Maintenance And Care - JBL PROCRISTAL UV-C Compact 5W Handbuch

 Hose installation and putting the device into operation
Push the hoses onto the stepped hose tails and secure them with suitable hose clips. Put the
pump into operation and check that the appliance is watertight. Cut the hoses and lay them as
short as possible to avoid unnecessary bends.
Connect the JBL PROCRISTALL UV-C Water Clarifier to the mains. If the water clarifier is functioning
correctly, a blue LED light goes on at the electrical unit (2 a). If not, please check the correct con-
nection between bulb and socket (see chapter maintenance and care).
IMPORTANT: To ensure a long and trouble-free operation please make sure to allow air to
completely escape from the device during the starting-up and after operating pauses.

Maintenance and care

Before working on the device or in the aquarium/pond disconnect all electrical appliances
in the aquarium/pond from the mains. The plug should never be pulled out of the socket by
the cable. Always hold the plug when disconnecting.
Deposits (dirt, limescale etc.) inside the casing prevent the optimum efficacy of the UVC water
clarifier. Therefore the appliance should be cleaned inside about twice a year (more frequently if
performance significantly deteriorates). The UVC lamp should be replaced once a year in the early
spring (when operating in garden ponds) or after max. 6000-8000 operating hours.
 Cleaning
Loosen the hoses and let the water run out of the appliance. Unscrew the upper part of the holder
(1a) and remove the device from the holder (1).
Push the red lock at the electrical unit (2) on position „Open". Open the bayonet catch at the cas-
ing (5) by a short anticlockwise turn and remove the electrical unit with the bulb and quartz glass
cylinder in a longitudinal direction. After a longer operating period it can happen that the lubri-
cant at the O-ring (2 b) has dried out and that more effort is needed to turn it.
Clean the inner surface of the casing (5) with water and a microfibre cloth (JBL WishWash). Lime-
scale deposits can be easily removed after soaking for a short time in JBL Clean A. Make sure not
to damage the inner glass sleeve inside the casing. Clean the outside of the quartz glass cylinder
(4) in the same way.
.If the bulb does not need to be replaced grease the O-ring (2) at the electrical unit (2) with com-
mercially available petroleum jelly (Vaseline) and re-connect the electrical unit to the casing by
turning it clockwise.
Push the red lock to the „Close" position.
Return the device to its previous position and put it into operation as described in point 2) and 3).
 Replacing the bulb
Open the device as described in point 4).
Loosen the locking screw (4 c) at the union nut (4b) of the quartz glass cylinder (4) and open the
union nut.
