6 | Regulations
• The water is heated instantly as it pas ses through the
copper heat exchanger tube.
• The unit is Thermostatic i.e. it will switch the elements on
and off in order to maintain a constant outlet temperature.
The temperature of the water coming out of the unit depends
on:
• The voltage of the electrical supply,
• The temperature of the incoming water.
• The setting of the temperature dial.
A high flow rate can also negatively effect the hot water
temperature.
Dependingontheregion of the country, the temperature of the
water supply can vary from 40°F in winter to about 70°F in the
summer, with an average of about 50°F. Extreme weather
conditions can cause the inlet temperature to go outside these
boundaries, making it necessary to adjust the Temperature
Adjustment Spindle and/or the inlet water flow
Manual reset thermal cut-out
• The unit has one double pole thermal cut out which is
mounted on the heat exchanger tube.
• When tripped the cut out needs to be reset manually inside
the unit.
• The cut-out will trip only in exceptional circumstances (Fig.
2 ). Call your service person or Bosch Thermotechnology
Corp. if this happens frequently.

4.1 Important information
Please follow these instructions. Failure to follow instructions
may result in:
• Damage or injury.
• Improper installation/operation.
• Loss of warranty.
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
beinstalledwithservice 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.
WARNING:
▶ This heater must be electrically
grounded in accordance with the most
recent edition of the National Electrical
Code. NFPA 70. In Canada, all electrical
wiring to the heater must be in
accordance with local codes and the
Canadian Electrical Code, CSA C22.1
Part 1.
DANGER:
▶ Theinstallationmustonlybeperformed
byaqualifiedpersoninaccordancewith
these instructions.
▶ Bosch Thermotechnology Corp. is not
responsible for improperly installed
appliances.
WARNING:
▶ The heater must only be mounted in a
vertical position with the water fittings
located at the bottom of the heater.
Under no circumstances should the
heater be mounted differently.
WARNING:
▶ ELECTRICITY IS EXTREMELY
DANGEROUS. TAKE EXTRA
PRECAUTIONS AND ENSURE ALL
CIRCUIT BREAKERS ARE OFF BEFORE
PERFORMING ANY WORK TO THE
HEATER.
Useofagentslikeanti-freezearenotallowed

▶ 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 more than one sink, a similarly flow
restricted aerator should be used at each tap. If not, the
highest flowing outlet will take all the water under dual
usage.
▶ If the unit is to supply a sink, we recommend that you use
aerators, which you can get from your local distributor/
dealer.
▶ 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.
4.3.1 Water quality
Water quality can have an impact on appliance longevity and
may not be covered under the manufacturer's warranty.

5.1 Sink
▶ 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 can be
adjusted by altering the temperature dial and correctly
settingtheflowrate.Refer toappendixonpage14-correct
flow vs. temperature.
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
▶ 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 till the water comes out of
the tap at the recommended flow rate for the required
temperature. Refer to Appendix on page 12: Correct flow
vs. Temperature.
If the required temperature is different from the factory
setting, turn the Adjustment Spindle (Fig. 7 ) until the
outlet temperature is correct.
▶ Check that the unit works correctly when the sink tap is
closed and then opened again; if not adjust the service
valve slightly.
▶ The outlet shut off valve can be used to regulate
temperature or flow of water from the unit.
▶ Remove nameplate in direction of Arrow A (Fig. 7 ).
▶ Adjust the temperature setting using a screwdriver on the
spindle as shown by arrow B (Fig. 7 ).
Fig. 7 Temperature adjustment spindle
▶ Replace the nameplate.
WARNING:
▶ Do not use the unit if you think it may be
frozen, as this could result in serious
damage to the unit. Wait until you are
sure it has completely thawed out
before you switch it on.
WARNING:
Before turning on power, open cold water
shutoff valve to the unit and turn on all hot
water taps supplied by the unit. Flow water
out the tap(s) until all air has purged from
the unit and plumbing.

4 Instalación
4.1 Información importante
Por favor siga estas instrucciones. Si no lo hace puede resultar
en:
• Daños o lesiones.
• Instalación y/o funcionamiento inadecuado.
• Pérdida de la garantía.
4.1.1 Prevención de congelamiento
Introducción
Tenga en cuenta que el manual de instalación indica que el
calentador de agua no debe instalarse en un lugar donde pue-
den estar expuestos a temperaturas de congelación. Si el
calentador se debe dejar en un espacio que puede experimen-
tar temperaturas bajo cero, toda el agua debe ser drenada de
éste.
Las fallas por congelación no están cubiertas por la garan-
tía.
Vaciado del calentador
Debido a la forma de los intercambiadores de calor y la tubería
de conexión, es muy difícil conseguir extraer toda el agua del
calentador. Siga el procedimiento para reducir al mínimo las
posibilidades de congelamiento:
▶ Desconecte el suministro eléctrico.
▶ Desconecte las tuberías de agua fría y caliente de las
conexiones en la parte inferior del calentador. Deje que el
agua drene hacia afuera (tenga lista una cubeta de cap-
tura).
▶ Despuésdepermitirque toda elaguadrenehacia afuera, el
calentador se debe soplar con baja presión de aire compri-
midoparaeliminarlamayorcantidaddeaguaposibledelos
módulos calentadores de agua. Las ráfagas de aire funcio-
nan mejor que el flujo continuo.
Recuerde que estas sugerencias se hacen solamente para ayu-
dar a minimizar la posibilidad de daños por congelación y no
debe interpretarse como el método garantizado para hacer
frente a las posibilidades de congelación.
PELIGRO: ¡Riesgo de choque eléctrico!
▶ Por razones de seguridad, desconecte
el cable de suministro eléctrico al apa-
rato antes de llevar a cabo cualquier
prueba o mantenimiento.
ADVERTENCIA:
Este aparato debe tener tierra física de
acuerdo con la edición más reciente del Có-
digo Eléctrico Nacional. NFPA 70. En Cana-
dá, todo el alambrado eléctrico debe
cumplir con los reglamentos locales y el Ca-
nadian Electrical Code, CSA C22.1 Parte 1.
PELIGRO:
▶ La instalación sólo debe ser realizada
por una persona calificada de acuerdo
con estas instrucciones.
▶ Bosch Thermotechnology Corp. no se
hace responsable de los aparatos que
no estén bien instalados.
ADVERTENCIA:
▶ Elaparatosólodebe ser montadoenpo-
sición vertical con las conexiones de
agua situadas en la parte inferior del ca-
lentador. Bajo ninguna circunstancia se
debe montar el calentador de manera
diferente.
