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 20 litres, the internal water volume of the outdoor unit NOT included.
NOTICE
When circulation in each space heating 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) in the installation is guaranteed in all conditions.
NOTICE
If glycol was added to the water circuit, and the temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the minimum flow rate can be checked by way of the pump test (check that the user interface does NOT display error
7H).
NOTICE
When circulation in each or certain space heating loop 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/operation).

NOTICE
▪ Install a manometer in the system.
▪ Install air purge valves at all local high points.
4.3.2
To protect the water circuit against freezing
Frost can damage the system. To prevent the hydraulic components from freezing, the software is equipped with special frost protection functions, that include the activation of pump, internal heaters, and/ or backup heater operation in case of low temperatures.
However, in case of a power failure, these functions cannot guarantee protection. It is therefore recommended to add glycol to the water circuit. The required concentration depends on the lowest expected outdoor temperature, and on whether you want to protect the system from bursting or from freezing. To prevent the system from freezing, more glycol is required. Add glycol according to the table below.
INFORMATION
▪ Protection against bursting: the glycol will prevent the piping from bursting, but NOT the liquid inside the piping from freezing.
▪ Protection against freezing: the glycol will prevent the liquid inside the piping from freezing.

NOTICE
▪ The added concentration of glycol should NEVER exceed 35%.
▪ If the liquid in the system is frozen, the pump will NOT be able to start. Mind that if you only prevent the system from bursting, the liquid inside might still freeze.
▪ In case of a power supply failure or pump failure, and
NO glycol was added to the system, drain the system.
▪ When water is at standstill inside the system, the system is very likely to freeze and get damaged.
The types of glycol that can be used depend on whether the system contains a domestic hot water tank:
If…
The system contains a domestic hot water tank
Then…
Only use propylene glycol
(a)
The system does NOT contain a domestic hot water tank
You can use either propylene glycol
(a)
or ethylene glycol
(a) Propylene glycol, including the necessary inhibitors, classified as Category III according to EN1717.
WARNING
Ethylene glycol is toxic.
NOTICE
Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concentration is then lower than assumed. As a result, the hydraulic components might freeze up after all. Take preventive actions to ensure a minimal exposure of the glycol to air.
NOTICE
▪ If overpressure occurs, the system will release some of the liquid through the pressure relief valve. If glycol was added to the system, take adequate measures so as to safely recover it.
▪ In any case, make sure that the flexible hose of the pressure relief valve is ALWAYS free to release pressure. Prevent water from staying and/or freezing up inside the hose.
WARNING
Due to presence of glycol, corrosion of the system is possible. Uninhibited glycol will turn acidic under the influence of oxygen. This process is accelerated by the presence of copper and high temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system. Therefore it is important that:
▪ the water treatment is correctly executed by a qualified water specialist,
▪ a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols,
▪ no automotive glycol is used because their corrosion inhibitors have a limited lifetime and contain silicates which can foul or plug the system,
▪ galvanized pipes are NOT used in glycol systems since the presence may lead to the precipitation of certain components in the glycol's corrosion inhibitor.
Adding glycol to the water circuit reduces the maximum allowed water volume of the system. For more information, refer to the chapter "To check the water volume and flow rate" in the installer reference guide.

To fill the water circuit
1
Connect the water supply hose to the drain and fill valve.
2
Open the drain and fill valve.
3
If an automatic air purge valve was installed, make sure it is open.
4
Fill the circuit with water until the manometer (field supply) indicates a pressure of ±2.0 bar.
5
Purge as much air as possible from the water circuit.
INFORMATION
▪ To purge air, use all air purge valves present in the system. This includes the manual air purge valve of the outdoor unit, as well as any fieldsupplied valves.
▪ For the location of the manual air purge valve, see
"Components: Outdoor unit" in the installer reference guide.
▪ If the system contains a backup heater, also use the air purge valve of the backup heater. For the location of this valve, refer to "Components: Backup heater" in the installer reference guide.
▪ For instructions on how to perform an air purge, see
"6.2.1 To perform an air purge" on page 18
.
NOTICE
When purging air with the manual air purge valve of the unit, collect any fluid that might leak out of the valve. If this fluid is NOT collected, it might drip on internal components and damage the unit.
6
Refill the circuit until the pressure is ±2.0 bar.
7
Repeat steps 5 and 6 until no more air is purged and there are no more pressure drops.
8
Close the drain and fill valve.
9
Disconnect the water supply hose from the drain and fill valve.
4 Installation
4.3.4
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.
To prevent the freezing of the outdoor water piping during winter time, the thickness of the sealing material MUST be at least 13 mm
(with λ=0.039 W/mK).
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.
During winter, protect the water piping and shutoff valves against freezing by adding heat tape (field supply). If the outdoor temperature can drop below –20°C and no heat tape is used, it is recommended to install the shutoff valves indoors.
