(P) correctly sitting in its seat. IMPORTANT: Before
applying the lid clamp (O), the lid (G) must be pressed
down until the gap between lid and filter case is
eliminated. The lid clamp must be latched, with the
safety metal lock (Z) inserted correctly inside the latch
slot (Fig. 3). WARNING: Pay attention not to catch your
fingers or the line cord, while latching the lid clamp. A padlock (not included) can
be inserted in the bottom hole of the safety lock (Z) to secure it if necessary.
• The Mode Selector Switch (V) must be set to the "Filtering Mode" position with
the switch pointing at Water Outlet (W). Mode selector (V) must be fully
turned 90°; do not set it at intermediate positions.
• Ensure that all hoses have been securely connected to the unit and placed in their
final position. Ensure that the male section of all Click-Fit couplings is equipped
with the rubber O-Ring (aa).
During normal "Filtering Mode" operation, close the Drain Outlet (T) using
the Click fit Sealing Cap (I). Always ensure that the Click-fit Sealing Cap is
securely locked in place (push button fully up).
CAUTION – Do not operate the UV-C lamp (B) without water flowing
through the unit.
After the above verifications, proceed as follows:
1. Turn on the pump and run the filter for several minutes to check that there are no
water leaks
2. If everything is OK and water regularly flows through the unit, plug the Pressure-
Flo UV-C lamp into the power supply. The UV lamp indicator (R) lights up with a
blue shimmer when the UV-C is operating; this light can be better viewed after
dusk.
Keep the filter working for 24 hours a day and ideally all year round, provided that
there is no frost and water can flow freely through the unit.
BACKWASH-CLEANING SYSTEM
When the foam surface becomes clogged, the Backwash-Cleaning System quickly and
efficiently restores normal filter operation without having to open the unit. Cleaning
should be done at least weekly or whenever the cleaning indicator (U) detects that the
filter is clogged or dirty or when cloudy water comes out of the filter. If the pond is
very dirty and during the first weeks the unit is used, the filter may need more frequent
cleaning. Proceed as follows:
1. Turn off the power to the pond pump.
2. Remove the click-fit Sealing Cap from the Drain Outlet (T). CAUTION: there will be
a small flow of water coming out.
3. Connect a drain hose to the Drain Outlet (T) and ensure that it will expel the dirty
water where desired.
4. Turn the Mode Selector Switch (V) to the Drain Mode position (point selector fully
at drain outlet (T)). A small amount of water may continue to come out of the
Water Outlet (W). This is normal. To avoid this, remove the Universal Click-Fit from
the Water Outlet and connect the Sealing Cap Click-Fit.
5. Turn on the power to the pond pump
6. Slide both cleaning handles (S) up and down. The up-and-down sliding motion
causes the cleaning blades to scrape against the surface of the foam filters,
dislodging debris and suspending it in the outer chamber of the filter, where
water loaded with the suspended debris is forced out of the filter through the
Drain Outlet (T). Proceed for several minutes until you see clear water coming out
through the drain hose.
7. CAUTION – The cleaning system uses pond water. This fact must be considered
when using the cleaning feature. When cleaning is complete, refill the pond to the
desired water level.
8. Turn off the power to the pond pump
9. Turn the Mode Selector Switch (V) to the Filtering Mode position (selector fully
pointing at Water Outlet (W)). The filter is now in normal filtering mode. A flow of
green water coming out for a few seconds is quite normal.
10. Seal the Drain Outlet (T) using the Click-fit Sealing Cap (I). Ensure that it is securely
locked in place (push button fully up). If the filter remains clogged at the end of this
operation, inspect the Cleaning Indicator to see whether it is clean and unimpeded
(refer to Foam and Biological Media Cleaning, point 11, for detailed instructions).
If the Cleaning Indicator continues to signal clogged, perform Foam and Biological
Media Cleaning as explained below.
11. Turn on the power to the pond pump.
If the filter remains clogged at the end of this operation, perform Foam and Biological
Media Cleaning below.
CLEANING AND MAINTENANCE OF THE PRESSURE-FLO FILTER
WARNINGS:
• Do not attempt to open the lid clamp (O) and lift the lid when the pump and the
filter are in operation. The lid clamp latch features a safety metal insert to prevent
accidental opening.
• DO NOT ATTEMPT TO VIEW THE LAMP WHEN LIT! Direct exposure to ultraviolet
light can damage eyes and skin.
• The UV-C lamp (B) and the quartz sleeve (C) are made of glass. Handle all parts
with care.
• Make sure that the internal electrical parts of the appliance are dry before, during
and after the maintenance operations.
• The Mode Selector Switch (V) simply diverts water but does not stop it.

Foam and biological media cleaning
At the start of each season or when the Backwash-Cleaning System does not produce
expected results it will be necessary to thoroughly wash or replace the foam filters
Z
(M). During the hot summer months, more frequent cleaning is required. During this
operation, the biological media can also be cleaned and/or replaced (except Pressure-
Flo 1000/3000 UVC).
1. Switch off the UV-C lamp (B) 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. Slowly lift the Cleaning Handles (S) up to their maximum extension above the filter.
5. Remove the safety insert from the metallic lid clamp (O). Unlatch the metallic lid
clamp.
6. Remove the Lid (G) by grasping the cleaning handles or by gently levering into the
side slots by means of an adequate flatheaded screwdriver. CAUTION: do not force
the guiding rods sideways as this may damage the unit.
CAUTION – The lid integrates the UV-C unit with the lamp and the quartz sleeve,
which are made of glass. HANDLE ALL PARTS WITH CARE!
7. You now have access to the Foam Filters (M). Remove all of them together by
grasping and lifting the internal Foam Support Frame (N).
8. Free the Foam Filters (M) from the Foam Support Frame (N) and rinse with pond
water or replace them as required.
9. Rinse the biological media located in the lower section of the Filter Case (Q) with
pond water or replace as required. Pressure-Flo 1000/3000 UVC does not have a
biological media chamber.
10. Clean the Filter Case (Q) with water, particularly around the top edge where the lid
sealing O-ring (P) is seated.
11. If necessary clean the Cleaning Indicator
(U) after disassembling it as follows (the
Mode Selector Switch (V) must be set to
the "Filtering Mode" position): 1) remove
the retaining ring by rotating it counter-
clockwise, 2) remove the indicator and
its spring. Rinse all parts in water and
reassemble them with care (Fig. 4 - Fig. 5).
12. Inspect and clean the two Cleaning Blades
(L) and the guide rods. If necessary, replace
the blades with new ones. Each blade
can easily be detached from the
guiding rod by unscrewing the screw
in the middle.
13. Put the foam and biological filtering
media back in their original locations.
Ensure that the foam filters are properly stacked with no space between them.
14. Reassemble the unit with care. Make sure that the biological filtration media
does not interfere with the foam support frame (N) and that the frame is refitted
correctly.
15. The filter is now ready for start-up. Read and follow all instructions in Filter Start-
up, Operation, and Backwash-Cleaning.
NEVER use soap or detergents for cleaning. Any remaining traces may pollute the
pond and result in damage to sensitive fish tissues.
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. 6) from the filter by unscrewing the 4 screws (J)
that fasten the UV-C head to the filter lid (G). UV-C Head is equipped with anti-loss
