Warning

If the Chemi-Filter cartridge is broken,

avoid contact with skin and eyes and

avoid breathing dust. For additional

information, see the Material Safety

Data Sheet.

Do not attempt to remove the cartridge

while the sterilizer is processing.
Replace only with a Harvey Chemi-

Filter.
To dispose of the used cartridge

consult the Material Safety Data Sheet.
Frequently check the Chemi-Filter for

expiration. Replace per filter chart as

required.

Figure 33: Replacing the Chemi-Filter

When Required

Replacing the Chemi-Filter

Be sure the power switch is OFF (see Figure

33).

Grasp the pull strap at the top of the used

Chemi-Filter. Remove the filter from the filter.

Remove the new Chemi-Filter from its package.

Mark the replacement date in the “Replace By”

box on the Chemi-Filter label. To calculate the

date , read the chemi-filter label or refer to

“Finding the Replacement Date” (following).

Grasp the pull strap at the top of the Chemi-

Filter. Insert the filter opening. Push the filter

down as far as possible.

Dispose of used Chemi-Filter according to local,

state and federal regulations.

Finding the Replacement Date

•

Calculate the replacement date by adding the

number of months until replacement to the

current month.

•

Use the chart on the Chemi-Filter label to find

the number of months until replacement.

•

The chart on the Chemi-Filter label is based on a

5-day workweek and an average number of

cycles/workday of 2, 4, 6, 8, 10 or 12.

•

If your usage differs from these values, calculate

the months of replacement as shown in “Months

Until Replacement Calculation.”
