8 | Installation
▶ 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.
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:
▶ The unit must be installed by a qualified
electrician.
▶ The unit must be grounded.
▶ Connect the unit to power.
4.3.1 Water quality
Water quality can have an impact on appliance longevity and
may not be covered under the manufacturer's warranty.
▶ 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.
