5. Indoor Unit Installation

PRIOR TO INSTALLATION

Before installing, check the product box label to ensure the indoor unit model number matches the outdoor unit model number.

Step 1: Select Installation Location

Choose an appropriate location based on the following standards:

• Good air circulation
• Convenient drainage
• Noise from the unit will not disturb others
• Firm and solid location (will not vibrate)
• Strong enough to support the unit's weight
• At least three feet from other electrical devices (e.g., TV, radio, computer)

(Diagram Fig 3.1 illustrates required clearances: 6 inches or more from ceiling, 4.75 inches or more from side walls, and 6 feet or more from the floor.)

DO NOT install unit in the following locations:

• Near any source of heat, steam, or combustible gas
• Near flammable items (e.g., curtains, clothing)
• Near any obstacle that might block air circulation
• Near the doorway
• In a location subject to direct sunlight

NOTE ABOUT WALL HOLE:

If no fixed refrigerant piping is present, ensure ample room for a wall hole for the signal cable and refrigerant piping. The default piping exit is the right side of the indoor unit, but it can accommodate piping to the left or right.

Step 2: Attach Mounting Plate to Wall

The mounting plate is where the indoor unit is mounted.

1. Remove the screw attaching the mounting plate to the back of the indoor unit.
2. Place the mounting plate against the wall in the selected location.
3. Drill holes for mounting screws, ensuring they align with wall studs for support and match the plate's screw holes.
4. Secure the mounting plate to the wall with the provided screws.
5. Ensure the mounting plate is flat against the wall.

NOTE FOR CONCRETE OR BRICK WALLS: For brick or concrete walls, drill 5mm-diameter holes and insert sleeve anchors. Secure the mounting plate by tightening screws into the clip anchors.

Step 3: Drill Wall Hole for Connective Piping

Drill a hole in the wall for the refrigerant piping, drainage pipe, and signal cable.

1. Determine the wall hole location based on the mounting plate position. Refer to 'Mounting Plate Dimensions' for optimal placement. The hole should be at least 2.5 inches in diameter and angled slightly downward towards the outside to facilitate drainage.
2. Using a 2.5in or 3.5in core drill (depending on model), drill the hole. Ensure the outdoor end of the hole is 1/4" to 1/2" lower than the indoor end for proper water drainage. (See Fig. 3.2)
3. Insert a protective wall cuff into the hole to protect edges and help seal the installation.

(Fig. 3.2 illustrates the wall penetration from indoor to outdoor, showing the downward angle.)

MOUNTING PLATE DIMENSIONS: Different models have different mounting plates. Diagrams show plate types and dimensions including width, height, unit-to-plate width/height, recommended wall hole position, and screw hole distances for models BM09M22WM, BM12M22WM, BM18M21WM, and BM24M21WM.

(Diagrams show specific dimensions for each model and correct/incorrect mounting plate orientations.)

NOTE: When the gas side connective pipe is 5/8" or more, the wall hole diameter should be 3.5 inches.

❗ CAUTION: When drilling, avoid wires, plumbing, and other sensitive components.

Step 4: Prepare Refrigerant Piping

The refrigerant piping has an insulating sleeve. Prepare it before passing through the wall hole. Refer to the 'Refrigerant Piping Connection' section for details on flaring and torque.

1. Choose the side for piping exit based on the wall hole position relative to the mounting plate.
2. If the wall hole is behind the unit, keep the knock-out panel in place. If to the side, remove the plastic knock-out panel to create an exit slot. Needle nose pliers may be needed if the panel is difficult to remove. (See Fig. 3.3)
3. Cut the insulating sleeve to reveal about 6 inches of refrigerant piping. This aids connection and leak checks.
4. If existing piping is in the wall, proceed to 'Connect Drain Hose'. If not, connect the indoor unit's piping to the connective piping. Refer to 'Refrigerant Piping Connection' section.
5. Determine the necessary angle for your piping based on the wall hole and mounting plate position.
6. Grip the piping at the base of the bend.
7. Slowly bend the piping towards the hole with even pressure. Do not dent or damage the piping.

(Fig. 3.3 shows the knock-out panel. Fig. 3.4 illustrates piping angle options: Left-hand side, Left rear, Right-hand side (not recommended due to tight bend), and Right rear.)

NOTE ON PIPING ANGLE: Right-hand side piping angle is not recommended due to the very tight bend.

❗ CAUTION: Be extremely careful not to dent or damage the piping. Dents affect unit performance.

Step 5: Connect Drain Hose

The drain hose is typically attached to the left-hand side of the unit (facing the back), but can be moved to the right-hand side.

1. Attach the drain hose on the same side as the refrigerant piping exit for proper drainage.
2. Attach a drain hose extension (purchased separately) to the end of the drain hose.
3. Wrap the connection point with Teflon tape for a good seal and to prevent leaks.
4. Wrap the portion of the drain hose that remains indoors with foam pipe insulation to prevent condensation.
5. Remove the air filter and pour a small amount of water into the drain pan to ensure smooth water flow.

PLUG THE UNUSED DRAIN HOLE: Use the provided rubber plug to prevent unwanted leaks.

NOTE ON DRAIN HOSE PLACEMENT:

• Arrange the drain hose according to Fig. 3.5.
• DO NOT kink the drain hose.
• DO NOT run the drain hose across the back of the unit; move it to the opposite side if needed.
• DO NOT place the end of the drain hose in water or a container that will collect water.

(Diagrams Fig 3.5-3.8 show correct and incorrect drain hose routing, emphasizing no kinks and proper drainage into a collection pan, not submerged.)

Step 6: Wiring Connections

The signal cable enables communication and power between indoor and outdoor units. Use 14 gauge, 4 conductor stranded copper wire.

BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS:

• All wiring must comply with local and national electrical codes and be installed by a licensed electrician.
• Electrical connections must follow the Electrical Connection Diagram on the unit panels.
• If there is a serious safety issue with the power supply, stop work immediately.
• Power voltage should be within 90-110% of rated voltage. Insufficient power can cause malfunction, shock, or fire.
• The outdoor unit must be powered by a dedicated circuit with the correctly sized circuit breaker.
• An approved electrical disconnect switch must be installed between the outdoor unit and the circuit breaker.
• Properly ground the air conditioner.
• Every wire must be firmly connected. Loose wiring can cause overheating, malfunction, or fire.
• Do not let wires touch or rest against refrigerant tubing, the compressor, or moving parts.

WARNING: BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF THE MAIN POWER TO THE SYSTEM.

Wiring Procedure:

1. Prepare the cable: Strip rubber jacket and insulation from signal cable ends. Crimp u-type lugs onto wire ends.
2. Open the front panel of the indoor unit.
3. Open the wire box cover on the right side to reveal the terminal block.
4. Unscrew and set aside the cable clamp below the terminal block.
5. Remove the plastic panel on the bottom left-hand side of the back of the unit.
6. Feed the signal wire through the slot from the back to the front.
7. Match wire colors (Black, White, Red, Green) to terminal block labels (B, W, R, G). Connect the u-lug and firmly screw each wire to its terminal.
8. (Diagram shows terminal block with labels 1, 2, 3 and wire colors B, W, R, G.)
9. ❗ CAUTION: DO NOT MIX UP LIVE AND NULL WIRES. This is dangerous and can cause malfunction.
10. After checking connections, use the cable clamp to fasten the signal cable to the unit.
11. Replace the wire cover and the plastic panel.

WARNING: All wiring must be performed strictly in accordance with local and national wiring codes.

Step 7: Wrap Piping and Cables

Bundle the drain hose, refrigerant pipes, and signal cable together to save space, protect them, and insulate them before passing through the wall hole.

1. Bundle items as shown in Fig. 3.10.
2. Use adhesive vinyl tape to attach the drain hose to the underside of the refrigerant pipes.
3. Use insulation tape to wrap the signal wire, refrigerant pipes, and drain hose tightly together. Ensure all items are bundled according to Fig. 3.10.

(Fig. 3.10 shows the bundled components: space behind unit, refrigerant piping, insulation tape, signal wire, and drain hose. It notes that the drain hose must be on the bottom to prevent overflow and fire/water damage.)

DO NOT WRAP ENDS OF PIPING: Keep piping ends unwrapped for leak testing.

DO NOT INTERTWINE SIGNAL CABLE WITH OTHER WIRES: Avoid crossing the signal cable with any other wiring.

Step 8: Mount Indoor Unit

If new connective piping was installed to the outdoor unit:

1. If refrigerant piping is already embedded in the wall:
1. Hook the top of the indoor unit onto the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, providing room to connect piping, signal cable, and drain hose. (See Fig. 3.11)
3. Connect drain hose and refrigerant piping (refer to 'Refrigerant Piping Connection' section).
4. Keep the pipe connection point exposed for leak testing (refer to 'Electrical Checks and Leak Checks' section).
5. After leak testing, wrap the connection point with insulation tape.
6. Remove the bracket or wedge.
7. Push down on the bottom half of the unit until it snaps onto the hooks along the bottom of the mounting plate.
2. If refrigerant piping was NOT already embedded in the wall:
1. Pass the wrapped bundle of pipes, drain hose, and signal wire through the wall hole.
2. Hook the top of the indoor unit on the upper hook of the mounting plate.
3. Check that the unit is firmly hooked by applying slight pressure to the sides; it should not jiggle or shift.
4. Push down on the bottom half of the unit with even pressure until it snaps onto the bottom hooks of the mounting plate.
5. Re-check that the unit is firmly mounted.

UNIT IS ADJUSTABLE: The unit can be adjusted left or right by approximately 1.25"- 2.0" if there isn't enough room to connect embedded pipes. (See Fig. 3.12)

(Fig. 3.11 shows a wedge propping the unit. Fig. 3.12 illustrates the left/right adjustability.)

6. Refrigerant Piping Connection

Proper preparation and connection of refrigerant piping are crucial for efficient operation and longevity.

Note on Pipe Length

Pipe length affects performance and energy efficiency. Nominal efficiency is tested at 16.5ft. In North America, standard pipe length is 25'. A minimum pipe run of 10 feet is required to minimize vibration and noise. Refer to the table below for specifications.

Connection Instructions – Refrigerant Piping

Step 1: Cut pipes

Cut and flare pipes properly for efficient operation and minimal maintenance.

1. Measure the distance between the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe slightly longer than the measured distance.
3. Ensure the pipe is cut at a perfect 90° angle. (See Fig. 5.1 for bad cut examples: Oblique, Rough, Warped.)
4. (Fig. 5.1 shows examples of incorrect pipe cuts.)
5. DO NOT DEFORM PIPE WHILE CUTTING: Be careful not to damage, dent, or deform the pipe, as this reduces heating efficiency.

Step 2: Remove burrs

Burrs must be completely removed to ensure an air-tight seal.

1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

(Fig. 5.2 shows a reamer being used to remove burrs from a pipe end.)

Step 3: Flare pipe ends

Proper flaring is essential for an airtight seal.

1. After removing burrs, seal pipe ends with PVC tape to prevent foreign material entry.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of the pipe, ensuring they face the correct direction, as they cannot be changed after flaring. (See Fig. 5.3)
4. (Fig. 5.3 shows a flare nut and copper pipe.)
5. Remove PVC tape from pipe ends before flaring.
6. Clamp the flare form onto the pipe end. The pipe end must extend beyond the flare form edge according to the table dimensions. (See Fig. 5.4)
7. (Fig. 5.4 shows a flare form being clamped onto a pipe. Table 7.1 provides Torque Chart and Flaring Guide for different pipe gauges, torque, and flare dimensions.)
8. Place the flaring tool onto the form.
9. Turn the flaring tool handle clockwise until the pipe is fully flared.
10. Remove the flaring tool and form, then inspect the pipe end for cracks and even flaring.

(Fig. 5.5 illustrates the flare shape and dimensions.)

Step 4: Connect pipes

Connect refrigerant pipes carefully, avoiding excessive torque or deformation. Connect the low-pressure pipe first, then the high-pressure pipe.

MINIMUM BEND RADIUS: The minimum bending radius for connective refrigerant piping is 4 inches. (See Fig. 5.6)

(Fig. 5.6 shows a pipe with a bend radius indicator.)

Note: Use of an approved refrigerant sealant is recommended for all flare joint connections.

Instructions for Connecting Piping to Indoor Unit:

1. Align the center of the two pipes to be connected. (See Fig. 5.7)
2. (Fig. 5.7 shows indoor unit tubing, a flare nut, and a pipe being aligned.)
3. Tighten the flare nut as tightly as possible by hand.
4. Using a spanner, grip the nut on the unit tubing.
5. While gripping the unit tubing nut, use a torque wrench to tighten the flare nut according to the Torque Requirements table. Loosen slightly, then re-tighten.
6. (Fig. 5.8 shows tightening a flare nut with a torque wrench.)

DO NOT USE EXCESSIVE TORQUE: Excessive force can break the nut or damage the refrigerant piping.
