Installation Kits Cooper hunter

A typical install kit includes pre-flared copper line sets (with insulation), a drain hose, communication wire, mounting brackets or wall sleeve, and wrap or sealant tape. Many kits also bundle wall sleeves, torque bands, and line set covers to streamline installation and protect your system long-term.

Some systems—like Quick-Connect or precharged units—include basic kits. However, most mini splits sold online require a separate install kit, especially if you're customizing line set length or need code-required accessories like a fused disconnect box or surge protector.

Pro installers often use vacuum pumps, micron gauges, core removal tools, torque wrenches, and nitrogen tanks to pressure test and seal systems correctly. For code compliance, many also add a weatherproof disconnect box and surge protection near the outdoor unit.
