IMPORTANT SAFETY
INSTRUCTIONS

READ AND SAVE THESE
SAFETY INSTRUCTIONS
BEFORE USING THIS AIR
PURIFIER

When using electrical appliances, basic
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 operating the air

purifier.

2. Place air purifier where it is not easily knocked

over by persons in the household.

3. Always turn the air purifier controls to the OFF

position and unplug from the wall outlet when
not in use.

4. To disconnect the air purifier, press the Power

button ( ) to turn the unit off, grip the plug
and pull it from the wall outlet. Never pull by
the cord.

5. Do not use any product with a damaged cord

or plug or if product malfunctions, is dropped
or damaged in any manner. Keep the cord
away from heated surfaces.

6. Do not use air purifier outdoors.

7. Never use air purifier unless it is fully

assembled.

8. Do not run power cord under carpets, and do

not cover with throw rugs. Arrange cord such
that it will not be tripped over.

9. Do not use air cleaner where combustible

gases, vapors or an oxygen rich environment
are present.

10. Do not expose the air purifier to rain, or use

near water, in a bathroom, laundry area or
other damp location.

11. The air purifier must be used in its upright

position.

12. Do not allow foreign objects to enter ventilation

or exhaust opening as this may cause electric
shock or damage to the air purifier. Do not
block air outlets or intakes.

13. Locate air purifier near the outlet and avoid

using an extension cord.

14. This appliance has a polarized plug (one blade

is wider than the other). To reduce the risk of
shock, this plug is intended to fit only one way
in a polarized outlet. If the plug does not fit
fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician.

DO NOT attempt to defeat this safety feature.

15. A loose fit between the AC outlet (receptacle)

and plug may cause overheating and a
distortion of the plug. Contact a qualified
electrician to replace loose or worn outlet.

16. Do not sit, stand or place heavy objects on the

air purifier.

17. Disconnect power supply before servicing.

WARNING: To Reduce The Risk of Fire or
Electric Shock, Do Not Use This Air Purifier
With Any Solid-State Speed Control Device.

The sealed UV bulbs contain a small
amount of mercury. Dispose of these items
at household hazardous waste collection
sites only. If the UV bulb breaks, do not
vacuum or handle with your bare hands.

INSTALL HEPA-TYPE FILTERS

The HEPA-Type Filters are supplied within the air purifier. They are wrapped to ensure purity.

• Make sure the air purifier is turn off and unplugged.

• Remove the rear grille by pressing the notch on the top of the rear grille and
pulling the grille towards you (Fig. 2).

• Remove the filters by gently pushing along the edge of the filter frame and
pulling it forward. Repeat for the second filter.

• Remove the protective wrap from the filters.

• Place the filters back into the air purifier housing and snap the rear grille back
into place.

Note that the pre-filter needs to be in position along the rear grille before snapping
the grille back into place.

The Top filter must be in place in order for the unit to operate.

Fig. 2

SET-UP

• Select a firm, level and flat location. For proper airflow, locate the unit at least 3 feet (1 M) from any
wall or furniture.

• When operating, large volumes of air are drawn toward the air purifier. Surrounding areas should be
cleaned and/or vacuumed frequently to prevent build-up of dust and other contaminates. This may also
help prolong the life of the filter. If the unit is placed on a light colored carpet, a small mat or rug should
be used underneath to prevent permanent staining. This is especially important in homes with
contamination from smoking, fireplaces or where candles are burned.

• Ensure the exit grille (front of the unit) faces away from the closest wall or furniture.

• Ensure no grilles are blocked.

Fig. 6

Fig. 7

This model is equipped with permanent HEPA-Type filters which never need
replacement with normal use.

To Clean Your HEPA-Type Filter:

• DO NOT USE WATER OR OTHER LIQUIDS TO CLEAN THE HEPA-TYPE FILTER.

• It is recommended that you use a vacuum cleaner that has a HEPA filter built
into it. If a HEPA filter vacuum is not available, you should vacuum your HEPA
filter outdoors to keep the particles from getting recirculated in the air in your
home.

• To vacuum-clean the filter, hold the filter and run a vacuum cleaner with a
nozzle or brush attachment along the filter to pick-up the dirt and particles (Fig. 8). Repeat along the
entire surface of the HEPA-Type filter. We recommend that a vacuum with hepa filtration is used for
cleaning the filters.

• Note the filter may still be discolored even after cleaning it. This is acceptable and will not affect
performance.

• After vacuuming the filter, place it back into the air purifier housing and snap filter grille into place.

These cleaning intervals are intended as guidelines only.Performance of any filter media is dependent upon
the concentration of contaminates going through the system. High concentrations of contaminates
such as dust, pet dander and smoking will reduce the useful performance of the filter.

NOTE: The HEPA-Type filters are not washable.

CLEANING THE HEPA-TYPE FILTERS

Fig. 8

HHT-145_OM.qxd 11/21/06 5:42 PM Page 5

The stage 1 particle pre-filter helps pick up large airborne
particles that enter the rear grille. This pre-filter can be
periodically removed and shaken to clean it. Alternatively,
it can be rinsed by hand under warm water (Fig. 9). Let
the pre-filter air dry completely before inserting back into
the unit (Fig. 10). If you need to replace this item, please
call 1-800-477-0457 or visit www.kaz.com.

OPTIONAL: Changing the Odor Control Filter

If you have chosen to use the CZ odor control filter that came with your air
purifier, it will lose its effectiveness over time and will need to be replaced.
Call 1-800-477-0457 or visit www.kaz.com to order your replacement odor
control filters.

If using the CZ odor control filter, it is recommended that you store the original
washable pre-filter in the event that you decided to use it in the future.

To insert it into the unit, simply place securely into the rear grille in lieu of
standard pre-filter as shown in figure 10.

Note: The CZ filter is not washable.

We recommend that you clean the air purifier at least once every 3 months and before extended storage.
Use only a dry cloth to wipe the external surfaces of the air purifier. DO NOT USE WATER, WAX POLISH,

OR ANY CHEMICAL SOLUTION.

If your Air Purifier will not be used for more than 30 days, we recommend:

• Remove the HEPA-Type Filters from the unit.

• Wrap the HEPA-Type Filters in an air tight plastic bag and store with the unit.

CLEANING AND STORAGE

My filter bar says my filter is still relatively clean but when I checked my filter, it was really dirty

In conditions where smoke, pets or air with a lot of contaminants are present it is possible that the filter
could be dirty sooner than indicated on the indicator.The filter life indicator on your unit runs on a timer
and if there are more particles in your air than in an average home, your filter could capture airborne
particles sooner than indicated on the display.The indicator is intended to be used as a guideline and
individual environmental conditions will vary.

My unit will not turn on.

The air purifier has safety features to ensure that the unit is ready for operation. Check to make sure
both HEPA-type filters are installed flush to the air purifier. Check to make sure the rear cover is
installed flush with the unit and is locked.

When do the UV bulbs need to be replaced?

The “Replace UV Bulb” message and light will turn on after 6 months of continuous use, so the bulbs
should be replaced at this time.

My Air Purifier is starting to make noise and the air output is less. What’s wrong?

The filters may be dirty. High amounts of contaminates can block the pores in the filter and stop the air
from moving through it. Clean the Filters.

How long should I run my Air Purifier?

For best results, you should operate your Air Purifier 24 hours a day.This unit will be more effective
when doors and windows are closed.

Can I wash my HEPA-Type filter?

No. Washing the HEPA-Type filter will destroy it.

How does the electronic filter check work?

The filter check LED will light up after 3 months of continuous operation of the air purifier.

How does the UV check light work?

The UV check light will change from green to red when it is time to change the UV bulbs. Follow the
instructions located in “Replacing the ultraviolet (UV) bulbs”.
