4PROCESS 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 6.9 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.
(Tank) 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. Water is taken off the loop during the preheat stage.
During this stage the unit fills the tank with only the amount of permeate needed for the
number of machines programmed in by the operator. This feature saves on power and
water consumption.
The heaters then raise the temperature to the tank preheat temperature and hold it until
the timed Heatsan start period is reached. The pre-heat stage reduces the risk of thermal
shock to pipework and reduces the time taken to achieve disinfection temperature.
Loop Preheat (Heatsan Operation)
CAUTION: Once the Heatsan Start time is reached, hot water will be directed into the loop.
Ensure that no patients will be online when the “Heatsan Start” time is reached.

12 98-0156, Rev J
Once the pre-programmed “Heatsan Start” time has been reached the Heatsan will isolate
the RO from the distribution loop. The Heatsan will then be automatically connected to the
loop using the motorized valves on the associated manifold. The internal pump will circulate
the preheated water around the distribution loop(s) to be disinfected. The system will
continue to heat the water until the pre-set disinfection temperature is achieved. The
circulation period is set by the loop pre-heat value on the HMI, the factory default can be
found in Section 6.9.
Hold Period (Heatsan Operation)
After the “loop pre-heat” stage has timed out, the system is then held at the disinfection
temperature for the hold time. The default hold time can be found in Section 6.9. The
temperature is maintained by switching on 1, 2, or 3 heaters, depending on the selection of
loop size in Section 6.6 Factory set-up.
Draw Off Period
The default time for this stage can be found in Section 6.9. The minimum time is adjustable.
The maximum time is calculated from the times pre-programmed in by the user relating to
the stop/start times and the duration for the heat disinfection cycle on the connected
dialysis machines.
Cool Down Period
Once the water availability stage has timed out the system will proceed into automatic “Cool
down”. The system will perform a series of tank drain downs and introduce cold RO
permeate into the distribution loops until the return temperature on the system falls below
the “maximum service temperature” setting. The factory default for this can be found in
Section 6.9. On reaching this temperature the system automatically disconnects itself from
the loop(s) and re-introduces the RO unit(s).
Drain in Operation
Following the Cool down period, the tank drain valve will remain open until the tank level
falls to zero at which point the unit will return to STANDBY. To ensure that the tank remains
empty during STANDBY the drain valve will open for 5 minutes every 2 hours.
Standby
STANDBY will be displayed to indicate that the unit is “healthy” and waiting for the next
heat disinfection routine to initiate.

hydraulic connections. Inspect for any damage. Ensure that the installation kit has been
provided with the unit.
Electrical Supply
WARNING: An electrical supply (see specification Section 3.5) should be made to the control
panel of the Heatsan 400 unit using suitably sized 3-phase cable based upon the maximum
current draw of the unit while considering the length of the cable between the disconnect
and the Heatsan 400 unit by an authorized electrician. Please follow local electrical code (for
example NEC or CEC) for mains wiring connections using a 40 A maximum service for
00HS20809 or a 60 A maximum service for 00HS20815. The cable should be fitted using
appropriately sized gland and terminated to the isolator connections L1, L2, L3 and Earth.
Water Connections
Refer to Section 10.4.
Drain
A suitable, unrestricted, drain is required, capable of handling the discharge flow of the
Heatsan unit (see specification). The drain should be capable of accepting 203°F water.
Overflow
An unrestricted overflow must be provided which terminates with an air gap that conforms
to any local or National regulations. The overflow pipework must be capable of withstanding
water up to 203°F. Overflow and drain MUST be independently run to drain.
Hot Water Flow/Return
The flow and return connections should be connected directly to the distribution loop via a
manifold assembly with valves.
