1. WATER
Check that the physical-chemical characteristics of water are within the values shown into EC directive 80/778.
As far as Italy is concerned, also refer to both DPR 24-05-1988 n.236 as amended and integrated (at present, the Ministerial Decree issued by the Ministry of Health on 14/07/1988 and the Ministerial Decree issued by the Ministry of Health on 14/02/1989 as well are in force) and DM26/03/1991.
Make use of treatment systems that are suitable to keep the potable water characteristics as above specified and being in compliance with what provided for by the Authorities in charge.
2. CORROSION PROTECTION
2.1. VITROFLEX HI-TECH
Cylinders’ surface of series 209 SPTE has been treated with the anticorrosive VITROFLEX HI-TECH, which is waterproof, dielectric, highly thermal shock-resistant and collision proof ; furthermore, it can ensure the best alimentary-sanitary characteristics. VITROFLEX HI-TECH, in fact, makes SICC cylinders suitable for the potable water supply, in accordance with EEC directive 89/109.
2.2. Magnesium anode
Cylinders 209 SPTE have an internal corrosion protection consisting of a fully active system given by magnesium anodes. Its wear status must be periodically checked each 6 months, at least, by pressing the proper tester key and being sure that the indicator position stays within the green zone of the reading field, otherwise the anode replacement should be arranged as soon as possible.
3. PRODUCT CHARACTERISTICS
Series 209 SPTE products deal with cylinders created to produce hot sanitary water. They have been manufactured both in the vertical and horizontal versions and they are particularly suitable for plants of small and medium sizes. They are equipped with brackets for the wall fastening as well as threaded couplings for the feeding hydraulic connections. They mainly consist of a tanker, an exchanger and an insulation.
3.1. Storage
Tankers have been manufactured with high quality carbon steel plates. Their relevant arc welding deals with a totally automatic procedure, which has been approved by the main testing entities. Max. operation pressure allowed is of 8 bar and max. temperature allowed is of 99 °C. Series 209 SPTE’s tanker has been internally treated with VITROFLEXHI-TECH anti corrosive, so that it can hold water for alimentary-sanitary purposes, in accordance with EEC directive 89/109.
3.2. Heat Exchanger.
The heat exchanger consists of a pigtail coil. 12 bar is its max. operation pressure, whilst 99 °C is its max. temperature.
3.3. Insulation
Insulation concerning series 209 SPTE consists of a hard – high density polyurethane insulation lined with a pre-coated lamination, allowing to limit leakage according to the values shown as follows:
Type heat leakage (at + 40 °C between tanker and environment) KW/h 80 0.064 100 0.074 150 0.077 200 0.090 300 0.110
3.4. Electric kit.
Cylinders 209 SPTE may be equipped with an optional electric kit, which consists of:
- Winter-summer switch (pump / element)
- Timer
- Manually rechargeable safety thermostat - 220 Volt 2000 watt monophase electric element.
4. INSTALLATION, USE AND MAINTENANCE
4.1. Installation
Always arrange for safety valves and expansion tanks for the primary and secondary circuits. During the installation phase, always comply with the laws in force and the drawings attached. The appliance shall always be equipped with a cathode protection (magnesium anode). Always arrange for an automatic air discharge valve to be placed on the cylinder upper side, by the hot water outlet line. Make use of dielectric couplings when cylinder is connected to tubes which are made of another material. Charge and raise steam the primary circuit before the sanitary water tank. See the thermostat wiring diagram as for the electric connections (series 209 SPTE).
To fit the electric element proceed as follows: - remove the relevant coupling plug (1 ¼”); - assembly the element;
- then connect it and arrange for a safety series manual charge thermostat, as to the thermostat, to avoid boiling.
4.2. Use
The cylinder has been manufactured to produce hot water only; therefore, any other different use shall be considered as dangerous and unsuitable.
The cylinder should be used in accordance with the temperature and pressure limits shown on the nameplate and within such booklet as well.
Check the magnesium anode at least 2 times a year and during the boiler normal use; such checks should be more frequent in case water is particularly aggressive.
4.3. Maintenance
Magnesium anode replacement
Discharge the cylinder, remove the anode tester cable, then unscrew the anode plug, by means of a 40mm socket spanner, and put a vessel for the water of the tanker lower part under the same plug. Make use of original anodes and gaskets to replace the old ones. Then, fill the boiler again and make sure that there is no leakage.

! Warning !
Always disconnect the power supply before any
kind of operation (assembly, maintenance, technical
repair, etc.) !

10. TROUBLESHOOTING
Problem Cause Solution
1 Water leakage from the
anode. No internal seal. Fit the seal by disassembling the anode.
No circulation due to a lock of the pump or valve serving the primary circuit.
Unlock or check the pump/valve after being sure that they are power supplied.
Too much air into the primary circuit. Vent and install an automatic air valve if there is
not any. 2 No or poor sanitary hot
water production.
Limestone encrusted exchanger Clean the heat exchanger.
3 Too much pressure increase
within the primary circuit. Likely hole into the heat exchanger.
Check the leakage by disassembling the primary circuit and pressurising the secondary circuit, by closing both secondary circuit inlet and outlet, inserting a pressure gauge to check the pressure change. Change the heat exchanger.
Too much pressure of the supply network Install a pressure reduction filter.
No expansion tank or insufficient expansion tank temporary pressure.
In case the pressure increase coincides with the temperature increase, it is important to check if there is an expansion tank and its temporary pressure as well.
4 Too much pressure increase
within the secondary circuit.
No safety valve.
The cylinder pressure must never be higher than what provided for by its nameplate. A properly calibrated safety valve is always needed and required.
Check that the sensor (bulb) has been correctly installed and that it properly operates.
5 The primary circuit valve or pump do not start up.
Thermostat bulb has not been installed or it
does not work. Check by means of tester the thermostat contact closing when the water temperature is lower than the setup value. In case the contact does not close, replace the thermostat.
Excessive stray currents.
Ground the appliance. Make use of dielectric joints. Ground the surrounding electric appliances.
6 Anode fast wear.
Excessive free surface to be protected, due to
