Cleaning the scale trap
INSTRUCTIONS FOR INSTALLERS AND SERVICE ENGINEERS ONLY
It is recommended in hard water areas, the
scale trap is periodically cleaned to maintain the
performance of the shower.
It is essential that this operation is carried out by
a competent person.
SWITCH OFF THE ELECTRICITY SUPPLY AT
THE MAINS.
Remove the cover and unplug the ribbon cable.
The scale trap is located at the lower left-hand
side of the unit. Unscrew the single central
screw (fig.28) then pull off the cap complete
with ‘O’ rings. Be aware of water discharging as
the heater can empties Clean out the trap and
remove all sediment. Flush the can through by
leaving the cap off and switching on the power
at the isolating switch.
Note: Make sure the water that flows out of the
scale trap will safely flow to waste.
Switch off the power at the isolating switch.
Replace the cap making sure the ‘O’ rings are
in place and free from debris. Secure with the
central screw.
Switch the power back on again at the isolating
switch to enable the can to fill with water. Check
for water leakage at the scale trap. When water
flows smoothly from the showerhead, stop the
flow by switching the power off at the isolating
switch.
Reconnect the connection cable, replace the
cover and secure with the three screws.
