2 Installation instructions

Install the appliance as shown in the illustrations. Observe the instructions in the text.

2.1 Installation

Unpacking/Removing the cover (Fig. 1)

• Unpack the appliance and check for transport damage. If any components are damaged, then do not connect the appliance.
• Check that your appliance contains all components included in the scope of delivery: appliance, installation set with supplementary sheets, installation instructions, operating instructions.
• Please dispose of the packaging and the old appliance in an environmentally-friendly manner.
• When removing the cover from the appliance, please note the following: The cover is fastened by a central closure behind the service flap.

Preparations for installation (Fig. 2)

Important: Only use the supplied installation set.

The supplied water connection nozzles must be installed!

• Shut off water supply. The electrical connection (connection cable) must be disconnected from the power supply. Unscrew the fuse or switch off the circuit breaker.
• Install the water connection nozzles according to the instructions on the supplementary sheet.
  The electrical connection cable can either be guided in at the top (X) or bottom (Y).
• The rear panel must lie against the cold water connection nozzle in the position provided for such [8].

Wall mounting (Fig. 3)

• The grommet must tightly surround the connection cable. If it is damaged during mounting, the openings must be provided with watertight sealing.
• The electrical supply terminal can be fitted at the top (X) or bottom (Y). The sheath of the connection cable must extend for at least 40mm into the appliance.
• The distance to the wall is variable. You can compensate for any unevenness of the wall's surface. With a distance to the wall of 8-16 mm, insert the spacer and install the extender [3.-5].
• The appliance must be mounted securely on the wall. If necessary, attach it at the lower adjustable screws [6].

Water connection (Fig. 4, 5)

Before connecting the water, guide the AquaStop connection pipe into the grommet (Fig. 5, [7]). The grommet must tightly surround the connection pipe.
Connect the water supply, then open the cold water supply.
- When tightening the connections, make sure that the AquaStop is positioned vertically.
Press the grip surfaces together and pull out the transport protection attachment to the right (Fig. 5, [10].)
The appliance must be vented. To do so, open the warm water tap fully and flush out the appliance thoroughly for 1 minute.

Electrical connection/Mounting (Fig. 6)

Limiting the outlet temperature to 53^ (Fig. 10).

(Only for the following appliances; TR 5000R and TR 7000R.)

WARNING:

Risk of electric shock!

How to move the temperature limiting switch,

Disconnect the power supply before opening the appliance.
Remove the cover.
Move the temperature limiting switch to the 53^ position ( Fig. 10).

Only for appliances with power selector switches:

• Set the power using the power selector switch before connecting the wires to the mains connection terminal: Nominal output power left, reduced output right [1.] and the set output marked on the ratings plate.
  Screw the wires tightly into the mains connection terminal [2].
  Switch on the safety limiter [3].
  Install the cover (4.-7.).

Installation note

• The installation of non plug-in ready appliances must be undertaken by the respective utility operator or by a qualified specialist company, who can also assist you when you are requesting the approval of the utility company for installation of the appliance.

Startup (Fig. 7)

The device is compliant to IEC 61000-3-12.

First start-up

Switch on the fuses
Setting the temperature.
- Initial rinsing: Open the warm water tap fully and allow water to flow for at least 1 minute. Only then (for safety reasons) will the appliance begin to heat.

Tip: Should the appliance not start because of a reduced flow-rate, remove the perlator, shower head or similar before start and repeat the process.

• Explain the operation of the appliance to the user.

Additional information (Fig. 8)

• If the appliance does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow-rate limiter [1.-3.].
• Priority circuit for the combination with electrical storage heaters: For operation with a priority circuit, a special load shedding relay BZ 45L21 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction (Wiring diagram).
• The control electronics must be coded when operated with a load shedding relay. Remove the keying nose on the electronics [4].

3.1 Solar heated

Only for appliances that are suitable for solar heating systems:

The appliance can only heat prewarmed water to a max. of 60^ If the cold water supply exceeds a temperature of 55^ the water will not be warmed any further.

Important: The cold water supply temperature must not be higher than 55^

If the cold water supply exceeds a temperature of 60^ , a circuit breaker will trigger and shut the appliance off. Therefore, the residential plumbing must be equipped with a thermostatic premixer that will limit the cold water supply temperature to a max. of 55^ by appropriately mixing in cold water.

Dimensions (Fig. 9)

4 Special accessories

• Priority switch (load shedding relay) BZ 45L21: for operation with a priority circuit
• Mounting kit BZ 45K23: for surface mount installation
• Only for appliances that are suitable for solar heating systems: Thermostatic premixer for installation in the domestic plumbing when using preheated water

5 Environmental protection/disposal

Environmental protection is a fundamental corporate strategy of the Bosch Group.

The quality of our products, their economy and environmental safety are all of equal importance to us and all environmental protection legislation and regulations are strictly observed.

We use the best possible technology and materials for protecting the environment taking account of economic considerations.

Packaging

Where packaging is concerned, we participate in country-specific recycling processes that ensure optimum recycling.

All of our packaging materials are environmentally compatible and can be recycled.

Used appliances

Used appliances contain valuable materials that can be recycled. The various assemblies can be easily dismantled. Synthetic materials are marked accordingly. Assemblies can therefore be sorted by composition and passed on for recycling or disposal.

Used electrical and electronic appliances

Electrical or electronic devices that are no longer serviceable must be collected separately and sent for environmentally compatible recycling (in accordance with the European Waste Electrical and Electronic Equipment Directive).

To dispose of old electrical or electronic devices, you

should use the return and collection systems put in place in the country concerned.

Batteries must not be disposed together with your household waste. Used batteries must be disposed of in local collection systems.
