ENG INSTALLATION INSTRUCTIONS, COMMISSIONING AND MAINTENANCE
What follows is determinant for the warranty validity.
1. The installation and commissioning must:
•
Be executed by a qualified installer.
•
Be provided, where necessary, with a pressure water reducing in entrance.
•
Be provided with a safety valve according to the technical datas of the boiler.
•
Provide expansion vessels connected at a maximum distance of one meter from the tank (see the measuring
board of the expansion vessel) proportioned to the boiler's dimensions (the size shall be checked by an expert).
•
Provide washing of the lines before commissioning, any impurities or processing chips present in the hydraulic
system can cause corrosion and permanently contaminate the tank.
•
Be provided with filters upstream of the tank to avoid the deposit of heavy particles or processing residues
inside the tank.
2. Before starting, check the hydraulic seal of the connections and hatches. Apply a torque of 20 Nm for handhole
hatches and 40 Nm for manhole to the hatch screws. If some leakage occurs check the assembly of the expansion
vessels.
3. Install the boiler in a technical room providing suitable drainage in case of possible liquid leaks from the tank.
4. Do not switch on any heat source connected to the tank until it is guaranteed to fill it completely.
5. In case of use on the system of materials other than those of the tank, provide for the dielectrical insulation of the
different parts. The equipotential ground connection must be made both for the tank and for the pipes connected
to it and must be suitably checked in compliance with the regulations in force.
6. Make sure and arrange that, for the purpose of preventing contamination of the domestic water and altering the
anti-freezing mixture of the solar circuits, the pressure of the exchanger is always lower than the pressure of the
accumulation, also through automatic control of the differential pressure between the circuits primary and
secondary.
7. In case of danger of freezing, the tank and the exchanger must be heated or completely emptied. Even if the tank
is not used for a long time, empty the tank, in fact the prolonged stagnation of water in the tank favors internal
corrosion and the proliferation of bacteria and microorganisms.
8. The temperature of the boiler inside must always be under 95°C (70°/80°C for the SMALVER/SMALTECH models).
9. In order to avoid corrosion, the anodes must be inspected after each 12 months. However, where the water is
particularly aggressive, the inspections must be done each 6 months; if the anode diameter in any section is less
than 22 mm, it must be replaced, if covered with limestone is to be cleaned.
10. The water Langelier Index at the operating temperature, must range from "0" to "+0,4", hardness within 10°F and
20°F, maximum concentration of chlorides 70 mg/l, minimum conductivity 150 microS/cm.
