Fitting / Installation
The arrow on the valve housing indicates the direction of the flow.
KV = incoming cold water
VV = incoming hot water
BV = outgoing warm water
Female connections G½ are designed for LK Armatur’s system with o-ring seals, When connecting to this system tighten first by hand until stop, then another 0,5-1,5 turns with an appropriate tool into right position. Other articles are fitted in the usual manner.
The valve has compression fittings for fitting to copper or steel pipes. When fitted to a male thread connection, adapter LK 373 15 x G½ art.no 189 8022 (560), or LK 373 22 x G¾ art.no 189 8055 (548) is used.
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. Soft pipes are to be fitted with a support sleeve.
Operation and maintenance
The combination valve requires no maintenance. The installation should be checked regularly.
The valve knob is used to set the desired warm water temperature within the range 38°C to 65°C.
