ALTECH REFILL KIT R25

Description:

The Altech Filling Kit is a compact combination valve for easy filling of refrigerant liquid in the collector hose of ground source heat pumps.

The valve has a filter that protects the evaporator against any particles. The smaller sizes are supplied with insulation to protect against condensation and possible ice formation. The valve's compact design makes it easy to install even in tight spaces. The Altech Filling Kit can also be used in other applications with the need for filling and filtration. Arrows on the valve body indicate flow direction. The valve should be insulated with the supplied insulation. 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.
