GENERAL PRECAUTIONS

GENERAL WARNINGS

All products are protected with suitable transport packaging.

The material must be stored in dry environments and protected against weathering. This instruction manual provides technical information for installing the kit. As for the other issues related to kit installation (e.g. safety in the work site, environment protection, injury prevention), it is necessary to comply with the provisions specified in the regulations in force and principles of good practice.

Improper installation or assembly of the appliance and/or components, accessories, kit and devices can cause unexpected problems to people, animals and objects. Read the instructions provided with the product carefully to ensure a proper installation. Installation and maintenance must be performed in compliance with the regulations in force, according to the manufacturer’s instructions and by authorised professionally qualified staff, intending staff with specific technical skills in the plant sector, as envisioned by the Law.

INSTALLATION

Proceed as follows to assemble the kit (Fig. 1):

• Remove voltage from the appliance by disconnecting the switch upstream from the boiler.
• Empty the domestic hot water circuit by opening any domestic hot water system cock in order to allow air to enter the boiler, making sure that the relative cold water inlet cock on the boiler has been closed (see boiler instruction book).
• Disassemble the casing (see boiler instruction book).
• Eliminate the two cold water inlet and hot water outlet pipes present in the boiler.
• Mount the boiler valve using the upper pipes (1 straight pipe and 1 bent pipe), interposing the relative gaskets. Use two bent pipes in the case of the Victrix Mini kW boiler.
• Premounting the flexible pipes (operation to be repeated for all 3 flexible pipes):
  • insert the red plastic cap into the mouth of the pipe;
  • in sequence insert the brass ring positioning it on the 3rd groove and the two o-rings, positioning them on the 1st and 2nd groove (see exploded detail fig. 1);
  • eliminate the red plastic cap.
• Make the hydraulic connections to the valve using the flexible pipes, adapting them to requirements and interposing the relative gaskets.
• Now connect the flexible pipes to the system, using a fitting present in the kit for connection to the hot water coming from the solar panels and via the fittings present in the boiler blister for connection of domestic hot and cold water.
• Once the tightness of the hydraulic circuit has been verified, re-mount the casing, open the cold water inlet cock and re-apply voltage to the boiler to take it back to normal functioning conditions.

USING THE SOLAR VALVE

• The solar valve mixes the hot water coming from the solar system on the basis of the temperature to be obtained (see functional layout, fig. 2).
• Turn the knob in a clockwise direction to decrease the temperature and in an anti-clockwise direction to increase it.
• When the water entering the solar valve (HW solar panels) is over 48 °C +/- 1 °C the valve diverts the flow of water to the mixer section.
• On output (Domestic HW) there will be water at the temperature set using the knob situated in the lower part (however the temperature of the water will be at maximum the same as the temperature of the cylinder).
• If the water at the solar valve inlet is at a temperature below equal to 48 °C +/- 1 °C the valve diverts the flow to the boiler (Boiler CW) which heats the water to the temperature set by the boiler itself (see boiler instruction book). The water at boiler outlet is however mixed by the valve according to the value selected on the knob.
• The larger the number set on the valve the greater will be the outlet temperature.
• The knob has a safety block to prevent having excessively hot water at outlet (Domestic HW) positioned at 4. To exceed this value, press the button and turn the knob anti-clockwise.
• For excellent functioning it is advised to position the solar valve on the first notch after number 4 (corresponding to the first notch after the safety block, value of about 45°C) and to set the boiler with domestic hot water outlet between 45 – 50 °C.
• The boiler can function with the DHW thermostat set as “fixed” or “correlated”. It is recommended to maintain it as “correlated”. However, in certain conditions, the boiler may ignite or switch-off too frequently. In these cases set the “DHW thermostat” function according to requirements.
