5.5.1 Series connection of the lower and upper coils
Attach the upper connection on the lower coil to the lower
connection on the upper coil in the DHW tank.
Attach the tank charging pump to the upper connection on the upper
coil.
Attach the lower connection on the lower coil to the return piping on
the boiler.
Install the Aquastat or DHW temperature sensor in the sensor well
provided for this purpose ( Fig. 2, page 5, [3]).
5.5.2 Parallel connection of the lower and upper coils
We recommend attaching each coil in the DHW tank to its own tank
charging pump.
6 Commissioning
6.1 Commissioning the DHW tank
Have the installer of the heating system or a qualified contractor
commission the equipment.
Commission the boiler and other accessories in accordance with the
manufacturer's instructions in the corresponding installation and
operating manuals.
To bleed air from the DHW tank, open the highest tap/valve.
To fill the DHW tank, open the shut-off valve for the cold water inlet.
Flush the tank and piping thoroughly prior to commissioning.
Before heating up, check whether the boiler, tank and piping are
filled with water. Open the air bleeder valve for this purpose.
Check all connections, piping and the inspection port for leaks.
7 Shutdown
7.1 Shutting down the DHW tank
Switch off the temperature controller at the control panel, shut of the
heating system emergency shutoff switch, or disengage the heating
system circuit breaker.
Close the cold water inlet shutoff valve.
Drain the DHW tank via the drain valve by opening the highest faucet.
Close the shut-off valves to and from the boiler.
Depressurize the coils.
Drain and blow out the coils.
To prevent corrosion, dry out the inner space and keep the
inspection port covers open.
7.2 Shutting down the heating system when there is a
risk of frost
Shut down the heating system and the DHW tank as shown in
chapter 7.1.
8 Environmental protection/disposal
Environmental protection is one of the fundamental company policies of
the Bosch Group. We regard quality of performance, economy and
environmental protection as equal objectives.
Environmental protection laws and regulations are strictly adhered to.
To protect the environment, we use the best possible technology and
materials taking into account economic points of view.
Packaging
For the packaging, we participate in the country-specific recycling
systems, which guarantee optimal recycling. All packaging materials
used are environmentally-friendly and recyclable.
Old appliances
Old appliances contain materials that should be recycled.
The relevant assemblies are easy to separate, and all plastics are
identified. This allows the various components to be sorted for
appropriate recycling or disposal.
9 Maintenance
Allow the DHW tank to cool down sufficiently before performing any
maintenance.
Remedy all faults immediately.
Use original spare parts only!
The tank must be inspected annually and maintained as required.
Check the T&P safety valve annually.
When the coils are connected in series, the pressure loss
across the two coils is cumulative. Pressure drop of
connecting pipe must be added. Ensure that the pump
used can handle the resulting pressure drop.
NOTICE: Risk of equipment damage from excess
pressure! Excess pressure can cause stress cracking in
the enamel.
Never close the temperature and pressure safety
valve blow-off line.
Use only drinking water to check the DHW tank for leaks.
On the hot water side, the test pressure must not exceed
145 psi (10 bar) gauge pressure.
CAUTION: Risk of tank damage!
Residual moisture can result in corrosion.
Thoroughly dry out the inside (e. g. by means of hot
air) and leave the cleanout cover open.
DANGER: Risk of scalding from hot water!
Let the DHW tank cool down sufficiently.
Drain the DHW tank completely, even the lower chamber
of the tank and the coil.
