Section Code 2390 : Dish. Washing machines in this section will indicate the category of backflow prevention built into each appliance. The location and the use of the washing machine will determine any additional backflow protection that may be required.
Back To Directory SectionsRange of under counter and hood type dishwashing machines with flow controlled by solenoid valve and discharged via a type `AB` airgap (verified by test - suitable for backflow protection against fluid category 5). There is a double check valve supplied with every machine. Some models are available with AirConcept and GiO-Module options. Maximum working pressure 5.0 Bar. Models incorporating AirConcept & GiO-Module are cold water use only. All other models have a maximum operating temperature 60°C. Modification November 2019 Supplied with Airbreak to drain.
Range of conveyor type commercial dishwashing machines. Flow is controlled via solenoid valve and discharges via a type `AB` airgap (verified by test - suitable for backflow protection against fluid category 5). The product incorporates a nylon bodied inline strainer with a stainless steel screen as the inlet to the machine. Maximum working pressure 4.0 bar. Maximum operating temperature 60°C
Range of commercial dishwashers, glass washers and washer disinfectors, with solenoid valves incorporating a plastic strainer and plastic flow regulator controlling the flow and discharging via a type `AB` airgap (verified by test - suitable for backflow protection against fluid category 5), one on the cold water supply and hot water supply lines to the washing system and another as part of the steam condenser circuit (applicable models). The appliances are available with or without a water softener (ion exchange), steam condenser and additional water supply. The products are supplied with ¾” BSP (F) x ¾” BSP (M) double check valve assemblies (suitable for backflow protection against Fluid Category 3) for installation on each inlet and optional ¾” BSP (M) x ¾” BSP (F) in-line strainers (incorporating a stainless steel mesh) to be installed after the double check valve assembly. Models with a steam condenser circuit include a ‘Y’-piece connector ¾” BSP (F) inlet x ¾” BSP (M) outlets to install after the double check valve or filter (if fitted) prior to the inlet hoses. Maximum working pressure 10.0 Bar. Maximum operating temperature of product and hot supply 60°C. All other inlets are cold supply only.
Range of pass through commercial dishwashing machines (with a water softener - RA models, or without - R models). Flow is controlled by a solenoid valve, which incorporates a flow restrictor and a strainer, and discharges via a type `AB` airgap (verified by test - suitable for backflow protection against fluid category 5). . The water softener (where fitted) is located downstream of the ‘AB’ air gap. The product is supplied with a grey nylon braided EPDM lined flexible hose assembly with ¾” captive nut end connections incorporating EPDM washers. Maximum working pressure 4.0 bar. Maximum operating temperature 60°C.
