Before Operation

Preparing for Operation

1. Plug in the power cord properly.
2. Use a dedicated circuit. Overloading the line could create a fire hazard.
3. Do not use an extension cord. See page 11 for more details.
4. Do not start/stop operation by plugging/unplugging the power cord.
5. If the power cord is damaged and requires replacement, have an Authorized Servicer install an exact replacement part.

Usage

1. Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.
4. The air conditioner is a consumer comfort appliance, not a precision climate control system.

Cleaning and Maintenance

1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

Window Requirements

Size

This room air conditioner is designed for installation in standard double-hung windows with actual opening widths from 22" to 36".

The upper and lower window sash must open sufficiently to allow a clear vertical opening of 13" from the bottom of the upper sash to the window stool.

WARNING: This product is a WINDOW AIR CONDITIONER.

As such, a standard single-hung or double-hung window is required for proper installation. Non-window installations, including using sleeves, holes in walls, and other installations are not recommended.

Clearance

Proper clearance enhances the cooling efficiency of the unit and prevents heat radiation of the condenser.

1. If a storm window presents interference, fasten a 2" wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame.
2. See Figure. B. The top of the wood strip should be approximately W higher than the storm window frame (Storm Window Frame) or wood strip (Outdoors) to help condensation to drain properly to the outside.
3. Install a second wood strip (approximately 6" long by 1V2" wide and same thickness as first strip) in the center of the sill flush against the back off the inner sill. This will raise the L bracket as shown Figure. B.
4. If the distance between Storm Window Frame and Wood Strip Mounted on Top of Inner Sill is more than 1", two of wood strips are not necessary.

Preparation of Chassis

1. Insert the guide panels into the guides of the air conditioner. Fasten the curtains to the unit with screws (Type A).

Tip : Use a long screwdriver and installing the screws will be easier.

2. Cut the adhesive-backed seal strip (Type D) to the window width. Remove the backing from the seal strip and attach the seal strip to the underside of the bottom window.

3. Locating unit in window

Open the window and mark center line on the center of the inner sill.

4. Attach L bracket

4.1. Install the L brackets behind the inner window sill, with short side of bracket as shown. Use the 2 screws (Type A) provided.

4.2. The bracket helps to hold unit securely in place. Be sure to place bracket edge flush against back of inner sill.

Additional Features

Air Direction

Adjusting the air direction using the horizontal air deflector control.

Using the control tabs, the air flow can be directed to the left, right, straight ahead, or any combination of these directions.

Drain Pipe

In humid weather, excess water may cause the Base Pan to overflow. To drain the water, remove the Drain Cap and secure the Drain Pipe to the rear hole of the Base Pan.

Press the drain pipe into the hole by pushing down and away from the fins to avoid injury.

This air conditioner is equipped with a slinger fan. (See drawing, below.)

The fan has an outer ring that runs in the water that collects in the base pan if it gets deep. That condensate is then picked up by the fan and expelled through the condenser, making the air conditioner more efficient.

CAUTION: Be careful when inserting the drain pipe. Push away from the sharp fin area to avoid slipping injuring yourself.

Removal From Window

Turn the air conditioner off, disconnect the power cord, remove the L bracket, the screws and Support Bracket installed through the top and bottom of the guide panels, and save for reinstallation later. Close the guide panels. Keeping a firm grip on the air conditioner, raise the sash, and carefully tilt the air conditioner backward, draining any condensate. Lift the air conditioner from the window and remove the sash seal from between the windows.

Be sure to drain ALL condensate from the air conditioner. If you don't, it could run out while you carry the unit, making a mess and creating a slipping hazard. This simple step will save you much cleaning and make a safer work environment.

Maintenance and Service

Air Filter

Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator. To clean the air filter:

1. Lift the inlet grille.
2. Remove the air filter from the front grille by pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40 °C (104 °F).
4. Gently shake the excess water from the filter and replace.

Cleaning The Air Conditioner

The front grille and Inlet grille may be wiped with a cloth dampened in a mild detergent solution.

The cabinet may be washed with mild soap or detergent and lukewarm water, then polished with Liquid Wax for Appliances.

To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from the atmosphere.

How to Remove the Front Grille

1. Remove the thermostat knob and the operation knob by pulling.
2. Remove the screw securing the Front Grille.

1. Pull the inlet grille forward
2. Remove the screw securing the Front Grille.

3. Push the grille up from the bottom and pull the top of the grille away from the case as the top tabs lift out of their slots.

Common Problems and Solutions

Before Calling for Service

If you have problems with your air conditioner, read the following information and try to solve the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.

Air conditioner does not operate

1. Ensure that the air conditioner is plugged into a proper outlet.
2. Check the fuse or circuit breaker.
3. Check whether the voltage is unusually high or low.

Air does not feel cold enough on the cooling setting

1. Ensure that the temperature settings are correct.
2. Check to see if the air filter is clogged with dust. If so, clean the filter.
3. Ensure that the air flow from the outside is not obstructed and that there is a clearance of over 20" between the back of the air conditioner and the wall or fence behind it.
4. Close all doors and windows and check for any source of heat in the room.

Before calling for service, please review the following list of common problems and solutions.

The air conditioner is operating normally when:

• You hear a pinging noise. This is caused by water being picked up by the fan on rainy days or in highly humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency. See the section on Slinger Fan, page 20.
• You hear the thermostat click. This is caused by the compressor cycle starting and stopping.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit.
• You hear the fan running while the compressor is silent. This is a normal operational feature.
