4 PROCESS DESCRIPTION
This section provides general information regarding the heat disinfection
process utilized by the
Heatsan unit.
Operation
General philosophy of operation:
The unit can be configured to disinfect up to two distribution loops,
either individually or together. The user can set for each day of the
week which loop is to be disinfected and in what configuration.
The unit has been designed to provide up to 95 gallons of hot water for
the purposes of sanitizing connected dialysis equipment.
The number of machines that can be disinfected at any one time will
be dependent on the requirement of those machines regarding the
amount of water each machine needs for disinfection, the time taken
to perform heat disinfection and the flow at which they require the hot
water.
The system allows the user to input the specific requirements of the
dialysis machines to be disinfected, the days requiring heat disinfection
and the times which heat disinfection can occur.
If the system detects that any of the entered user values cannot be
achieved by the Heatsan unit the unit will raise an
“Invalid number”
alarm warning the user that the parameters loaded cannot be
achieved.
The typical stage duration times for disinfection can be found in
Section 6.10 Factory Default Settings.
Note: These values can be adjusted to fit requirements of your
particular distribution system. Verification of the efficacy of changes is
the responsibility of the medical director.
Preheat
The preheat stage is initiated prior to the Heatsan start time. The
start and return to service times being set by the clinical staff.
