About the Controls on the Air Conditioner

The controls will look like one of the following.

Controls

Model : CW-C84GU

	Off	- Turns air conditioner off.
	Med Fan	- Med speed fan operation without cooling.
	Low Fan	- Low speed fan operation without cooling.

High Cool - Cooling with high speed fan operation.

Med Cool - Cooling with med speed fan operation.

Low Cool - Cooling with low speed fan operation.

This automatically controls the temperature of the indoor air.

Turn the knob so that arrow points to the higher number for greater cooling. Point the arrow to the lower number for more moderate cooling.

(i.e. the higher the number, the greater the cooling)

• FOR NORMAL COOLING

1.	Turn the operation switch to the High Cool or the Low Cool setting.
2.	Set the Thermostat control to the desired temperature mark 5 (the mid-point is a good starting position).
	If the room temperature is not satisfactory after a reasonable time, adjust the control to a cooler or warmer
	setting, as appropriate.

• FOR MAXIMUM COOLING

1.Turn the Operation Knob to the High Cool setting.

2.Set the Thermostat control to the largest (9) temperature mark.

• FOR QUIETER OPERATION

1.Turn the Operation Knob to the Low Cool setting.

2.Set the Thermostat control as needed.

CAUTION

When the air conditioner has performed its cooling operation and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation again.

How to Secure the 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.(See Fig.1)

Optional(CW3H02502C)

1.Remove the rubber plug and slide the chassis out from the cabinet.(See Fig.2)

2.Install the drain pan over the corner of the cabinet where you removed the plug with 4 (or 2) screws.(See Fig.3)

3.Connect the drain hose to the outlet located at the bottom of the drain pan. You can purchase the drain hose or tubing locally to satisfy your particular needs. (Drain hose is not supplied).(See Fig.3)

4.Select the most appropriate connection from among the figures to the right (by considering the hole of the unit) to fit drain pan to your own unit.(See Fig.3)

5.Slide the chassis back into the cabinet. Reinstall the cabinet screws. Secure the cabinet to chassis by using screws. (See Fig.4)

Care and Maintenance

TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.

Air Filter Cleaning

The air filter behind the front grille should be checked and cleaned at least once every 2 weeks or more often if necessary.

TO REMOVE:

1.Open the inlet grille upward by pulling out the bottom of the inlet grille or downward by pulling out the top of the inlet grille.

2.Using the tab, pull up slightly on the filter to release it and pull it down or up.

3.Clean the filter with warm, soapy water under 40°C (104°F).

4.Rinse and gently shake the water from the filter and let it dry before replacing it.

Conditioner Air the on Controls the About

CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will clog it and reduce performance.

How to Insert Batteries

1.Remove the cover from the back of the remote controller.

2.Insert two AAA dry cell batteries.

•Be sure that the (+) and (-) directions are correct.

•Be sure that both batteries are new.

3.Re-attach the cover.

•Do not use rechargeable batteries. Such batteries differ from standard dry cells in shape, dimensions, and performance.

•Remove the batteries from the remote controller if the air conditioner is not going to be used for an extended length of time.

INSTALLATION

How to Install the Unit

1.To prevent vibration and noise, make sure the unit is installed securely and firmly

2.Install the unit where the sunlight does not shine directly on the unit.

3.The outside of the cabinet must extend outward for at least 28cm (11") and there should be no obstacles, such as a fence or wall, within 50.8cm (20") from the back of the cabinet because it will prevent heat radiation of the condenser.

Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

Heat radiation

About 12.7mm (1/2")

Over 50.8cm (20")

CAUTION: All side louvers of the cabinet must remain exposed to the outside of the structure.

4.Install the unit a little slanted so the back is slightly lower than the front (about 12.7mm (1/2")).

This will force condensed water to flow to the outside.

5.Install the unit with the bottom about 76.2cm (30")~152.4cm (60") above the floor level.

Window Requirements

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.

This unit is designed for installation in standard double hung windows with actual opening widths from 55.88cm (22") to 91.44cm (36").

The top and bottom window sash must open sufficiently to allow a clear vertical opening of 38cm (15") from the bottom of the upper sash to the window stool.

Electrical Safety (Applies to USA and Puerto Rico)

IMPORTANT

(PLEASE READ CAREFULLY)

FOR THE USER'S PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED

The power cord of this appliance is equipped with a three-prong (grounding) plug. Use this with a standard three-slot (grounding) wall power outlet (Fig. 12) to minimize the hazard of electric shock. The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded.

PREFERRED METHOD

Ensure proper ground exists before use

Fig. 12

DO NOT CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER PLUG.

A.SITUATIONS WHERE THE APPLIANCE WILL BE DISCONNECTED ONLY OCCASIONALLY:

TEMPORARY METHOD

Adapter plug

Metal screw

Receptacle cover

Because of potential safety hazards, we strongly discourage the use of an adapter plug. However, if you wish to use an adapter, a TEMPORARY CONNECTION may be made. Use UL-listed adapter, available from most local hardware stores (Fig. 13). The large slot in the adapter must be aligned with the large slot in the receptacle to assure a proper polarity connection.

CAUTION: Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal, and not insulated, and the wall receptacle is grounded through the house wiring.

The customer should have the circuit checked by a qualified electrician to make sure the

receptacle is properly grounded.

Disconnect the power cord from the adapter, using one hand on each. Otherwise, the adapter ground terminal might break. DO NOT USE the appliance with a broken adapter plug.

B.SITUATIONS WHERE THE APPLIANCE WILL BE DISCONNECTED OFTEN.

Do not use an adapter plug in these situations. Unplugging the power cord frequently can lead to an eventual breakage of the ground terminal. The wall power outlet should be replaced by a three-slot (grounding) outlet instead.

USE OF EXTENSION CORDS

Because of potential safety hazards, we strongly discourage the use of an extension cord. However, if you wish to use an extension cord, use a CSA certified/UL-listed 3-wire (grounding) extension cord, rated 15A, 125V.

Troubleshooting Tips save time and money!

Review the chart below first and you may not need to call for service.

Normal Operation

•You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.

•You may hear the relay click when the compressor cycles on and off.

•Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit.

•The fan may run even when the compressor does not.
