- Power Connection: Plug the power cord into a grounded electrical outlet. The unit will power on and initiate a self-check.
- Initial Flush: Before first use, perform an initial flush to clean the system. Place a large container under the dispenser. Press the "Flushing" button (or equivalent on your model's interface) and allow the system to dispense water until the tank is empty. Repeat this process 2-3 times to ensure thorough flushing and optimal water quality.
Operating Instructions
- Filling the Tank: Ensure the raw water tank is filled with tap water. The system will indicate when the water level is low.
- Dispensing Water: Place a cup or container under the dispenser nozzle. Select the desired water volume (e.g., 6 oz, 12 oz, 15 oz) by pressing the corresponding button on the control panel. The system will automatically dispense the selected amount of purified water.

Maintenance
Filter Replacement
The SimPure Y7P-BW uses two main filters: a Composite Filter (CF) and a Reverse Osmosis (RO) Filter. Both filters have an estimated service life of 6 months or 528 gallons, whichever comes first. The system will indicate when filters need replacement.

- Power Off: Unplug the unit from the power outlet.
- Remove Filters: Open the filter compartment cover. Twist the old filters counter-clockwise to unlock and pull them out.
- Install New Filters: Insert the new filters into their respective slots (CF and RO). Twist clockwise to lock them into place. Ensure they are securely seated.
- Reset Filter Life: After replacing filters, plug the unit back in. Press and hold the filter reset button (refer to your control panel diagram) for a few seconds until the filter indicator light resets.
- Flush System: Perform a flush cycle (as described in "Setup") after replacing filters to ensure proper function and remove any air bubbles or carbon fines.
Cleaning the Water Tank
Regular cleaning of the raw water tank is recommended to prevent mineral buildup and maintain water quality. Clean the tank at least once a month or as needed.
- Remove the raw water tank from the unit.
- Empty any remaining water.
- Wash the tank with mild soap and warm water. Rinse thoroughly to remove all soap residue.
- Dry the tank completely before reinserting it into the unit.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| "Change Water" Indicator On | Raw water tank is empty or water quality is low. | Refill the raw water tank with fresh tap water. If the light persists after refilling, ensure the tank is properly seated. |
| Slow Water Dispense | Clogged filters or air in the system. | Check filter status and replace if necessary. Perform a flush cycle to remove air. |
| Water Tastes Unusual | New filters not flushed, or filters need replacement. | Perform additional flush cycles. Replace filters if they are past their service life. |
| Unit Not Powering On | Power cord not connected, or power outlet issue. | Ensure the power cord is securely plugged into a working outlet. Try a different outlet. |
