3. Check that no refrigerant is escaping. Check in particu-
lar all of the screwed connections and valves.
4. Screw on both covering caps. Tighten the covering
caps.
5.10 Completing work on the refrigerant circuit
1. Disconnect the refrigerant fitting from the maintenance
connection.
2. Screw the covering cap onto the maintenance connec-
tion.
3. Attach thermal insulation to the refrigerant connections
for the outdoor unit.
4. Attach thermal insulation to the refrigerant connections
for the indoor unit.
5. Fill out the sticker for the refrigerant volumes. This is
located on the left beside the service valves. Note down
the refrigerant volume added at the factory (see data
plate), the additional refrigerant volume added and the
total refrigerant volume.
6. Enter the data in the service book.
7. Install the cover for the service valves.

6.1 Preparing the electrical installation
Danger!
Risk of death from electric shock as a res-
ult of an improper electrical connection!
An improper electrical connection may neg-
atively affect the operational safety of the
product and result in material damage or per-
sonal injury.
▶
Only carry out the electrical installation if
you are a trained competent person and
are qualified for this work.
1. Observe the technical connection conditions for con-
necting to the energy supply company's low-voltage
network.
2. Determine whether the energy supply company lockout
function has been provided for the product, and how
the power supply for the product should be designed,
depending on the type of shutdown.
3. Use the data plate to determine whether the product
requires a 1~/230V or a 3~/400V electrical connection.
4. Use the data plate to determine the product's rated cur-
rent. Derive the suitable cable cross-sections for the
electrical wires from this.
5. Prepare the routing of the electrical wires from the
building and through the wall duct to the product.
6.2 Requirements for electrical components
▶
Flexible hose lines that are suitable for routing outdoors
must be used fr the power supply. The specification must
comply with the standard 60245 IEC 57 with the abbrevi-
ation H05RN-F as a minimum.
▶
The electrical partitions (circuit breakers) must have a
contact gap of at least 3 mm.
▶
For the electrical fuse protection, slow-blow fuses (circuit
breakers) with C characteristics must be used. With a
three-phase power supply, the fuses must be three-pole
switching.
▶
To protect people, type B universal-current-sensitive re-
sidual-current circuit breakers must be used if these are
stipulated for the installation site.
6.3 Installing components for the energy supply
company lockout function
If the energy supply company lockout function has been
provided, the heat generation from the heat pump can be
switched off intermittently by the energy supply company.
The unit can then be shut down in two ways, depending on
the specifications from the energy supply company:
–
The signal for the shutdown is then fed to connection S21
for the indoor unit (electronically controlled shutdown).
–
The signal for the shutdown is fed to a partition that is
installed on-site in the meter box (hard shutdown).
Condition : Energy supply company lockout function provided
▶
Install and wire additional components in the building's
meter/fuse box.
▶
To do this, follow the installation instructions for the in-
door unit.
6.4 Opening the electronics box
1. Undo the two screws on the lower edge.
2. Release the cover by lifting it out of the stop.
6.5 Stripping the electrical wire
1. If required, shorten the electrical wire.
30 mm
≤
2. Strip the electrical wire as shown in the figure. In doing
so, ensure that the insulation on the individual conduct-
ors is not damaged.
6.6 Establishing the power supply, 1~/230V
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 253 V, elec-
tronic components may be damaged.
▶
Ensure that the nominal voltage of the 1-
phase mains is 230 V (+10%/-15%).
▶
Determine the type of connection:
