2 Installation
2.1 Before installation
The manufacturer shall not be liable for any defects in the equipment
resulting from improper installation or any costs arising thereof.
Any pipe installation associated with the heat pump may be performed
by qualified and trained personnel only.
Check the following before installation:
1. All the necessary hoses and sensors have been delivered.
2. There is sufficient clearance around the heat pump, and the heat pump has been
properly leveled.
3. The connections on top of the unit are intact.
4. The main fuse and the heat pump fuse has the correct rating (see
Technical data
).
5. The brine circuits and the heating circuits have been appropriately installed.
After installation, go through the installation checklist to avoid potential
problems.
2.2 Bivalent operation: use with supplementary heating
In certain cases, the heat pump’s heating capacity needs to be supplemented actively
with an electric immersion heater installed in the storage tank. A typical example is the
high temperature required by radiator systems.
If the heat pump is used with supplementary heating, the heating system must be
sized and adjusted so that the return water temperature is always below +55 °C. The
building’s electrical system needs to be equipped with priority relays (see section
Load
guard ).
Activate supplementary heating from the
Maintenance
menu.
2.3 Installation site requirements
Install the unit and the associated equipment in a warm, dry place.
