Introduction
This manual provides comprehensive instructions for the safe installation, operation, and maintenance of your SOSTOO Water Cooler Dispenser. This appliance is designed to provide convenient access to both hot and cold water from 3 or 5-gallon top-loading water bottles. Please read this manual thoroughly before initial use and retain it for future reference.
Safety Instructions
- Electrical Safety: Ensure the power outlet matches the dispenser's voltage (110V/60Hz). Do not use extension cords. Always unplug the dispenser before cleaning or maintenance.
- Water Level: Always ensure the water bottle is properly installed and the machine is filled with water before plugging it in and turning on the heating function. Operating the heating element without water can cause damage to the appliance and poses a fire risk.
- Child Safety Lock: The hot water tap is equipped with a child safety lock. To dispense hot water, simultaneously press the safety lock and the hot water button. This prevents accidental burns.
- Placement: Place the dispenser on a firm, level surface. Avoid direct sunlight, heat sources, or areas with high humidity. Ensure adequate ventilation around the unit.
- Cleaning: Use only mild detergents and a soft cloth for cleaning. Do not immerse the appliance in water.
- Damage: Do not operate the dispenser if the power cord or plug is damaged, or if the appliance has been dropped or damaged in any way. Contact customer support for assistance.

Setup

- Initial Flush (Recommended): Before plugging in, dispense several cups of water from both the hot and cold faucets to ensure water flows freely and to flush out any manufacturing residue.

Operating Instructions
Powering On
- After plugging in the unit, locate the power switches on the back of the dispenser.
- The red switch controls the heating function. Flip it to the 'ON' position for hot water. The heating process typically takes 3 to 5 minutes.
- The green switch controls the cooling function. Flip it to the 'ON' position for cold water. Chilled water will be ready in approximately 40 to 60 minutes.

Dispensing Water
