Frequently Asked Questions - Bitron C 72 OASE

Why is my pond water still green despite using the Bitron C 72?

This can be due to insufficient pump flow, dirty quartz glass, used UVC lamp, or incorrect by-pass setting. Clean the quartz glass, check the flow rate, and adjust the by-pass. Replace the lamp every 8000 hours.

How do I clean the quartz glass of the Bitron C 72?

Disconnect the device and remove the device head. Remove the cleaning rotor and wipe the quartz glass with a damp cloth. Do not use abrasive products. Reassemble the rotor checking its wear.

How often should the UVC lamp be replaced?

The UVC lamp must be replaced after at most 8000 operating hours (about one continuous season). Use only lamps of the same power (72 W) and reference.

How do I adjust the by-pass of the Bitron C 72?

Turn the two rotary handles to adapt the water flow to your pump performance. Optimal adjustment ensures sufficient contact time with UV for maximum clarification.

What should I do if the UVC lamp does not light up?

First check that the power cord is plugged in. If the indicator light remains off, the lamp is likely defective: replace it. Also check the electrical connection and the differential circuit breaker.

The cleaning rotor does not rotate, what should I do?

Check on the operation display if the blue UVC light is flashing. Clean the rotor and the quartz glass. Make sure to use the specific inlet nozzle for flows < 10,000 l/h. If the profile is worn, replace the rotor.

Can I use the Bitron C 72 with salt water?

Yes, but respect the limits: pH 7.5-8.5, temperature between +4 and +25 °C, salt content < 3.5%. Salt water can alter the appearance of the device (outside warranty).

How do I install the Bitron C 72 on an OASE ProfiClear filter?

Insert the outlets with flat gaskets into the tank drillings. For ProfiClear Premium, first screw the adapters, then the 30° inlet elbows. Connect the Bitron to the filter pump via suitable hoses.

What are the important safety instructions?

Use a residual-current circuit breaker of 30 mA. Always disconnect the device before any intervention in the water. Do not allow children to play with the device. Never operate the UVC lamp outside the housing.

Where can I find spare parts for my Bitron C 72?

Original OASE parts (UVC lamp, quartz glass, seals, rotor) are available on www.oase-livingwater.com/piecesdetachees or from an authorized dealer.

Commissioning/start-up

WARNING

Possible death or severe injury from hazardous electrical voltage!

• Prior to reaching into the water, isolate (switch off and disconnect) all units/devices used in the water.
• Isolate the device (disconnect from the power supply) before carrying out any work on it.

NOTE

If the water flow is suddenly interrupted downstream of the outlet (e.g. with a slide valve), this can lead to a brief increase of pressure of more than 1 bar (water hammer). Possible consequences: The unit may be damaged.

• Switching off: First switch off the pump, then close the slide valve. If the unit is operated in a filter system, first take the filter system out of operation.
• Switching on: First open the slide valve, then switch on the pump. If the unit is operated in a filter system, start up the filter system last.
  • Install the slide valve upstream of the inlet.

NOTE

New filters take approx. 3 to 4 weeks before the bacteria in the unit are fully established. During this time – or at a water temperature of <10 ^ – the filter may overflow. In this case the filter does not need to be cleaned.

- When using filter starter, medicines or pond water treatments, leave the UVC clarifying unit switched off for at least 36 hours so as not to impair their efficacy.

Prerequisite

• First switch on the pump, then the UVC clarifier.
• Check all connections for leaks.

Switching ON/switching OFF

• Switching on: Insert the power plug into the socket.
• The unit switches on immediately.
• Switching off: Disconnect the power plug.

Check the function.

□1

• The function display is lit when the UVC lamp is switched on.
• An alternating light/dark blue glow in the inspection window indicates that the cleaning rotor is rotating.

Setting the bypass

The flow rate is controlled by the bypass. Depending on the setting, part of the water flows from the inlet directly out via the opposite outlet. The remaining part of the water is irradiated by the UVC light and flows out via the second outlet. Maximum cleaning capacity is only achieved with an optimum setting.

How to proceed:

□ J

- Set both rotary handles to the delivery rate of the filter pump.
