perform the following before rinsing with glycerin:
• Charcoal Filter (if equipped)
1. Remove the charcoal filter bowl.
2. Remove the water from the bowl.
3. Replace the charcoal filter element with a new charcoal filter element.
4. Replace the bowl back onto the lid.
• pH Neutralizing Filter (if equipped)

• UV Sterilizer (if equipped)
Disconnect the product water line from the UV sterilizer
filter and drain product water from it.
After rinsing with glycerin, switch the power to the system OFF. Lock and
