CLEANING & MAINTENANCE
Cleaning External Surfaces
1. Turn off and unplug unit.
2. Use a washcloth slightly dampened with
a little water and dishwashing soap
to wipe the outer case surfaces.
3. Do not allow water to slip into the internal parts
as this could damage your unit and result in
electrical shock and injury to you.
4. Allow the unit to thoroughly dry before use.
UV Lamp
The lifetime of the UV lamp is up to 12 months of
continuous, effective operation. After this time, the
bulb may remain illuminated, but its effectiveness
is greatly reduced.
For maximum germicidal
protection, please replace the UV bulb annually.
If the lamp stops functioning or needs
replacement, please visit our web site at
www.envionproducts.com to order a
replacement lamp. Or call 1.800.875.8577.
Caution:
•
Do not touch the glass part of the lamp. Oil
from fingertips will decrease the effectiveness
of the lamp.
•
Never operate the unit without a filter or with
a damaged filter. UV lamp cover must be
installed at all times. The UV light from the UV
lamp will result in severe damage to eyes and
could cause blindness.
UV Lamp Notice Warning:
UV Light is harmful to bare skin and eyes and can
cause temporary or permanent loss of vision.
Never look directly at the UV lamp while it is
illuminated-doing so could cause loss of vision!
Before replacing the UV lamp, make sure the Therapure
®
540 air purifier is turned
off and unplugged. Let the lamp cool down for 5 minutes before replacing it.
Replacing the UV Lamp:
1. Release the inlet grill by pressing on the locking latch.
2. Grasp the left and right frames of the permanent HEPA-type Filter through the
indentations on the sides of the filter enclosure and remove filter.

the unit then unscrew the old UV lamp from the lamp base of the unit.
