Isolation valves allow for the maintenance of the heat pump without the need to drain the entire hydraulic circuit.
Where are they installed?
They are usually provided on the supply and return lines, near the unit and critical components.
Fittings and disassembly
Appropriate disconnections facilitate the replacement of filters, circulators, or other components.
Caution
Their position must allow easy access and must not restrict the required flow cross-section.
