LK 505 AquaNodeLK 505 AquaNode
LK 505 AquaNode 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.
