Operating Limits and Use Outside Them
| Parameter | Limit | Below | Above |
|---|---|---|---|
| Operating pressure | 0.5 - 8.6 bar | Flow drops; the gasket may not seat fully | Cracking and leaks at bowl and head; fit a pressure reducer |
| Water temperature | 4 - 45 °C | Freezing cracks the bowl; plastic becomes brittle | The bowl softens and deforms; sealing fails |
| Water pH | 6.5 - 9.5 | Acidic water wears gaskets and threads | Scale build-up and early gasket ageing |
Filter Change and Maintenance
- Shut off the mains water.
- Loosen the air vent (plastic plug) to relieve the pressure in the system.
- Remove the bowl with the original wrench, clean it and insert the new filter.
- Check or renew the gasket and grease it with the silicone grease supplied in the box (5-FK-GA-YED-10).
- Fit the bowl to the head and tighten with the wrench; open the water and repeat the air venting.
Gaskets are supplied pre-greased; re-grease them at filter changes. Use PTFE tape only (no hemp or liquid sealant). Check for leaks for the first 48 hours; replace the housing at least every 5 years.
