This document describes the Homemaker evaporative air cooler, model FSH-90R, an appliance designed to provide cooling and air circulation in indoor environments. The manual outlines its key features, operational instructions, and important safety guidelines, as well as care and cleaning procedures.
Function Description
The Homemaker evaporative air cooler operates on the principle of evaporative cooling, which involves drawing in warm, dry air, passing it over water-saturated pads, and then releasing cooler, humidified air into the room. This process not only lowers the air temperature but also adds moisture to the air, making it particularly effective in dry climates. Unlike traditional air conditioners that use refrigerants, evaporative coolers utilize water, making them a more energy-efficient and environmentally friendly cooling solution. The device is equipped with a fan that circulates the air, and its cooling effect is enhanced by the evaporation of water from an internal tank.
Usage Features
The evaporative air cooler is designed for ease of use, offering both touch panel controls on the unit itself and a remote control for convenient operation from a distance.
- 3 Speed Fan Settings: Users can select from low, medium, or high fan speeds to adjust the intensity of the airflow according to their comfort preferences. This allows for flexible cooling, from a gentle breeze to a more powerful air circulation.
- Remote Control Operation: A dedicated remote control provides full functionality, mirroring the controls on the main unit. This includes power on/off, adjusting fan speed, setting the timer, controlling swing, and selecting fan type. The remote requires two AAA batteries, which are not included.
- 8.5 Litre Water Tank: The cooler features a large 8.5-litre water tank, reducing the frequency of refills. For optimal cooling performance, users are advised to fill the tank with cold or iced water up to the 'max' level indicated.
- Touch Panel Control: In addition to the remote, the unit has an intuitive touch panel on its top surface. This panel allows direct control over all functions, including power, cool air function, fan speed, timer, swing, and fan type.
- Oscillating Vertical Louvres: The cooler includes oscillating vertical louvres that automatically move from side to side. This feature helps to distribute the cooled air more widely and evenly across the room, preventing static airflow and enhancing overall comfort.
- Adjustable Horizontal Louvres: In addition to the automatic vertical swing, the horizontal louvres can be manually adjusted. This allows users to direct the airflow vertically, further customizing the direction of the cooled air to specific areas within the room.
- Castor Wheels for Easy Mobility: The unit is fitted with swivelling castor wheels on its base. These wheels enable effortless movement of the cooler from one room to another, providing flexibility in placement and ensuring cooling where it's needed most.
- Cool Air Function: A dedicated 'Cool' button activates the evaporative cooling function, initiating the water pump to saturate the cooling pads and begin the cooling process. Pressing this button again will stop the flow of cool air.
- Timer Function: The cooler includes a timer feature with settings for 0.5, 1, 2, or 4 hours. The timer can be set in half-hour increments up to a maximum of 7.5 hours. When the timer is active, an LED indicator illuminates, and the unit will automatically turn off once the set time has elapsed. This is useful for programming the cooler to operate for a specific duration, such as overnight or for a short period.
- Fan Type Selection: Users can choose between three fan types: Normal, Natural, and Sleep.
- Normal: Provides a consistent airflow at the selected speed (low, medium, or high). No specific light is lit when this mode is active.
- Natural: Simulates a natural breeze by varying the fan speed, offering a more dynamic and less monotonous airflow.
- Sleep: This mode uses the natural fan type and gradually lowers the fan speed over time before eventually turning the unit off. At high speed, it operates at high for 30 minutes, then medium for 30 minutes, and finally drops to low natural wind until it turns off or the timer expires. Similar patterns apply for medium and low initial speeds, ensuring a gentle transition to sleep.
- Memory Function: The evaporative cooler features a memory function. When the unit is turned off, it remembers the last used settings (speed, swing, fan type, etc.) and will resume operation with these same settings when switched back on. This eliminates the need to reconfigure preferences each time the unit is used.
Maintenance Features
Proper care and cleaning are essential for maintaining the efficiency and longevity of the Homemaker evaporative air cooler.
- Disconnection Before Cleaning: Before any cleaning or maintenance, it is crucial to ensure the appliance is disconnected from the power supply and switched off. This is a fundamental safety precaution to prevent electric shock.
- Non-Dismantlable Design: The appliance is not designed to be dismantled by the user without special tools. Users are explicitly advised not to attempt to repair, disassemble, or modify the unit themselves, as this could damage the appliance and void the warranty.
- Simple External Cleaning: Cleaning the exterior of the unit should be done with a slightly damp, soapy cloth. It is important to ensure the cloth is not excessively wet to avoid leaving water behind, which could potentially damage internal components. After wiping with the soapy cloth, any wet spots should be dried with a paper towel.
- Safety Grill: The unit features a safety grill to protect internal components and prevent users from inserting foreign objects. This design helps maintain the integrity of the appliance and ensures user safety.
- Water Tank Management: Regular monitoring of the water level in the 8.5-litre tank is necessary. While not explicitly detailed as a "maintenance feature," the need to add water and potentially clean the tank (though not detailed in this excerpt) is implied for continuous operation and hygiene.
- Power Plug Removal: The power plug must always be removed from the power socket before any cleaning, servicing, maintenance, or when moving the appliance. This reinforces the safety-first approach to handling the device.
The Homemaker evaporative air cooler is designed to be a user-friendly and effective cooling solution, particularly in dry climates, offering a range of features for customized comfort and straightforward maintenance.
