Safety First
Never submerge the unit in water.
Always switch off the unit if there is
no water running through it to pre-
vent overheating. This unit pro-
duces harmful ultra violet light. Do
not look directly at the unshielded
bulb as damage to the eyes may
occur.
Monitoring of lamp operation
should only take place by looking
through the transparent hose con-
nectors.
When connecting the unit to the
mains it is recommended that an
inline residual current device
should be installed or that the unit
be wired directly into the mains
using a residual circuit breaker.

Maintenance and Care
When carrying out any maintenance
the unit must be disconnected from
the mains. Always remove inlet and
outlet hoses and drain the unit of
water before cleaning. Carefully dis-
mantle the unit by first unscrewing
the unit cap and removing the bulb.
The quartz tube may be loosened by
using a small coin or a screwdriver
and can then be carefully removed.
Clean with a soft cloth to avoid
scratching the quartz. When
reassembling ensure that the sealing
rings are properly seated (lubricate
with a small amount of petroleum
jelly if necessary)
The UV-C bulb should be replaced
after 8000 hours (about once per
year) in order to guarantee efficient
operation.
Replacement bulbs and quartz tubes
are available from your local
