Exposure to UV radiation can be dangerous to eyes and skin. Do not access lamp when unit is switched on.
Appliance not for persons with reduced capabilities; children must be supervised to ensure they do not play with the appliance.
Disconnect appliances before maintenance. Product is not submersible. Avoid UV exposure through viewing lens.
Use 3-core cable, permanent mains connection in dry enclosure, double pole switched fused spur with 3 or 5 amp fuse.
Position and protect exposed cable runs from damage, especially from gardening tools, lawnmowers, children, or animals.
A 10mA or 30mA Residual Current Circuit Breaker (RCD) MUST be fitted to the mains supply.
The supply cable cannot be replaced. If the cable is damaged, the unit should be discarded.
Installation must conform to national/local wiring regulations. Consult electrician if unsure.
Protect from frost. Drain, remove, and store unit in a dry, frost-protected area if not running year-round.
Minimum 1.2m for Koi. Shallow ponds (<0.75m) add +25% factor due to increased sunlight and warming.
Ponds in full sunshine add +25% factor; shaded ponds are less affected by sunlight.
Northern European: +0%, Southern Europe: +15%, South Africa: +35%. Affects fish activity and feeding.
The pump supplying this unit must not have a maximum head exceeding 6m (8.5 PSI, 0.6 Bar).
Bioforce is pump-fed, pressurised, external filter with integral UVC. Suited for in-ground or above-ground.
Use 20/25mm Cypriflex hose. Connect pump to inlet hosetail, secure with hoseclips. Avoid kinks.
Undo seven securing clips, gently remove lid. Use coin if difficulty arises.
Remove central tube screw, rotate and pull. Remove quartz glass tube similarly.
Push lamp into position with holder accessible. Re-assemble quartz tube and central tube.
Refit lid, ensure seal is clean and free of debris. Re-engage clips, tighten viewing lens.
Connect to mains supply in dry, weatherproof enclosure. Use BROWN (live), BLUE (neutral), GREEN/YELLOW (earth).
Appliance MUST be earthed. Connections must use correct colour code for safety.
Entire pond volume should pass through Bioforce every 1.5-3 hours. Adjust flow if necessary.
Small hose, long runs, high pumping lift reduce output. Choose pump for required flow against full static lift.
Use a pump capable of handling solids. Hozelock Cyprio Aquaforce recommended for ponds in this range.
Fill a known volume container, time it. Calculate flow rate (litres/gallons per hour).
Maintain filtration 24 hours a day during the fish feeding season (water temp above 10°C).
Operating in winter maintains friendly bacteria and helps prevent pond icing.
Supports up to 50cm of fish per 1000 litres (10" per 100 gallons). Introduce fish slowly.
Builds nitrifying bacteria to convert waste. Takes 6-8 weeks. Do not switch UVC on during this period.
Filters are efficient when foam is partly blocked. Cleaning frequency depends on pond dirtiness.
Lift outlet pipe above filter lid before switching off pump. Unscrew viewing lens to relieve siphon lock.
Remove lid, squeeze foam, rinse foams in pond water. Reposition foams flat. Refit lid and clips.
Swap inlet/outlet pipes or connect waste pipe to inlet. Run pump to flush. Ensure return pipe goes to waste.
Normally no need to remove. Remove to access biomedia, ensure it is refitted correctly.
Wipe quartz tube with a soft cloth and cleaning agent (e.g., vinegar) to remove limescale.
Maximum lamp life is 12 months continuous use. Replace lamp after this period, even if still glowing.
Remove, wash, dry unit. Store in a dry, frost-protected area with lid off for ventilation.
12 months. Requires correct installation, operation, equipment size, and contacting help line.
