This document describes the RM-3701 Air Cooler, a device designed to provide cooling and humidification with remote control functionality.

Function Description:

The air cooler operates by drawing in air, passing it through a wet curtain paper, and then blowing out cooler, humidified air. It features multiple speed settings (low, medium, high) and can operate in cooling (humidifying) mode. A swing function is available to distribute air more widely. The device also includes a timer function, allowing users to set it to turn off automatically after a specified duration. For enhanced cooling, the air cooler can utilize frozen ice boxes placed in the water tank.

Important Technical Specifications:

The manual does not explicitly list detailed technical specifications such as power consumption, voltage, or water tank capacity in a dedicated section. However, it mentions that users should check if their voltage is compatible with the nameplate for the air cooler. It also indicates that the chosen socket should be rated for more than 10A current.

Usage Features:

ON/OFF (Speed) Button:
- Pressing once activates low speed.
- Pressing twice activates medium speed.
- Pressing three times activates high speed.
- Pressing four times turns the air cooler off.
Cooler (Humidifying) Button:
- Pressing once activates cooling (humidifying) mode, indicated by a red "Cooler" light.
- Pressing twice activates humidifying mode, indicated by a blue "Humidifying" light.
- Pressing three times turns off the cooling/humidifying function.
Swing Button:
- Pressing once activates the swing function.
- Pressing twice deactivates the swing function.
Timer Button:
- The timer allows setting the device to turn off after specific intervals:
  - 0.5 hours (0.5H indicator)
  - 1 hour (1H indicator)
  - 1.5 hours (1H and 0.5H indicators)
  - 2 hours (2H indicator)
  - 2.5 hours (2H and 0.5H indicators)
  - 3 hours (1H, 2H, and 0.5H indicators)
  - ...and so on, up to 7.5 hours (4H, 2H, 1H, and 0.5H indicators).
- Pressing the button a sixteenth time disables the timer function.
Water Injection:
- The water tank is pulled out from the bottom back of the air cooler.
- Water should be injected until the tank is about 1/3 full.
- The water level must always be below "MAX" and above "MIN" when cooling/humidifying.
Using Ice Boxes:
- Ice boxes should be frozen in a fridge.
- Once frozen, they are placed into the water tank after pulling it out.
- The air cooler typically comes with two ice boxes for continuous use.
- When ice boxes are added, the water level should still be less than "MAX".

Maintenance Features:

General Precaution: Before any cleaning or maintenance, always pull off the plug and cut off the power. No part of the control panel should come into contact with water.
Clean Air Filter:
- Pull off the plug.
- Remove the air filter holder by hand.
- Clean the air filter with a neutral cleaner and a soft brush.
- Rinse with clean water.
- Reinstall the air filter.
Clean Wet Curtain Paper:
- Pull off the plug and remove the air filter.
- Take out the wet curtain paper from the air cooler.
- Clean it with fair water, a cleaner, and a soft brush.
- Reinstall the wet curtain paper smoothly to avoid leaks.
Clean Water Tank:
- Pull off the plug and take out the water tank.
- Wipe off scale inside the tank with a towel and a little cleaner.
- Clean the tank with fair water.
- Reinstall the water tank.
Clean Housing:
- Wipe off the housing with a neutral cleaner and a soft cloth.

Safety Warnings:

Do not block the wind inlet with walls, curtains, or other objects, as this will affect airflow and cooling efficiency.
Ensure the power cord and plug are not damaged or twisted to prevent poor contact. Damaged cords must be replaced by the manufacturer or qualified personnel.
Do not cover the outlet or place the air fan too close to the socket.
Use a socket rated for more than 10A and avoid sharing it with other appliances.
Never insert hands or foreign objects into the air cooler's network, especially when it is working (pay special attention to children).
The appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless supervised or instructed by a responsible person.
Children should be supervised to ensure they do not play with the appliance.
Always turn off the power before pulling out the plug. Do not pull the power cord itself; pull the power plug to avoid short-circuits, fire, or electric shock.
Do not pull the power plug with wet hands to avoid electric shock.
Unplug the device when not in use.
Do not place the working air cooler on an uneven or declining surface.
Do not operate the air cooler outdoors or near baths, showers, or pools.
Always ensure the water level is between "MIN" and "MAX" when using cooling/humidifying functions.
Do not lean or bump the air cooler when the water tank is filled.
Do not place anything on top of the air cooler.
Do not cover the outlet and inlet of the air cooler.
