Page 66: Maintenance
• The humidifier frequently drains the water completely to dilute it and perform a complete wash; Zephyr OEM series humidifiers normally renew the water in the boiler in a balanced way, optimising efficiency while reducing the risk of malfunction in relation to the amount of steam produced. -
Page 67: Checking The Status Of The Humidifier
• In the event of water leakage, disconnect the humidifier power supply immediately. • If any adverse event not described in this documentation arises, carry out maintenance and/or replace the boiler. Plus, contact ELSTEAM customer service for the relevant guidelines and instructions; DANGER RISK OF ELECTRIC SHOCK, EXPLOSION OR ELECTRIC ARC If an adverse event occurs, disconnect the humidifier power supply immediately. -
