GENERAL
Only a competent person may carry out the installation.
The installer must follow applicable rules and regulations
and recommendations from the supplier.
7.1
INFORMATION ABOUT THE HEAT PUMP
6-11 Combi are heat pumps with integrated hot water cylinders.
6-11 System are heat pumps designed to be supplemented with an
external hot water cylinder e.g. our 280 litre solar compatible.
7.2
APPLICATION AREA
The heat pump must only be used in a sealed hot water heating system
according to BS EN 12828.
Other forms of use are not permitted. We take no responsibility for
damage occurring due to non-permitted use.

7.4
TYPE PLATE
The type plate is located on the roof plate of the heat pump. Information
about the heat pump's output, part number, serial number and date of
manufacture is stated there.
7.5
TRANSPORT AND STORAGE
The heat pump should always be transported and stored in an upright
position. However, the heat pump may be tilted temporarily, but must
not be laid down.
The outer cover plates should be removed to avoid damage if the heat
pump is transported without the supplied transport pallet.
The heat pump must not be stored at below zero temperatures.
7.6
POSITIONING THE HEAT PUMP
▶ The heat pump is placed indoors, on a level and stable surface that
withstands a weight of at least 500 kg.
▶ Adjust the rubber feet so the heat pump does not lean.
▶ The ambient temperature around the heat pump must be between
+10 °C and +35 °C.
▶ The installer should take sound propagation into consideration when
positioning the heat pump.
▶ The heat pump cylinder must be installed in line with The Building
Regulations 1991 (England & Wales) Requirements G3, L1 and
Regulation 7.
7.7
CHECKS BEFORE INSTALLATION
▶ Installation of the heat pump should be performed by a competent
person.
▶ Before the heat pump is commissioned, the heating system, hot water
cylinder and the collector circuit system, including the heat pump,
must be filled and vented.
▶ Check that all pipe connections are intact and have not shaken loose
during transportation.
▶ Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.

▶ Heat pump installation, energy drilling and collector installation must
follow applicable regulations.
7.8
CHECKLIST
Each heat pump installation is unique. The following
checklist will give you a general description of how the
installation should be carried out.
1. Position the heat pump on an even base. Adjust the height using the
adjustable feet.
2. Install the incoming and outgoing pipes for the heat pump, as well as
the expansion vessel.
3. Fit the filling unit, particle filters and valves.
4. Connect the heating unit to the heating system.
5. Install the outdoor sensor and possible room controllers.
6. Fill and vent the heating and collector systems before commissioning.
7. Carry out the external connections.
8. Connect the heating installation to the power supply.
9. Commission the heating installation by making all the necessary
settings on the control panel.
10. Check the heating installation after commissioning.
11. Top up more collector circuit fluid, if required.
7.9
CAN-BUS
CAUTION: Do not mix up the 12 V and CAN-BUS
connections!
The processors will be damaged beyond repair if 12 V is
connected to the CAN-BUS.
▶ Ensure that the four cables which are to be connected
to the contacts on the printed circuit boards are made
with their corresponding markings.
The printed circuit boards in the heat pump, and accessories board if
applicable, are connected via the CAN-BUS communication line. The
CAN (Controller Area Network) is a system that facilitates
communication between microprocessor-based modules/printed
circuit boards.
A room controller is available as an accessory and must be connected by
a CAN-BUS cable.
Suitable cable for external laying is cable type LIYCY (TP) 2x2x0.5.
The cable must be twisted pair and screened. The screen must only be
earthed at one end and to the chassis.
Maximum cable length is 30 m.
The CAN-BUS cable must not be routed together with the mains cable
that carry 230 V or 400 V. The minimum clearance is 100 mm. Routing
of these cable together with the sensor cables is not permitted.
The connection between the circuit boards is by four wires, because the
12V-supply between the circuit boards must also be connected. The
circuit boards have markings for both the 12V and CAN-BUS
connections.
