TR2000TF – 6 720 875 992 (2021/08)

The water is heated to the temperature set on the temperature selector

switch 1. When the selected temperature has been reached, the peak-

rate heating automatically switches off.

• Set a higher temperature with the temperature selector switch 1 if

you frequently need to reheat water during the peak period.

As a result, you will have a larger volume of mixed water.

• Rotate the temperature selector switch 1 to position “•” if the floor-

standing water heater will not be heated for a prolonged period.

This setting protects the appliance from freezing.

This does not apply to the fittings and pipes in the cold-water inlet!

4.5 Checking the safety valve

During the heating process, expansion water must drip out of the safety

valve outlet 3.

For reasons of safety the outlet must not be blocked.

•Check that the safety valve is functioning properly at least once

a month.

• Rotate ventilation screw 4 until the valve opens and a powerful jet of

water comes out of the outlet 3.

• Close the valve again with the ventilation screw.

• If the safety valve does not function as described, rotate the

temperature selector switch to position “•” and contact a qualiﬁed

professional.

4.6 Saving energy

The appliance operates particularly economically at low temperatures.

Therefore, only set the temperature which you require.

The floor-standing water heater operates most economically in position

“E” (approx. 60 °C), even when large amounts of hot-water are required.

At higher water temperatures, the appliance calcifies at an increased

rate, resulting in greater heat losses!

4.7 Decalcifying

• Inspect the fittings regularly for lime scale deposits and descale with

commercially available descaling agents.

• Actuate the safety valve regularly to remove the lime scale (see

“Checking the safety valve”).

The level of lime scale deposited from the water is increased or reduced

at higher temperatures depending on the local water quality (hardness

level I/II/III; soft, medium or hard). It is deposited on the interior of the

water tank and on the heating element as boiler scale and influences the

performance leading to longer heating up time and service life of the

appliance.

The appliance must therefore be checked and decalcified regularly by

a qualiﬁed professional. Check also the taps/valves regularly. You can

remove limescale deposits at the tap outlets using commercially

available descaling agents.

Please schedule your first and/or next maintenance visit (inspection of

the protection anode and descaling) with your qualified specialist.

Maintenance work may only be carried out by a qualiﬁed

professional. Improper repairs may put the user in extreme danger.

Never use abrasive or corrosive cleaning agents during heating element

or tank interior cleaning.

4.8 Cleaning

• Simply wipe the appliance with a damp cloth. Do not use acidic or

abrasive cleaning materials.

4.9 Customer Service

• In the event of a malfunction, unplug the appliance from the power

supply (pull out the fuse or activate the circuit breaker) and contact

customer service.

Details can be obtained from a customer service centre regarding your

nearest customer service centre or authorised repair shop.

• We ask you to always provide the BOSCH serial number (SNR/TTNR)

of your appliance when calling in a customer service engineer.

5 Maintenance instructions

CAUTION:

▶Maintenance work must only be carried out by a qualiﬁed

professional, pursuant to VD E0700 or local regulations.

•The appliance must be isolated from the power supply in all poles.

5.1 Decalcifying

Do not use a decalcifying pump. This would decalcify the heating flange

but would damage the protective anode and the interior wall of the tank.

Procedure:

• Disconnect the floor-standing water heater from the power supply.

• Remove the switchroom cap.

• Disconnect the heating flange and remove.

• Decalcify the heating flange.

• Remove loose pieces of lime from the floor-standing water heater.

• Fit the heating flange and connect in accordance with the circuit

diagram.

• Fit the switchroom cap.

5.2 Checking the protective anode

The protective anode must be removed prior to checking and must be

checked after the first two years of use and replaced if necessary.

It is situated next to the hot-water outlet nozzle and is covered by the

thermal insulation (recognizable by a protrusion).

• Unzip the protective jacket. Cut out the thermal insulation with

aknife.

• Screw out the protective anode and check.

If the protective anode is used up, it must be replaced with a new one.

If there is insufficient space to install a pole anode, install a chain anode.

The protective anode must have a good metallic conduction with the

floor-standing water heater. Cover the screwed connection of the anode

with the piece of thermal insulation material which was previously cut

out.

• Zip up the protective jacket.

Note: The protective anode, located in the floor-standing water heater,

must be checked for the first time after two years and replaced if

necessary. The qualiﬁed professional is familiar with the local water

quality and will specify when the next maintenance check should be

carried out.

5.2.1 Safety valve

• Vent the safety valve until the full water jet is flowing out.

• Close the safety valve after carrying out the check.

The thermostat and thermal cut-out are located together in the heating

flange. If the thermal cutout disconnects the appliance due to

a malfunction, the whole unit must always be replaced. The cause of the

malfunction must be eliminated by a qualiﬁed professional.
