit), the configuration wizard
starts to help you configure the system.
▪ Restart the configuration wizard. If the system is already
configured, you can restart the configuration wizard. To restart the
configuration
wizard, go to Installer settings >
Configuration wizard . To access Installer settings , see
"8.1.1 To access the most used commands" [ 4 27].
▪ Afterwards. If necessary, you can make changes to the
configuration in the menu structure or the overview settings.
INFORMATION
When the configuration wizard is finished, the user
interface will show an overview screen and request to
confirm. When confirmed, the system will restart and the
home screen will be displayed.
Accessing settings – Legend for tables
You can access the installer settings using two different methods.
However, NOT all settings are accessible via both methods. If so,
the corresponding table columns in this chapter are set to N/A (not
applicable).
Method Column in tables
Accessing settings via the breadcrumb in the
home menu screen or the menu structure .
To enable breadcrumbs, press the button
in the home screen.
