¶ 0,5 m/s. Hair entrapment tests shall be performed on suction devices according to 5.3. Safety requirements a) to c) are not applicable to: — skimmers, because they are vented (see 4.4.3) and partly above the water level; — integrated swim jet systems, because the users are pushed away from the outlet, as defined in 3.3 by the action of the inlet. Additionally at least one of the following requirements shall be met: a) multiple suction outlet system designed in such a way that: 1) a minimum of two balanced and functioning suction outlets; 2) the distance between the nearest points of the perimeters of the devices shall be as large as possible with respect to the size of the pool and the design of suction outlets, but with a minimum of 1 m to ensure the appropriate level of safety from entrapment; 3) if any one of the suction outlets becomes blocked, the flow through the remaining suction outlet/s shall accommodate 100 % of the flow rate. b) in case of suction outlet systems with only one grille, the grille shall be designed in such a way that, either, 1) one user cannot cover more than 50 % of the opening; or 2) raised grilles domed opposite to the flow direction, with prevalent peripheral suction. The height of the dome shall be at least 10 % of the main dimension; or 3) single grilles with a surface of the area circumscribed to the suction openings

In addition to the requirements in a) to c), a vacuum release system may be provided. When retrofitting existing installations that have a single suction outlet which does not comply with the requirements of this clause, then the following actions are required: SIST EN 16713-2:2016

The number of inlets should be sufficient to take 100 % of the nominal flow rate of filtration system. The water speed at pool inlets shall be
¶ 15 m/s, except for vertical injection from the swimming pool floor in water depth < 700 mm, where it shall be
¶ 2 m/s. The number and location of the inlets shall ensure an equal and efficient water distribution in order to avoid water stagnation taking into account the following: a) effective water volume of the pool and pool size; b) pool shape; c) outlet location; d) nominal flow rate of filtration system. To verify the water distribution the dye test according to 5.1 may be applied if necessary. 4.5.2 Introduction of pool water at reduced filtration flow rate In case of reduced filtration flow rate e.g. during night time when the pool is not used, the introduction of pool water into the pool shall still be sufficient to ensure the maximum turnover time in 4.2. The validation at reduced flow rate may be verified according to 5.1 if necessary. 4.5.3 Air and water operated leisure feature 4.5.3.1 Introduction of water and/or air from the floor Features incorporating the introduction of water and/or air under pressure from the swimming pool floor shall not be installed in depths of less than 700 mm unless: a) the vertical water speed is

Key 1 walkable floor Figure 4 — Fountains — Horizontal and vertical clearances Generally, protruding jets should be avoided on the swimming pool wall, however in the case of overhanging counter-current or filtration units, protruding jets are allowed as long as they are part of a visible obstacle in the pool. 4.5.4 Other dangers The manufacturer shall provide recommendations for maintenance and cleaning of the air and water operated leisure features. 4.6 Pipe work The pipework and fittings used in any circulation system should be sized to take the nominal flow rate of filtration system and to minimize frictional head losses. The material should be non-corroding and in general terms suitable for the head pressure in the system and the water speed should not exceed 3 m/s with in the circulation pipe work at the pressure side. This is a maximum water speed at the pressure side, lower speeds are encouraged and will result in added energy savings. To avoid a potential cavitation risk it is recommended that water speed at the suction side of the pump shall be lower than the water speed at the pressure side taking into account pump suction behaviour and manufacturer's recommendations.
