Before Operation

Owner’s Manual 7

ENGLISH

Before Operation

1. Contact an installation specialist for installation.

2. Plug in the power plug properly.

3. Use a dedicated circuit.

4. Do not use an extension cord.

5. Do not start/stop operation by plugging/unplugging the power cord.

6. If the cord/plug is damaged, replace it with only an authorized replacement part.

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.

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.

For repair and maintenance, contact your authorized service dealer.

Electrical Safety

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 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.

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

A. SITUATIONS WHEN THE APPLIANCE WILL BE

DISCONNECTED OCCASIONALLY:

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. The large slot in the adapter must be aligned with the large slot in the receptacle to assure a proper polarity connection.

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 WHEN 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 at 15A, 125V.

Installation

Remove packing materials from the wall sleeve and tape from the air conditioner.

INSTALLATION REQUIREMENTS

If you use an existing wall sleeve, you should

measure its dimensions. Install the new air conditioner according to these installation instructions to achieve the best performance. All wall sleeves used to mount the new air conditioner must be in good structural condition and have a rear grille to securely attach the new air conditioner. (FIG. 1)

With the HCI sleeve(optionally supplied with your unit), you can maintain the best performance of the

new air conditioner. (FIG. 2)

ELECTRICAL SERVICE

Check your available electrical service. The power supply available must be the same as that shown on the unit nameplate (found on left side of cabinet).

All models are equipped with a 3-prong service plug to provide proper service and safe positive grounding. Do not change plug in any way. Do not use an adapter plug. If your present wall outlet does not match your plug, call a qualified electrician to make the necessary corrections. SAVE CARTON for storage and this OWNER'S MANUAL for future reference. The carton is the best way to store unit during winter or when not in use.

ITEMS IN INSTALLATION HARDWARE

You may not need all par ts in the kit. Discard unused parts

HOW TO INSTALL

Identify the existing wall sleeve before installing the unit from the listed below.

All wall sleeves used to mount the new Air Conditioner must be in sound structural condition and have a rear grille that securely attaches to sleeve, or rear flange that serves as a stop for the Air Conditioner.

Remove old air conditioner from existing wall sleeve.

Clean the interior of an existing sleeve. (Do not disturb seals.)

Wall sleeve must be securely fastened in wall before installing the air conditioner. Use the nails or screws through sleeve into wall, if needed. Repaint sleeve if needed.

Prepare the wall sleeve for installation of the unit. If you plan to use your existing wall sleeve, and it is not HCI, use procedure B or C below.

Install new unit into wall sleeve.

When installation is completed, replacement unit MUST have a rearward slope as shown. To achieve 1/4" slope, remove the backing from the 11-13/16" shim strips and attach them as shown below in Fig. 3. Place the higher portion of shim to the front of the rib on base of wall sleeve.

Air Filter Cleaning

How to Attach Front Grille to Cabinet

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

The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the filter will build up and block the airflow.This reduces the cooling capacity and also causes an accumulation of frost on the cooling coils.

If the filter becomes turn or damaged you should replace immediately. Replacement filters are available from your salesperson, dealer, and the authorized customer service centers.

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

2. Remove the air filter from the front grille assembly 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 completely. Replace the filter.

The front grille can be removed for cleaning or to check the model and serial numbers. For your safety, you should attach the front grille as the following procedures.
