Thinking about installing a Blueridge ductless mini-split? Many of our customers choose to do the majority (90%) of the installation themselves and then hire a pro for the final start-up. Our DIY mini-splits allow customers to complete 100% of the installation on their own.
In this article, Alpine’s HVAC experts explain the process of installing a mini-split system with wall-mounted air handler in four easy steps:
1 Mount
- Outside: Install the condenser on a pad or bracket and in a convenient location.
- Inside: Attach the included mounting plate on the wall where you want to install the air handler.
- Using a hole saw, drill through your wall at a slight downward angle, adjacent to the lower right-hand side of the mounting plate. Insert wall sleeve, if desired.
- Hang the indoor unit on the mounting plate while running the refrigerant lines, wiring, and drain tubing through the hole to the outside.
2 Connect
- Using a torque wrench, secure the refrigerant lines to the connectors on the indoor unit and then the outdoor unit.
- Connect the wiring between indoor and outdoor units. Make sure to match each color of wire to the corresponding terminal.
- Discharge the condensate line away from the wall and to the outside.
3 Electrical
We recommend hiring an electrician for this portion of the job if you are not trained to work with high voltage electricity.
- Turn off power at the breaker box.
- Depending on your particular model, run 220- or 110-volt power from a dedicated circuit on your breaker panel to a disconnect box located near the outdoor unit.
- Install an electrical whip (weatherproof power wiring) connecting the disconnect box to the outdoor unit.
- Turn the power back on at breaker box.
4 Start-Up
A. Conventional Mini-Split: Hire a Pro
Your HVAC contractor will:
- Do a pressure test to check for leaks
- Pull a vacuum on the refrigerant lines
- Release the refrigerant from the condenser into the system
- Add refrigerant if the refrigerant lines are longer than the factory precharge in the system
- Startup and test the system
B. DIY Mini-Split: Self Start-Up
- Release the refrigerant from the outdoor unit into the system using an Allen wrench.
- Check for leaks: Use a spray bottle with soapy water where the line sets connect.
- If there are leaks, retighten the line set connections to the proper torque.
- Turn on the system.
