HUMIDIFIER SAFETY 

PLEASE READ AND SAVE
THESE IMPORTANT 
SAFEGUARDS

When using electrical appliances, basic safety precautions
should always be followed to reduce the risk of fire, electric
shock, and injury to persons, including the following:
1. Read all instructions before using the appliance.
2. To avoid fire or shock hazard, plug the appliance 

directly into a 120V AC electrical outlet.

3. Keep the cord out of heavy traffic areas. To avoid fire

hazard, NEVER put the cord under rugs or near heat
registers.

4. DO NOT place humidifier near heat sources such as

stoves, radiators, and heaters. DO locate your
humidifier on an inside wall near an electrical outlet. The
humidifier should be at least 4 inches (10 cm) away
from the wall for best results.

5. NEVER place humidifier in an area where it is accessible

to children. NEVER use humidifier in a closed room,
particularly where a child may be sleeping, resting, or
playing (a closed room may result in excessive humidity).

CORD AND PLUG INSTALLATION SAFETY
INSTRUCTIONS

This appliance has a POLARIZED AC

plug. If it still does not fit, contact a

qualified electrician to install the proper outlet. 

DO NOT ATTEMPT TO MODIFY THIS PLUG OR
DEFEAT THIS SAFETY FEATURE IN ANY WAY.

The length of cord used on this appliance was selected to
reduce the hazards of becoming tangled in, or tripping
over a longer cord. If a longer cord is necessary an
approved extension cord may be used. The electrical
rating of the extension cord must be equal to or greater
than the rating of the humidifier (refer to the rating label
placed on the humidifier). Care must be taken to arrange
the extension cord so that it will not drape over the
countertop or tabletop where it can be pulled on by
children or accidentally tripped over.

FREQUENTLY ASKED QUESTIONS

QUESTIONS

ANSWER

• What are the 

variables that
affect run time?

The estimated run time for this
humidifier is based on average room
conditions. The actual run time of your
humidifier is dependent on numerous
variables such as:
1. Air exchange in the room where 

the humidifier is placed.

2. Room construction where the 

humidifier is placed.

3. Temperature of the room where 

the humidifier is placed.

4. Humidity levels in the room where 

the humidifier is placed.

Regular cleaning is recommended.

• How can I

extend the
run time?

1. Run your unit on the lowest setting.

(not applicable to BU5210)

2. Fill the tank all the way full, place it 

on the base, let the water empty 
into the base until it stops bubbling,
then refill the tank full again. This 
ensures maximum water capacity 
and will extend run time.
