Adding Water and Using the Ice Packs

You can add water and ice packs to your evaporative air cooler to lower

the temperature of the air being blown through the front air vent. Adding

ice packs to the water tank will make the air flow temperature colder.

To add water to the unit follow the steps below:

1. Unplug the power plug from the outlet.

2. Turn the lock knob to the left to unlock the water tank.

3. Slide the water tank out. The water pump will swing up.

4. Pour water into the tank.

5. Carefully slide the water tank back in. There may be a slight

resistance when inserting the water tank. The water pump will

swing down and be submerged into the water.

6. Turn the lock to prevent the water tank from sliding out.

7. Plug the power plug to the power outlet.

An ice pack can help lower the water temperature in the water

tank to allow colder air to blow out from the unit.

To use the ice pack:

1. Place the ice pack in your freezer.

2. After the ice pack is frozen, open the water tank and place it

inside the water tank.

Note: Do not overfill the

water tank. The water level

should be kept below the

“MAX” indicator line.

Operating Instructions

After connecting the air cooler’s power plug to an outlet, the unit will

be ready to be operated.

Control Panel Operation

To power the unit on, switch the Timer Dial to the “ON” position.

Press on the LOW, MED, or HI buttons to set the fan speed.

To turn the unit off, press the OFF button or turn the dial to the

“OFF” position.

The Cool button is used to turn the water pump on or off. The unit

pumps water from its water tank over the evaporative wick. As air is

drawn past this water, the endothermic effects of evaporation result

in cooling.

Caution: Never run the unit in cool mode if the water tank is

empty. This may cause damage to your water pump.

The Swing button is used to turn the oscillation function on or off.

The louvers will automatically direct airflow from left to right when

the Swing button is pressed.

The timer can be used to turn the unit off automatically. The timer

is adjustable up to 2 hours. To use the timer, simply turn the dial to

the 30, 60, 90 or 120 marks. The unit will run for the amount of time

that was set and then it will shut off.

Press the LOW, MED, or HI buttons to adjust the fan speed.

Louver Control

Press the SWING button to start the vertical louvers moving from

side to side. To stop the louvers, press the SWING button again.

You can change the air direction up or down by manually adjusting

the horizontal louvers.

Notes: Do not allow the air intake to be near walls or curtains,

otherwise the wind and cooling effect may be reduced because of

blocked air flow. Do not expose the unit to direct sunlight.

1. Unlock the water tank.

2. Remove the water tank and drain the water.

3. Dry the water tank with a soft cloth.

4. Reinsert the water tank.

5. Lock the water tank.

Cleaning and Maintenance

Clean the air cooler, pre-filter and water tank regularly to maximize

performance and efficiency, and prolong the unit’s life. Be sure to

always unplug the air cooler from the power outlet before cleaning.

Use a soft dry cloth to wipe the body clean. If necessary, use

lukewarm water to dampen a cloth to clean the unit. Use a soft

bristle brush and vacuum cleaner to clean between the air vents.

Never use abrasive chemicals, volatile substances, gasoline,

detergents, chemically treated cloths, or other cleaning solvents

that may damage the exterior.

Never spray water directly on the unit.

Depending on environmental conditions, the water tank may require

cleaning as frequent as every 2 weeks up to every 2 months. If the

tank becomes dirty, develops mildew, or acquires hard water

deposits, unplug the unit, remove the water tank and carefully clean

the inside of the tank with a soft cloth and a mild soap and water

solution. Rinse out the solution and drain the water as best as you

can.

You may also rinse the water tank with a solution of 2 tablespoons

vinegar in ½ gallon of water.

If you are not going to be using the unit for an extended period of

time, follow the instructions below before storing your unit:

1) Drain all the water from the unit’s water tank. Operate the unit in

fan mode for a few hours to thoroughly dry any moisture left on the

inside of unit.

2) Power off the unit and unplug it.

3) Clean the unit, pre-filter and water tank.

4) Carefully wind the power cord.

Pre-filter and Evaporative Wick Maintenance

It is necessary to clean the pre-filter and evaporative wick periodically.

Depending on the environment, the pre-filter and evaporative wick may

need to be cleaned on a weekly or biweekly basis. Note: If the pre-filter is

exceptionally dirty, it will restrict the air flow the unit will be able to project.

Follow the steps below to remove and clean the pre-filter and evaporative

wick.

1. Slide the pre-filter straight up.

Use a vacuum cleaner with a brush attachment or tap the pre-filter lightly

to remove loose dust and dirt, then rinse thoroughly under lukewarm

running water (below 104°F). You may use a mild soap and water

solution if needed. Allow the pre-filter to air dry completely before

reinstalling.

2. After removing the pre-filter, remove the evaporative wick by pressing

the locking tabs inward towards the center of the unit. Gently pull the wick

out to remove it. Wash the evaporative wick with running water only.

Depending on environmental conditions and amount of use, you may

need to replace the evaporative wick after every season of use.

Caution: Do not use pressure washers to clean the wick.
