LK 521 MultiFill Combination Valve

LK 521 MultiFill is a compact combination valve for easy filling of brine in the collector hose for ground source heat pumps.

Description

LK 521 MultiFill is a compact combination valve for easy filling of brine in the collector hose for ground source heat pumps. The valve has a filter that protects the evaporator against any particles. In versions G25 and G32, the valve is supplied with insulation to protect against condensation and possible ice formation. In version G50, the valve is supplied without insulation. The valve's compact design makes it easy to install even in tight spaces. LK 521 MultiFill can also be used in other applications that require filling and filtering. Arrows on the valve housing indicate the flow direction. The valve should be insulated with the insulation supplied.

Apart from cleaning the filter, no maintenance is required. Cleaning of the filter should be carried out immediately after installation, after one month and then every two years or when filling the system with liquid. Check the installation regularly.
