Months Until Replacement Calculation
Values Needed:
1. Assign proper values to c, D and T.
c = no. of cycles/workday (operator defined)
D = no. of workdays/week (operator defined)
T = Total no. of cycles before filter needs
replacement (see chart below).
Total Cycles Before Replacement (T)
Model
EC5500 EC6000
Total Cycles (T) 500 250
Calculation:
2. Insert the values for c, D and T into the
formula:
no. of months until replacement = 0.231 x (T/[c
x D])
Example:
A. An operator has an EC5500 sterilizer. She
intends to run it 7 cycles each day, 4 days/
week.
How soon must she replace the Chemi-Filter?
Solution:
c = 7, D = 4 and T = 500. Substituting into the
formula, we get:
0.230 x (500/[7 x 4]) = 4.125
Replace the Chemi-Filter after 4 months.
Replacing the Door Gasket
Replace the door gasket at least once a year.
1. Open the door. Use a blunt instrument to lift it
from the gasket groove.
2. Remove the gasket from the gasket groove in
the rim of the chamber.
3. Clean the gasket groove and sealing surface
so that it is free of dirt or of deposits.
