Key Takeaways

Cleaning Your Vertical Water Dispenser

How Often to Clean

How often should you clean your vertical water dispenser? For most commercial spaces, a good rule is to sanitize the inside every three to four months. If your area sees heavy use, stick to the three-month mark. Regular cleaning keeps bacteria and mold away, so your water always tastes fresh. Don’t forget to wipe down the exterior and clean the drip tray every week. If your Mejec dispenser has smart monitoring, you’ll get handy alerts when it’s time for maintenance or filter changes.

Tip: Always follow the manufacturer’s instructions for filter care and cleaning schedules.

Safety Tips for Cleaning

Safety comes first! Always unplug the dispenser before you start. Drain all water from the reservoir. Let hot surfaces cool down. Use only approved cleaning solutions and never spray liquids directly into electrical parts. Keep all openings closed while cleaning. Never immerse the dispenser in water.

Note: Smart monitoring on Mejec models helps you stay on top of cleaning and maintenance, so you never miss a step.

Step-by-Step Cleaning and Maintenance

Preparing the Dispenser

Before you start the cleaning process, make sure you prepare your vertical water dispenser the right way. Here are the steps you should follow:

  1. Unplug the water dispenser from the wall. Safety comes first, so always cut off the power.

  2. Remove the water bottle if your model uses one. Set it aside in a clean area.

  3. Move any nearby electrical devices away from the dispenser. This helps prevent accidents if water spills.

  4. Let any hot surfaces cool down before you touch them.

Taking these steps helps you avoid electric shock and keeps your cleaning routine safe and smooth.

Cleaning the Exterior and Drip Tray

The outside of your vertical water dispenser can collect dust, fingerprints, and even germs. The drip tray is a hotspot for spills and bacteria, so regular cleaning is key. Here’s how to tackle these areas:

  • Remove the drip tray and any removable grids or baffles.

  • Wash the drip tray with mild soap and warm water. Use a soft cloth or sponge to scrub all surfaces, including the underside of the grid.

  • Rinse the tray and parts with clean water to remove any soap.

  • Dry everything thoroughly before putting it back.

  • Wipe down the exterior of the dispenser with a damp cloth and a little dish soap. Pay attention to buttons and handles.

  • For high-traffic areas, give the drip tray a quick wipe every day and a deep clean every week.

Tip: Let all parts air dry completely before reassembling. This helps prevent mold and keeps your water dispenser fresh.

Cleaning and Sanitizing the Reservoir

The reservoir is where water sits before you drink it, so keeping it clean is essential for hygiene and the disinfection of potable water. To clean and disinfect your water cooler, follow these cleaning instructions:

  • Mix a cleaning solution using either two tablespoons of bleach or two cups of vinegar with a gallon of water. Vinegar is a great natural option for sanitization and removing contaminants.

  • Pour the solution into the reservoir.

  • Let it sit for about 10-15 minutes. This process helps disinfect and break down any buildup.

  • Use a non-abrasive brush or sponge to scrub the inside surfaces gently.

  • Drain the solution completely from the dispenser.

This cleaning process removes bacteria and keeps your water tasting great. Remember, the importance of proper cleaning cannot be overstated—clean water dispenser means healthier water for everyone.

Flushing and Reassembling

After sanitizing, you need to flush out any leftover cleaning agents. Here are the steps:

  1. Fill the reservoir with clean water.

  2. Drain all the water through the taps to rinse out any vinegar or bleach.

  3. Repeat this process two or three times to make sure no cleaning solution remains.

  4. Wipe down the taps and any other parts that come in contact with water.

  5. Reassemble the drip tray and any other removable parts.

If you use any special cleaning chemicals, make sure to neutralize them with a passifying agent or a neutralizing rinse. This step is important for the disinfection process and ensures your water is safe to drink.
