Section 5 Routine Maintenance
Warning If the unit has been in service, turn it off and disconnect the
power cord connector before proceeding with any maintenance. s
Caution Before using any cleaning or decontamination method except
those recommended by the manufacturer, users must check with the
manufacturer that the proposed method will not damage the equipment.
s
Use an appropriate disinfectant. All articles and surfaces to be disinfected
must be thoroughly cleaned, rinsed with sterile water, and rough dried.
Warning Alcohol, even a 70% solution, is volatile and flammable. Use it
only in a well ventilated area that is free from open flame. If any
component is cleaned with alcohol, do not expose the component to open
flame or other possible hazard.
Do not spray T/C sensor with flammable solutions. The internal
temperature of the CO
2 sensor is approximately 150°C when the unit is in
operation. Allow sufficient time for the sensor to cool before cleaning.
s
Caution Do not use strong alkaline or caustic agents. Stainless steel is
corrosion resistant, not corrosion-proof. Do not use solutions of sodium
hypochlorite (bleach) as they may also cause pitting and rusting. s
1. Remove the shelves, HEPA filter (a factory installed option), access
port filter, sample air filter, left and right duct sheets and the top duct.
The top duct requires the two wing nuts to be removed.
2. Set the HEPA filter aside. Wash the shelves, ducts, wing nuts and
stopper with disinfectant. Optional: The shelves, ducts and wing nuts
may be autoclaved.
3. Remove the blower scroll held on by four screws. Remove the blower
wheel and the access port filter. If a new blower wheel and scroll are
going to be used, discard the old ones. If the old ones are being
reused, wash and rinse all parts with disinfectant.
