ROUTINE MAINTENANCE:

WATER LINES – Disinfect the water lines weekly. Prepare a 1:10 bleach solution (1 part household bleach to 10 parts water). Remove water reservoir and discard residual water. Replace empty water supply tank and air purge all waterlines. Fill water supply tank with bleach solution. Run bleach solution through all lines. Allow bleach solution to stand in lines for 10 minutes. Remove water supply tank and discard bleach. Flush water supply tank and all lines thoroughly with clean water. Air purge and leave lines dry until next clinical use.

ESD PRECAUTIONS

The following electrostatic controls must be used when working on this unit:

• ESD Training and Standards:
  Employees handling electronic sub-assemblies and ESD-sensitive components are expected to be trained. Training should be based on IPC-A-610 or equivalent ESD standard ANSI/ESD-S-20-20 – Protection of Electrical and Electronic Parts, Assemblies and Equipment.

• ESD Static Controlled Area:
  Areas that are designated for handling and working on electronic sub- assemblies or their components should be marked off with signs indicating the area where ESD controls are to be enforced. These areas are to be kept clear from persons that are not trained to prevent ESD damage from occurring.

• ESD Environment:
  The work area is to be free of all static generating materials, such as plastic containers, water bottles, plastic bags, plastic objects, such as plastic pens, heat guns
  (unless made for the ESD environment).

• ESD Jackets:
  Clothing should be non-static generating (cotton).
  Static generating clothing (e.g. wool, acrylic, nylon) must be covered with an ESD jacket that is buttoned closed.

• Optional gloves:
  Nitrile gloves may be used to cover the hands when working, but are not required.

• Seating:
  ESD Chairs should be used in place of static generating chairs (e.g. modern office seating use static generating materials).

• Storage and packaging:
  All circuit boards and components are to be stored on or in static dissipative or static shielding material, throughout shipping and storage.

• ESD Wrist Strap and Mat Routine Checks:
  The wrist strap should be checked daily using an ESD wrist strap testing station. See chart below.
  ESD mats should be checked at least quarterly.

BASIC DISASSEMBLY

1. Make sure the unit is turned off and unplugged from all AC and DC power sources.
2. Make sure all accessories have been removed from the unit.
3. Stand the unit upright, into its operating position. Remove the water bottle. Go to the rear of the case and remove the two upper screws with a #2 Phillips head screwdriver. Go to the top of the unit and remove the two screws while supporting the chassis with your hand. Remove the chassis from the case (Fig. 1).
