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:
- Remove the Pre-Attached Cable: Disconnect the 25-foot control cable or wire pre-installed on your indoor unit.
- Install the 75' Cable: Replace it with the new 75-foot MC5 Pro cable provided in the kit for uninterrupted power and control.
- 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.

Fun Dog Toy
Color: Classic Blue
This toy has been a lot of fun for our dogs. One of my dogs absolutely loves balls and is perfectly content to just carry this around in his mouth. The outer shell feels like a firm foam material. It is durable while still being lightweight enough for the dogs to enjoy.
The ball screws together, but it is designed well enough that you are not constantly worried about it coming apart. You have to intentionally press and twist it to open it, so normal dog play has not caused any issues. Inside is the motorized component, which is easy to turn on and recharge. It offers a few different vibration modes, which keeps things interesting.
The reactions from our dogs have been hilarious. One dog is convinced the ball might be plotting against him and keeps a suspicious distance. Another dog loves it so much that he holds it in his mouth while it vibrates, making his entire head shake. Our third dog plays with it exactly as intended, chasing it around and interacting with it normally.
The motor has enough power to make the ball bounce, roll, and move unpredictably across the floor, which keeps the dogs engaged. It has been a great addition to our toy collection and provides a different kind of enrichment than a standard ball. Overall, the dogs really enjoy it.

A fun toy
Color: Classic Blue
Our Malamute loves this ball. He likes to carry it around with him and let it will out of his grasp and pick it back up.
The outer ball it tough and durable, and so far it has held up well during play.
It does bounces more than rolls I expected a little more movement across the floor in a more rolling fashion... like those weasel balls from the 90s, but tends to hop and bounce in place. It does works best on hard floor where it has enough contact to move around and keep the dog engaged.
To charge you have to unscrew the ball in half to access the motor unit, and there is grease on the motor, so be careful when opening it and handling the internal piece. It is not difficult, but it is a little more complicated than a simple plug-in charging port.
The button on is also super hard to press. I you have to really squeeze it and even use a tool to turn it on. It has 2 modes though it is so hard to press I am not sure which mode I actually turn on.
It so far has been a fun toy for our young dog and has lasted our extreme chewer (only supervised play)
I would recommend if it went on sale.

Works well on hardwood, and my dog is just a coward
Color: Classic Blue
This ball works really well on hardwood floors, rolling and moving around just like it's supposed to, though it struggles on carpet where the resistance seems to bog it down. I expected my dog to be thrilled by it, but instead he was afraid of the thing. In fairness, he's a big scaredy-cat by nature, so that says more about him than the toy. The ball itself feels very tough and well made. If he would actually work up the courage to chew on it, I suspect it would hold up extremely well, and I don't think he'd be able to pop it open on his own either. So it's a solid, durable toy that's earned my confidence, even if it hasn't yet earned my dog's.

Keeps puppy busy .. and busy .. and busy
Color: Classic Blue, Color: Classic Blue
My young Shih Tzu is all about "magic" balls. He seems to know what is in the box before it is even opened. The product page says this ball is not meant for small dogs. Well, my Shih Tzu puppy can't read. He is positively obsessed with HIS newest "smart" toy.
Thankfully, this ball came with a partial charge so Bodhi could begin playing immediately. This toy is an improvement over Bodhi's previous chargeable balls with unpredictable movements. I really like that the power button is on the outside since it makes it easier than taking the halves apart every time. The toy functions on every surface (so far) and it is reasonably quiet. This item is also waterproof so it can be rinsed off easily after use.
Fantastic interactive toy.

pelota interactiva para perros
Color: Classic Blue, Color: Classic Blue
Esta pelota interactiva para perros tiene una idea interesante, ya que se mueve y rebota automáticamente para mantenerlos entretenidos. El material de TPU se siente resistente al tacto y adecuado para uso frecuente. Al encenderla, el movimiento capta la atención y resulta entretenido al inicio. Sin embargo, en superficies duras puede hacer algo de ruido, y el patrón de movimiento puede volverse repetitivo después de un tiempo. Para perros muy activos o mordedores fuertes, es recomendable supervisar el uso. El tamaño es adecuado para perros medianos y grandes, y funciona mejor como complemento ocasional de juego que como juguete principal. Puede ser ruidosa en interiores, Es un juguete interesante para mantener a los perros ocupados por períodos cortos, pero tiene algunas limitaciones. Funciona mejor como opción ocasional que para uso continuo.
