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 should 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 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 diagrams 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.
STEP 2: MOUNT INDOOR UNIT
Depending on the model, fix the mounting plate or brackets to the wall with
tapping screws and mount the unit. The bottom of the unit can touch the floor
or remain suspended, but the body must be installed vertically. Refer to the
diagrams below.
WARNING
Ensure that the indoor unit is completely level. Improper installation can
cause the drain pipe to back up into the unit and water leaks.
STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPING
- Determine the location of the wall hole based on the location of the outdoor unit.
- Using 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.
- Place the protective wall hole sleeve (field supplied) 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 sleeve cover to the wall sleeve on the outside end. Make sure the cover is flush with the outside wall.
STEP 4: REMOVE FRONT PANEL AND FACE PLATE
To facilitate pipe and cable installation remove the front panel and face
plate on the unit.
- Slide the two tabs at the top of the front panel inward until they click.
- Remove the four screws holding the face plate in place. Open at the bottom 30o and lift off the face plate.
- Using a screwdriver, remove the string attached to the front panel. Gently let the front panel fall forward and remove it.
STEP 5: CONNECT DRAIN PIPE
The drain pipe is used to drain condensate water away from the unit. Improper
installation may cause leaks and unit or property damage.
-
Connect the drain pipe (field supplied) to the unit’s connecting port using a metal worm clamp.
Make sure it secured tightly and can not be easily pulled loose. -
Insulate the connecting port and pipe with the accessory sheath (sleeve) provided.
-
Install the drain pipe with a downward slope of at least a 1/100 gradient to prevent water from flowing back into the unit. If connecting multiple units, install the pipes as illustrated.
STEP 6: CONNECT SIGNAL CABLE
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS
- All wiring must comply with local and national electrical codes and regulations, and must be installed by a licensed electrician.
- All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units.
- 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.
- Power voltage should be within 90-110% of rated voltage. Insufficient power supply can cause malfunction, electrical shock, or fire.
- 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.
- 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.
- Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet.
- Make sure to properly ground the air conditioner.
- Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in product malfunction and possible fire.
- Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit.
- If the unit has an auxiliary electric heater, it must be installed at least 40″ away from any combustible materials.
- 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
- Indoor Power Cable (if applicable): H05VV-F or H05V2V2-F
- 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 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 (see diagram on next page)
- Prepare the cable for connection:
- Using wire strippers, strip the jacket from both ends of the cable to reveal about 6″ of the wires.
- Strip the insulation from the ends of the wires.
- Using a wire crimper, crimp u-lugs to the ends of the wires.
- Rotate the sensor bracket upward then remove the electrical box cover.
- Unscrew the cable clamp below the terminal block and place it to the side.
- Refer to the wiring diagram on the control box cover and connect the u-lugs to the terminal block. Firmly screw the u-lug of each wire to its corresponding terminal.
- 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.
- Replace the control box lid.
WARNING
All wiring must be performed strictly in accordance with the wiring diagram
located on the inside of the control box lid.
STEP 7: PREPARE REFRIGERANT PIPING
- If pre-existing refrigerant piping is already embedded in the wall, begin the outdoor unit installation. Refer to the Refrigerant Piping Connections section of the outdoor unit’s installation manual for detailed instructions.
- 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: WRAP PIPES AND CABLE
Before passing the refrigerant piping, drain pipe, and the signal cable
through the wall hole, you must bundle them together to save space, protect
them, and insulate them.
-
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.
- DO NOT intertwine the signal cable with any of the other wires while bundling these items together.
-
Using adhesive vinyl tape, attach the drain pipe to the underside of the refrigerant pipes.
-
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
Electrical and Gas Leak Checks section of the outdoor unit’s installation
manual).
