A blue ridge, ductless mini-split is one of the most efficient ways to heat and cool your home. They’Re, perfect choice for additions, garages or rooms were ductwork is unavailable. Many splits are energy-efficient, quiet and easy to install. The mini split is comprised of two units. The indoor air handler and the outdoor condenser, the components are connected by copper tubing, which allows a necessary refrigerant to circulate a handheld remote gives you thermostatic control over the system before you begin installation make sure you have all the parts you need.
According to the installation manual inspect the various components to ensure there are no defects before installation work begins. You can complete the majority of the installation yourself. However, the last ten percent of the work should be completed by a trained professional. Proper installation is crucial to achieving maximum performance and energy savings. The unit can produce it’s essential to carefully read the Blue Ridge owners manual, paying particular attention to safety precautions and procedures before you start ensure you have the right tools for the job.
Standard tools needed include. The following adjustable wrench, torque, wrench, hex, keys or allen, wrenches, a drill and drill bits, a hole saw a utility knife, a wire cutter and stripper phillips and flat blade screw drivers, a level safety, glasses and work gloves. Your professional installer should bring the rest of the required tools, including manifold gauges, vacuum pump, flaring tool and a dry nitrogen tank with regulator to begin installation choose a spot on the wall surface where you’d, like the unit to be secured location, should be free of obstructions Near the air, inlet and outlet, and should be at least six feet from the floor refer to the manual for more tips on choosing a location. Remove the wall bracket from the back of the mini split indoor air handler hold the bracket in place, use a level to ensure it is horizontally level, then mark the screw holes with a pencil drill. The marked holes to create a pilot hole and use appropriate sized self-tapping screws with anchors to fix the wall mounting frame finally checked to ensure the wall mounting frame is firmly attached.
By pulling on it now, you will create a hole in the wall to allow refrigerant lines, control, wires and condensation drain to go outside the hole is usually two-and-a-half to three inches using a hole saw bit drill the hole making sure to angle downward to the outside. For proper condensate drainage, the wall mounted air handler ships with the refrigerant piping, on the right and the drain tube on the left, but can be configured to your particular application. In this case, we will move the condensate drain tube from the left to the right. This requires removing the outer cover of the air handler open the service hatch and remove the four screws across the front in the fifth screw in the center bottom turn the unit over and release the for locking tabs carefully lift off the cover and turn the unit Over to expose the drain connection, unfasten the retaining clip for the drain hose and remove the drain hose next locate. The rubber drain, plug on the right side, remove it and use it to plug the left side drain, replace the hose on the right side drain and fast in the retaining clip prepared to install the control wire by removing the wire cover and wiring clip push the Color-Coded multi-conductor wire through the inlet hole on the back of the air handler and pull a few inches through the front.
Leave the cover open you’ll, make the wiring connections later now carefully unfold, the refrigerant pipe making sure not to crimp the copper tube in the process. Bundle the control, wire refrigerant lines and drain tubing, together with electrical tape, to make sure it’ll fit easily through the wall and installation support bracket, is an optional tool that helps by acting as a second set of hands holding the air handler in place. While you make the inside connections and prepare to mount the unit, lift the unit into place and carefully past the bundled pipes and wires through the wall opening place. The air handler on the wall mount making sure it is firmly secured and your refrigerant line, condensate tube and electrical cables are completely through the wall. Now you can make the multi-conductor wire connections after cutting the length and stripping the wire make the connections using a screwdriver, replace the wiring clip wiring cover and close the front cover you’re, not ready to install the outdoor heat pump.
Condenser choose the outdoor units location based on your home structure, local codes and convenience of installation. You can place the unit on a pad mounted on an exterior wall using brackets or place it on a rooftop we’re using a pad the simplest and easiest method. The outside unit should be securely mounted, with bolts through the footholds before making any connections with the condenser securely mounted. You can make your outside connections. The air handler unit comes pressurized with nitrogen you’ll hear this harmless gas release.
When you remove the plug, connector flared. Copper ends of the line set to the pipe joint connected to the air handler using the adjustable wrench to hold the piping joint and prevent twisting place. The torque wrench on the Union not and tighten to the setting specified the manual next connect. The drain hose by push-fit and secure with tape, fully been the to bundle to be flush with the wall, making sure not to crimp the copper or drain tubing lines. That covers are an optional accessory that hides the appearance of refrigerant lines and control wires, mount the backing to your exterior wall and once the lines are run snap, the covers in place next remove the panel that covers the refrigerant valves and wiring connections.
Some models may already have the valves exposed, remove the protective screw caps from the valves. Now you can connect the pipe joint of the outdoor unit to the copper line set start. The Union up by hand, then use the torque wrench tightening to the specifications in your manual next connect the multi-conductor wire that has run from the indoor air handler to the Associated terminals on the outdoor unit, double check the color coding to ensure the wires have been Connected correctly, a trained professional is recommended to complete the installation at this point, if the copper pipes are not flare ready or if you wish to call your line set to a shorter lengths, you will need to use a flare tool to create a new flair connection. Use a pipe cutter to cut the copper pipe to the desired length and a shaper to deeper the cut, be sure to put your Union not in place. First then insert the end of the pipe into a flare tool.
Improper flaring is the main reason for refrigerant leaks, refer to your installation manual for more detail and making proper flare connections make sure the flare connection is not tilted. Cracked or otherwise damaged before connecting the refrigerant system must be completely sealed. In order for the system to perform properly start with a pressure test to check for leaks using a yellowjacket adapter will allow you to connect standard service equipment to the mini split service. Ports use dry, nitrogen and pressurize the line set and air handler to 100 to 200 PSIG, then using a soap bubble, solution spray down all of the flare joints and watch for bubbles to appear if bubbles are present, tighten the Union not or, if necessary, reflect the Copper next, the technician will use a vacuum pump, engages to remove all air and moisture prior to releasing refrigerant into the lines after the vacuum is complete. Close the manifold gauge valve use an adjustable wrench to remove the service valve caps and use an Allen, wrench or hex key to fully open both service valves releasing refrigerant into the system.
The condenser requires 220-volt power from a dedicated circuit on your breaker panel, run through an exterior mounted manual disconnect box. A qualified technician should install the circuit, breaker disconnect box and make a high-voltage connection to the condenser, with the refrigerant released and all high and low voltage connections, complete it’s time to power up the system and do the initial startup start the system with the remote and Check for proper operation, congratulations on completing your new installation.
