Introduction to Refrigerants R32

The refrigerants used for air conditioners are environmentally friendly hydrocarbons R32. This 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 guidelines 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 layer, and its value of greenhouse effect is also very low.

Room Area Requirements for Air Conditioner with Refrigerant R32

Electrical Requirements

Wiring Requirements

• 115 volt (103 min. - 127 max)
• 0-8 amps
• 10-amp time-delay fuse or circuit breaker
• Use on single outlet circuit only

Power Supply Cord: [Image description: A three-prong power plug.]

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.

It is the customer's 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.

LCDI Power Cord and Plug

This air conditioner is equipped with an LCDI (Leakage Current Detection and Interruption) power cord and plug as required by US National Electric Code 440.65. This cord consists of a length of shielded flexible cord with no termination on the load side and a LCDI attachment plug on the line side.

The LCDI power cord and plug will remove the supply source via electrical disconnect (circuit trip) if the nominal current leakage between the cord shield and either load conductor exceeds a predetermined value. The cord will remain de-energized until the device has been manually reset. This is intended to reduce the risk of a fire in the power cord or combustible materials nearby. The cord shields are not grounded and they must be considered a shock hazard if exposed. The cord shield must not be connected to ground or to any exposed metal.

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 wall outlet.
2. Press the [Test Button]. The circuit should trip and cut all power to the air conditioner.
3. Press the [Reset Button] for use.

If a test is performed and the indicator light remains ON, current leakage has been detected. Do not use the air conditioner or attempt to reset the LCDI Plug. Contact Customer Service for troubleshooting recommendations.

FIG. 4: Illustration showing adjustment of accordion panel rails.

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 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. (See FIG. 5).

FIG. 5: Diagram showing a storm window frame, sash, and a board attached to the sill, indicating the required height difference for drainage.

Placing the Unit Inside a Window

1. Place the air conditioner on the sill with the bottom mounting rail against its back edge. Center the air conditioner and close the window securely behind the top mounting rail. The air conditioner should be slightly tilted to the outside area. Use a level; about a 1/3 bubble will be the correct case slant to the outside. (See FIG. 6 & FIG. 7) (It is suggested to keep a downward angle to let accumulated rain water drain out from the back side of the unit bottom.)
