Troubleshooting Guide - Guardian H920 Use & Care Instructions Manual

CLEANING
1. Always unplug the unit before servicing in any way.
GENERAL CLEANING
2. Inside the base of the unit. Pour excess water out of the unit. Wash out the unit with fresh water using the
cleaning brush and a soft cloth as needed. Do not submerse the base of the unit into water, or allow
water to enter inside the dry air exhaust port of the unit.
3. Water tank. Empty water tank. Remove mist nozzle and clean the mist tube with fresh water and a light
brush (bottle cleaning brush is recommended).
3. Outer surface of the unit. Wipe the surface of the unit with a soft, damp cloth if needed. If you notice an
accumulation of water during usage, reduce humidity and dry outer surface with a cloth.
DESCALING
• Depending on usage and water type, cleaning to remove scale may be required weekly or every
other week to optimize unit performance.
• If you live in a hard water area, we recommend the use of distilled water for your humidifier. This will
help reduce the precipitation of minerals or 'white dust'.
• Do not clean the unit or water tank with detergents or cleaning chemicals of any kind.
ULTRASONIC DISK
1. Unplug unit.
2. Remove the tank and empty all water from unit base and tank.
3. Locate the ultrasonic disk on the inside center of the base unit.
4. Use ONLY the enclosed cleaning brush to gently clean disk
and remove build up and deposits.
Do not scrub or scrape the ultrasonic disk.
If scale becomes difficult to remove with brush:
1. Fill the Base with: mixture of 1 tsp. white vinegar
and 1 tsp. water.
2. Let solution stand for 5 minutes.
3. With the vinegar in the Base, clean all interior surfaces
with a soft cloth or brush to help remove scale.
4. Also check mist nozzle and mist tube in water tank. Clean as needed.
5. Rinse the Base thoroughly with water to remove scale and vinegar solution.
END OF SEASON STORAGE
• Follow the Cleaning and Descaling instructions when the humidifier will be stored at the end of the season.
• Dry the humidifier completely before storing. DO NOT store with water inside the Base or Water Tank.
• Pack the unit in its original carton and store in a cool, dry location.
NOTE: IF YOU EXPERIENCE A PROBLEM DO NOT ATTEMPT TO OPEN THE MOTOR
