2.1 Indoor unit

2.1.1 To remove the accessories from the indoor unit

1 Remove the screws at the top of the unit. 2 Remove the top panel. 3 Remove the screws at the front of the unit. 4 Push on the button on the bottom of the front plate. 5 Remove the front plate.

WARNING: Sharp edges

Take the front plate on the upper part instead of the lower part. Watch your fingers, there are sharp edges on the lower part of the front plate.

3 Preparation

3.1 Preparing the installation site

3.2 Preparing water piping

NOTICE

In case of plastic pipes, make sure they are fully oxygen diffusion tight according to DIN 4726. The diffusion of oxygen into the piping can lead to excessive corrosion.

3.2.1 To check the water volume and flow rate

Minimum water volume

Check that the total water volume in the installation is minimum 10 litre for EHVH04+08 and 20 litre for EHVH11+16, the internal water volume of the indoor unit NOT included.

NOTICE

When circulation in each space heating/cooling loop is controlled by remotely controlled valves, it is important that the minimum water volume is guaranteed, even if all of the valves are closed.

Minimum flow rate

Check that the minimum flow rate (required during defrost/backup heater operation (if applicable)) in the installation is guaranteed in all conditions.

NOTICE

When circulation in each or certain space heating loops is controlled by remotely controlled valves, it is important that the minimum flow rate is guaranteed, even if all valves are closed. In case the minimum flow rate cannot be reached, a flow error 7H will be generated (no heating or operation).

See the installer reference guide for more information.

4.2 Mounting the indoor unit

4.2.1 To install the indoor unit

1 Lift the indoor unit from the pallet and place it on the floor.

2 Slide the indoor unit into position. 3 Adjust the height of the leveling feet to compensate for floor

irregularities. The maximum allowed deviation is 1°.

NOTICE

Do NOT tilt the unit backwards:

2 Connect the gas stop valve from the outdoor unit to the

refrigerant gas connection of the indoor unit.

4.4 Connecting the water piping

4.4.1 To connect the water piping

NOTICE

Do NOT use excessive force when connecting the piping. Deformation of the piping can cause malfunctioning of the unit.

To facilitate service and maintenance, 2 shut-off valves are provided. Mount the valves on the space heating water inlet and space heating water outlet. Mind their position: the integrated drain valves will only drain the side of the circuit on which they are located. To be able to only drain the unit, make sure the drain valves are positioned between the shut‑off valves and the unit.

1 Install the shut-off valves on the space heating water pipes. 2 Screw the indoor unit nuts on the shut-off valve. 3 Connect the domestic hot water in and out pipes to the indoor

unit.

a Space heating water out b Space heating water in c Domestic hot water out d Domestic cold water in (cold water supply)

NOTICE

4.3 Connecting the refrigerant piping

See the outdoor unit installation manual for all guidelines, specifications and installation instructions.

4.3.1 To connect the refrigerant piping to the indoor unit

1 Connect the liquid stop valve from the outdoor unit to the

refrigerant liquid connection of the indoor unit.

Installation manual

It is recommended to install shut-off valves to domestic cold water in and domestic hot water out connections. These shut-off valves are field supplied.

NOTICE

Install air purge valves at all local high points.

NOTICE

A pressure relief valve (field supply) with an opening pressure of maximum 10 bar must be installed on the domestic cold water inlet connection in accordance with the applicable legislation.

4.4.2 To connect the recirculation piping

Prerequisite: Only required if you need recirculation in your system.

1 Loosen and remove the 4 screws that fix the top panel. 2 Remove the top panel from the unit.

3 In case of a unit with a tank capacity of 180 l, remove the

expansion vessel.

4 Remove the top insulation. 5 Cut out part (c) from the top insulation.

6 Connect the recirculation piping to the recirculation connection

(b) and route the piping through the hole at the backside of the unit (a).

3 Make sure that the automatic air purge valve is open (at least 2

turns).

4 Fill the circuit with water until the manometer indicates a

pressure of ±2.0bar.

5 Purge as much air as possible from the water circuit. 6 Close the fill valve. 7 Disconnect the water supply hose from the fill valve.

4.4.4 To fill the domestic hot water tank

1 Open every hot water tap in turn to purge air from the system

pipe work.

2 Open the cold water supply valve. 3 Close all water taps after all air is purged. 4 Check for water leaks. 5 Manually operate the field-installed pressure relief valve to

ensure a free water flow through the discharge pipe.

NOTICE

To operate the system, the domestic hot water tank needs to be filled completely. Turning on the system when the tank is not full can damage the integrated anti-legionella heater and cause electrical errors.

4.4.5 To insulate the water piping

The piping in the complete water circuit MUST be insulated to prevent condensation and reduction of the heating capacity.

If the temperature is higher than 30°C and the humidity is higher than RH 80%, the thickness of the insulation materials should be at least 20 mm to prevent condensation on the surface of the insulation.

4.5 Connecting the electrical wiring

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

4.5.1 To connect the electrical wiring on the indoor unit

1 To open the indoor unit, see "4.1.1To open the indoor unit"on

page5 and "4.1.2 To open the switch box cover of the indoor

7 Reattach the top insulation, expansion vessel (in case of a unit

with a tank capacity of 180l), and casing.

4.4.3 To fill the water circuit

1 Connect the water supply hose to the fill valve.

4.5.2 To connect the main power supply

1 Connect the main power supply.

In case of normal kWh rate power supply

4 Fix the cable with cable ties to the cable tie mountings to

ensure strain relief and to make sure that it does NOT come in contact with the piping and sharp edges.

INFORMATION

To access the domestic hot water temperature sensor, the switch box can be tilted. The switch box should NOT be removed from the unit.

Routing Possible cables (depending on unit type

and installed options)

Low voltage

▪ Preferential power supply contact

▪ User interface

▪ Power consumption digital inputs (field

supply)

▪ Outdoor ambient temperature sensor

(option)

▪ Indoor ambient temperature sensor

(option)

▪ Electrical meters (field supply)

▪ Safety thermostat (field supply)

High voltage power supply

▪ Interconnection cable

▪ Normal kWh rate power supply

▪ Preferential kWh rate power supply

▪ Power supply for anti-legionella heater (in

DHW tank)

▪ Power supply for bottom plate heater

(option)

High voltage control signal

▪ Heat pump convector (option)

▪ Room thermostat (option)

▪ Shut-off valve (field supply)

▪ Domestic hot water pump (field supply)

▪ Alarm output

▪ Changeover to external heat source

▪ Space heating operation control

CAUTION

Do NOT push or place redundant cable length in the unit.

Legend: see illustration below.

In case of preferential kWh rate power supply

Connect X6Y to X6YB.

a Interconnection cable (=main power supply) b Normal kWh rate power supply c Preferential power supply contact

2 Fix the cables with cable ties to the cable tie mountings.

INFORMATION

In case of preferential kWh rate power supply, connect X6Y to X6YB. The necessity of separate normal kWh rate power supply to indoor unit (b) X2M/30+31 depends on the type of preferential kWh rate power supply.

Separate connection to the indoor unit is required:

▪ if preferential kWh rate power supply is interrupted

when active, OR

▪ if no power consumption of the indoor unit is allowed at

the preferential kWh rate power supply when active.

INFORMATION

The preferential kWh rate power supply contact is connected to the same terminals (X5M/3+4) as the safety thermostat. It is only possible for the system to have EITHER preferential kWh rate power supply OR a safety thermostat.
