1 Remove one of the side panels. 2 Cut out the rubber grommet. 3 Pull the drain hose through the hole. 4 Reattach the side panel. Ensure the water can flow through the

drain tube.

It is recommended to use a tundish to collect the water.

Option 1: Through the left side panel

Option 2: Through the right side panel

4 Piping installation

4.1 Connecting refrigerant piping

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

4.1.1 To connect the refrigerant piping to the indoor unit

Minimum flow rate

Check that the minimum flow rate in the installation is guaranteed in all conditions. This minimum flow rate is required during defrost operation. For this purpose, it is recommended to use an overpressure bypass valve (field supply).

Minimum required flow rate

12l/min

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.

See the recommended procedure as described in "7.2 Checklist

during commissioning"[424].

4.3 Connecting water piping

4.3.1 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.

1 Connect the space heating water in and out pipes to the indoor

unit.

2 Connect the domestic hot water in and out pipes to the indoor

unit.

NOTICE

A pressure relief valve (field supply) with an opening pressure of maximum 10bar (=1MPa) must be installed on the domestic cold water inlet connection in accordance with the applicable legislation.

4.3.2 To connect the recirculation piping

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

1 Remove the top panel from the unit, see "3.2.1To open the

indoor unit"[45].

2 Cut out the rubber grommet on top of the unit, and remove the

stop. The recirculation connector is placed below the hole.

3 Route the recirculation piping through the grommet and connect

it to the recirculation connector.

4 Reattach the top panel.

4.3.3 To fill the water circuit

To fill the water circuit, use a field supply filling kit. Make sure you comply with the applicable legislation.

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

NOTICE

It is recommended to install shut-off valves on the space heating/cooling water in and out connections, as well as on the domestic cold water in and domestic hot water out connections. These shut-off valves are field supplied.

NOTICE Overpressure bypass valve (field supply). We

recommend to install an overpressure bypass valve in the space heating water circuit. Mind the minimum flow rate when adjusting the overpressure bypass valve setting.

NOTICE

Install air purge valves at all local high points.

INFORMATION

Make sure both air purge valves (one on the magnetic filter and one on the backup heater) are open.

4.3.4 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.

4.3.5 To insulate the water piping

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

CAUTION

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

NOTICE

The distance between the high voltage and low voltage cables should be at least 50mm.

WARNING

Make sure that the electrical wiring does NOT touch the refrigerant gas pipe, which can be very hot.
