Wait until you are sure-it has completely thawed
out before you switch it on.
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 setting the flow rate. Refer to
appendix on page 10 - 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. You may
initially get a short burst of very hot water
from the unit,
• It 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.
Installing the Powerstream Pro

the electric cable through the side or
through the back of the unit,
• If it is gong to be through the side of the
unit, cut out the plastic lug to expose the
rubber sleeve (diagram 2.)
Plumbing in the unit
Fitting the pipes
• The unit should be connected directly to
the main cold water supply and not to preheated water. The unit should be installed
with service valves on both the inlet and
outlet.
• We recommend that you use ½"
• If it is going through the back of the unit, cut
through the grommet on the backplate with a
sharp knife. Make sure that you do not remove

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.
before you wire it, flush it with water to
remove any debris or loose particles.
Failure to do so may make the unit
inoperable.
Connecting the unit to the pipes
• The inlet and outlet are clearly marked
on the unit. They each have a ½" NPT
connector.
• Install a ball valve in the cold water line.
This valve 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.
Mounting on the wall
• Undo the retaining screws on the cover
and take the cover of the unit. Hold the
backdate in position against the wall while
you mark the four mounting holes.
• Drill the holes and secure the unit to the
wall using the four no. 8 wood screws
supplied
WARNING - IMPORTANT
Do not install a non-return check valve
within 6 feet of the inlet.
• If the unit is to supply a sink, we
recommend that you use aerators, which
you can get from your local
distributor/dealer.
• 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

Funcionamiento del Powerstream Pro
El agua entra por el tubo de entrada.
El conmutador de caudal detecta el agua que ha
pasado por la unidad. Si detecta más del nivel
preajustado, se activan las unidades que calientan
los elementos. Esto se indica con la luz neón
encendida.
El agua se calienta de forma instantánea a medida
que pasa por el tubo intercambiador térmico de
cobre.
La unidad es termostática, es decir, enciende y
apaga los elementos para mantener una temperatura
de salida constante.
La temperatura del agua que sale de la unidad
depende de lo siguiente:
• El voltaje del suministro eléctrico.
• La temperatura del agua que entra.
• El ajuste del control de temperatura.
Un caudal ajustado incorrectamente puede tener
también un efecto negativo en la temperatura.
Según la región del país, la temperatura del
suministro de agua puede variar entre 4ºC en
invierno a 21ºC en verano, con una media de unos
10ºC. Las condiciones climáticas extremas pueden
hacer que la temperatura de entrada sobrepase estos
límites, por lo que será necesario ajustar el orificio
de ajuste de temperatura o el caudal del agua de
entrada.
La unidad incluye un cierre térmico bipolar
montado en el tubo del intercambiador térmico.
Cuando se dispara el cierre, se deberá reajustar
manualmente dentro de la unidad.
Este disyuntor sólo se disparará en circunstancias
excepcionales (diagrama 7). Llame al personal de
servicio o a Bosch Water heating si esto sucede con
frecuencia.
ADVERTENCIA -
Apague siempre el suministro eléctrico en la
unidad antes de retirar la tapa.
Diagrama 7: Disyuntor térmico
Starting up the Powerstream Pro
Checking for leaks
• Lot the water run through the unit for a
few seconds. Check that no pipe joints
leak.
Adjusting the flow
Turn the service valves on, then -
• Turn on the hot tap fully at the sink
• Adjust the outlet service valve till the
water cones out of the tap at the
recommended flow rate for the required
temperature.
Refer to Appendix on page 10 :
Correct flow vs. Temperature.
If the required temperature is different
from the factory setting 113°F (45°C),
turn the Adjustment Spindle (Diagram
5) 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.
When using the hot water open the tap fully
so that the water temperature is always the
same. If hotter water is desired 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.
IMPORTANT
Before leaving the site, the installer should
demonstrate the unit to the user and give
him/her this guide.

How the Powerstream Pro works
Water comes in through the inlet tube.
The flow switch senses water has passed
through the unit. If it detects more than the preset level, the units heating the 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 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 conning 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 badly set flow rate can also have a negative
effect on the 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.
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 (Diagram 7.) Call your service
person or Bosch Water Heating if this happens
frequently.
WARNING Always switch off the electrical supply to the
unit before you remove the cover.
