Changing the UV-C lamp and Cleaning the Quartz Sleeve
Changing the UV-C lamp: to maintain optimum performance, the UV-C lamp (B)
should be replaced every year. An ideal time is Spring, during pre-season
pond maintenance.
Cleaning the Quartz Sleeve: although only filtered water passes through the UVC
section of the Pressure-Flo filter, the quartz sleeve (C) can become coated with
limescale, which will diminish the performance of the UV-C lamp (B). It is
recommended to check and clean the quartz sleeve (C) on a regular basis. The
frequency of cleaning depends on pond conditions.
In order to access the UV-C lamp (B) and the quartz sleeve (C), proceed as follows:
1) Switch off the UV-C lamp by disconnecting the unit plug from the main
power supply.
2) Switch off the pump that supplies the Pressure-Flo Filter.
3) Disconnect all hosing from the unit by releasing the click-fit couplings (push the
"press" button and pull).
4) Remove the UV-C head (A) (Fig. 5) from the filter by unscrewing the 4 screws (J)
that fasten the UV-C head to the filter lid (G).
5) At this stage it is possible to clean the quartz sleeve (C), if required.
Forcleaning the quartz sleeve, simply use a damp soft cloth. In case of
stubborn dirt, some vinegar may be used. Do not use detergents or
other chemical cleaners.
If it is not necessary to change the UV-C lamp, go straight to point #10.

6) To access the UV-C lamp (B), remove the Quartz Sleeve (C) by unscrewing the 2
screws (K) of the Retaining Flange (E) that fasten it to the UV-C head.
7) Pull out the UV-C lamp (B) away from the lamp holder (if it is not the first
start-up) and replace it with a new one. The Lamp holder pins must be correctly
oriented. If the Lamp does not fit at first, rotate it 90°.
WARNING - DO NOT ATTEMPT TO VIEW THE LAMP WHEN LIT!
Direct exposure to ultraviolet light can damage eyes and skin. Do not test
the UV-C lamp unless the filter is fully assembled and closed.
IMPORTANT – Use original Laguna spare parts only. Refer to the Spare Parts List
for correct part number identification.
8) Place the Quartz Sleeve (C) and the two O-rings (D) back in their original position.
IMPORTANT – The Lamp Damper (Y) inside the quartz sleeve must sit between
the lamp and the bottom of the quartz sleeve. Do not remove it.
IMPORTANT – The two O-rings (D) of the quartz sleeve (C) must be
replaced every time the unit is opened.
9) Place the retaining flange (E) in its original position and fasten it with the two
screws (K).
10) Check to ensure that the Quartz Sleeve (C) is not damaged. Check that all the
components are present and have been reassembled properly. If in doubt, consult
your Laguna dealer.

11) Put the UV-C head (A) back on the filter lid (G), ensuring that the inner O-ring (F)
is correctly located before securing the UV-C head with the screws (J).
12) Secure the UV-C head (A) to the filter lid, by refitting and tightening the 4 screws
(J). WARNING – Risk of Electric Shock: Before powering the lamp,
make sure that ALL O-Rings are back in their original position, ALL
screws are tightened and there has not been any damaged to the unit.
Before connecting the unit to the power supply, perform the Filter
Wet Test (see below).
13) The filter is now ready for start-up. Read and follow all instructions in
Filter Start-up, Operation, and Backwash-Cleaning.
Winter Storage
The unit must be protected from frost. In cold winter weather, the unit may be
switched off. It should then be drained of water, removed from its installation and
stored in a dry, weather-proof area. It is recommended to keep the unit lid open
during storage.
Filter Wet Test
Once the unit is fully assembled, it must be wet tested before connecting to the power
supply. This test must be repeated whenever the lamp and the quartz sleeve are
changed or disassembled.
1) Install the filter and connect it to the pump following all installation instructions. Do
NOT switch on the filter. Switch on the pump only and let it run for 24 hours.
2) After 24 hours, switch off the pump and remove the UV-C head (A) from filter by
unscrewing the 4 screws (J). Do not disassemble more parts.
3) Inspect inside the quartz sleeve (C) for leaks. If you see water inside the quartz
sleeve and around the lamp, do NOT connect the unit to power supply but take it to
an authorized Laguna service facility or similar qualified person for verification.
If on the contrary no water is visible inside the quartz sleeve (C), carefully reassemble
the unit and use it normally according to this Installation and Maintenance Guide.
