Picking Up the Equipment

The first phase of the project involves acquiring the right equipment from our trusted supplier, AC Pro. Our shopping list includes a three-ton condenser, two 9,000 BTU fan coils, an 18,000 BTU unit, and all the necessary line sets. Once we’ve got everything we need, it’s time to get started!

Strategizing the Installation

Before jumping into the installation, it’s crucial to have a plan in place. In this procedure, we’ll mount one unit in the living room, with another two units in the bedrooms above their respective closet doors. The arrangement of the line sets will be crucial for optimal performance, so it’s essential to map this out in advance.

The Unboxing Experience

The components of the ductless mini split system might differ slightly from other systems, such as those made by Daikin. For instance, one noticeable distinction is the corrugated copper tubing, which helps prevent kinking. Moreover, the drain hose in our system can be moved to either side as needed.

Mounting the Fan Coils and Wiring

To begin the installation process, we need to mount the fan coils using wall anchors – ideally with two screws landing on a stud for added stability. After mounting the first unit in the living room, we’ll repeat the steps for the bedrooms, ensuring the line sets run through the closets and out to the exterior walls. Moreover, please note that some jurisdictions may require an on/off switch next to the fan coil, so check your local regulations before proceeding.

Connecting the Line Sets and Drains

Seamlessly connecting the various components is imperative for the system’s longevity and functioning. For this mini-split system, we’ll be using a unique line set with pre-attached fittings and corrugated copper tubing. Ensure all connections are secure and that the drain lines are correctly pitched to prevent future issues.

Concealing the Line Sets and Covering the Pipes

A well-executed installation not only ensures the system functions optimally but also looks polished. Hide any exposed pipes, control wiring, and drain hoses using line set covers and stucco patching, ultimately achieving a clean, professional appearance.

Creating a Sturdy Foundation for the Condenser

To avoid damage during heavy rainfall or other adverse conditions, it’s critical to establish an even, stable foundation for the condenser unit. Excavate the soil, fill it with gravel, and then place the condenser pad directly on top. Secure the pad with straps, and use chocks as necessary for stabilization.

Installing Electrical Components and Gutters

To guarantee safety and compliance, carefully install the electrical components, ensuring you achieve specific measurements and bends with the electric wiring. Likewise, for added protection against natural elements, build a shield for the condenser unit, taking care to ensure it is proportional and well-secured.

Lastly, consider adding insulation sleeves around the exposed pipes and appropriate labels to identify the distinct components. This final touch not only fortifies the system but also exemplifies professional workmanship.

Final Thoughts

Installing a three-zone ductless mini split system may be a complex task, but with meticulous planning, high-quality materials, and an eye for detail, it is undoubtedly manageable. With the professional installation guidance provided in this guide, you can be sure that your system will not only function optimally but look fantastic, avoiding unsightly exposed components and cumbersome structures. Remember, always check local regulations for any specific requirements and don’t hesitate to reach out for assistance. Happy installing!
