7. Trouble-Shooting
The UVC bulb should be replaced after approximately 8,000 oper-
ating hours since the UVC performance decreases dramatically
after this time.
Only bulbs of type 9 W TC-S (UV-C) should be used
(e. g. Radium: Puritec NSE 9-270, Philips: TUV PL-S 9 W or
Sylvania: G 9 LYNX-S GERMICIDAL). The UVC lamp can be
ordered as a replacement part from GARDENA Service.

1. Unplug the mains plug of the UVC unit and pump.
2. Turn the cap
J
of the UVC unit
1
and
remove carefully
2
(bayonet fitting).
3. Carefully unscrew the ring
K
.
4. Pull off the glass tube
L
.
(It may be relatively difficult to re-
move the glass tube due to mineral
deposits.)
5. Take out the bulb
V

with a new one.
6. Reassemble the UVC unit in reverse
order.

the O-ring
N
fits properly on the
