Product Information

The Thermo Scientific TII is a tap-fed water purification system designed to be simple to use and to
provide reagent-grade water that exceeds ASTM Type II, and CLSI®-CLRW standards. It uses a thin
film composite reverse osmosis membrane with pretreatment to produce RO water that is then
polished using a two-stage deionization process combined with UV oxidation and a 0.2 micron final
filter.

The % of the rejection between incoming and reverse osmosis product water is monitored and an
indication is provided to the user if the RO water quality is unacceptable. Pressure sensors located
inside the unit monitor incoming feed water and RO pressure. The DI water purity is continuously
measured by a resistivity cell and displayed on a multifunctional display.

RO operation is automatic and works independently of the DI system to fill the external reservoir as
determined by sensors in the reservoir.

Read the instructions carefully to ensure that you receive maximum benefit from the Thermo Scientific
TII. Also, please fill out and return the enclosed warranty registration card, as it will help us assure you
of proper warranty coverage.

System Cleaning Procedure

Figure 3-21 Typical TII Display

Prior to beginning the cleaning procedure, ensure the Thermo Scientific TII is attached to a suitable
reservoir and that all water and electrical connections between the Thermo Scientific TII and the
reservoir are in place. The system should be cleaned before the first use, before a new cartridge pack is
installed, or whenever the one-year cleaning timer alerts you. Once set up, the cleaning procedure will
run automatically. It is best to perform the procedure when the system or water will not be required as
the entire procedure can take up to 16 hours to complete. A cleaning block (BK1403X2) should
already be installed, see

Cleaning Preparation in this section for details. You will also need a quantity of

household bleach per the chart on following page.

Do not use bleach with added fragrances. Cleaning your Thermo Scientific TII system as follows:

Note An alternative reservoir must have at least two ports to connect it to the TII to allow

for recirculation.

Note TII system must be programmed to work with the alternate tank configuration.

Refer to

Reservoir Connection in the “System Options” section of this manual to correctly

configure the TII system.

Note Test the float switch assembly in the reservoir to make sure the water level registers

on the display before you begin the sanitization mode. You can do this by gently moving
the float switches in the tank and looking to the reservoir display to see if it registers. See
Figure 3-20 to help locate the reservoir display. This figure shows that the reservoir is 75%
full.

1. Verify Cleaning Preparation section has been completed to prepare your system for cleaning.

2. Press the “Menu” key, and use the up and down arrow keys to select “Sanitization”.

3. Follow the prompts on the screen. These will guide you through the process. It is very important
that the steps are followed in order for the cleaning to be successful. Be sure to connect the
tubing supplied with the cleaning block and route securely to an atmospheric drain to prevent
spillage as the system will use this tubing to automatically drain the bleach water from the
system. It is also important that any equipment connected to the optional distribution loop be
disconnected from the loop and the lines plugged to prevent bleach from entering those systems
or leaking from the distribution loop.

4. When prompted to add bleach, add per the following chart:

Once the bleach has been added, if the cleaning cycle is cancelled the system will not be available
until it thoroughly rinses all of the bleach from the reservoir and tubing. This will take up to 8 hours.

To complete the cleaning, the system will automatically fill the reservoir and recirculate the bleach
solution through the reservoir and system for six hours. It will then completely drain the solution
from the reservoir and tubing by dispensing it through the system dispenser. The reservoir will then
be automatically refilled and water which will be re-circulated through the system and again
dispensed out the system dispenser to rinse out all remaining bleach.

Once the cleaning is complete, the screen will prompt you to install a new cartridge pack (see

Cartridge Pack Installation section of this manual), and will then begin filling the reservoir for

normal use. Never install a used cartridge pack into a cleaned system to avoid re-introducing bacteria.

Optional accessories for this unit include a standard remote dispenser, Accudispense volumetric
remote dispenser, dispense overflow cutoff float and printer. For ordering information, refer to
Ordering Information - TII Accessories. If you purchased a standard or Accudispense volumetric
remote dispenser, refer to their respective operator’s manuals for installation instructions.

Dispense Overflow Cutoff Float

The dispense overflow cutoff float (AY1367X1) ships with a 6 ft. [1.83 meter] cable and is designed
as a user option to ensure automatic dispensers (time or volumetric) do not overflow carboy style
containers. This accessory can be especially helpful if the actual volume of a container is unknown. It
can also protect against overflows if the entered/stored volume of a previous container has not been
changed and is set for a volume greater than the carboy being filled. Finally, the accessory can be
useful for automatic time dispenses as it is usually difficult to ensure the set time will equal a specific
volume of water. If the auto dispense is stopped by the overflow float, the Thermo Scientific TII will
change modes to normal recirculation.

1. Prior to initiating an automatic dispense (timed or volumetric), plug AY1367X1 into connector
on the back left side of the Thermo Scientific TII as shown in Figure 3-27.

2. Position carboy to be filled and place float assembly on open neck of carboy. Position float
assembly such that it will not interfere with product water stream being dispensed into carboy.

3. Initiate Auto Dispense as described in the “Automatic Dispensing” section of this manual. If,
during the auto dispense, the float is lifted by the rising water, the auto dispense will immediately
be stopped and an error message will be displayed momentarily.

Thermo Scientific TII’s pump will begin to run and display the purity of the product water if the
water level is above 25%.

2. Allow the water’s purity to rise to the desired level before dispensing water. Also, in the RUN
mode, the RO operation automatically turns on to fill the reservoir as needed. When the reservoir
is full, the RO system will automatically return to STANDBY.

a) DI system in Run and RO system in Standby,
b) RO and DI systems both in Run.

Note Do not put unit into IDLE mode or turn off the Thermo Scientific TII during

non-work hours. Doing so will allow bacterial growth and other contamination of the
water in the system. As a result, the system will require a lengthy rinse-up period at the
beginning of the workday to achieve high-quality product water.

Using your TII

DI Run Mode

4-4 TII Water System Thermo Scientific

DI Standby Mode

In STANDBY Mode, the DI pump will operate for ten minutes out of every hour (i.e 50 minutes
off, 10 minutes on). Every fourth time that the pump turns on, the UV lamp will also turn on for 10
minutes (i.e 3 hours 50 minutes off, 10 minutes on). This will allow the unit to produce high quality
water quickly upon being placed in the RUN Mode. It is recommended that the Thermo Scientific
TII be placed in STANDBY mode during non-work hours. At the end of the work day, press the
STANDBY switch to place the unit in STANDBY mode. Also, in STANDBY mode, the RO
operation automatically turns on to fill the reservoir as needed, and the RO system returns to
STANDBY once the reservoir is filled.

Figure 4-4 DI Standby Mode Screens -

a) DI and RO systems both in Standby,
b) DI system in Standby and RO system in Run.

Automatic Flush (RO Membrane)

In the Standby Mode, the Thermo Scientific TII will initiate a four minute automatic flush of the
RO membrane once every three hours and fifty-six minutes of operation. This prevents buildup on
the RO membrane. A timer in the Thermo Scientific TII counts the hours power is applied to the
unit. When the timer reaches three hours and fifty-six minutes, the Thermo Scientific TII initiates a
four minute flush if the unit is in the RUN or STANDBY Modes. If the unit is in IDLE, the
automatic flush will occur immediately after the START/STOP switch is pressed and RUN Mode
entered. The timer will reset to zero when the four minute automatic flush is completed.

Note Each time the RO system automatically turns ON, in RUN or STANDBY mode,

the RO membrane will flush water to the drain for 30 seconds prior to filling the reservoir.

Note If the unit is in STANDBY and power to the unit is turned off or lost, the unit will

return to STANDBY once power is restored.

Note Press the START/STOP switch to cancel a flush.

Maintenance and Servicing

Resetting Routine Timers

Thermo Scientific TII Water System 5-5

UV Lamp Replacement

The ultraviolet lamp requires periodic replacement. Lamp life will vary according to the number of
times the Thermo Scientific TII is turned on and off. Lamp life is based on the Thermo Scientific TII
being operated in the normal recirculating mode during regular working hours and then placed in the
Standby mode during off hours. Every fourth time the pump goes on in the Standby mode, the UV
light will go on. If the Thermo Scientific TII is cycled between the RUN and STANDBY modes
during the workday, this will result in a shorter lamp life. Therefore, it is recommended that the
Thermo Scientific TII be left in the normal RUN mode during regular working hours.

To replace the UV lamp, see UV Lamp Installation procedure in this manual.

Resetting Routine Timers

Procedures to reset all routine timers follow.

Prefilter, MPS, Carbon, Membrane, Pack Timers

These timers record service time to ensure the reliability and to reduce the risk of bacterial
contamination. The Prefilter, MPS, Carbon, Membrane and Cartridge Pack Timers must all be reset
prior to initial operation and after cartridge replacement. See

Routine Care Alerts for more details.

Reservoir Vent Timers

The Reservoir Vent Timer will alert the user when the reservoir vent filtering capacity has expired,

six months from initial use or when the timer has been reset. The user must reset the Reservoir Vent
Timer each time the Ventgard filter element (25001-DB) is replaced.

System UV Timer

The user must reset the System UV Timer each time the UV lamp in the Thermo Scientific TII is
replaced. This will reset the UV timer for approximately six months calendar time.

Reservoir UV Timer

The user must reset the UV Timer each time the UV lamp in the Thermo Scientific TII storage
reservoir is replaced. This will reset the UV timer for approximately one year calendar time.

Sanitization Timer

The Cleaning Timer will automatically reset itself after a successful cleaning procedure. If the user
decides to manually reset the cleaning timer, follow procedure in table below. This will reset the
cleaning timer for approximately one year calendar time.

Ordering Consumables and Supplies

Consumable parts are those required to support the day-to-day operation of this equipment. We
establish two types of consumables; those items that must periodically be replaced to maintain
performance (filters, resin cartridges, etc.) and other items of limited life (fuses, etc.) that you can
expect to replace on a more or less random basis. Where practical, we recommend the frequency of
replacement, or provides information on life expectancy from which you may calculate a replacement
interval compatible with your usage pattern.

The replacement of consumable parts is discussed in the Maintenance and Servicing section to assist
you in accomplishing your own service.
Consumables may be ordered separately and in some cases, as an expendables kit. Check with a
Technical Services representative for additional information on the expendables kit.
