Mitsubishi HVAC Installation Accessories

Mitsubishi HVAC Installation Accessories are the finishing and support parts that go with a Mitsubishi mini split or heat pump. This collection covers line set cover fittings, wall covers, electrical connectors, relays, drain parts, and outdoor mounting bases. Each part is made to fit Mitsubishi equipment for a clean, matched look.

What Are Mitsubishi HVAC Installation Accessories?

Mitsubishi HVAC Installation Accessories are the smaller parts that complete a Mitsubishi system. The indoor and outdoor units do the heating and cooling. These accessories protect the lines, finish the outside of the home, and connect extra controls.

Think of these mini split accessories as the pieces that turn a working system into a finished one.

These parts pair with Mitsubishi systems like those in the Mitsubishi P-Series Hyper Heat Wall Mount Systems collection.

Line Set Cover Parts

A mini split line set cover is a rigid channel that runs along the outside wall. It hides the copper lines, wiring, and drain hose that run between the indoor and outdoor units.

This collection includes every piece needed to build a full cover run:

• Straight couplings and sockets to join sections

• 45 and 90 degree elbows, both horizontal and vertical

• Universal elbows that bend and twist to fit odd angles

• Wall entry fittings where the lines pass through the wall

• Corner caps and soffit entry fittings for rooflines

• T-joints, flexible joints, reducers, and end sockets

Picture a two-story home with copper lines running up the siding. A matched lineset cover hides all of it behind one clean, paintable channel that blends into the wall.

Understanding the 75, 100, and 140 Sizes

Most cover fittings come in three sizes: 75, 100, and 140. The number is the width of the cover in millimeters, which works out to about 3, 4, and 5-1/2 inches.

A simple way to choose:

• 75 for smaller single-zone systems with thin line sets

• 100 for mid-size systems or a few bundled lines

• 140 for larger systems or several line sets in one run

Wall Covers and Finishing Pieces

Where the lines go into the house, a mini split wall cover gives the opening a neat, finished look. Wall covers and long wall inlets seal off the entry point and keep the outside of the home tidy.

Electrical Connectors and Relays

Some mini split accessories add features to your system rather than covering it.

What's available:

• CN51 and CN32 connectors for remote on/off and extra control options

• Humidifier and ERV control relays to link other equipment

• A separate terminal power block for power wiring options

These parts are handy on ducted systems, like those in the Mitsubishi Single Zone Hyper Heat Slim Ducted Systems collection, where a humidifier or ERV often runs alongside the heat pump.

Outdoor and Drain Accessories

A few more mini split parts round out the collection:

• An outdoor unit mounting base that lifts the unit off the ground

• A drain socket for condensate from the outdoor unit

• An air outlet shutter plate for indoor units

Frequently Asked Questions
