Setup and Installation
The Oasis POU1CCTHS is a Point-of-Use (POU) countertop water cooler designed to connect directly to your existing cold water line. Professional installation is recommended for connecting to the water supply.
Unpacking
- Carefully remove the cooler from its packaging.
- Inspect the unit for any shipping damage. If damaged, do not operate and contact your supplier.
- Place the cooler on a flat, stable, and level countertop surface. Ensure there is adequate space around the unit for ventilation (at least 4 inches from walls).
Water Line Connection
- Locate a suitable cold water supply line near the installation area.
- Install a shut-off valve and a water filter (if desired, not included) on the cold water line.
- Connect the water cooler's inlet to the filtered cold water supply line using appropriate plumbing fittings. Ensure all connections are secure and leak-free.
- Once connected, slowly open the water supply valve to fill the cooler's reservoirs.
Initial Flushing
- Before plugging in the unit, dispense several cups of water from both the hot and cold spouts until water flows smoothly and without air bubbles. This flushes out any manufacturing residue and air from the system.
- Once flushed, plug the cooler into a grounded 110-120V AC electrical outlet.

Cold Water Dispensing
- Place a cup or container under the blue (cold water) spout.
- Press the cold water lever or button to dispense cold water. Release to stop.
- The cold water reservoir has a 1-gallon capacity. The cold water temperature is controlled by an adjustable thermostat located on the rear of the unit, allowing you to customize the chill level.
Hot Water Dispensing

Power and Indicators
- The unit will have indicator lights (e.g., for power, heating, cooling) to show its operational status. Refer to the specific labels on your unit.
- Allow sufficient time for the unit to reach desired hot and cold temperatures after initial setup or after being unplugged.
Maintenance and Cleaning
Regular maintenance ensures optimal performance and hygiene of your water cooler.
Drip Tray Cleaning
- The drip receptor is durable and dishwasher safe. It lifts out easily for cleaning.
- Empty and clean the drip tray regularly to prevent overflow and bacterial growth.
Exterior Cleaning
- Unplug the unit before cleaning.
- Wipe the exterior surfaces with a soft, damp cloth. For stubborn stains, use a mild, non-abrasive cleaner.
- Do not use harsh chemicals or abrasive pads, as they can damage the finish.
Internal Cleaning (Sanitization)
It is recommended to sanitize the internal water reservoirs and lines every 3-6 months, or more frequently depending on water quality and usage. Consult a qualified technician or refer to specific sanitization kits available for water coolers.
- Always unplug the unit and drain all water from the reservoirs before internal cleaning.
- Follow the instructions of your chosen sanitization solution carefully.
- Thoroughly rinse the system with clean water after sanitization to remove any cleaning solution residue.
Troubleshooting
If you experience issues with your water cooler, refer to the following common problems and solutions. If the problem persists, contact customer support.
| Problem | Possible Cause | Solution |

| No hot or cold water | Unit unplugged; power switch off; water supply off; thermostat setting. | Ensure unit is plugged in and power switch is on. Check water supply valve. Adjust cold water thermostat on the rear. Allow time for heating/cooling. |
| Water has an unusual taste/odor | New unit residue; infrequent use; need for sanitization; water quality issue. | Flush several gallons of water through the system. Sanitize the unit. Consider a water filter if not already using one. |
| Unit is noisy or vibrating excessively | Unit not level; compressor vibration; internal component issue. | Ensure the unit is on a flat, level surface. Check for anything touching the back or sides of the unit. If noise persists, contact customer support. |
| Water leakage | Loose water line connection; damaged internal component; overflowing drip tray. | Check all water line connections for tightness. Empty and properly seat the drip tray. If leakage continues, unplug the unit and contact customer support immediately. |
| Burning smell from unit | New unit initial operation; dust on heating elements; electrical issue. | A slight burning smell can occur during the first few uses as manufacturing residues burn off. Ensure proper ventilation. If the smell is strong, persistent, or accompanied by smoke, unplug immediately and contact customer support. |
