Installation Considerations
•
For best results, Hansgrohe recommends
that this unit be installed by a licensed,
professional plumber.
•
Please read over these instructions thor-
oughly before beginning installation.
Make sure that you have all tools and sup-
plies needed to complete the installation.
•
Inspect the ShowerArc thoroughly for ship-
ping damage before beginning installation.
•
The installation shown on page 2 is ideal
for users of approx. 5'11" in height The
installation height may be increased, if
desired. All measurements, including the
minimum ceiling height, must be increased
as well.
•
The ShowerArc requires 1/2" NPT female
fittings, one for the hot supply and one for
the cold supply, recessed 3/8"
behind the surface of the
finished wall.
•
The thermostatic mixing valve may be
installed on either side of the shower. For
proper operation of the thermostatic mixing
valve, the hot supply must enter the valve

on the left and the cold supply must enter
the valve on the right. If the valve is cross-
connected, it cannot function correctly.
The difference in water pressure between
the hot and cold supplies should not
exceed 10 psi or the thermostatic mixing
valve cannot work properly.
The hot and cold supplies must be thor-
oughly flushed before installation of the
ShowerArc.
The finished wall surface (tile,
etc) must be installed before
the ShowerArc can be installed.
Use caution when drilling the mounting
holes. Be careful not to drill into water
lines!
Protection against backflow is provided by
check valves. The check valves should be
removed and cleaned yearly -- please see
the maintenance note on page 29.
The ShowerArc is not for use with an
instantaneous water heater.
