Operating instructions

• Before using the appliance, please read the instructions
carefully and observe them!
• Important: The appliance may never be exposed to frost!
WARNING:
Risk of electric shock!
If a fault occurs, immediately disconnect the plug from the power
supply!
Immediately shut off the cold water supply to the appliance should
it leak.
Please read and observe the detailed safety instructions at the start
of these instructions!
Operation (Fig. 8)
The small water heater heats and stores drinking water up to approx. 85 °C.
5.1

Setting the water temperature

• The required outlet temperature from 35 °C to 85 °C can be set with
the rotary selector switch.
or:
• Set the required fixed outlet temperature (A):
Frost protection
1 Approx. 38 °C (soft lock-in)
eco Conserve energy approx. 60 °C (soft lock-in)
3 Hot water approx. 85 °C
The pilot lamp lights up during heat up.
Water drips out of the tap with oversink appliances.
The appliance with be covered more quickly with limescale at higher
temperatures.
Tip: Set the rotary selector switch to "eco" to operate the appliance
economically and to reduce the effects of limescale.
Note: If the appliance has not been used for an extended period,
e. g. during a holiday, allow the water to briefly heat up to stage "3".
5.2

Limitation of the water temperature

Limit the outlet temperature to avoid scalding with hot water:
• Set the rotary selector switch to "●".
• Open the cover of the rotary selector switch.
• Select between "1" = approx. 38 °C (B2) or "eco" =
approx. 60 °C (B1).
• Close the cover.
5.3

Switching off

Set the rotary selector switch to "●" (A). The heating is switched off.
5.4 Undersink appliances only TR3500TO 5 T and
TR3500TOR 5 T
Drip stop
The drip stop function prevents expanding water from dripping from the
tap during heat up. If water is heated, the gasses (air) dissolved in it will
be released by the water.
Depending on the quantity of gas released – particularly when a higher
temperature is selected – it can force residual water from the tap.
Pressure stop (Fig. 9)
The appliance features pressure switch off. The pressure switch off
indicates when the tap is clogged by limescale (low or no flow). When
Tronic 2500 TO | Tronic 3500 TO | Tronic Store Advanced – 6 720 876 005 (2021/07)
water pressure exceeds 0.25 Mpa (2.5 bar) it even detects if the
appliance has been incorrectly connected with the water line during
initial installation. The pressure switch off automatically shuts off the
water inlet and prevents rupturing of the tank.
It the pressure stop has tripped, a red pin will appear at the top of the
appliance (C1).
• The fault must be corrected (see chapter 6 "A fault, what to do?").
• After the fault has been corrected, the red pin can be pushed back in
easily (C2). The water inlet is now free.
• Please contact customer service if this occurs repeatedly.
Important: Do not block the path of the pin (C1) with objects.
5.5

Cleaning

Do not use aggressive or abrasive cleaning detergents!
Do not use a steam cleaner.
• Clean appliance externally with a mild cleaning agent.
• Clean the dirt and lime scale deposits in the aerator filter.
5.6

Descaling

• Descale the outlet pipe with commercially available descaling agent
or vinegar.
• Please observe the manufacturers warnings when descaling.
If the water flows significantly slower when the tap is fully opened, the
small water heater and tap should be descaled by a specialist. Otherwise,
the pressure stop may trip due to an unpermissible high pressure.
5.7

Maintenance

The following 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.
Exchange of the electrical connection cable
When the electrical cable is visibly damaged:
• Switch off the device, unplug the mains plug and contact customer
service.
Cleaning the inlet filter (Fig. 10)
When the flow of water is too low and the inlet filter in the tap is descaled:
• Contact customer service and get the inlet filter (D) cleaned.
