Insulation panel assembly for a refrigeration unit
An insulation panel assembly for a refrigeration unit includes a first panel, a second panel coupled to the first panel, an evacuation hub defining an evacuation port that extends from an inlet to an outlet and a groove that extends around the inlet, and a conduit engaged with the evacuation hub. The second panel defines an aperture and includes a protruding surround that extends around the aperture. The evacuation hub is positioned such that the inlet is aligned with the aperture defined by the second panel and the groove receives the protruding surround of the second panel therein. Further, the conduit extends into the evacuation port via the outlet.
