Blue Lagoon UV-C 15.000 Mode D'emploi page 4

Installation of the earth (Drawing 1)
1 Pull the cable (B) through the strain relief (F) before fitting the synthetic strain relief (F) onto the earth bolt (A). Position the strain relief
(F) at approximately 10 cm from the eye (H) of the earth cable (B).
2 Place the eye (H) of the cable (B) onto the earth bolt (A) that is fitted to the housing.
3 Then place a toothed lock washer (C), a hexagon nut (D) and another toothed lock washer (E) on top of the eye (H).
4 Fit the strain relief (F) on top, creating a loop of Ø 5 cm.
5 Finally place the lock nut (G) onto the earth bolt (A).
6 Once the various nuts have been placed onto the earth bolt (A) in the correct sequence, they can be tightened with a spanner or a ring
spanner number 8. Do not tighten too firmly, otherwise you may crack the strain relief. (The transparent nut that was screwed on the earth
bolt (A) on delivery has no further use, and can be discarded).
Installation of the device (Drawing 2)
Determine where the device will be installed. The Blue Lagoon UV-C Tech must never be installed behind the Ph regulator, the heater or the
salt electrolysis system in your swimming pool installation. The ideal location to install your device is immediately behind the filter. The
installation must always take place outside of the pool. Ensure that there is always water flowing through the unit when the lamp is on. Never
install the unit in an area exposed to full sunlight. The installation must always take place in a dry and well-ventilated area. The device must
always be fitted in the vertical position, and a space of 30 cm must be available underneath to carry out maintenance. An area of approx. 1.5
m must be available at the top in order to be able to replace the lamp (K) smoothly without having to dismantle the complete device.
1 Determine where the device will be installed. Make sure to leave a free area (+/- 1 metre) in order to be able to remove the lamp (K) /
quartz glass (M) for the purpose of replacement and/or maintenance.
2 Fit the supplied pipe clips (O) in fixed positions, press the unit into the pipe clips and tighten the three-part coupling (I). Pay hereby
attention to the correct position of the sealing rings (P), both with regard to the connections and the quartz glass (see drawing 2).
3 Fit the unit into the circuit using the three-part couplings (I). The inlet and outlet of the three-part coupling is Ø 63 mm. If your pipes are
smaller than 63 mm, you can use the adapter (Ø 63 x Ø 50 mm) (T). This must be glued onto the three-part coupling (I). On one side of the
adapter (T), there is a screw thread on the inside giving the option of fitting an adapter, with a sealing ring (not included in the delivery),
onto it if necessary. Adapter sets can be obtained from your distributor (article number B290020).
4 Unscrew the screw ring (N) from the housing (U). Remove the UV-C lamp (K) from the supplied case (see packaging) and carefully slide the
lamp into the quartz glass (M). Carefully connect the lamp holder (L) to the UV-C lamp (K) and then screw the screw ring (N) hand-tight
onto the housing (U).
5 Activate the pump and check the flow and any leakage of the system.
6 Put the plug of the UV-C device in a wall socket with a safety ground and fitted with a residual current circuit-breaker. Check whether the
lamp is operating by looking through the transparent components of the unit. The unit is switched off by pulling the plug out of the socket
Dismantling / Maintenance
Always switch off the power supply during maintenance/dismantling of the device.
The device must be cleaned twice a year. If there is an increase in algae and/or scale, the quartz glass tube (M) in which the lamp is positioned
must be cleaned. The special lamp must be replaced after 4,500 operating hours. The stainless steel interior can be cleaned with a soft brush.
1 Drain the water from the device.
2 Unscrew the screw cap (N) and disconnect the lamp (K) from the lamp holder (L). Remove the lamp from the quartz glass and, if necessary,
replace the special lamp (K). As these parts are very fragile, caution is essential.
3 Carefully remove the quartz glass (M) (see drawing 3). Never use force!
4 Clean the quartz glass with a suitable agent. Always use a soft cloth to clean the glass in order to prevent scratches.
5 Carefully replace the lamp in the quartz glass, put the O-ring (T) back on the quartz glass and connect the lamp (K) to the lamp holder (L).
Screw the screw cap (N) onto the housing again.
If the housing or the electrical section must be replaced then the earthing should first be disconnected from the housing.
When assembling a new housing or electrical section then please read Installation and Dismantling first. Make sure that you keep the various
bits of the earthing properly. These are not supplied with a new housing or electrical section. If there is any doubt about the connection,
consult a certified electrician.
