Appliance description

The heat from the heat pump‘s heating water is transferred to the DHW by the smooth-tube indirect coil. The internal steel cylinder is coated in “anticor®” enamel and is equipped with a thermometer and a signal anode. The anode with a consumption indicator protects the internal cylinder from corrosion.
SBB 401 WP SOL (AU) | SBB 501 WP SOL (AU)
These appliances are also equipped with a second indirect coil for DHW heating with solar energy

Cleaning, care, and maintenance

• Have the function of the safety assembly and electrical safety of the fitted accessories regularly checked by a qualified contractor.
•  Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

The signal anode consumption indicator

Material losses
If the consumption indicator changes color from white to red, have the signal anode checked by a heating contractor and if necessary replaced.

1. Signal anode consumption indicator
2. white = anode OK
3. Red = check by heating contractor required

Scaling

• Almost every type of water deposits limescale at high temperatures. This settles inside the appliance and affects both the performance and service life. If a flanged immersion heater is installed, the heating elements must be descaled from time to time. A heating contractor who knows the local water quality will tell you when the next service is due.
• Check the taps/valves regularly. You can remove limescale deposits at the tap outlets using commercially available descaling agents.

Troubleshooting

Telephone your contractor.
To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-000000):

• Corrugated connection pipe with union nut and threaded end for optional linking of the lower and upper indirect coils:

WRV 32 (part number 232628)
SBB WP (AU) | SBB WP SOL (AU) must only be connected to specified heat pumps and solar pump assemblies. (see chapter “Specification / Heat sources”.

Preparations

Installation site
Always install the appliance in a room free from the risk of frost and near the draw-off point. Ensure the floor offers sufficient stability (see chapter “Specification / Data table” for weight).

• Use the adjustable feet to compensate for any unevenness in the floor.

Minimum clearances

• Maintain the minimum clearances.

Transport

Material losses
We recommend removing the cylinder casing for transportation to the installation location to prevent it from becoming dirty or damaged.

SBB 501 WP SOL (AU)

• Both side insulation sections can be removed for transportation in tight spaces. To do this, remove the cylinder casing.
• Use the fixing straps to refit the thermal insulation sections after transportation.

Side thermal insulation section

• Ensure that the closures are in the joint between a side thermal insulation section and the thermal insulation of the cylinder.

Preparing for installation

Removing/fitting the cylinder casing

Note
Open or remove the cylinder casing before fitting the high limit safety cut- out and DHW circulation/indirect coil lines. Fit the cylinder casing before fitting a flanged immersion heater. The plinth trim should be fitted after the tightness check.

Checking the signal anode
Material losses
The appliance must not be operated without a consumption indicator or with a damaged one, otherwise water will leak out once the anode is depleted.

Heating installation
The connected heat source must not exceed a maximum flow temperature of 60 °C or must, alternatively, be equipped with a high limit safety cut-out. You may also install a motorised valve that interrupts the cylinder heating by the heat source.

• Flush the indirect coils with water before connecting the heating water pipes.

Water quality, solar circuit
A glycol/water mixture of up to 60 % is permitted for the indirect coil in the solar circuit if only dezincification-resistant metals, glycol-resistant gaskets and diaphragm expansion vessels suitable for glycol are used throughout the installation.

Oxygen diffusion

Material losses
Avoid open heating systems and plastic pipes in underfloor heating systems which are permeable to oxygen.

In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen diffusion may lead to corrosion on the steel components of the heating system (e.g. on the indirect coil of the DHW cylinder, on buffer cylinders, steel heating elements or steel pipes).

Material losses
The products of corrosion (e.g. rusty sludge) can settle in the heating system components and can result in a lower output or fault shutdowns due to reduced cross-sections.
Solar installation
The circuit must include an air-vent, a check valve and an expansion vessel. The check valve is not required if you are utilising a Solar compact installation.

• Flush the solar indirect coil with water before connecting the solar circuit.

SBB 401 WP SOL (AU) | SBB 501 WP SOL (AU) without solar installation

• Connect both indirect coils to the “heat pump heating return” and “solar flow” connections (see chapter “Specification / Dimensions and connections”).

Fitting the water connection and the safety assembly

Note
Carry out all water connection and installation work in accordance with regulations.

• Flush the line thoroughly.
  The max. permissible pressure must not be exceeded (see chapter “Specification / Data table”).

• Install a type-tested safety valve in the cold water supply line. Please note that, depending on the static pressure, you may also need a pressure reducing valve.

1. Cold water connection
2. Cold water inlet pipe
   • Connect the cold water supply directly to the cylinder or with the connecting pipe routed between the cylinder feet.
   • During fitting, counterhold the fitting with an open-ended spanner (size 36).
   • Check the rigidity of the connecting pipe and secure it further if required. See chapter “Specification / Hydraulic diagram” for general arrangement in schematic form. You can fit the safety assembly in various positions to suit the space available but it must be placed in the same order as shown. The safety assembly provided in the pack is fitted to the cold water supply with the exception of the T&P valve which is fitted at the top of the DHW cylinder. DHW cylinder relief valve connections should not be used for other purpose. No valve should be fitted between the expansion valve and the DHW cylinder.
   • To obtain a balanced water pressure in the cold water and DHW lines, position the cold water outlet directly on the outlet side of the pressure reducing valve.
   • The expansion valve should not respond under normal operating conditions as the expansion vessel will accommodate the water as it expands during the heating process.
   • If a secondary return circuit is used then an additional expansion vessel may be required.
   • Run the expansion valve outlet and that of the T&P valve to a drain via a tundish. The purpose of the tundish is to let water be seen should these valves respond. The outlet pipe should not exceed 9 metres in length without forming an air break, i.e. tundish. The pipe must fall continuously throughout its length with no additional 90° bends. It must be heat resistant and discharge to a safe visible position away from any electrical devices. The pipe diameter must not be smaller than the valve outlet. The two discharge pipes can be joined together at the point of discharge into a single tundish if required.
   • Size the drain so that water can drain off unimpeded when the safety valve is fully opened. The blow-off aperture of the safety valve must remain open towards the atmosphere.
   • Fit the blow-off line of the safety assembly with a constant slope.
   • Observe the information in the installation instructions of the safety assembly.

Fitting the thermometer and DHW sensor

1. Thermometer
   • Insert the thermometer as far as it will go and align it.
   • Insert the DHW sensor into the upper “Sensor heat pump DHW” sensor well (recommended position for energy saving). For higher levels of DHW convenience, you can alternatively insert the DHW sensor into the lower “Sensor heat pump DHW optional” sensor well (higher energy demand).

Commissioning

Note
Some fluxes used to solder pipes and fittings need to be flushed out with hot water. Where this is the case the cylinder should be heated to its normal operating temperature and all pipe work flushed with hot water to ensure all flux and debris is removed from the system.

DHW system

• Open all taps.
• Open the shut-off valve in the cold water feed line. Allow the system to fill and flush out all flux and debris from the installation.
• Close all taps.
• Open a downstream draw-off point until the appliance has filled up and the pipes are free of air.
• Check the function of the fitted accessories.
• Check that the DHW temperature on the heat pump control unit is displayed correctly.

Heating system

• Observe the operating and installation instructions of the heat pump.
• Vent the indirect coils after filling the heat pump system.

Solar system

• Observe the operating and installation instructions of the solar pump assembly.
• Vent the indirect coils after filling the solar system.

Appliance handover

• Explain the appliance function to users and familiarise them with its operation.
• Make users aware of potential dangers, especially the risk of scalding.
• Hand over these instructions.

Shutting down

• Disconnect the appliance from the mains at the MCB/fuse in the fuse box.
• Drain the appliance. See chapter “Maintenance / Draining the appliance”.

Troubleshooting

Maintenance

WARNING Electrocution

• Regularly vent the expansion valve on the safety assembly until a full water jet is discharged.
• Close the expansion valve when the check is complete.
• Check the T&P valve for tightness.

Draining the appliance
WARNING Burns
Hot water may escape during the draining process

If the cylinder needs to be drained for maintenance or to protect the whole installation when there is a risk of frost, proceed as follows:

• Close the shut-off valve in the cold water line.
• Open the hot water taps on all draw-off points.
• Drain the appliance via the drain valve of the safety assembly

Replacing the signal anode

• Replace the signal anode if it becomes depleted. Ensure there is a good connection between the anode and the cylinder (maximum permissible transition resistance 0.3 Ω).

Cleaning and descaling the appliance
You can use the flange aperture as an inspection port to view the cylinder interior.

1. Threaded extraction holes
   • Use the threaded lift-off holes to release the flange plate from the flange connector
