Detailed Information

Description

LK 508 HydroFill is a combination valve for hot water heaters. The valve housing has a shut-off to incoming cold water and an integrated non-return valve to prevent flowback of hot water to incoming cold water pipes. The valve housing has two connections with internal thread G ½” for installation of safety, vacuum or filler valves.
Arrows on the valve body indicate the direction of flow.

Female threads are designed for the LK Armaturs system med O-ring seal. Other components are fitted in the usual way. When fitting to a male thread connection, adapter LK 373 is used - see under Accessories.
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 separate data sheet for compression fittings. Soft pipes are to be fitted with a support sleeve.

The valve requires no maintenance. The installation should be checked regularly.
