Probleemoplossing

Please read and understand these safety instructions. Incorrect use can cause injury and will void EUROM's warranty.

• Children of less than 3 years should be kept away unless continuously supervised.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
  •Children shall not play with the appliance.
• Cleaning and maintenance shall not be made by children without supervision.
• If the supply cord (Type USB-A / USB-C) is damaged, it must be replaced by an original replacement cable.

Safety warnings powerbank (powerbank not included)

• The device will only work without interruption when the powerbank has an output of 5 Volt and minimum 2 Ampere.
• Never connect the device on a voltage higher than 5 Volt.
• Do not use or store the powerbank near heat sources such as fire or heaters.
• Do not leave the powerbank in an enclosed vehicle.
• The powerbank gets hot during charging, so make sure the powerbank can safely release this heat to the surrounding air during charging.
• Do not charge the powerbank when the device is used with the power bank at the same time.
• Charge the powerbank only with the supplied charging cable.
• Keep the powerbank away from water or humid environments.
• Do not disassemble, damage, jolt or pierce the powerbank.
• Do not use the powerbank below 0^ Celsius or above 50^ Celsius, otherwise the charge and discharge function of the powerbank will be disabled due to an internal safety mechanism.
• Keep the powerbank away from children.
• Recommended operating and storage temperature for the powerbank: 10^ - 30^ Celsius.
• The powerbank's optimal state of charge is between 30% and 70% .
• If the powerbank is not used for a long time, store it with a charge status of about 70% and charge and discharge it every 3-6 months and place it in a cool, dry place. Otherwise, the performance of the powerbank will decrease or the powerbank's lifespan will be shorter.
• Never try to open the powerbank. In case of misuse, the battery might emit a liquid. If you come in contact with this unintentionally, rinse the affected area with water. If the liquid comes in contact with eyes, then rinse with water and seek medical assistance. Liquid from a battery can cause irritation or burns.
• This product must be removed in a correct manner, taking environmental considerations into account. Return this product to your local dealer or to the local recycling station where the powerbank is recycled or disposed of in a correct manner.
• Never burn the powerbank, even if it is damaged and can no longer be charged. Batteries explode when they are burned.

Description

The Coolstar Portable is a powerbank-operated air-cooler. 'Warm' air is drawn into the cooler and enters the Honeycomb Cooling Pad. Water pumped from the water tank pours over the Honeycomb Cooling Pad. As the warm air passes through the Honeycomb Cooling Pad, the water absorbs the heat, naturally cooling and humidifying the air. A fan propels the cooled air

out into the room. This no-compressor system cools naturally, efficiently and inexpensively. The air cooler can cool the air up to 3 degrees.

Operation

CAUTION

Make sure that the USB-A / USB-C cord does not protrude through the fan grille.

There are 4 ways to power the Coolstar Portable:

1. By powerbank

1. Connect the USB-A connector of the USB-A / USB-C cord to the USB-A output port of the powerbank.

2. Connect the USB-C connector of the USB-A / USB-C cord to the USB-C port on the device.

3. Place the powerbank on the backside of the device. Never place the powerbank on the frontside because in COOL mode moist air comes out of the front grille.

2. Via 220/240 Volt 50 Hz socket

Use a USB-A mains adapter (not provided), which is intended for use with a household socket of 220-240 Volt / 50 Hz, output voltage of 5 Volt and an output capacity of minimum 2 Ampere. Never try to use a USB-A mains adapter with other voltages. The connection voltage and the frequency stated on the USB-A mains adapter must correspond with those of the socket that you use. The electrical installation must be equipped with a residual-current circuit breaker of 30mA.

1. Connect the USB-A connector of the USB-A / USB-C cord to the USB-A output port of the adapter.

2. Connect the USB-C connector of the USB-A / USB-C cord to the USB-C port of the device.

3. Connect the USB-A mains adapter to a suitable household socket.

3. Via a USB car adapter (the cigarette lighter)

Use a USB-A car adapter with an output voltage of 5 Volt and a output capacity of minimum 2 Ampere. Never try to use a USB-A car adapter with other voltages. The connection voltage

stated on the USB-A car adapter must correspond with those of the socket that you use and the electrical installation must be equipped with a circuit breaker.

1. Connect the USB-A connector of the USB-A / USB-C cord to the USB-A output port of the adapter.
2. Connect the USB-C connector of the USB-A / USB-C cord to the USB-C port of the device.
3. Connect the USB-A car adapter to a suitable cigarette lighter socket.

4. Via a 5 Volt USB-A port (e.g. a laptop or computer)

Use a USB-A port with an output voltage of 5 Volt and a output capacity of minimum 2 Ampere. Never try to use other USB-A ports.

1. Connect the USB-A connector of the USB-A / USB-C cord to the USB-A output port.
2. Connect the USB-C connector of the USB-A / USB-C cord to the USB-C port on the device.

Turning on/off

1. Turn on the powerbank.
2. Press the ON/OFF button to turn on the device.
3. Press the ON/OFF button again to turn off the device.

Wind speed

The fan has 2 wind speeds which can be selected.

1. Turn on the device.
2. Select the HIGH or LOW wind speed button.

Cooling

1. Press the COOL button to enter the COOL mode.
2. Blue light is illuminated when water tank is filled.
3. Red light is illuminated when water tank is empty.

When the COOL mode is activated, the pump inside the water tank will pump water to saturate the cooling pad. Heat that flows through the cooling pad will exchange with water and cool the air flowing through the cooling pad to lower the temperature.

Cleaning and maintenance

CAUTION

• Be sure that the device is disconnected from the power source before performing cleaning and maintenance work.
• Clean the inside from the water tank and remove sediment from the water tank.
• Never immerse the device in water or any other liquid.
• Never use abrasive, aggressive, or flammable cleaning agents such as bleach or alcohol to clean any part of the device.

• Regularly clean the outside of the fan to prevent dust from collecting.

• Pull the water tank backwards (Figure 10, pos. 3) and drain the water from the water tank.

• Clean the inside of the water tank and remove sediment from the water tank.

• Close the water tank.

• Remove the back shutter (Figure 10, pos. 2).

• Clean the cooling pad (Figure 10, pos. 1) with clean water and wipe dirt of with a soft brush.

• Place the cooling pad and the back shutter back into position.
