Manometer-Panel

Product Code: PG-1

Category: Filter

Manometertafel zur Überwachung des Filterdrucks. Wird am Filter oder am Verteiler montiert und zeigt den Betriebsdruck auf einen Blick, sodass erkennbar ist, wann das Sandbett beladen ist und eine Rückspülung fällig wird. Notieren Sie nach jeder Rückspülung den Wert des sauberen Filters; steigt der Zeiger um 0,5–0,7 bar darüber, erneut rückspülen. Ein Wert, der nie ansteigt, deutet auf ein kanalisiertes Sandbett oder ein undichtes Mehrwegeventil hin, während ein Wert, der nach der Rückspülung hoch bleibt, auf verkalkten Sand hinweist, der ersetzt werden muss. Passt auf den Standard-Manometeranschluss der Waterstar Top-Mount- und Side-Mount-Filter.

Frequently asked questions

What do the six positions of the multiport valve do?

Filter (normal running), Backwash (reverses flow to flush the bed to waste), Rinse (re-settles the bed for 20–30 seconds after a backwash), Waste (drains the pool or vacuums heavy dirt straight to drain, bypassing the filter), Recirculate (circulates without filtering, used when dosing) and Closed. Always stop the pump before moving the handle.

Which multiport valve fits my filter?

MPV-T valves are top-mount, for the Waterstar T-series residential filters; MPV-S valves are side-mount. Both come in 1.5 inch and 2 inch — choose the size of your pump and pipework. All are 6-way with a pressure-gauge port; the MPV-T-15 connects to a 50 mm filter tree.

Which sand grade goes where?

0.4–0.8 mm silica sand (FM-4-8-25) is the filtration layer used in every Waterstar filter. 0.8–1.2 mm (FM-8-12-25) is the intermediate layer specified on some commercial filters between the 1–2 mm gravel support bed and the fine sand. Never substitute building sand — it is neither washed nor graded and will channel.

How often should the sand be replaced?

Every few seasons, or sooner when backwash intervals get shorter, the water stays cloudy after a backwash, or the bed has channelled or formed mud balls. Replace the full charge with the grade on the filter's data sheet and rinse the new bed before the first filter cycle.
