Important Tip

Stiebel Eltron hot water heaters should only be installed or serviced by licensed installers. These are not do-it-yourself appliances.

Please hand this Operation and Installation Manual and hand over to the home or building owner when the installation is complete.

Operating Instructions for the User and the Technician

1. Operation and Service

1.1 Start-up

The boiler (39) and solar storage tank (30) after installation, constitute a functional unit (refer Diag. 4 and 5). Hot water is generated throughout the year by the solar collectors.

The entire heater and hot water system must be filled with water and have good air ventilation. Please, refer to the solar collector’s and the boiler’s installation instructions.

2. Maintenance and Cleaning

Routine care and maintenance extends the life expectancy and operating safety of the hot water storage unit. The outer casing should be cleaned with a slightly damp cloth and commercially available neutral cleaning agent, this should be done on a regular basis

2.1 Membrane Safety Valve

The proper function of the safety group (28), especially of the membrane safety valve (21) is very important to prevent damage to the hot water storage unit. The membrane safety valve needs to be monitored for functionality during coldwater addition (27). The water has to flow from the drip line at full stream.

The discharging water can be hot!

2.2 Decalcification

With hard tap water, a deposit of scale will form on the inside of the storage unit. Based on professional experience, it is necessary to decalcify with commercially available solvents at timely intervals. Follow the manufacturers instructions for solvent use. The hot water storage unit needs to be emptied. The revisions flange at the storage bin must be dismantled and sediments on the tank bottom must be removed.

2.3 Exchange of the Safety Anode

Depending on the composition of the tap water, an inspection of the safety anode (Pos. 1, Diag. 1) at more or less timely intervals is recommended. With heavy wear, an original equipment replacement anode (refer Ch.6.8 and Ch.7 ) must be installed to protect the inner container from corrosion. An inspection should be performed at least once a year.

3. Failures – Causes – Correction

Failures

Causes

Correction

Inadequate water pressure

Shut-off valve is not completely open. Cold or hot water line is obstructed.

Open Shut-off valve. Clean or exchange pipes. Hot water flow inadequate

Boiler temperature gauge is set too low. Recommended 80-85°C. Heat exchanger is calcified.

Set boiler temperature gage to recommended temperature. Clean heat exchanger.

Hot water storage tank not being heated

Program selection at the heater gage is not properly selected.

Select and set program per instructions.

Outlet quantity inadequate

Perlator at the extraction point blocked.

Unscrew perlator and clean. Hot water supply too fast exhausted

6. Set-up and Installation

6.1 Set-up

Inspect the packaging for damage and remove packaging preferable only at the installation site.

For the selection of the installation site, the tare weight of the storage unit (unit and insulator) including the fill-water weight must be considered. The room has to be above freezing. For drainage, the water drainage pipe must be freeze proof.

6.2 Connection

Refer to Diag.1 and Diag. 2.

6.3 Heater Installation

The installation of the heating circuitry is shown in Diag. 4. The heater installation can be according to the installation diagram. This, however, varies according to operation. In addition, it must be assured that no air can collect in the system. Therefore, an exhaust unit has to be built into the heating circuitry (31).

6.4 Hot Water Installation

6.4.1 Prior to installation check that the local conditions are compatible with the appliance design, especially that the maximum working excess pressure of 145 PSI (10 bar.) can be maintained.

6.4.2 A steel or a copper pipe with insulation can be used for the hot water connectors. Copper pipe with insulation is especially suitable because of its low friction and heat loss.

Required combination

Cold water pipeline Hot water pipeline

Copper pipe copper pipe Steel pipe steel or copper pipe Plastic steel or copper pipe

6.4.3 A safety group (28) must be installed into the cold water supply (27, Diag. 4). The order of the individual fittings must be in accordance to local regulations.

6.4.4 The membrane safety valve (21) has to be set to 145 PSI (10 bar.) excess pressure and sealed. It can only be installed into the cold water supply (27). The supply has to be thoroughly inspected prior to installation. Installation of dirt filters or any other narrowing of the supply line to the membrane safety valve is forbidden.

The membrane safety valve (21) has to be easily accessible. Expansion water generated during the heating has to flow visibly into a funnel and be drained. Funnel and drainage pipe must be large enough to accommodate water drainage with a fully opened membrane safety valve. The drainage pipe must be protected from freezing and must not lead outdoors.

The membrane safety valve (21) has to be set such that there are no water drips with the resting heater (storage water being reheated).

Heavy dripping of the membrane safety valve on the outside of the warming operation can be caused by dirt in the valve seat of water pressure that is too high. At excessive water pressure a pressure reducer (25) needs to be installed.

6.4.5 During installation all necessary screws outside of the flange area must be in order. This assures that the revision flange can be maintained.

6.4.6 Drainage of the hot water tank (30) is via the drainage faucet (29) at the drainage connector.

6.4.7 The circulator can be attached to a separate socket across the thermometer. Drill the outer casing with a hole saw ∅ 50 where marked and remove insulation from the socket in that area.

For energy conservation, use of a circulator is not recommended.

6.5 Hot water temperature probe

6.5.1 The hot water temperature probe is to be installed into the immersions sleeve (Pos. 3 Diag.1) of the hot water storage tank. Then the connector pipe for heater regulation has to be installed and attached to the clamps of the low voltage plug as described in separate operation and installation instructions for the regulator.

6.6 Solar Storage Tank – Temperature Probe

The solar storage tank temperature probe must be attached to the immersion sleeve of the hot water storage tank (Pos. 6 Diag. 1). The temperature probe must be inserted into the probe sleeve until its dead stop (Ill.6). The compressed flat rod has to be inserted until set with the spring struts in the front. Then the connector pipe has to be laid according to solar regulator SOM 6K, SOM 6/3D or SOM 7/2 and attached to the clamps of the low voltage plug as described in separate operation and installation instructions of the regulator.

Diag. 6 Diag. 7

6.7 Connection to the Solar Unit

The installation of the solar circuitry is shown in Diag. 5, page 12. The solar circuitry installation can follow the installation diagram. This differs depending on the application.

Refer to the separate operation and installation instructions for the solar collector SOL 25 S.

Test operation after installation. Start up must follow the approval of the installer (refer operation and use).

6.8 Signal anode (spare part)

If a signal anode is installed into the SBB … K SOL storage tank, the following installation of the signal anode must be observed:

Installation – signal anode

• Pull out the red shut-off plug while simultaneously depressing the pressure ring, Diag. 6a. on page 13.

• Push in the open pipe end of the indicator element until dead-stop, Diag. 6b.

• Attach the sticker “Note Signal Anode” to a highly visible spot on the insulation.

When the storage tank is not operated with a signal display, the red plug must remain in the anode!

Function – Signal Anode

(Safety Anode with usage display)

• After consumption of the anode, humidity escapes through the hollow anode core to the signal cartridge and causes a color change there (refer Diag. 7)

• When the cartridge turns red contact the installer so he can check the anode and if needed replace it.

Page 9

6.9 Screw-in unit BGC

BGC is screwed into a 1 “ bushing into the front side of the storage tank. This is then locked with a 4-corner plug SW22. As an alternative the bushing can be dismantled with a 12-corner nut SW26. The installation instructions of the screw-in heater must be observed.

7. Tips for the User

Routine maintenance improves operating safety and life expectancy of the solar hot water storage tank SBB … K SOL.
