In the fast-paced modern life, hot, warm and cold water dispensers have become an indispensable appliance for many households and workplaces. To ensure the safety of water quality and the superior taste, regular replacement and maintenance of the filter cartridge have become particularly important. Today, we will introduce you to the steps for replacing the filter cartridge of the CW-919 gray model hot, warm and cold water dispenser, as well as the proper maintenance methods.

Step 1: Replacing the Filter Cartridge

The CW-919 hot, warm and cold water dispenser features an advanced 5-layer filtration system to ensure pure and safe drinking water. First, let’s understand the steps for replacing the filter cartridge:

  1. Open the casing of the water dispenser to expose the filter cartridge area.
  2. Remove the old filter cartridge layer by layer, following the instructions in the user manual. Replace the 4 layers of filter cartridges in sequence.
  3. Ensure that the new filter cartridge is correctly installed and secure each layer of the filter cartridge.

Step 2: Cleaning the Ceramic Filter Cartridge

The ceramic filter cartridge is an important component in the CW-919 water dispenser, responsible for removing tiny particles and impurities from the water to improve water quality. Regularly cleaning the ceramic filter cartridge can extend its lifespan and effectiveness. Here’s how to clean the ceramic filter cartridge:

  1. Remove the ceramic filter cartridge and rinse it gently with running water to remove any accumulated dirt.
  2. If the dirt is stubborn, you can use a soft-bristle brush to gently scrub, but avoid using a brush that is too abrasive to prevent damaging the surface of the filter cartridge.
  3. After rinsing thoroughly, allow the ceramic filter cartridge to air dry, and then reinstall it into the water dispenser.

Step 3: Cleaning the Water Storage Tank

The water storage tank is where the water is stored in the water dispenser, so regular cleaning can prevent the growth of bacteria and maintain the freshness of the water. Here’s how to clean the water storage tank:

  1. Empty the remaining water and thoroughly clean the interior and exterior surfaces of the water storage tank with mild soapy water.
  2. Rinse with clean water to ensure that all soap residue is completely removed.

By regularly replacing the filter cartridge, cleaning the ceramic filter cartridge, and cleaning the water storage tank, you can ensure that the CW-919 hot, warm and cold water dispenser continues to provide fresh and pure drinking water. These simple steps not only protect the health of you and your family but also extend the lifespan of the appliance. Remember to follow the recommendations in the user manual to ensure proper operation and safe maintenance.
