ENGLISH

Before to Operation

1. Plug in the power plug properly.

2. Use a dedicated circuit. Overloading the line could create a fire hazard.

3. Do not use an extension cord. See page 10 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.

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.

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.

ENGLISH

WARNING: This appliance must be properly grounded.

The power cord of this appliance is equipped with a three-prong grounding plug.
To minimize the risk of electric shock, use the plug with a standard three-slot
grounding wall power outlet. If the power outlet does not include a grounding slot,
have a qualified electrician replace the outlet before you use the room air
conditioner.

WARNING: Changing the outlet without making the appropriate wiring
changes will create an unsafe condition that could result in fire or
electrical shock. Refer all such work to a licensed and qualified
electrician.

WARNING: Do not cut or remove the grounding prong from the power
plug.

WARNING: 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.

WARNING: If you have any doubt whether the air conditioner is

properly grounded, have the wall receptacle and circuit checked by a
qualified electrician.

Electrical Safety

Preferred method

Ensure proper ground

exists before use

PTAC DIRECT SALES [phone]

10 Room Air Conditioner

We strongly discourage the use of an adapter due to potential safety hazards.
For temporary connections, use only a UL-listed adapter, available from most
local hardware stores.Ensure that the large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.

To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the power cord as
this can lead to eventual ground terminal damage.

WARNING: Never use the appliance with a broken adapter.

We strongly discourage the use of an extension cord due to potential safety
hazards. For temporary situations, use only CSA certified and UL listed 3-wire
grounded extension cords, rated 15 A, 125 V.

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.

1. Pull down front grille from the cabinet top.

2. Push front grille’s tips toward the cabinet in
order to insert front grille’s tabs into the
cabinet.

3. Open the inlet grille.

4.Tighten the screw through the front grille into
the plate of control box.

5. Close inlet grille.
