Description
LK 534 ThermoFill® EA is a filling valve for heating systems. The valve has an integrated shut-off/check valve which ensures opening even at low pressure differences. The check valve is inspectionable and classified as a back flow preventer Type EA according to EN 1717.
By closing the first valve towards the tap water system and loosening the screw, the function of the check valve can be checked.
The arrow on the valve body indicates the direction of the flow.
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 valve requires no maintenance but the installation should be checked regularly.
