Water Lines
Disinfect the water lines weekly. Prepare a 1:10 bleach
solution (1 part household bleach to 9 parts water).
Remove water supply bottle and discard residual water.
Replace the empty water supply bottle and air purge all
waterlines. Fill water supply bottle with bleach solution.
Run bleach solution through all lines. Allow bleach solution
to stand in lines for 10 minutes. Remove water supply
bottle and discard bleach. Flush water supply bottle and all
lines thoroughly with clean water. Air purge and leave lines
dry until next clinical use.

Adhesives
Refer to included Schematic Drawing Set, PN 420991, for
proper identification and application of all adhesives.
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.
CAUTION:
Do not run saline solutions through the water
system -- saline will rust the water filters.
