3. OPERATION AND SERVICE3.1 Start-upThe hydronic back-up boiler (see Figure 5) and solar storagetank (see Figures 4 & 5), constitute a functional unit. Hot water isgenerated throughout the year by the solar collectors (see Figure 4).Supplemental heat is provided by the back-up boiler when there isinsufficient solar energy available (see Figure 5).The entire heater and hot water system must be filled with waterand have adaquate air ventilation. Please refer to the solarcollector’s and the boiler’s installation instructions.4. MAINTENANCE AND CLEANINGRoutine care and maintenance extends the life expectancy andoperating safety of the hot water storage unit. The outer casingshould be cleaned with a slightly damp cloth and commerciallyavailable neutral cleaning agent. This should be done on a regularbasis.4.1 Temperature / Pressure Relief Valve4.3 Replacement of the Sacrificial AnodeDepending on the composition of the tap water, an inspectionof the sacrificial anode (Pos. 1, Figure 1) at timely intervals isrecommended. With heavy wear, an original equipment replacementanode must be installed to protect the inner container fromcorrosion. An inspection should be performed at least once a year.WARNING: THE T&P RELIEF VALVE IS DESIGNED TO RELIEVE BUILTUP PRESSURE IN THE WATER HEATER. FLUID MAY BE DISCHARGEDAT HIGH TEMPERATURE AND/OR PRESSURE. SCALDING HOT WATERINJURIES CAN OCCUR.NOTICE: THE WATER HEATER AND T&P RELIEF VALVE SHOULD BEINSTALLED AND PIPED IN AND TO AN AREA WHERE WATER DISCHARGEAND LEAKING WILL NOT CAUSE PROPERTY DAMAGE.The proper function of the Temperature / Pressure (“T&P”) reliefvalve is required to prevent damage to the hot water storage unit.The T&P valve needs to be open during cold-water addition. Thewater has to flow from the relief line at full stream.4.2 DecalcificationWith hard tap water, a deposit of scale will form on the inside ofthe storage unit. Based on professional experience, it is necessaryto decalcify with commercially available solvents at timely intervals.Follow the manufacturers instructions for solvent use. The hot waterstorage unit needs to be emptied. The inspection cover must beremoved and sediments on the tank bottom must be flushed.4 | SBB S & SBB PLUS SOLAR STORAGE TANKS WWW.STIEBEL-ELTRON-USA.COM
5. FAILURES – CAUSES – CORRECTIONENGLISHFailures Causes CorrectionInadequate water pressureShut-off valve is not completely open.Open Shut-off valve. Clean or exchange pipes.Cold or hot water line is obstructed.Hot water flow inadequateBoiler temperature is set too low.Recommended 176 to 185 °F / 80 to 85 °C.Heat exchanger is calcified.Set boiler to recommended temperature.Clean heat exchanger.Hot water storage tank not being heatedProgram selection at the heater control is notSelect and set program per instructions.properly selected.Outlet quantity inadequate Aerator at the extraction point blocked. Unscrew aerator and clean.Hot water supply exhausted too quicklyFlow rate too high. Recommended 2.6-3.9 gal./min.or 9.8-14.8 l/min.Restrict spigot valve rate.6.
