4.3 Connecting the 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. Make sure that the tightening torque does NOT exceed 30N•m.

To facilitate service and maintenance, 2 shut-off valves are provided. Mount the valves on the water inlet and on the 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.

NOTICE

▪ The required concentration might differ depending on

the type of glycol. ALWAYS compare the requirements from the table above with the specifications provided by the glycol manufacturer. If necessary, meet the requirements set by the glycol manufacturer.

▪ 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:

Prevent from bursting

Prevent from freezing

a Water inlet b Water outlet

1 Screw the outdoor unit nuts on the shut-off valves. 2 Connect the field piping on the shut-off valves. 3 In case of connection with the optional domestic hot water tank,

see the installation manual of the domestic hot water tank.

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.

If… Then…

The system contains a domestic hot water tank

The system does NOT contain a domestic hot water tank

(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.

Only use propylene glycol

You can use either propylene

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.

4.3.3 To fill the water circuit

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

9 Disconnect the water supply hose from the drain and fill valve.

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 shut‑off 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 shut‑off valves indoors.

4.4 Connecting the electrical wiring

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

4.4.1 To connect the electrical wiring on the outdoor unit

1 Remove the switch box cover. See "4.1.1To open the outdoor

unit"on page5.

2 Insert the wiring from the back of the unit:

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. For

instructions, see "6Commissioning"on page18.

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.
