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
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.
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:
▶ The installation must only be performed
by a qualified person in accordance with
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.
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.
