This document describes the Rohnson R-8801 Bladeless Tower Air Cooler 4-in-1, a versatile appliance designed to provide cooling and air circulation. The manual emphasizes safety, proper installation, operation, and maintenance to ensure optimal performance and longevity of the device.
Function Description
The Rohnson R-8801 is a bladeless tower air cooler that offers a 4-in-1 functionality, suggesting it can act as a fan, air cooler, humidifier, and potentially an air purifier or ionizer, though the latter is explicitly mentioned as an "anion" function. Its primary purpose is to cool and circulate air within a room, providing a comfortable environment. The bladeless design contributes to safety and a sleek aesthetic. The air cooler operates by pumping water against a water filter, creating cold and moist air that is then blown out into the room. This evaporative cooling process is enhanced by the option to use cool packs for additional cooling.
Usage Features
The R-8801 is designed for ease of use, featuring both a control panel on the appliance and a remote control for convenient operation.
- ON/OFF Function: The appliance is switched on and off using a dedicated button on both the control panel and the remote.
- Speed Settings: It offers 12 different speed settings, allowing users to adjust the airflow intensity according to their preference. The selected speed is displayed on the screen panel.
- Timer Function: A timer button enables time-controlled operation, allowing users to set the appliance to switch off automatically after a period ranging from 1 to 12 hours, in one-hour increments. This feature is useful for energy saving and convenience, especially during sleep.
- Cooling Function: Activating the COOLING button initiates the evaporative cooling process. It's crucial to ensure the water level in the tank is above the MIN mark for this function to work effectively. The appliance starts pumping water to create a cool, moist breeze.
- Oscillation (SWING) Function: The SWING button activates horizontal oscillation, distributing the blown-out air to the left and right across the room. This ensures wider coverage and more even cooling. Pressing the button again deactivates this function.
- Anion Function: The "anion" button starts a function that likely releases negative ions into the air, which can contribute to air purification and a fresher indoor environment.
- Light Function: A dedicated light button turns on a "decoration light," adding an aesthetic element to the appliance.
- Water Tank: The appliance features a water tank at the bottom, which needs to be filled with clean water. There are MIN and MAX marks to guide proper filling, preventing damage to electronic parts from overfilling and ensuring the pump functions correctly.
- Cool Packs: The R-8801 comes with two cool packs that can be filled with water, frozen for 3-4 hours, and then placed in a compartment on top of the appliance. These cool packs enhance the cooling effect, providing colder air.
- Remote Control: A remote control is included for convenient operation from a distance. It requires an AAA battery (not included) and should be pointed directly at the front of the appliance without obstacles. Users are advised to handle the remote carefully, avoiding direct sunlight and heat sources.
Maintenance Features
Regular maintenance is crucial for the efficient and safe operation of the Rohnson R-8801.
- General Cleaning: Before any cleaning, the appliance must be switched off, unplugged from the mains power supply, and allowed to cool for a few minutes. The housing should be cleaned with a moderately damp cloth and then wiped dry. Harsh chemicals like benzene, alcohol, or solvents, as well as insecticides, should never be used.
- Cover Grille Cleaning: The cover grille should be cleaned weekly to ensure efficient operation. This involves removing two locking screws with a screwdriver, detaching the grille, and using a vacuum cleaner to remove accumulated dust. If the grille is very dirty, it can be immersed in warm water (not exceeding 40 °C) and rinsed several times, then allowed to dry completely before reinstallation. The appliance should never be used without the cover grille.
- Water Tank Emptying and Cleaning: It is recommended to empty and clean the water tank weekly during use. This involves switching off and unplugging the appliance, removing the water tank from its safety holder, and then forcefully pressing clips to release the water pump. Once the pump is released, the tank can be completely removed. The tank should be cleaned inside and out with a soft cloth immersed in soapy water, then rinsed with warm, clean water, and allowed to dry completely before reassembling the water pump and reinserting the tank.
- End-of-Season Maintenance: At the end of the season, the appliance should be switched off and unplugged. The water tank should be emptied and cleaned carefully. The cover grille should also be cleaned and reinserted after drying. Finally, the appliance should be packed away and stored in a cool, dry, childproof location.
- Pre-Season Inspection: Before starting use for a new season, it's important to verify that the power supply cable is in order and that the earthing is functioning correctly. All installation and safety instructions should be followed carefully.
- Troubleshooting: The manual provides a troubleshooting guide for common issues such as the air cooler not switching on (power failure, not connected, empty water tank), working only for a short time (blocked air outlet), unpleasant odor (dirty air filter or water tank), or being very loud (not on a level floor). This guide helps users identify and rectify problems before contacting customer service.
The manual emphasizes several critical safety instructions:
- Always read all instructions carefully before use.
- Use the fan only as described in the manual to avoid fire, electrical shock, or injury.
- Ensure the FAN is undamaged upon unpacking; contact the supplier if damaged.
- Keep packaging parts away from children.
- Verify voltage matches home mains supply.
- Exercise extreme caution when used near children or invalids, or when left unattended.
- Avoid extension cords due to overheating risk.
- Always grasp the plug, not the cord, to disconnect from power.
- Do not insert objects into the FAN or block/tamper with it during operation.
- Unplug the FAN when not in use and never leave it unattended.
- Not for use in wet/damp locations; keep away from bathtubs or water containers.
- Do not use outdoors.
- Disconnect from mains power before servicing or maintenance.
- The main power switch and On/Off switch are not sole means of disconnecting power; always unplug the cord.
- Keep the fan clean and maintained by authorized service agents.
- Use only recommended parts.
- Store in a safe, dry, childproof location when not in use.
- Damaged supply cords must be replaced by the manufacturer, service agent, or similarly qualified persons.
- Children aged 8 and above, and persons with reduced capabilities, can use the appliance with supervision and understanding of hazards. Children should not play with it or perform cleaning/maintenance without supervision.
- High humidity can encourage biological growth; reduce appliance output or use intermittently if dampness occurs.
- Do not allow absorbent materials (carpeting, curtains) to become damp.
- Unplug during filling and cleaning.
- Empty and clean before storage and next use.
- Unplug from outlet when not in use or cleaning.
- If the supply cord is damaged, it must be replaced by the manufacturer or service agent to avoid hazards.
