you use and maintain the unit.

General information

The luxury air source heat pump monobloc system consists out of only the outdoor unit in which all
hydraulic parts are located. In this system no refrigerant lines need to be connected which makes the
installation easier for the domestic installer. These units are used for both heating and cooling
applications. The unit can be combined with fan coil units, floor heating, low temperature radiators,
and the domestic hot water tanks.

The unit range consists out of two main versions: a heating/cooling/domestic hot water version and a
heating/cooling version.

Both versions can optionally be delivered with an integrated backup heater for additional heating
capacity during cold outdoor temperatures. The backup heater also serves as a backup in case of

Water pipe-work

Checking the water circuit

The 3-way valve is built-in the unit. So the unit is equipped with the water inlet/outlet for hot water
connection, and the water inlet/outlet for space heating/cooling. The water circuits must be provided by
a licensed technician and must comply with all relevant European and national regulations.

THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER
CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING.

Beforecontinuingtheinstallationoftheunit,checkthefollowingpoints:

• The maximum water pressure is 6 bar.

• Four shut-off valves are not delivered with the unit. To facilitate service and maintenance,

please install one at each water inlet/outlet. Mind position of the shut-off valves. Orientation of
the integrated drain and fill valves is important for servicing.

• Drain taps must be provided at all low points of the system to permit complete drainage of the
circuit during maintenance.

• Make sure to provide a proper drain for the pressure relief valve to avoid any water coming into
contact with electrical parts.

• Air vents must be provided at all high points of the system. The vents should be located at
points which are easily accessible for servicing. An automatic air purge is provided inside the
indoor unit. Check that this air purge valve is not tightened too much so that automatic release
of air in the water circuit remains possible.

• Take care that the components installed in the field piping can withstand the water pressure.

Luxury Air Source Heat Pump-Monobloc System

30

Checking the water volume and expansion vessel pre-pressure

The unit is equipped with an expansion vessel of 10 liters which has a default pre-pressure of 1 bar.
To assure proper operation of the unit, the pre-pressure of the expansion vessel might need to be
adjusted and the minimum and maximum water volume must be checked.

1. Check that the total water volume in the installation is 32 L minimum.

IN MOST AIR CONDITIONING APPLICATIONS THIS MINIMUM WATER VOLUME WILL HAVE A

SATISFYING RESULT. IN CRITICAL PROCESSES OR IN ROOMS WITH A HIGH HEAT LOAD THOUGH,
EXTRA WATER VOLUME MIGHT BE REQUIRED

2. Using the table below, determine if the expansion vessel pre-pressure requires adjustment.

3. Using the table and instructions below, determine if the total water volume in the installation is
below the maximum allowed water volume.

check if the water volume is lower than

maximum allowed water volume (use graph

below)

Expansion vessel of the unit too small for the
installation.

Calculating the pre-pressure of the expansion vessel

The pre-pressure (Pg) to be set depends on the maximum installation height difference (H) and is
calculated as follows:
Pg = (H/10+0.3) bar

Checking the maximum allowed water volume

To determine the maximum allowed water volume in the entire circuit, proceed as follows:

1. Determine for the calculated pre-pressure (Pg) the corresponding maximum water volume using the

graph below.

2. Check that the total water volume in the entire water circuit is lower than this value.

If this is not the case, the expansion vessel inside the indoor unit is too small for the installation.

Luxury Air Source Heat Pump-Monobloc System

31

Setting the pre-pressure of the expansion vessel

When it is required to change the default pre-pressure of the expansion vessel (1 bar), keep in mind the
following guidelines:

- Use only dry nitrogen to set the expansion vessel pre-pressure.

- Inappropriate setting of the expansion vessel pre-pressure will lead to possible malfunctioning
of the system. Therefore, the pre-pressure should only be adjusted by a licensed installer.

Connecting the water circuit

Water connections must be made in accordance with the outlook diagram delivered with the unit,
respecting the water in- and outlet

BE CAREFUL NOT TO DEFORM THE UNIT PIPING BY USING EXCESSIVE FORCE WHEN CONNECTING
THE PIPING. DEFORMATION OF THE PIPING CAN CAUSE THE UNIT TO MALFUNCTION.

Ifair,moistureordustgetsinthewatercircuit,problemsmayoccur.



Therefore, always take into account the following when connecting the water circuit:

• Use clean pipes only.

• Hold the pipe end downwards when removing burrs.

• Cover the pipe end when inserting it through a wall so that no dust and dirt can enter.

• Use a good thread sealant for the sealing of the connections.

• The sealing must be able to withstand the pressures and temperatures of the system.

• When using non-brass metallic piping, make sure to insulate both materials from each other to

prevent galvanic corrosion.

• Because brass is a soft material, use appropriate tooling for connecting the water circuit.
Inappropriate tooling will cause damage to the pipes.

Luxury Air Source Heat Pump-Monobloc System

THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER
CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING.

NEVER USE ZN-COATED PARTS IN THE WATER CIRCUIT. EXCESSIVE CORROSION OF THESE PARTS
MAY OCCUR AS COPPER PIPING IS USED IN THE INTERNAL WATER CIRCUIT OF THE UNIT.

WHEN USING A 3-WAY VALVE OR A 2-WAY VALVE IN THE WATER CIRCUIT.
THE RECOMMENDED MAXIMUM CHANGEOVER TIME OF THE VALVE SHOULD BE LESS THAN 60

SECONDS.

Charging water

1. Connect the water supply to a drain and fill valve.

2. Make sure the automatic air purge valve is open (at least 2 turns).

3. Fill with water until the water manometer indicates a pressure of approximately 2.0 bar. Remove air
in the circuit as much as possible using the air-purge valves. Air present in the water circuit might
cause malfunctioning of the optional backup heater.

4. Regarding units with an optional backup heater:
Check that the backup heater vessel is filled with water by opening the pressure relief valve. Water
must flow out of the valve.

NOTE

• During filling, it might not be possible to remove all the air in the system. Remaining air will be
removed through the automatic air purge valves during first operating hours of the system.
Additional filling with water afterwards might be required.

• The water pressure indicated on the water manometer will vary depending on the
water-temperature (higher pressure at higher water temperature).

• However, at all times water pressure should remain above 0.3 bar to avoid air entering the
circuit.

• The unit might dispose some excessive water through the pressure relief valve.

• Water quality must be according to EN directive 98/83 EC.

Piping insulation

The complete water circuit, inclusive all piping, must be insulated to prevent condensation during
cooling operation and reduction of the cooling and heating capacity.
If the temperature is higher than 30°C and the humidity is higher than RH 80%, then the thickness of the
sealing materials should be at least 20 mm in order to avoid condensation on the surface of the sealing.

1). ON/OFF control signal

When the signal is on (closed), the Heat Pump can work. The running mode will be decided by the
setting of the wired controller. The heat pump will not monitor the setting temperature of the wired
controller.
If the signal is off (open), the Heat Pump can’t work.
But if there is domestic hot water requirement the domestic hot water will not be affected by the
external signal. It will always work as per the setting of wired controller of the heat pump.

2). 0~10V voltage control signal

The external controller gives a signal of 0 to +10V, the heat pump will produce water with different
temperature according to a voltage-water temperature table. Once this control method is in force, the
external signal will control the setting outlet temperature of space heating/cooling, the temperature
setting of the wire controller is not in force anymore.
This control signal is for space heating and space cooling modes.
