Scope of delivery

Product description
The electronic continuous-flow heater is suitable for closed (pressurised) connections. It heats the water as it passes through the appliance. The continuous-flow heater switches on and heats the water when the warm water tap is opened. It switches off as soon as the tap is closed. The appliance may not be operated with pre-heated water, as otherwise the overtemperature protection will trip. This installation and operating instruction manual describes various appliance types:

Over-sink appliances:

• TR4000 6 EB and TR4000 8 EB: for fixed electrical connection

Undersink appliances:

• TR4000 4 ET and TR4000R 4 ET: with plug connection
• TR4000 5 ET, TR4000 6 ET and TR4000 8 ET: for fixed electrical connection Only for permanently installed appliances: The device is compliant to IEC 61000-3-12.

Preparations for installation
(Fig. 2)

• Shut off the water supply before connecting the appliance. The electrical connection must be disconnected from the mains supply. Unscrew the fuse or switch off the circuit breaker.

For all appliances
A clearance of about 60 mm on all sides of the appliance is required for installation.

• Observe the technical appliance data.
• Break out the installation bracket from the rear of the appliance (A).

Only for TR4000 4 ET and TR4000R 4 ET

• Break out one of the side knock-outs (B1) provided for an incoming electrical supply cable.
• Feed the desired length of the incoming electrical supply cable downwards through the knock-out (B2).
• Important: Connect the unit only to a mains socket with protective contact that is installed according to regulations. Do not use an extension cord. If necessary, equip the unit with a longer cord.

Only for TR4000 5 ET, TR4000 6 ET, TR4000 6
EB, TR4000 8 ET and TR4000 8 EB (fixed electrical connection)

• Press the upper and lower latches (C1), then remove the housing cover (C2).

Wall mounting
(Fig. 3)

Undersink appliances

• Attach mounting template D to the wall.
• Mark the locations for the holes; drill the holes and insert the wall plugs.
• Attach the installation bracket to the wall using the screws (D1).

Only for permanently installed appliances:

• Pass the connection cable through the cable grommet, suspend the appliance in the installation bracket and screw it onto the mounting bracket (D2).

Only for appliances with mains plug:

• Suspend the appliance in the installation bracket and screw it onto the mounting bracket (D3).

Over-sink appliances

• Attach mounting template E to the wall.
• Mark the locations for the holes; drill the holes and insert the wall plugs.
• Attach the installation bracket to the wall (E1).
• Pass the connection cable through the cable grommet, suspend the appliance in the installation bracket and screw it onto the mounting bracket (E2).

2.8 Only for TR4000 5 ET, TR4000 6 ET, TR4000 6 EB, TR4000 8 ET and TR4000 8 EB (fixed electrical connection)

• The variants for feed through of cables using flush mounting electrical connection should be observed on the mounting template.
• The cable grommet must completely enclose the connection cable to guarantee optimum protection against dampness. The opening must be sealed watertight if it is damaged.
• Use the openings provided on the rear for mounting.

Water connection

(Fig. 4)

• The tap and outlet fittings must be approved for operation with closed (pressurized) continuous-flow heater system.
• The appliance is only approved for heating water with a specific electric resistance of ≥ 1 300 Ωcm at 15 °C. Your water utility company can give you information about the specific water resistance.

Installation

• Ensure the axial fit of the connection pipes in the nozzles.
• Tighten the union nuts on the nozzles with an open-end wrench and counter hold with a suitable open-end wrench.
• The T-piece (for the pressurised connection) and flexible connection hose are available commercially.
• Exchange the perlator from the tap fixture with the supplied aerator to change the spray pattern of the tap.

Controlling temperature
The supply temperature (probably lower in winter) and pressure fluctuations can influence the temperature of the water leaving the tap.

• Turn the valve slowly in the closed direction for higher temperatures (F1).
• Add cold water for lower temperatures (F2).

Electrical connection

TR4000 5 ET, TR4000 6 ET, TR4000 6 EB, TR4000 8 ET and TR4000 8 EB (fixed electrical connection)

• Connect the appliance on the terminal strip in accordance with the connection schematic.
• Put on the housing cover and push it onto the rear wall of the appliance so that the upper and lower latches engage.

TR4000 4 ET and TR4000R 4 ET
Replacing the Power Supply Cord:

• The power supply cord must be replaced by our customer service only in order to avoid a hazard. The mains plug must be pulled before replacing.

For all appliances

• Vent the continuous-flow heater: Fully open the warm water tap and flush out the appliance for about 1minute (G), until bubbles no longer emerge.

After installation

TR4000 5 ET, TR4000 6 ET, TR4000 6 EB, TR4000 8 ET and TR4000 8 EB (fixed electrical connection)

• Insert the plug into the mains socket.

First start-up

Initial rinsing

• Open the warm water tap and allow water to flow for at least 1minute (flow-rate at least 2 litres per minute). Only then (for safety reasons) will the appliance begin to heat.

Info: The appliance will not heat if the dispensed water flow is interrupted prematurely. Open the warm water tap again and allow water to flow for at least 1minute.

Tip: Should the appliance not start because of a reduced flowrate, remove the perlator, aerator or similar before starting and repeating the process.

Important: If the continuous-flow heater does not have sufficient water flow due to low water line pressure in your domestic plumbing system:

• Switch off the circuit-breakers/fuses or remove the mains plug.
• Remove the flow-rate limiter (H1–H4).

Controlling temperature
The supply temperature (probably lower in winter) and pressure fluctuations can influence the temperature of thewater leaving the tap (see Fig. 4, left: pressurised [closed], right: unpressurised [open]).

• Turn the valve slowly in the closed direction for higher temperatures (F1).
• Add cold water for lower temperatures (F2).
• Hand over the installation and operating instructions to the user and explain how the appliance operates.

The temperature of the water leaving the tap is dependent on the flow of water:

Operating instructions

Please read and observe the detailed safety instructions at the start of these instructions!

• Important: The appliance may never be exposed to frost!

WARNING
Risk of electric shock!
Switch off the mains voltage supply immediately if a fault occurs (TR4000 5 ET, TR4000 6 ET, TR4000 6 EB, TR4000 8ET, TR4000 8 EB) or disconnect the plug from the mains supply (TR4000 4 ET, TR4000R 4 ET).

• Immediately shut off the cold water supply to the appliance should it leak.

Operation

The electronic continuous-flow heaters of this series operate automatically.

Switching on

• Open the tap fully. The electronic continuousflow heater switches on. The water is heated as it flows through the appliance. The over-sink appliances TR4000 6 EB and TR4000 8 EB feature an automatic operation indicator. The operation indicator lights yellow at half power and red at full power, dependent on the water flow rate.

Switching off

• Close the tap, and the appliance will switch off.

Regulating water temperature

• Open the tap fully, and the appliance switches on.
• Now increase the temperature of the water by reducing the flow of water.

Info: In winter, the temperature of the water supply may be lower, so that the temperature of the water leaving the tap will not be reached. Please proceed as described under “Water connection”.

Cleaning

Do not use aggressive or abrasive cleaning detergents! Do not use a steam cleaner.

• Clean appliance externally with amild cleaning agent.
• Clean the dirt and lime scale deposits in the aerator filter.

Maintenance

Repairs and maintenance may only be carried out by an authorised customer service representative to avoid potential sources of danger.

• The electrical mains supply and the water supply must be shut off before all work on the appliance.

Customer Service

We ask you to always provide the E-No. and the FD-No. of your appliance when calling in a customer service engineer. You will find the number between both water connection nozzles of the continuous-flow heater.
