LK 521 MultiFill® is a combination valve for easy filling of re-

frigerant fluid into ground source heat systems. The valve has a

filter to protect the evaporator against possible grit. Its com-

pact construction allows it to be installed in tight spaces. The

valve comes with an insulation to protect against condensation

and possible icing. LK 521 MultiFill® can also be used in other

applications where filling and filtration are required.

Arrows on the valve body indicate the direction of the flow. The

enclosed insulation should be used. Apart from cleaning the

filter no maintenance is required.
