Bar mixer shower

PLUMBING REQUIREMENTS
DO NOT
choose a position where the mixer
shower could become frozen.
DO NOT
connect to any form of tap or fitting
not recommended by the manufacturer.
DO NOT
use jointing compounds on any pipe
fittings for the installation,
DO NOT
solder fittings near the mixer shower
as heat can transfer along the pipework and
damage the shower.
DO NOT
subject the mixer shower to a water
temperature above 80°C during installation, use,
maintenance or disinfection.
IMPORTANT:
• The layout and sizing of pipework
MUST
be such that nominally equal inlet supply
pressures are achieved and the effects of
other draw-offs are minimised.
• The pipework should be installed such
that other taps and appliances being
operated elsewhere on the premises do not
significantly affect the flow
• When connecting pipework avoid using tight
90° elbows; swept or formed bends will give
the best performance.
• The hot water pipe entry
MUST
be made to
the left-hand side inlet, marked HOT, ‘H’ or
with a red/orange label.
• Suitable isolating valves (complying with
Water Regulations and Bylaws)
MUST
be
fitted on the hot and cold water supplies
to the shower as an independent means
of isolating the water supplies should
maintenance or servicing be necessary
position as close as is practicable to the water
supply inlets of the mixer shower. If this
isolator is fitted in a loft space, the loft must
have a fixed access ladder and be boarded,
with appropriate lighting from the access
point to the isolator.
• Flush pipework to clear the system of debris
and check for leaks before connecting to the
mixer.
Commercial Applications
• For commercial applications in-line filters are
recommended.
Hard Water Areas
a. If it is intended to operate the shower
in areas of hard water (above 200-ppm
temporary hardness), a scale inhibitor may
have to be fitted. For advice on the scale
inhibitor, please contact Customer Service.
b. For best performance the shower head
MUST
be regularly cleaned to remove scale and
debris.
WATER SYSTEM REQUIREMENTS
This mixer shower is suitable for:
• Gravity water systems
• Pumped gravity systems
• Fully modulating type combination boilers
• Multi-point hot water heaters
• Thermal storage
• Unvented systems
When installing this mixer shower with a
combination or multi-point boiler, it may be
necessary to install flow regulation.
Check that the appliance is capable of delivering
hot water at a minimum switch-on flow rate
of 3 litres per minute. At flow rates between 3
and 8 litres per minute, the appliance
MUST
be
capable of raising the water temperature to 52°C
minimum.
Water temperature at the inlet of the mixer
shower
MUST
remain relatively constant
when flow rate adjustments are made - refer
to the appliance operating manual to confirm
compatibility with this mixer shower.
Where thermal store systems and instantaneous
gas water heaters are used, if excessive draw-off
takes place, the appliance may not be able to
maintain an adequate output temperature.
This could result in the shower temperature
becoming noticeably cooler.
Flow regulators can be fitted with high-pressure
water systems to reduce flow rate and assist
economy.
The hot supply temperature
MUST
remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.
