Do NOT use excessive force when connecting the piping.Deformation of the piping can cause malfunctioning of theunit. Make sure that the tightening torque does NOTexceed 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. Mindtheir position: the integrated drain valves will only drain the side ofthe circuit on which they are located. To be able to only drain theunit, make sure the drain valves are positioned between the shut‑offvalves and the unit.

a ba Water inletb 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 againstfreezing

Frost can damage the system. To prevent the hydraulic componentsfrom freezing, the software is equipped with special frost protectionfunctions, 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 cannotguarantee protection. It is therefore recommended to add glycol tothe water circuit. The required concentration depends on the lowestexpected outdoor temperature, and on whether you want to protectthe system from bursting or from freezing. To prevent the systemfrom freezing, more glycol is required. Add glycol according to thetable below.

INFORMATION

▪ Protection against bursting: the glycol will prevent thepiping from bursting, but NOT the liquid inside thepiping from freezing.

▪ Protection against freezing: the glycol will prevent theliquid inside the piping from freezing.

Lowest expectedoutdoortemperature

Prevent fromfreezing

–5°C 10% 15%–10°C 15% 25%–15°C 20% 35%–20°C 25% —–25°C 30% —

NOTICE

▪ The required concentration might differ depending onthe type of glycol. ALWAYS compare the requirementsfrom the table above with the specifications provided bythe glycol manufacturer. If necessary, meet therequirements set by the glycol manufacturer.

▪ The added concentration of glycol should NEVERexceed 35%.

▪ If the liquid in the system is frozen, the pump will NOTbe able to start. Mind that if you only prevent thesystem from bursting, the liquid inside might still freeze.

▪ In case of a power supply failure or pump failure, andNO glycol was added to the system, drain the system.

▪ When water is at standstill inside the system, thesystem is very likely to freeze and get damaged.

The types of glycol that can be used depend on whether the systemcontains a domestic hot water tank:

If… Then…The system contains a domestichot water tank

Only use propylene glycol(a)

The system does NOT contain adomestic hot water tank

You can use either propyleneglycol(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 doNOT add glycol that has been exposed to air. Leaving thecap off the glycol container causes the concentration ofwater to increase. The glycol concentration is then lowerthan assumed. As a result, the hydraulic componentsmight freeze up after all. Take preventive actions to ensurea minimal exposure of the glycol to air.

NOTICE

▪ If overpressure occurs, the system will release some ofthe liquid through the pressure relief valve. If glycol wasadded to the system, take adequate measures so as tosafely recover it.

▪ In any case, make sure that the flexible hose of thepressure relief valve is ALWAYS free to releasepressure. Prevent water from staying and/or freezingup inside the hose.

4 Installation

Installation manual

9RBLQ+RDLQ05+07CAV3ROTEX HPSU low temperature monobloc4P417248-1 – 2015.08

WARNING

Due to presence of glycol, corrosion of the system ispossible. Uninhibited glycol will turn acidic under theinfluence of oxygen. This process is accelerated by thepresence of copper and high temperatures. The acidicuninhibited glycol attacks metal surfaces and formsgalvanic corrosion cells that cause severe damage to thesystem. Therefore it is important that:

▪ the water treatment is correctly executed by a qualifiedwater specialist,

▪ a glycol with corrosion inhibitors is selected tocounteract acids formed by the oxidation of glycols,

▪ no automotive glycol is used because their corrosioninhibitors have a limited lifetime and contain silicateswhich can foul or plug the system,

▪ galvanized pipes are NOT used in glycol systems sincethe presence may lead to the precipitation of certaincomponents in the glycol's corrosion inhibitor.

Adding glycol to the water circuit reduces the maximum allowedwater volume of the system. For more information, refer to thechapter "To check the water volume and flow rate" in the installerreference guide.

4.3.3 To fill the water circuit1 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 isopen.

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. Forinstructions, 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 areno more pressure drops.

8 Close the drain and fill valve.

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

4.3.4 To insulate the water pipingThe piping in the complete water circuit MUST be insulated toprevent condensation during cooling operation and reduction of theheating and cooling capacity.

To prevent the freezing of the outdoor water piping during wintertime, 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 higherthan RH 80%, the thickness of the insulation materials should be atleast 20  mm to prevent condensation on the surface of theinsulation.

During winter, protect the water piping and shut‑off valves againstfreezing by adding heat tape (field supply). If the outdoortemperature can drop below –20°C and no heat tape is used, it isrecommended to install the shut‑off valves indoors.

4.4 Connecting the electrical wiringDANGER: RISK OF ELECTROCUTION
