2.7 Function
How the water heater works:
• Water comes in through the cold water inlet.
• The flow switch senses how much water is passing through
the unit. If it detects more than the preset level, the unit’s
heating elements switch on. This is shown by the neon light
glowing.
• The water is heated instantly as it passes through the
copper heat exchanger tube.
The temperature of the water coming out of the unit depends
on:
• The voltage of the electrical supply,
• The temperature of the incoming water supply,
• The setting of the power selector,
• The flow rate,
• The power rating of the unit.
• Depending on the region of the country, the temperature of
the water supply can vary between 40 °F in winter to 70 °F
in summer, with an average of 50 °F.
Fig. 3
[A] Manual reset thermal cut out
The table below shows the rise in water temperature you can
expect from the unit:
Manual reset thermal cut-out
The unit has a thermal cut-out (Fig. 1 ) which is mounted on
the heat exchanger tube. This will switch off the heater
elements if the water temperature goes above 194 °F.
If the cut-out trips it will need to be reset manually inside the
unit. This cut-out will only operate in exceptional
circumstances (Fig. 3 ). Call your service person or Bosch
Water Heating if this happens frequently.
The heater is designed for cold water supply
only. Do not supply with pre-heated water.

4.1.1 Freeze prevention
Introduction
Please note that the installation manual states that the water
heater must not be installed in a location where it may be
exposed to freezing temperatures. If the heater must be left in
a space that is likely to experience freezing temperatures, all
water must be drained from the heater.
Freeze damage is not covered under the warranty.
Draining the heater
Due to the shape of the heat exchangers and connecting pipe,
it is extremely difficult to get all of the water out of the heater.
Follow the procedure below to best minimize the chance of
freezing:
▶ Disconnect electric supply.
▶ Disconnect cold and hot water pipes from fittings on
bottom of heater. Allow water to drain out (have a catch
basin ready).
▶ After allowing all water to drain out, the heater should be
blown out with low pressure compressed air to remove as
much water as possible from water heater modules. Bursts
of air work better than continuous flow.
Remember, these suggestions are only made to help minimize
the potential for freeze damage and are not to be construed as
the guaranteed method for dealing with freeze possibilities.
4.2 Installing the Tronic 3000C Pro
To operate correctly the unit needs the following running
pressures:
Sink
• Min: 10 psi (0,7 bar)
• Max: 150 psi (10,3 bar)
4.3 Water connections
▶ The unit should be connected directly to the main cold
water supply and not to pre- heated water. The unit should
be installed with service valves on both the inlet and outlet.
These valves can be used to turn off the water supply to the
unit if it needs servicing, or to reduce the water flow if it is
too high.
▶ We recommend that you use ½" copper or high pressure
flex connections.
▶ Use Teflon tape for sealing pipe threads. Do NOT use pipe
dope.
▶ Remember to keep the hot water pipe runs as short as
possible. In some cases it may be worth fitting a second
unit to serve an additional fixture.
▶ The inlet and outlet are clearly marked on the unit. They
each have a ½" NPT connector.
▶ If the unit is to supply a sink, we recommend that you use
aerators, which you can get from your local distributor/
dealer.
▶ If the unit is to supply more than one sink, the aerator
should be the same at each tap if they are to be used at the
same time. If not, one outlet will take all the water.
▶ After the unit has been plumbed in, and before you wire it,
flush it with water to remove any debris or loose particles.
Failure to do so may make the unit inoperable.
WARNING:
▶ ELECTRICITY IS EXTREMELY
DANGEROUS. TAKE EXTRA
PRECAUTIONS AND ENSURE ALL
CIRCUIT BREAKERS ARE OFF BEFORE
PERFORMING ANY WORK TO THE
HEATER.
Use of agents like anti-freeze are not allowed
as they may cause damage to the water
heater’s internal components.
WARNING:
▶ Do not install the Tronic 3000C Pro in a
room where there is a chance of
freezing.
NOTICE:
▶ Read entire instructions.
▶ Check the pressure of the main water
supply.
As a condition of installing this product in the
Commonwealth of Massachusetts a
pressure relief valve must be installed on the
cold water side by a licensed plumber. MGL
42 Section 19.

Troubleshooting | 13
▶ Check that the power is switched on at the circuit breaker
panel.
▶ Turn on the hot tap FULLY.
If you do not turn the tap full on, you will find that the
temperature of the water may vary. The hot water
temperature can then be set by adjusting the flow.
If the unit has been used recently:
▶ run the water through for a few seconds to let the
temperature settle down.
If the unit has been used recently, You may initially get a
short burst of very hot water from the unit.
If a second tap connected to the unit is also turned on, the hot
water will be shared between the two, therefore the flow and/
or the temperature of the water will decrease.
5.2 Adjusting the flow
Checking for leaks
▶ Ensure the service valves are open and check that no pipe
joints leak.
▶ Turn on the hot tap fully at the sink.
▶ Adjust the outlet service valve until the water comes out of
the tap at the required temperature, (increase flow for
cooler, decrease for hotter). Refer to Table 4 , page 7
for expected temperature rise at given flow rates.
▶ Check that the unit works correctly when the sink tap is
closed and then opened again; if not adjust the service
valve slightly.
▶ The inlet service valve should not be used to regulate
temperature.
6 Troubleshooting
If the problem persists:
The person who initially installed the unit is probably the best
one to contact for help. You can also call Bosch
Thermotechnology Corporation at 603-552-1100 or visit
www.bosch-climate.us. Please have this guide with you when
you call.
When using the hot water at a fixture, open
tap fully. To regulate hot water temperature,
adjust water flow accordingly as directed in
Section 5.2.
NOTICE:
If the unit is servicing a single lever faucet
you may need to restrict the cold water
supply to the faucet to balance water
pressure and improve performance.
NOTICE:
▶ Before leaving the site, the installer
should demonstrate the unit to the user
and give him/her this guide.
WARNING: Always switch off the electricity
supply to the unit before you remove the
cover.
