portant: Lead the connection cable (7) through the cable opening in the bottom strainer casing (2) and route the cable
such that pinching is avoided.
Assembling the unit (Figure E)
Assemble the reduction element (13), branch valve (12), nozzle tube (11) with the clamping screw (10), nozzle mount-
ing (9) and nozzle insert (8), then screw the assembly on the connection thread of the UVC water housing (26) includ-
ing the sealing ring (14). The fountain height and shape depend on the nozzle insert (8) used.
If required, connect an additional hose for features or a water course to the second separately regulated connection of
the branch valve (12). For this purpose, screw the reduction element (15) and the stepped hose adapter (16) on the
connection point of the branch valve (12).
Set-up the unit
Place the unit in the pond on a horizontal, firm and sludge free ground and ensure that it is completely covered by
water.
Inserting the nozzle tube (Figures F-H)
Pull the nozzle tube (11) to the desired length. Undo the clamping screw (10), vertically align the nozzle tube (11) and
fasten the clamping screw (10) hand tight.
Adjust the fountain height by means of the regulator (18). Set the water quantity for the second connection point by
means of the regulator (17).
Switching on / switching off (Figure I)
Attention! Dangerous electrical voltage.
If cables or components are defective, unit components and pond water can carry dangerous electrical
voltage.
Possible consequences: Death or severe injury by electrocution.
Protective measures: Disconnect the power plug (19) prior to reaching into the water and commencing
work.
Never operate the unit without water or without pump filter!
In the event of overheating, a fitted temperature monitor switches the UVC lamp off automatically, the lamp automati-
cally switches on again once it has cooled down.
The unit switches on automatically when power connection is established.
Switching on: Plug the power plug (19) into the socket.
Switching off: Disconnect the power plug (19).
Cleaning and maintenance, changing the UVC lamp (Figures J-Y)
Attention! Dangerous electrical voltage.
If cables or components are defective, unit components and pond water can carry dangerous electrical
voltage.
Possible consequences: Death or severe injury from electrocution.
Protective measures: Disconnect the power plug (Figure I, 19) prior to reaching into the water and com-
mencing work.
Opening the filter housing (Figures J-L):
Unscrew the stepped hose adapter (16) prior to removing the branch valve (12). Pull the clamps on both sides of the
bottom strainer casing (2) to the side and lift off the top strainer casing (1). Remove the UVC clarifying unit including
pump (20), foam filters (3, 22), bio surface elements (23) and gravel bags (24). When the aeration stone (25) is con-
nected, put it to the side. Clean the bottom strainer casing (2) and the top strainer casing (1) with clear water using a
brush. Wash out foam filters (3, 22), bio-surface elements (23) and gravel bags (24) under running water. Do not use
chemical cleaning agents as they would kill the micro-organisms in the different filter media. At the beginning, this
entails a reduced filter capacity.
Cleaning the pump (Figures M, N)
Unscrew the pump (28) from the UVC water housing.(26). Unscrew the pump lid (27) by turning counter-clockwise
(bayonet closure), then remove the rotor (29) Clean all components using clean water and a brush. After cleaning the
pump, reassemble in the reverse order.
Cleaning the UVC clarifying unit (Figures O, P)
Note: A safety switch prevents switching on the UVC lamp as long as the housing is removed.
In the UVC water housing (26), the unit head (31) is fastened by means of a bayonet closure. Press on the engage-
ment lug (30) at the unit head (31), turn the unit head (31) counter-clockwise and carefully pull it out of the UVC water
housing (26). Clean the UVC water housing (26) under running water. Check the quartz glass (33) for damage and
clean its outer face with a moist cloth.
