LK 556 AntiFreeze

• Protects heating system from freeze damage

• The valve is maintenance free

• Set includes two AntiFreeze valves and two

insulation pieces

LK 556 AntiFreeze protects your heating system, usually in an

air/water heat pump, if the fluid temperature should drop below

+3°C by draining the system. This prevents the heating system

from freezing.

If the valve opens and drains the system, no action is required

to reset the valve, the system can be refilled again as soon as

normal circulation in the heating system is resumed.

Insulation is available as an accessory for maximum energy saving.

Refer to Accessories & Spare parts.
