Caution.
Risk of material damage caused by incomplete installation.
This drawing is a basic representation and does not replace complete planning. This drawing does not
contain all of the required valves and safety fittings for a complete installation.
▶Observe the applicable national and international laws, standards and guidelines.
▶When planning, installing and subsequently operating this system, you must observe all the install-
ation and operating instructions available for the product, the relevant accessories and for any other
component.
▶The responsibility for design lies with the responsible company.

2 Installation checklist
You must observe all the operating and installation instructions included with the system components.
Work Comments/settings
1 Comply with the conditions for the installation environment 1. Minimum volume of the installation room 1.60 m³
2. Environmental temperature 7 °C –40 °C
3. Frost-proof
4. Dry
2 Install the heat pump on a wall that has sufficient load-bearing capa-
city
Weight of the heat pump: 59 kg
3 Comply with the specified minimum clearances For free spaces for maintenance work, see the installa-
tion instructions for the relevant system components
4 Observe the position of the VRC 700 in the living room or main control room
5 Check the brine circuit for leak-tightness

Commissioning checklist 3

Work Comments/settings
6 Insulate the brine pipes in the house so that they are vapour-diffu-
sion-tight
Prevent condensation.
7 Use cold pipe clips to install the brine pipes in the house Prevent thermal bridges.
8 Use the correct brine fluid Monoethylene glycol, essential for fault-free operation.
9 Use the correct mixing ratio of monoethylene glycol to water 3:7, efficient operation only when the defined mixing ratio
is used
10 Use a refractometer to check the mixing ratio Efficient operation only when the defined mixing ratio is
used
11 Choke the output of the filling pump Reduce the penetration of air in the brine circuit.
12 Sufficiently dimension the gas-fired boiler's expansion vessel for the
heating circuit
No expansion vessel present in the heat pump.
13 Connect the heat pump via a separately fused plug socket Observe the connection conditions in accordance with
the data plate.
14 Use connection terminals when connecting multiple conductors Prevent communication faults.
15 Install a bus coupler in the VR 32 in the gas-fired boiler The gas-fired boiler is the second participant in the
eBUS.
17 Check all cable connections for tensile strength
16 Visually check all cable connections for damage
