INTRODUCTION TO REFRIGERANTS R32 (Only for R32 Model)

The refrigerants used for air conditioners are environmentally friendly hydrocarbons R32. This kind of refrigerant is combustible and odorless. Moreover, it can burn and explode under certain conditions. However, there will be no risk of burning and explosion if you comply with the following table to install your air conditioner in a room with an appropriate area and use it correctly. Compared with ordinary refrigerants, Refrigerant R32 is environmentally friendly and does not destroy the ozone sphere and its value of greenhouse effect is also very low.

Room area requests for air conditioner with Refrigerant R32:

ELECTRICAL REQUIREMENTS

⚠️ WARNING

The electrical ratings for your air conditioner are listed on the model and serial number label located on the front left side of the unit (when facing the front). Specific electrical requirements are listed in the chart below. Follow the requirements below for the type of plug on the power supply cord.

Electrical Shock Hazard:

• Plug into a grounded 3 prong outlet.
• Do not remove the ground prong.
• Do not use an adapter.
• Do not use an extension cord.

Failure to follow these instructions can result in death, fire, or electrical shock.

Recommended Ground Method:

For your personal safety, this air conditioner must be grounded. This air conditioner is equipped with a 3 prong power supply cord with a grounded plug. To minimize the possibility of electrical shock, the cord must be plugged into a 3 prong outlet and grounded in accordance with all local codes and ordinances. If a 3 prong outlet is not available, it is the customer's responsibility to have a properly grounded 3 prong outlet installed by a qualified electrician.

Customer Responsibility:

• To contact a qualified electrician.
• To assure that the electrical installation is adequate and in conformance with the National Electrical Code, ANSI/NFPA 70 - latest edition, and all local codes and ordinances.

Copies of the standards listed may be obtained from: National Fire Protection Association, One Batterymarch Park, Quincy, Massachusetts 02269.

Wiring Requirements and Power Supply Cord:

LCDI Power Cord and Plug:

This air conditioner is equipped with an LCDI (Leakage Current Detection and Interruption) power cord that is required by UL. This power supply cord contains state-of-the-art electronics that sense leakage current. If the cord is damaged and leakage occurs, power will be disconnected from the unit.

The test and reset buttons on the LCDI Plug are used to check if the plug is functioning properly. To test the plug:

1. Plug power cord into a grounded 3 prong outlet.
2. Press RESET ? (on some units a green light will turn on).
3. Press the TEST Button, the circuit should trip and cut all power to the air conditioner (on some units a green light may turn off).
4. Press the RESET button for use. You will hear a click and the A/C is not ready for use.

NOTES:

• The RESET button must be engaged for proper use.
• The power supply cord must be replaced if it fails to trip when the TEST button is pressed and the unit fails to reset.
• Do not use the power supply cord as an ON/OFF switch. The power supply cord is designed as a protection device.
• A damaged power supply cord must be replaced with a new power supply cord.
• The power supply cord contains new user serviceable parts. Opening the tamper-resistant case voids all warranty and performance claims.

NOTE: Your unit's power cord and plug may differ from the one shown. [Image of LCDI plug]

8. Cut foam seal and insert in the space between the upper and lower sashes as shown.

[Diagram showing window seal sponge placement.]

Storm Window Requirements

A storm window frame will not allow the air conditioner to tilt properly which in turn will keep it from draining properly. To adjust for this, attach a board or piece of wood to the sill. The board or wood piece should have a depth of at least 1/2". Make sure the board or piece of wood is approximately 1/2" higher than the storm window frame. This will allow the air conditioner to tilt enough for proper drainage.

[Diagram showing storm window obstruction and required wood piece for drainage. Labels: SASH, Storm Window Frame or Obstruction, 1/2" MIN, 16" MIN. Text: Board or wood piece must be approximately 1/2" higher than the storm window frame for proper drainage.]

THROUGH-THE-WALL INSTALLATION INSTRUCTIONS - OPTIONAL

The case may be installed through-the-wall as optional. Read completely, then follow step-by-step.

NOTE: Obtain all materials locally for mounting the air conditioner through-the-wall.

IMPORTANT

Building a wooden frame is required when installing the case through-the-wall. The opening and dimension of wooden frame is required as below.

NOTE: The allowed maximum wall thickness is less than 8 9/10". Otherwise, the wall will block the air inlet of the outdoor side, it will affect the normally operation of unit.

1. Build a wooden frame into the wall opening and make sure fasten securely, which is suitable to the WALL OPENING REQUIREMENT.

[Diagram showing wooden frame dimensions and wall thickness. Labels: Frame Thickness, Inside Frame Height, Inside Frame Width, The Maximum Wall thickness 8 9/10"(225mm).]

2. Remove the air conditioner from the carton box and take off the chassis as window mounting installation.
3. Place the cabinet into the wooden frame, and lock the cabinet by the top rail hole and bottom chassis hole with 1" long wood screws as shown, from inside to outside.
4. Assemble the two Support Bracket with Sill Angle Bracket to the cabinet against to the wooden frame as window mounting installation instructions.

[Diagram showing cabinet placement and locking with screws. Labels: Support bracket, Bolt and Locknut, Sill angle bracket.]

5. Assemble the chassis into the cabinet and fasten or lock it, as window mounting installation instructions.

Through-the-wall installation is not appropriate, if any of the side or top louvers of case is obstructed by the wall. All side and top louvers in the case must project on the outdoor side of the wall. The room side of the case must project into the room far enough to maximize the balance of the unit. The case must be installed level from side to side and with a slight tilt from front to rear. Use a level, no more than a 1/2 bubble will be correct slant to the outside. Lintel angle is required to support bricks or blocks above opening. Flashing is required and should extend the length of the opening to ensure no inside cavity leakage occurs.
