2.6 Function

• Water comes in through the cold water inlet.

• The flow switch senses water is passing through the

unit. If it detects more than the pre-set level, the

unit’s heating the elements switch on. This is shown

by the neon light glowing.

• 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.

Depending on the region 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 Installation

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:

B Disconnect electric supply.

B Disconnect cold and hot water pipes from fittings on

bottom of heater. Allow water to drain out (have a

catch basin ready).

B 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)

DANGER: Risk of electric shock!

B For safety reasons, disconnect the power

supply to the heater before any service or

testing is performed.

WARNING:

B 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:

B The installation must only be performed

by a qualified person in accordance with

these instructions.

B Bosch Thermotechnology Corp. is not

responsible for improperly installed

appliances.

WARNING:

B 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:

B 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:

B Do not install the Tronic 3000C Pro in a

room where there is a chance of freezing.

NOTE:

B Read entire instructions.

B Check the pressure of the main water

supply.

Installation | 9US

6 720 647 088 (2011/09)

4.3 Water connections

B 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.

B We recommend that you use ½" copper or high

pressure flex connections.

B Use Teflon tape for sealing pipe threads. Do NOT use

pipe dope.

B 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.

B The inlet and outlet are clearly marked on the unit.

They each have a ½" NPT connector.

B 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.

B If the unit is to supply a sink, we recommend that you

use aerators, which you can get from your local

distributor/dealer.

B 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.

B For water analysis data call your local water

department, or if on a well, have well water analyzed

periodically.

If water quality exceeds one or more of the values

specified below, Bosch recommends consulting a

local water treatment professional for water

softening/conditioning options.

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.

WARNING:

B The unit must be installed by a qualified

electrician.

B The unit must be grounded.

B Connect the unit to power.

5.1 Sink

B Check that the power is switched on at the circuit

breaker panel.

B 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 setting the flow rate. Refer to appendix on

page 14 - correct flow vs. temperature.

If the unit has been used recently:

B 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

B Ensure the service valves are open and check that no

pipe joints leak.

B Turn on the hot tap fully at the sink.

B 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 14:

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.

B Check that the unit works correctly when the sink tap

is closed and then opened again; if not adjust the

service valve slightly.

B The outlet shut off valve can be used to regulate

temperature or flow of water from the unit.

B Remove nameplate in direction of Arrow A (Fig. 7).

B Adjust the temperature setting using a screwdriver on

the spindle as shown by arrow B (Fig. 7).

Fig. 7 Temperature adjustment spindle

B Replace the nameplate.

WARNING:

B 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.

When using the hot water at a fixture, open

tap fully. To regulate hot water temperature,

adjust the temperature dial and flow rate as

recommended in the Appendix on page 10.

NOTE:

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.

(see graph above).

If necessary, adjust the outlet service valve

until the water comes out of the tap at the

desired temperature (increase flow for

cooler water, decrease flow for hotter

water). The heater will then maintain the set

temperature in the summer months

reducing the power automatically.

When inlet water temperature increases

during the summer months, the heater will

maintain set temperature by reducing the

power automatically. In cases of extremely

warm incoming water supply, open service

valves fully to ensure maximum flow through

the unit.
