Description

LK 505 HydroFill is a combination valve for water heating. The valve closes the cold water inlet and has an integrated check valve preventing recirculation of warm water into the incoming cold water pipe. The valve has a connection with female thread G ½” for fitting of a safety relief valve, vacuum breaker or filling valve.
Arrows on the valve body indicate the direction of the flow.

Female thread connection G½” is designed for the LK Armatur O-ring seal system. 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 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.
