Detailed Information

Description

LK 510/511/512 MultiSafe is a safety relief valve for tap water installations, as well as heating systems with closed boiler system with a power of max.50 kW. The valve must not be used for steam. The outlet is fitted with compression fitting for simple installation of a discharge pipe.

The 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.
The thread has to be sealed in the usual manner.

It 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.

The safety relief valve requires no maintenance. The opening function should, however, be checked 2-3 times a year.:

Turn the knob counterclockwise 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.

The 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.

Questions & Answers

Why is my safety valve leaking?

Is it OK to have water coming out of the wastepipe? When water is heated, it expands and the increased volume needs to go somewhere, meaning that your safety valve will drip.

Can you use LK's safety valves with steam?

None of LK's safety valves are designed to be used with steam.
