| FLEX UV-C/ULTRAFLEX UV-C
Before installing this appartus, please read
the instructions very carefully.
ACTION
The UV-C lamps generate UV-C radiation at a wavelength of 254 nm, which has a
bactericidal action.
• Up to 35% higher UV-C output due to reflection.
• Protects your fish against germs.
• Controls the growth of fungi, bacteria and algae.
• Cleans pond water without the use of chemicals.
• Makes the pond water clear again.
• Safe and good for your fish.
• Flexible connection options.
• Universal connecting pieces included in the package.
• Made in the Netherlands.
This UV-C device ensures a clear pond with healthy fish. The pond water is pumped
through the UV-C device, where it is exposed to UV-C radiation at a wavelength of 254
nanometres. The radiation is produced by a special light, which ensures that germs
and bacteria are not given the opportunity to develop. The water is exposed to an
extra long radiation time, thanks to the length of the device. Furthermore, the housing
reflects the UV-C radiation, which increases efficiency by up to 35%. The housing
of the Flex UV-C has an inlet/outlet for water on 4 sides, enabling you to install the
UV-C device onto your pipe system any way you like. During the frost-free period the
device is used 24 hours a day, so as to achieve an optimal result. Thanks to this UV-C
device your pond water will become clear within 14 days and your fish will be in peak
condition.
EARTHING INSTALLATION (DRAWING 1)
1. Pull the cable (2) through the strain relief (4) before fitting the synthetic strain relief
(4) onto the earth bolt (1). Position the strain relief (4) at approximately 10 cm from
the eye (2) of the earth cable.
2. Place the eye (2) of the cable onto the earth bolt that is fitted to the housing.
3. Then place a toothed lock washer (3).
4. Fit the strain relief (4), creating a loop of Ø5 cm.
5. Finally place the second toothed lock washer (5) and the lock nut (6) onto the earth bolt.
6. Once the parts have been placed onto the earth bolt in the correct sequence, they
can be tightened with a spanner or a ring spanner number 8.
INSTALLATION (DRAWING 2)
This device must never be put in the water. The ideal location to install your device is
immediately behind the filter. See schematic representation in the front of the manual
Always install outside the pond. Ensure that there is always water flowing through the
unit when the lamp is on. Switch the device off when administering medication.
1. Fit the Flex UV-C with the three-piece couplings (I) in the circuit and place the caps
with the nut on the inlets/outlets that are not being used, and tighten them.
2. Fit the unit with the pipe clips (O) (supplied with the set) at a permanent installation
point and tighten the three-piece coupling (I).
3. Fit the lamp (K) in the lamp holder (L); than slide the lamp (K) carefully into the
quartz glass (M) and tighten the screw nut (N) finger-tight on the unit.
4. Start the pump and check the flow of the system and that it is not leaking. Then
check the seals (P) for correct positioning both at the connections and the quartz
glass (see drawing 2).
5. Plug the power lead of the UV-C device into an earthed electrical socket with an
earth leakage switch. Check that the lamp lights up; this can be seen through the
transparent attachments on the device.
6. The device is switched off by removing the plug from the electrical socket.
7. Make sure there is enough room left (+/- 1 mtr.) to remove the lamp (K)/quartz glass
(M) for replacement and/or maintenance.
DISMANTLING/MAINTENANCE (DRAWING 2)
During maintenance/dismantling always disconnect electrical current. The device
needs to be cleaned at least twice a year. If algae or lime scale forms on the quartz
glass tube (M) containing the lamp, it must be cleaned. The special lamp must be
replaced after 9,000 hours. Clean the aluminium interior with a soft brush.
1. Unscrew the three-part couplings (I) and allow the water to flow out of the device.
2. Twist the nut (N) containing the lamp off the device and replace the lamp (K) if
needed. Please handle with care as these are very delicate parts.
3. Carefully remove the quartz glass (M) with a large flat screwdriver (see drawing 3).
Never force it!
4. Clean the quartz glass with an appropriate solution. Always use a soft cloth to
clean the glass to prevent scratches.
5. When replacing the quartz glass in the housing make sure that it is placed on the
seals (P) correctly and carefully slide the end of the quartz glass into the receiving
guide (Q) (see drawing 4).
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.
