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.
