Installation
Install the unit horizontally, with its feet down (C). Choose a place for the unit which cannot be flooded! Minimum
distance between the unit and the pond: 6.6 ft (2 m). Install the unit so that it is not exposed to direct sun radiation.
Ensure that the unit will never run without water!
During installation (A and B), observe the correct position of the flat seal (2) and the O ring (1).
Start-up
Attention! Ultra-violet radiation.
Possible consequences:
Eye or skin injury from burns.
Protective measures:
−
Never operate the UVC lamp outside its housing.
−
Never operate the UVC lamp in a housing that is defective.
Attention! Breakable glass.
Possible consequences:
Injury of your hands caused by cuts.
Protective measures:
Handle both quartz glass and UVC lamp with care.
Attention!
Never operate the unit without water or without pump strainer casing!
This is how to connect the power supply:
Switching on:
Connect power plug to the socket. The unit switches on immediately when the power connection is
established.
Switching off:
Disconnect the power plug.
Switch on the pump and wait until the unit is filled with water. Check all connections for leaks. Connect the power
supply. Check the function of the UVC lamp and the cleaning rotor at the inspection glass (D-7). Both functions are OK,
when an alternating bright/dark blue light is visible.
Bypass
The water flow can be controlled by the bypass system. The water flows into the unit from the supply (D-4). Depending
on the setting, part of the water can drain directly through the water outlet (D-3) whereas the other part is radiated with
UVC light in the unit and drains via the water outlet (D-1). Optimum cleaning is only achieved when the water through-
flow is correctly set. The correct setting complies with delivery rate (l/h) of your pump; for this purpose, both rotary
handles (D-3, D-4) must be set to the same delivery rate.
Changing the UVC lamp
Change the UVC lamp after approx. 8.000 operating hours (G).
Adhere to the safety information given above! Press the safety engagement lever (D-6), turn the unit head in the
direction of the arrow up to the stop and carefully pull out including the cleaning rotor. Remove the cleaning rotor from
the quartz glass. Undo the clamping screw (H) by turning counter-clockwise, and remove the quartz glass including the
O ring with a slight turning movement.
Pull out the UVC lamp (F) and replace. The rubber band on the original UVC lamp was intended as transport security
and need not be replaced. The UVC lamp only lights up after the complete re-assembly of the unit.
Important! Only use lamps with the designation and rating of which comply with those on the type plate.
Remove the O ring from the quartz glass, clean and check for damage. Clean the quartz glass outer face with a moist
cloth. Check the quartz glass for damage prior to refitting. Refit the O ring on the quartz glass, insert the quartz glass in
the unit head against the stop. Press the O ring into the gap between unit head and quartz glass. The O ring will be
pressed into its correct final position by the action of the clamping screw. Screw in the clamping screw clockwise (H)
against the stop. Slide the cleaning rotor onto the quartz glass. Check the O ring at the unit head for damage and
correct seating. Ensure that the O ring is seated in front of the recess at the unit head (I). Carefully push the unit head
into the housing. During this action, the cleaning rotor and the quartzglass are pushed into the rear mounting inside the
housing. The inner marking at the unit head must coincide with the marking (G) on the housing. Carefully push the unit
head into the housing up against the stop.
Note: If the unit head cannot be completely pushed on, check that the clamping screw is fully screwed in against the
stop. Turn the unit head opposite to the arrow direction against the stop while exerting slight pressure (markings on the
unit head and the housing are aligned). Ensure that the safety engagement lever engages. Start up the pump first, then
connect the power supply.
