The valve must not be used for steam. The outlet is fitted with compression fitting for simple installation of a discharge pipe.\u003c\/p\u003e\n\u003cp\u003eThe safety relief valve can be installed horizontally or vertically, i.e. with the valve knob facing outwards or upwards. In horizontal installations the outlet must be positioned so that a water pocket cannot be formed.\u003cbr\u003eThe thread has to be sealed in the usual manner.\u003cbr\u003e\u003cbr\u003eIt is easier to fit the compression fitting if a lubricant is applied to the thread and bevel. Tighten first by hand and then with a box spanner. Number of turns to be tightened with a spanner: See the separate datasheet for compression fittings. Soft pipes are to be fitted with a support sleeve.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe safety relief valve requires no maintenance. The opening function should, however, be checked 2-3 times a year.:\u003cbr\u003e\u003cbr\u003eTurn the knob counter clockwise by hand, until water flows out. Let the water flush through for a moment. Then turn the knob until a click is heard, about ¼ turn, and the valve returns to closed position.\u003cbr\u003e\u003cbr\u003eThe safety relief valve may open after a large discharge from the water heater. This is a normal function since the pressure relief level in the water heater can be reached due to the increased volume of the water when heated.\u003c\/p\u003e","brand":"LK","offers":[{"title":"090040 - DIM F ¾\" x 22mm Opening Pressure 0.15 MPa - Discharge Capacity 2962 l\/h","offer_id":55179957010808,"sku":"090040","price":44.95,"currency_code":"EUR","in_stock":true},{"title":"090047 - DIM M ¾\" x 22mm Opening Pressure 0.2 MPa - Discharge Capacity 3298 l\/h","offer_id":55179957043576,"sku":"090047","price":46.95,"currency_code":"EUR","in_stock":true},{"title":"090041 - DIM M ¾\" x 22mm Opening Pressure 0.25 MPa - Discharge Capacity 3602 l\/h","offer_id":55179957076344,"sku":"090041","price":44.95,"currency_code":"EUR","in_stock":true},{"title":"090048 - DIM M ¾\" x 22mm Opening Pressure 0.3 MPa - Discharge Capacity 3883 l\/h","offer_id":55179957109112,"sku":"090048","price":46.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/5523\/1002\/files\/lk-511-varme-klamring_utv.jpg?v=1751023291","url":"https:\/\/heatpumpparts.eu\/products\/lk-511-multisafe-male-thread-compression-fitting-heating","provider":"Heat Pump Parts","version":"1.0","type":"link"}
