A high-quality surface well for embedding in the pool wall. Includes inlet nozzles, seals, suction adapter and surface well basket. Used when a steel-walled swimming pool is connected to a sand filter system. Surface well opening: 14.6 x 14.1 cm. Suitable for Kreta Family pools. Pool hoses and tensioners are purchased separately. We recommend the use of filter bags (item 1549, accessory) in the cleaner, which effectively collect the debris. A shut-off valve with a thread and a hose connection (item 1555, accessory) should be installed on the outlet and return valves of the surface cleaner.
