FLOW RATES & WATER TEMPERATURES
The temperature of the water coming flowing from the unit depends on:
• The temperature of the mains water supply
• The water flow rate through the unit
• The power level of the unit
• The electric supply voltage
The temperature of the water supply can vary from 5°C in the winter to about 20°C in summer,
with an average of about 12°C. The table below shows a scenario of the water temperature you
can expect at different flow rates in litres/minute.

CLEANING THE SPRAYHEAD
IMPORTANT
: Before cleaning, turn off the unit
at the isolation switch to avoid the handwash
being accidentally switched on. Cleaning can be
carried out with the swivel arm removed or still
attached to the handwash unit.
DO NOT use powerful abrasive or solvent
cleaning fluids when cleaning the sprayhead
assembly as they may damage the plastic
fittings.
The sprayhead is a critical part of the unit. In
order to maintain maximum performance, the
sprayhead assembly should be cleaned at regular
intervals to prevent build up of deposits from the
water supply. Blocked spray holes can reduce the
water flow to such an extent that it will cause
the thermal cut-out or PRD to operate.
When the unit is first installed the sprayhead
assembly may need cleaning due to debris that
may be left in the pipe work after installation.
Following this, the frequency of cleaning will
depend upon the type of water available. Hard
water areas may require cleaning once a week
whereas soft water areas may only require
cleaning every six months.
Procedure
Unscrew the sprayhead assembly from the
swivel arm and separate the sprayplate from the
sprayhead (
fig.14
). Clean with a suitable brush,
ensuring all traces of scale are removed from the
spray holes. Rinse in clean water and refit the
assembly.
