This is a do-it-yourself recharge kit for R410A mini-split systems. It bundles a charging gauge, an adapter, and a can of R410A that carries UV dye and leak sealant, so one can tops up refrigerant and marks leaks for later detection. The kit suits homeowners with a small mini-split who want to try a top-up before calling a technician, though US EPA Section 608 rules require an certified technician to add or remove refrigerant. Compared with plain refrigerant cans, it adds the gauge and the dye-and-sealant mix, but it is not a repair for a confirmed leak and cannot match a technician's evacuation and pressure testing.

This kit is for recharging a mini-split air conditioner with R410A refrigerant. It is a do-it-yourself style recharge kit that includes the refrigerant, a charging gauge and an adapter.
The refrigerant has UV dye and sealant mixed in, so the kit combines recharging, leak detection and sealing in one product.
Always charge in cooling mode, no matter the outside or inside temperature. Set the unit to 62 degrees. Recharging in heat mode involves high pressure and is dangerous.
