CA 2439700

A filter manifold is provided in a water purification system (20) and includes at least one filter element (28, 30, 32, 34) for producing relatively purified water, wherein the filter manifold incorporates a shut-off valve (24) designed to prevent filter element removal unless the shut-off valve (24) is first switched to a closed position for turning off the incoming water supply. The shut-off valve (24) includes an elongated actuator lever (68) which in a normal open position engages and retains a manifold latch plate (54) in a latched position retaining the at least one filter element (28, 30, 32, 34) in connected relation with flow couplers to produce purified water. Upon movement of the actuator lever (68) to a closed position shutting off the incoming water supply, the manifold latch plate (54) can be unlatched from the at least one filter element (28, 30, 32, 34) to permit filter element removal and replacement.

L'invention concerne un collecteur filtrant utilisé dans un système de purification d'eau (20), comprenant au moins un élément filtrant (28, 30, 32, 34) destiné à produire une eau relativement purifiée. Ce collecteur filtrant comprend une vanne d'arrêt (24) conçue pour empêcher que l'élément filtrant ne soit retiré si la vanne d'arrêt (24) n'est pas mise en position fermée pour couper l'arrivée d'eau. La vanne d'arrêt (24) comprend un levier de commande allongé (68) qui, en position ouverte, est en prise avec une plaque de verrouillage (54) de collecteur et retient cette dernière dans une position verrouillée retenant le ou les éléments filtrants (28, 30, 32, 34) connectés aux raccords pour produire une eau purifiée. Lorsque l'on actionne le levier de commande (68) et qu'on le met en position fermée pour couper l'arrivée d'eau, la plaque de verrouillage (54) du collecteur peut être déverrouillée par rapport auxdits éléments filtrants (28, 30, 32, 34) pour permettre le retrait et le remplacement des éléments filtrants.
