MRCOOL 35' Line Set Extension Kit for DIY Mini Split Systems

When installing your MRCOOL Mini Split System at a distance greater than the standard 25 feet, this extension kit provides everything you need to extend the line set for longer installations. Perfect for setups requiring up to 75 feet between the air handler and condenser, this kit includes a 35-foot pre-charged line set, couplers, and an extended control cable to ensure a smooth, efficient installation.

Key Features:

  • 35' Pre-Charged Line Set: Extends your system's line set beyond the standard 25 feet.
  • Couplers Included: The kit comes with DIYCOUPLER-38 and DIYCOUPLER-58 to seamlessly connect the additional line set to the existing one, ensuring a secure and leak-free extension.
  • 75' MC5 Pro Cable: Provides a continuous electrical connection between the indoor and outdoor units, replacing the pre-attached 25-foot wire.

Installation Process:

  1. Remove the Pre-Attached Cable: Disconnect the 25-foot control cable or wire pre-installed on your indoor unit.
  2. Install the 75' Cable: Replace it with the new 75-foot MC5 Pro cable provided in the kit for uninterrupted power and control.
  3. Connect Line Sets: Use the included couplers to join the 35-foot line set with your existing 25-foot line, extending the total reach to 75 feet.

Important Considerations:

  • Maximum Length: For optimal performance, the total length of the line set per zone should not exceed 75 feet, measured from the air handler to the condenser.
  • Handling Excess Cable: If there is any excess cable after installation, it should be coiled—never cut—to maintain system integrity.

Compatibility: This kit is designed for use with 24,000 BTU and 36,000 BTU MRCOOL indoor wall units, making it ideal for larger installations that require extended line set lengths.

Extend your MRCOOL Mini Split System confidently with this 35-foot line set extension kit, ensuring a simple, DIY-friendly setup for longer distance installations.

Very nice at a nice price.
Color: White, Size: 35 Inch, Style: 2 Pack, Color: White, Size: 35 Inch, Style: 2 Pack
Very easy to mount on the wall. Very sturdy with about 10-12 lbs on each shelf. Only took about 15 minutes to hang each one.

Cat playground
Color: Black, Size: 35 Inch, Style: 3 Pack, Color: Black, Size: 35 Inch, Style: 3 Pack
Easy to install. Sturdy enough for 2 large rambunctious kitties to play on and look very nice. I was working on a vertical play space for the cats and since these come in many sizes it worked great. I did add grip tape to some.

Not the best quality
Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack, Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack
The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.

Good size and quality
Easy installation, been up on the wall for several months now and they're exactly what we were looking for. Pretty sturdy, good quality. First order of these came broken but they replaced them no problem.
