INSTALLATION OVERVIEW – INDOOR UNIT

INDOOR UNIT INSTALLATION
STEP 1: SELECT INSTALLATION LOCATION
Before installing the indoor unit, you must choose an appropriate location. The following standards must be met for an appropriate location for the unit:

• Good air circulation
• Convenient drainage
• Noise from the unit will not disturb other people
• Firm and solid – the location will not vibrate
• Strong enough to support the weight of the unit
• A location at least three feet (one meter) from all other electrical devices (e.g., TV, radio, computer)

DO NOT install the unit in the following locations:

• Near any source of heat, steam, or combustible gas
• Near flammable items such as curtains or clothing
• Near any obstacle that might block air circulation
• Near a doorway
• In a location subject to direct sunlight

Refer to the following diagram to ensure proper distance from walls and ceiling:

NOTE
If there is no pre-existing refrigerant piping, when choosing a location, leave ample room for a wall hole (see Step 3: Drill Wall Hole for Connective Piping) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to either the left or right.

STEP 2: ATTACH THE MOUNTING PLATE TO THE WALL

1. Remove the screw that attaches the mounting plate to the back of the indoor unit. The mounting plate is the bracket on which you will mount the indoor unit.
2. Secure the mounting plate to the wall with the anchors and screws provided. Make sure that the mounting plate is flat against the wall, and is level.

STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPING

1. Determine the location of the wall hole based on your unit’s mounting plate dimensions. Use the installation template provided with the indoor unit to correctly position the wall hole, or refer to the illustration below.
2. Use a 2 1/2″ (65mm) core drill for units with a gas side connective pipe less than 5/8″ (16mm), or 3 1/2″ (90mm) for units with a gas side pipe greater than or equal to 5/8″ (16mm), drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle so that the outdoor end of the hole is lower than the indoor end by about 3/16 – 1/4″ (5mm to 7mm). This will ensure proper water drainage. installation template provided with the indoor unit to correctly position the wall hole, or refer to the illustration below.
3. Place the protective wall hole sleeve into the hole. This protects pipes and cables from sharp edges and will help seal the opening when you finish the installation process. After the sleeve is inserted through the wall, connect the wall hole cover to the wall sleeve on the outside end. Make sure the cover is flush with the outside wall.

STEP 4: PREPARE REFRIGERANT PIPING

1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit (left or right).
2. If the wall hole is behind the unit, do not remove the knock-out panel. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. This will create a slot through which your piping can exit the unit. Use needle nose pliers or cutters if the plastic panel is too difficult to remove by hand. Grooves have been made in the knock-out panel to cut it to size conveniently. The size of the piece removed is determined by the diameter of the piping.
3. If pre-existing connective piping is already embedded in the wall, proceed directly to Step 5: Connect the Drain Pipe. If there is no pre-existing piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connections section of your outdoor unit’s installation manual for detailed instructions.
4. Position the piping to align with the wall hole. The refrigerant piping can exit the indoor unit from four different angles: left-hand side, right-hand side, left rear, or right rear.

WARNING
Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit’s performance.

STEP 5: CONNECT THE DRAIN PIPE
By default, the unit’s drain pipe is attached to the left-hand side of the unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain pipe on the same side that your refrigerant piping exits the unit. Attach any drain pipe extension (purchased separately) to the end of the drain pipe. Any drain pipe extension must have an inner diameter of 5/8″ (16mm) and tightly fit the unit’s existing drain pipe.

• Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
• For the portion of the drain pipe that will remain indoors, wrap it with foam pipe insulation to prevent condensation.
• Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.
• Make sure to arrange the drain pipe according to the following illustration.

WARNING
PLUG THE UNUSED DRAIN HOLE. To prevent unwanted leaks you must plug the unused drain hole with the rubber plug provided.

STEP 6: CONNECT SIGNAL CABLE
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS

1. All wiring must comply with local and national electrical codes and regulations and must be installed by a licensed electrician.
2. All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units.
3. If there is a serious safety issue with the power supply, stop work immediately and contact a licensed electrician. Do not continue with the installation until the safety issue is properly resolved.
4. Power voltage should be within 90-110% of the rated voltage. Insufficient power supply can cause malfunction, electrical shock, or fire.
5. If connecting power to fixed wiring, install a surge protector and main power switch with a capacity of 1.5 times the maximum current of the unit.
6. If connecting power to fixed wiring, a switch or circuit breaker that disconnects all poles and has a contact separation of at least 1/8″ (3mm) must be incorporated in the fixed wiring. A qualified technician must use an approved circuit breaker or switch.
7. Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in product malfunction and possible fire.
10. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit.
11. If the unit has an auxiliary electric heater, it must be installed at least 40″ away from any combustible materials.
12. To avoid getting an electric shock, never touch the electrical components soon after the power supply has been turned off. After turning off the power, always wait 10 minutes or more before you touch the electrical components.

WARNING
Before performing any electrical or wiring work, turn off the main power to the system.

The signal cable enables communication between the indoor and outdoor units. You must first choose the right cable size before preparing it for connection.

USE THE RIGHT CABLE

• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F

CABLE SIZING
Use a minimum of 16 AWG for power and signal cables connected to and between the indoor and outdoor units.
Choose the correct size of cable
The size of the outdoor power supply cable, signal cable, fuse, and switch needed is determined by the maximum current of the unit. The maximum current is indicated on the nameplate located on the side panel of the unit. Refer to this nameplate to choose the right cable, fuse, or switch.

Wiring the Indoor Unit

1. Open the front panel of the indoor unit.
2. Using a screwdriver, open the wire box cover on the right side of the unit. This will reveal the terminal block.
3. Unscrew the cable clamp below the terminal block and place it to the side.
4. Facing the back of the unit, remove the plastic panel on the bottom left-hand side.
5. Feed the signal wire through this slot, from the back of the unit to the front.
6. Facing the front of the unit, connect the wire according to the indoor unit’s wiring diagram, connect the u-lug, and firmly screw each wire to its corresponding terminal.
7. After checking to make sure every connection is secure, use the cable clamp to fasten the signal cable to the unit. Screw the cable clamp down tightly.
8. Replace the wire cover on the front of the unit and the plastic panel on the back.

WARNING
All wiring must be performed strictly under the wiring diagram located on the back of the indoor unit’s front panel.

STEP 7: PREPARE REFRIGERANT PIPING

1. If pre-existing refrigerant piping is already embedded in the wall, skip to Step 9. Then, begin the outdoor unit installation. Refer to the Refrigerant Piping Connections section of the outdoor unit’s installation manual for detailed instructions.
2. If there is no pre-existing piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connections section of the outdoor unit’s installation manual for detailed instructions.

STEP 8: WRAPPING THE CABLES
Before passing the piping, drain pipe, and signal cable through the wall hole, you must bundle them together to save space, protect them, and insulate them.

1. Bundle the drain pipe, refrigerant pipes, and signal cable as shown below:
   NOTE
   The drain pipe MUST be at the bottom of the bundle. Putting the drain pipe at the top of the bundle can cause the drain pan to overflow, which can lead to fire or water damage.
   NOTE
   DO NOT intertwine the signal cable with any of the other wires while bundling these items together.

2. Using adhesive vinyl tape, attach the drain pipe to the underside of the refrigerant pipes.

3. Using insulation tape, wrap the signal wire, refrigerant pipes, and drain pipe tightly together.
   Double-check that all items are bundled.

NOTE
When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for leaks at the end of the installation process (refer to the Electrical and Gas Leak Checks section of this manual).

STEP 9: MOUNT INDOOR UNIT
If you installed new connective piping to the outdoor unit, do the following:

1. If you have already passed the refrigerant piping through the hole in the wall, proceed to #4.
2. Double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain pipe, and signal wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that the unit is hooked firmly on the mounting by applying slight pressure to the left- and right-hand sides of the unit. The unit should not jiggle or shift.
6. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and right sides of the unit.

If refrigerant piping is already embedded in the wall, do the following:

1. Hook the top of the indoor unit on the upper hook of the mounting plate.

2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the refrigerant piping, signal cable, and drain pipe.
   NOTE
   We recommend a second person is present to assist with supporting the indoor unit while the first person makes all applicable connections.

3. Connect drain pipe and refrigerant piping (refer to the Refrigerant Piping Connections section of the outdoor unit installation manual for instructions).

4. Keep pipe connection point exposed to perform the leak test (refer to the Electrical and Gas Leak Checks section of the outdoor unit’s installation manual).

5. After the leak test, wrap the connection point with insulation tape.

6. Remove the bracket or wedge that is propping up the unit, if applicable.

7. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.

NOTE
The indoor unit is adjustable. The hooks on the mounting plate are smaller than the holes on the back of the unit. If you find that you don’t have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about 1 1/4-2″ (30-50mm), depending on the model.
