Filter installation kit for use with such as an air condensing unit
A retrofit installation kit for use with such as an exteriorly located air conditioner condensing unit. The kit includes a flexible filtration screen and a set of customized fasteners which substitute for existing fasteners used to hold together the outer sheathing of the unit frame. The substitution of fasteners for the typical mounting screws utilized in the original unit construction precludes the possibility of such as damaging the unit due to drilling new fastener holes, this running the risk of rupturing fluid coils within the unit, or damaging other sensitive electrical or mechanical components.
