Oase Vitronic series Gebrauchsanweisung Seite 7

Attention! Dangerous ultra-violet radiation.
The radiation of the UVC lamp, even in small doses, is dangerous for eyes and skin! Never operate the UVC lamp in a
defective housing or outside of the housing.
Assembly and installation (Figures A-J)
Opening the unit (Figure A): In the housing (1), the unit head (2) is fastened by means of a bayonet closure. Press on
the engagement lug at the housing (1), turn the unit head (2) counter-clockwise and carefully pull it out of the housing
(1).
Installation (Figure B): Place the unit horizontally with its feet down, and fasten with two screws. Other installation
positions are not permissible! Position the unit at a minimum distance of 2m from the pond edge to exclude flooding
and such that it is not exposed to direct sunlight.
Connecting the unit (figures C,D): Oase recommends hoses suitable for a minimum pressure of 1 bar. Cut the stepped
hose connectors (4) to suit the hose diameter. Slide the union nut over the stepped hose connector (4), fit the hose on
the stepped hose connector (4) and secure with the hose clip (5). Insert the flat seals in the union nut, screw the
stepped hose adapters (4) to the inlet (13) and outlet (12), and screw hand-tight. If necessary, you can change over the
inspection window (3) and the supply hose at the two inlets (13).
Inserting the UVC lamp (Figures F-J): Loosen the self-tapping screw (7) until the the screw tip is concealed by the
clamping screw (8). Unscrew the clamping screw (8) counter-clockwise. Pull off the quartz glass (9) including the O
ring by exerting a slight rotary movement. Insert the supplied UVC lamp (10) in the socket at the unit head (2). Insert
the quartz glass (10) including the O ring (14) against the stop in the unit head (2). Tighten the clamping screw (8)
clockwise up to the stop. Tighten the self-tapping screw (7). Note: A safety switch prevents switching on the UVC lamp
as long as the housing is removed.
Unit assembly (E): Check the O ring (6) at the unit head (2) for correct seating. Carefully push the unit head (2) into the
housing (1) up to the stop while applying slight pressure. While doing so, slightly turn the unit head (2) to ensure that
the tenons and the grooves of the bayonet closure intermesh. Turn the unit head (2) clockwise up to the stop.
Switching on, switching off (Figure K)
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures: Disconnect the power plug (11) prior to reaching into the water and commencing
work.
The unit switches on automatically when power connection is established. Note: Switch the pump on first, then the
UVC clarifying unit.
Switching on: Plug the power plug (11) into the socket. Whether or not the UVC lamp is lit can be checked through
the inspection window (3). Check all connections for leaks.
Switching off: Disconnect the power plug (11).
Cleaning and changing the UVC lamp (Figures A, E-J)
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures: Disconnect the power plug (Figure K, 11) prior to reaching into the water and
