How To Install A Mini Split Heat Pump System

In this video, plumbing and heating practiced Richard Trethewey explains the purpose of a mini split ductless air conditioner and the process of getting 1 installed.

How Does a Mini Split Piece of work?

It'southward elementary physics—rut volition always transfer to cold. Using something called an inverter, the mini divide is capable of capturing rut through a common cold line of refrigerant and moving it to the desired location.

In the summer, the heat is extracted from the air in the business firm and dumped outside, making it common cold. In the winter, heat is scavenged from the outside and pushed back into the business firm. This creates heating and cooling year-round.

Because at that place are no ducts to retrofit, the system is unproblematic for a pro to install. And it provides first-class dehumidification, quiet functioning, and great efficiency. Need to conform the temperature or turn the unit off? Just use the remote control.

How Much Space Can a Mini Carve up Cool?

A unmarried air handler can heat or cool up to 1,000 square feet, depending on the climate and system size. (In heating way, information technology functions downwards to minus 13 degrees F, not a problem where you lot live.)

For larger spaces, up to four independently controlled indoor units can connect to one condenser, for the ultimate in zoned condolement.

Steps for Installing a Mini Split

Every mini split installation needs the following criteria met:

• A location to mount the unit of measurement
• Access to electrical connections
• Access for a condenser outside

Footstep 1: Install the Condenser

This unit should go in a shaded location outside the firm where it can have at to the lowest degree four inches of clearance backside information technology and 20 inches of clearance higher up it and in front of it. The 119-pound unit of measurement tin can exist mounted on brackets fastened to the wall, as shown, or bolted to concrete blocks resting on the ground.

Stride 2: Locate the Air Handler

It mounts on an outside wall no more than 33 feet from the outdoor unit, at least ii⅛ inches below the ceiling and three feet from a Tv set. Starting time, the mounting plate is screwed to the studs, as shown. At the plate's lower-right corner, the installer drills through the wall with a iii-inch pigsty saw. Exterior, a connecting hole is drilled ¼ inch beneath the 1 inside.

Footstep three: Mount the Air Handler

With the cover off, the command wire, refrigerant lines, and condensate drain hose are attached to the unit and taped together, and a protective sleeve is fitted into the hole in the wall. The unit is hoisted upwards without its fins being touched, and the taped parts are fed through the sleeve, every bit shown. The unit then mounts to the plate.

Pace 4: Set Up the Condenser

The outdoor unit of measurement is connected to the command wire from the indoor unit of measurement and to a jacketed ability cable leading to the billow panel. Then the ends of the refrigerant lines are fastened to the condenser with flare nuts, as shown. Flare basics are as well used to join these lines to the ones on the indoor unit of measurement.

Step 5: Hibernate the lines

A plastic channel screwed to the siding hides the lines, condensate hose, and control wire. After the hose is checked to make sure it drains freely, the cease of the hole sleeve is sealed with silicone to prevent water infiltration. Then the channel is capped, as shown.

Step 6: Pump and Embrace

A gauge manifold and a vacuum pump are hooked up to the refrigerant lines to detect leaks and dry the lines as refrigerant is pumped into them. The final step is to put the cover on the air handler, equally shown. The system is and so ready to heat and cool.

Installing a mini split up is an involved process, so Richard recruited the help of Boston Standard Plumbing for the installation.
