pipeline system. Failure to clean and disinfect the wall outlet and pipeline system may result in damage to this equipment. w WARNING: Perform the service checkout procedure (Section 8 Service Checkout

Procedure) following cold flushing. Validate the selected cleaning/disinfection procedure.

Failure to do so may result in patient use of a product which is assumed to be clean/ disinfected and is not. Body fluids suctioned into a vacuum regulator do not stop in the regulator. They proceed through it into the wall outlet and pipeline system. Failure to clean and disinfect the wall outlet and pipeline system may result in contamination that contributes to nosocomial infection.

5.2 Sterilization

Should misuse occur, resulting in accidental flooding of the regulator, the regulator may be sterilized using ethylene oxide (ETO). After sterilization, follow the service checkout procedures in Section 8.

w WARNING: Following sterilization with ethylene oxide, parts should be quarantined in a well ventilated area to allow dissipation of residual ethylene oxide gas absorbed by the material. Aerate parts for 8 hours at 130

(54 o procedure.

o F

C). Follow your hospital sterilization w CAUTION: Do not steam autoclave or liquid sterilize the ISU. Severe impairment to the operation of the regulator will result. The only acceptable method of sterilization is with gas

(ethylene oxide).

w CAUTION: Sterilization with ethylene oxide mixtures may cause crazing (minute superficial cracking) of some plastic parts. Crazing will be more pronounced when mixtures containing

Freon ® are used.

Note: ISU should only be sterilized if it is contaminated or maintenance is to be performed.

1. The regulator should be sterilized with the mode selector knob in the |O|O| (INTER) position.

2. The only acceptable method of sterilization is with ethylene oxide. Ethylene oxide mixtures can be used at temperatures of 125 to 135°F (52-57°C).

If this temperature cannot be obtained, room temperature sterilization with 100% ethylene oxide can also be used. Sterilization is not recommended as a standard procedure after each use.

3. After each sterilization check the condition of the internal filters. Replace any shrunken filters before returning the regulator to service.

Place the regulator in the vertical position and connect to a supply vacuum of 500 mmHg (66.7 kPa).
