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.

Air Filter Cleaning

Vent Filter

TURN OFF THE AIR CONDITIONER 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. Remove the air filter from the front grille assembly by

pulling the air filter up slightly.

2. Wash the filter using lukewarm water below 104° F(40°C).

3. Gently shake the excess water from the filter completely.

Reinstall the filter.

Before cleaning the vent filter, disconnect power to the

unit by unplugging the power cord at the wall outlet or

subbase, or disconnect power at the fuse box or circuit

breaker. If unit is operated with vent door closed, the

vent filter does not need to be cleaned.

1. Remove the front grille as described in front grille

Removal.

2. Remove the 4 screws securing the chassis to the

wall sleeve with a Phillips-Head screwdriver.

3. Slide the chassis out of the wall sleeve far enough so

that the vent filter is accessible as shown in Figure A.

4. Remove the vent filter by unscrewing the two screws

at the top of the filter and gently pulling the filter away

from the partition panel. Refer to Figure B.

5. Clean and reinstall the filter by reattaching the hook

to the bottom of the vent door and replacing the two

screws, slide the chassis back into the wall sleeve,

secure it in place with 4 screws and reinstall the

Chassis

Front Grille

Compressor / Fan Motor

The chassis must be cleaned every four months or more often as the atmospheric conditions

require. Use water and detergent to clean the basepan, center partition and coils. The use of harsh

cleaning materials may cause a deterioration of the coil fins or endplates. Do not use a high

pressure cleaner as it could cause severe damage to the PTAC fins and coils. A hose is okay to use

to clean the coils, but make sure to cover the control with a blanket or plastic bag to keep it dry.

The base pan may overflow due to high humidity.

To drain the excess water, remove the drain cap

from the back of the unit.

The compressor and fan motor are hermetically sealed, permanently lubricated, and require no

additional oiling.

The Front Grille and discharge air grille can be cleaned with a mild soap or detergent. Under no

circumstances should hydrocarbon based cleaners (e.g. acetone, benzene, naphtha, gasoline, etc.)

be used to clean the front or air grilles.

Use care when cleaning the control area. Do not use an excessively wet cleaning cloth.
