4.1.3 Requirements and recommendations for the hydraulic circuit

• The storage capacity of the tank has to meet with the daily

consumption in order to avoid stagnation of water.

• Fresh water must circulate inside the DHW tank water

circuit at least one time per day during the rst days after the installation has been performed. Additionally, ush the system with fresh water when there is no consumption of DHW during long periods of time.

• Try to avoid long runs of water piping between the tank

and the DHW installation in order to decrease possible temperature losses.

• When using the indoor unit in combination with the YUTAKI

S80 DHW tank, the heating coil of the tank is placed in a higher position than the indoor unit air purger. Then, to totally purge the space heating circuit, it is very important that the heating coil of the tank is fully air purged.

• lf the domestic cold water entry pressure is higher than the

equipment’s design pressure (6 bar), a pressure reducer must be tted with a nominal value of 7 bar.

• Ensure that the installation complies with applicable

legislation in terms of piping connection and materials, hygienic measures, testing and the possible required use of some specic components like thermostatic mixing valves, Differential pressure overow valve, etc.

• Make sure that all eld supplied components installed in the

piping circuit can withstand the water pressure and the water temperature range in which the unit can operate.

• Do not add any type of glycol to the water circuit.

4.1.4 Water lling



Heating coil circuit

Fill the DHW tank heating coil from the space heating circuit lling in point. Follow the instructions explained in the “4.1

Space heating and DHW” chapter to correctly perform the

operation.

! CAUTION

• Check that the heating coil pipes are correctly connected between

indoor unit and tank before lling the tank’s heating coil.

• Ensure the correct water quality of the indoor unit water circuit.



Domestic hot water tank and DHW circuit

1 Open the outlet water taps of the DHW installation one after

each other, to expel all the air from inside the water circuit.

2 Open the main DHW inlet valve in order to ll the tank. If

there is a shut-off valve installed in the DHW outlet, open it to allow circulation through the DHW installation.

3 When water begins to ow from the outlet water taps of the

DHW installation, close all these taps.

4 Finally, close the main DHW inlet valve when the pressure

reaches approximately 6 bars.

! CAUTION

• Check carefully for leaks in the water circuit, connections and circuit elements.

• Check that the water pressure in the circuit is lower than 7 bars.

• A pressure and temperature relief valve should be installed at the DHW inlet connection of the tank. If it is the case, manually operate its

relief valve to ensure that the water ows free through the discharge

pipe.

• Fill in the circuit with tap water. The water in the heating installation must comply with EN directive 98/83 EC. Non-sanitary controlled water is not recommended (for example, water from wells, rivers, lakes, etc.).

foot locknuts and when the tank is in the nal position (moving the

DHWT after levelling can make it uneven again).

• Start with all four feet screwed in as far as possible (factory supplied position).

• Use two or more people for levelling procedure.

Follow the process:

1 Loosen the locknut of the mounting feet which needs to be

extended (using a wrench).

2 Turn the mounting foot to extend the height (use the

hexagon or slot designed for this purpose in the shaft end).

3 When the mounting foot is in his end position, lock the

locknut. It may be necessary holding the foot to keep it from turning while tightening the locknut. Use for this purpose the hexagon or slot in the shaft end.

If it is needed to proceed with the levelling procedure with a second foot (process 1 to 3), never work over one foot at same time. When nish, all 4 locknut must be tightened rmly.

9 COMMISSIONING

When installation is complete, perform commissioning according to the following procedure and hand over the system to the customer. Perform the commissioning of the units methodically, and check that the electrical wiring and the piping are correctly connected.

? NOTE

Please, refer to YUTAKI S80 Indoor unit Installation and operation manual for the complete information of the commissioning.

9.1 PRELIMINARY CHECK

9.1.1 Checking the unit

• Check external appearance of the unit to look for any damage due to transportation or installation.

• Check that all the covers are totally closed.

• Check that there is respected the service space

recommended (see “3.2 Service space” in this document for the tank and the Outdoor and indoor unit Installation and

operation manuals).

• Check that the unit has been correctly installed and that the mounting foot are correctly adjusted.

9.1.2 Electrical checking

! CAUTION

Do not operate the system until all the check points have been cleared:

• DO NOT CONNECT THE POWER SUPPLY TO THE INDOOR UNIT AND DHW TANK PRIOR TO FILLING BOTH CIRCUITS WITH WATER AND CHECKING WATER PRESSURE AND THE TOTAL ABSENCE OF ANY WATER LEAKAGE.

• Do not touch any electrical components before than three minutes after turning OFF the main switch

• Check to ensure the electrical wiring of the DHW tank and the indoor unit are connected as shown in the corresponding chapter.

• Check to ensure the external wiring is correctly xed to avoid problems with vibrations, noises and cut out wires with the plates.

9.1.3 Hydraulic circuit checking

• Check that the circuit and the tank have been properly ushed and lled with water and that the installation has been drained: the pressure of the heating coil circuit must be

1.8 bar (at least 1.5 bar).

• The pressure of the DHW circuit in the tank has to be lower than 7 bars.

• Check that the water tank heating coil is completely lled.

• Check for any leakage in water cycle. Pay special attention

to the water piping connections.

• Make sure the system’s internal water volume is correct.

• Make sure the DHW tank internal water volume is correct.

• Check that the hydraulic circuit’s valves are fully open.
