It is important to note that there are factors that affect how you select the right size of UV for your pool.
Your UV will keep your pool clear of green water up to its maximum capacity as stated above along with an appropriate sanitiser.
The UV range is an effective unit and has multiple uses. It can be used on large pools, aquaculture and other installations, please contact your local dealer for further details.

INSTALLING THE QUARTZ SLEEVE

1. Starting at one end of the unit, unscrew the black end cap (B). You will notice that this black end cap houses the bulb socket (F).
2. Unscrew the white locking nut (H) from the same end.
3. Repeat steps 1 and 2 at the other end of the unit.
4. Take the quartz sleeve (D) from the packaging box and slide it through the UV until it finds the hole at the far end of the unit.
5. Take the quartz sleeve O-Ring (G) and fit it around one end of the quartz sleeve.
6. Slide this quartz sleeve O-Ring (G) towards the thread on the UV body, ensuring that equal amounts of quartz sleeve are visible at each end of the unit.
7. Fit the quartz sleeve O-Ring (G) at the other end of the quartz sleeve, again ensuring that equal amounts of quartz sleeve are visible at each end of the unit. IMPORTANT: Ensure that equal amounts of the quartz sleeve are visible at each end of the unit before fitting the locking nuts.
8. Now screw the white locking nut (H) back into position.
9. Ensure the locking nut is HAND TIGHTENED to prevent causing damage to the O-Ring. No tools are needed.
10. Repeat steps 8 and 9 at the other end of the unit.
11. The quartz sleeve is now in position ready to take the UV bulb.
12. Run for 24 hours to check the installation is correct with no leaks. See page 12 for details. Re-install if any leaks are detected – if no leaks proceed to lamp installation.
    HAND TIGHTEN FITTINGS ONLY – DO NOT USE TOOLS

POSITIONING AND MOUNTING THE UV

Fitting mounting brackets (15W to 75W)
Stainless steel brackets and screws can be found in bags inside the packaging.
You will need to install these mounting brackets to the rear of the UV at each end using a 3mm Allen key. HAND TIGHTEN ONLY.

Fitting mounting brackets (110W)
Stainless steel mounting brackets, nuts and bolts can be found inside the packaging.
On the 110 UV, you can find the two mounting brackets inside the cardboard fitting inside the box. Nuts and bolts are packed in a small bag. You will need to install these  mounting brackets to the rear of the UV at each end. Use a 8mm nut runner and spanner. HAND TIGHTEN ONLY.

CONNECTION TO YOUR PIPEWORK

IMPORTANT: Do not overtighten fittings.
Please note that there is no correct direction of flow through the unit, either end of the unit may be used as the inlet or outlet.
IMPORTANT: Valves positioned after the UV must never be closed when the pump is in operation. DO NOT “dead-head” the unit.
All units are fully serviceable without removing the unit therefore they do not need a by-pass to be installed.
INSTALLING A BY-PASS – 110W MODELS
If a by-pass is required, we recommend using a Double Union Ball Valve glued to a length of Pressure Pipe at each end of the UV. This will enable you to isolate the UV during maintenance.

WATER TESTING THE QUARTZ, O-RINGS AND LOCKING NUTS
Now that the unit is in position and connected to pipework, the quartz sleeve and O-ring at each end can be leak tested to ensure that they have been fitted properly. Failure  to test for  leaks and improper installation at this stage may cause water to seep into and damage the bulb socket and end cap flat washer.

STEP 1: Fit quartz sleeve, o-rings and locking nuts. STEP 2: Check the locking nuts are hand tight only. STEP 3: Position and mount UV and connect inlet and outlet connections. STEP 4: Connect up to pipework and turn on pump to start water flow. STEP 5: Check locking nuts for signs of water leaking. STEP 6: If water seeps from locking nuts, check quartz sleeve installation. See Troubleshooting on page 16. STEP 7: If no water leaks, quartz sleeve has been properly installed. Proceed to connecting the UV to the power supply.
WARNING
Failure to test for leaks and improper installation at this stage may cause water to seep into and damage the bulb socket and ballast. Water damage from improper installation  is NOT covered under warranty.

CONNECTION TO THE ELECTRICITY SUPPLY

Electrical installations must be done by a qualified electrician.
The power supply must meet the specifications on the product.
The cores in the supply cable are coloured in accordance with the following code:

UK / EU:
Brown = Live
Blue = Neutral
Green / Yellow = Earth| USA WIRING
Black = Live

3. While holding one of the black end caps (B) gently push the cable through the end cap which will make it easier to fit the bulb socket (F) in step 5.
   IMPORTANT: Do not pull the cable by holding just the bulb socket.

4. Fit the End Cap Flat Washer (I) over the bulb socket and locate it in the end cap so it is seated on the inside lip of the end cap.
   IMPORTANT: Ensure the end cap flat washer is not twisted and it remains in this location throughout the installation.

5. In no particular order, align the UV bulb pins with the holes in the bulb socket and carefully push the bulb socket firmly onto the UV bulb pins. You may need to hold  the other end of the UV bulb to help you fit the socket.

6. Ensure the UV bulb socket is firmly connected to the UV bulb.

7. Repeat steps 3 to 6 at the other end of the unit.

8. Now at one end of the unit, slide the black end cap (checking that the flat washer in position) over the bulb socket while carefully holding the cable to prevent the bulb  connector disconnecting from the UV bulb.

9. Screw this end cap onto the thread on the white locking nut (H) already connected to the UV body. HAND TIGHTEN ONLY.

10. Repeat steps 8 and 9 at the other end of the unit.

11. Check that all of the fittings are hand tightened. No tools are needed.

12. On multiple bulb units, do not mix up the bulb connectors as this will result in the bulb not illuminating.
    Please ensure that there is enough space at one end of the UV to enable bulb / quartz sleeve removal and maintenance.

UV BULB REPLACEMENT

ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLY BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.

TO REMOVE A UV BULB:
It is not necessary to stop the water circulating through the UV to change the bulb.

1. Disconnect the electricity supply.

2. Unscrew the black end cap at one end of the unit. Take care not to unscrew the white locking nut also.

3. Carefully slide the black end cap over the wire to reveal the bulb socket.
   Take care not to lose the end cap flat washer.

4. Disconnect the bulb socket.

5. Repeat steps 2 to 4 at the other end of the UV.

6. With the end caps out of the way, carefully slide out the UV bulb.

WARNING: If the end caps / electrical connections get wet during this procedure, please ensure that they are thoroughly dried before re-connecting.
TO INSTALL A NEW UV BULB:
Follow the instructions on page 14 to fit a new UV bulb.
IMPORTANT: After checking all the fittings are correctly tightened you can switch your unit back on.

As already mentioned, it is essential that the unit is protected from frost during the winter months, or disconnected from water and electricity supplies and stored indoors.  During the spring and summer season, the quartz sleeve, which separates the UV bulb from the water passing through the unit, will need to be cleaned two or three times.  This is essential, as dirt or limescale building up on the quartz sleeve will inhibit the penetration of the ultraviolet light into the water and affect the efficient working of the unit.

REPLACING / CLEANING QUARTZ SLEEVE

DANGER: ULTRAVIOLET RADIATION. Disconnect Power Before Replacing Lamp ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER  SUPPLY BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.

TO REMOVE A QUARTZ SLEEVE:
PLEASE NOTE: Removing the quartz sleeve will cause water to flow out of the unit.
Flow can be directed to the bypass using the installed bypass. If no bypass is installed then the pump should be turned off and other valves used to isolate the UV.

1. Remove the UV bulb as described on page 15.
2. With the electricity supply disconnected, UV isolated and UV Bulb removed, unscrew the locking nut at one end of the UV.
3. Carefully remove the quartz sleeve O-Ring and keep safe.
4. Unscrew the locking nut from the other end and remove the quartz sleeve O-Ring and keep safe.
5. Carefully remove the quartz sleeve taking care not to allow it to drop inside the UV body.
6. To drain any water that may be left in the unit, we would recommend that you unscrew the mounting bracket(s), disconnect the unit from the pipework, and tilt the unit  to drain the chamber of water.
7. Clean the sleeve and polish with a soft cloth or paper towel. If you live in a hard water area, you may get limescale on the quartz sleeve; this can be easily removed by  using vinegar or a cold water descale.
   WARNING: If the end caps / electrical connections get wet during this procedure, please ensure that they are thoroughly dried before re-connecting.

TO RE-INSTALL A QUARTZ SLEEVE:
Follow the instructions on pages 9 and 12 to re-install the quartz sleeve and UV bulb.
IMPORTANT: After checking all the fittings are correctly tightened you can switch your unit back on.
TROUBLESHOOTING (Also see page 18)
During this procedure or if you notice water leaking from around the end caps you should check the following:

1. Check the O-Ring is undamaged.
2. Check there are no cracks and breaks in the quartz sleeve.
3. Check that the locking nut is compressing the O-Ring to form a water tight seal.
4. Check that the end caps are sufficiently tight.
5. All components are clean and free from dirt and debris.
   *Please note that service items are not subject to a claim under warranty. The service items listed on pages 4 to 7 are available from your Certain dealer.

Spare electrical boxes are available from your Certain dealer.
Use the installation instructions provided with the spare part to install the unit.

IN BUILT PROTECTION

The CUV range of UV disinfection system sterilisers have thermal overload protection which automatically shuts down and then enables a fast re-start when the problem has been cleared. This may be as a result of water in the end caps. Please see the troubleshooting section.
Thermal Overload Protection
This will automatically switch off the unit should the temperature exceed the maximum operating temperature limits.
Automatic start up and shut down protection –
This protects the electrical components in the event of a power surge.

TROUBLE SHOOTING

If the UV bulb is not lit, then you need to investigate the power to your unit.

• Has your RCD tripped? If yes, check your wiring and reset.
• Examine the UV bulb for signs of failure, and replace if necessary.
• Is the UV bulb fitted correctly? Unscrew the end caps and ensure correct fitting as per the instructions as described in this manual.
• Are the end caps dry? If not, allow to dry thoroughly. We recommend the use of a hairdryer for this.
• UV units with multiple bulbs are electrically linked as a pair. Therefore if one bulb fails, both bulbs will not illuminate. Substituting either bulb will identify which  bulb  has failed.
• Do not mix up the bulb connectors as this will result in the bulb not illuminating.

The unit worked well when I first installed it but recently my pool has gradually gone green again – what is wrong?
Quartz sleeve may have become dirty and requires cleaning. Also make sure you have the right model for your pool size. Ensure your pool filtration is removing waste and  debris efficiently. Dirt in pools will affect the efficiency of the UV. Check that your pool water volume is pumping through the UV every 4 to 8 hours.
Check chemical levels and ensure they are within industry standards.
Only after you have carried out these checks should you contact your Certain dealer, who will then be able to advise you further.

The unit appears to be leaking from the end fittings?
This could possibly be caused by an incorrectly fitted, damaged or overtightened O-Ring on the quartz sleeve. Please check the quartz sleeve O-Ring, reposition it or if  necessary replace it with a new one. Follow the steps on page 12 to test.
IMPORTANT: Do not fit the bulb socket or end cap until the issue is solved.
If water enters the bulb socket it can cause irreparable damage to bulb socket and ballast.
Damage caused by improper fitting of the quartz sleeve, o-rings and locking nuts are not covered under warranty.
