Type II Water System 1-1Thermo Scientific
Section 1 Safety Information
Your Thermo Scientific TII has been designed with function, reliability,
and safety in mind. It is your responsibility to install it in conformance
with local electrical codes. This manual contains important operating and
safety information. The user must carefully read and understand the
contents of this manual prior to the use of this equipment. For safe
operation, pay attention to Notes, Cautions, and Warnings throughout the
manual.
Water purification technology employs one or more of the following:
chemicals, electrical devices, mercury vapor lamps, steam and heated
vessels. Care should be taken when installing, operating or servicing
Thermo Scientific products. The specific safety notes pertinent to this
product are listed below.
Warnings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Do not locate the Thermo Scientific TII directly over equipment that
requires electrical service. Routine maintenance of this unit may
involve water spillage and subsequent electrical shock hazard if
improperly located.
3. Replace fuses with those of the same type and rating.
4. Do not disassemble water lines or remove cartridges where spilled
water could contact equipment that requires electrical service.
Electrical shock hazard could result.
5. Power unit OFF before plugging in or unplugging unit.

Safety Information
6. Disconnect from the power supply prior to maintenance and
servicing.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials;
fire or explosion may result. This device contains components that
may ignite such materials.
2. Do not use in the presence of highly corrosive substances such as
bleach or acid baths; fire may result.
3. This device is to be used with water feeds only. Cleaning agents must
be used in compliance with instructions in this manual. Failure to
comply with the above could result in explosion and personal injury.
4. Avoid splashing cleaning solutions on clothing or skin.
5. Ensure all piping connections are tight to avoid chemical leakage.
6. Ensure adequate ventilation.
7. Carefully follow manufacturer's safety instructions on labels of
chemical containers and material safety data sheets.
8. This unit is equipped with an ultraviolet lamp. Ultraviolet radiation is
harmful to the eyes and skin. Do not attempt to observe the lamp
directly.
9. Refer servicing to qualified personnel.
Do not use this product for anything other than its intended usage. If the
equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Note The UV lamp contains mercury. If broken or no longer needed, do
not dispose of the UV lamp in the trash. Recycle or dispose of the UV
lamp as hazardous waste. s

Type II Water System 2-1Thermo Scientific
Section 2 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.
Note The TII is not shipped with pretreatment and DI polishing cartridges
or a final filter. These must be ordered separately. The start-up kit
containing these components can be ordered using part number D502138
for all units. s

Note Also required for installation (purchased separately):
1. A storage reservoir. If a Thermo Scientific TII storage reservoir
(D14061, D14062, D14063, D14064, D14071, D14072, D14073 or
D14074) is also purchased, see contents in separate box.
2. Start-up kit (D502138). Contains the Thermo Scientific TII DI
Cartridge Pack (with 0.2 μM final filter) (D502137), 1 μM Pre-filter
(D502113), MPS Cartridge (D502114), Extruded Carbon Cartridge
(D502115), and Cartridge Block (BK1404X2).
3. Customer-supplied fasteners to mount unit and remote display.
4. Household bleach for the cleaning process. s
Locate storage reservoir approximately 2 - 5 ft. (1.52 m) from the TII for
electrical connections.
Refer to the Thermo Scientific TII storage reservoir manual or customer-
supplied reservoir manual for mounting instructions. The outlet of the TII
storage reservoir must be above or at the same level as the inlet of the TII.

Locating Unit

Place the Thermo Scientific TII on a bench top that is accessible to
electricity and an atmospherically vented drain.
Wall composition, condition and construction, as well as fastener type,
must be considered when mounting this unit. The mounting surface and
fasteners selected must be capable of supporting a minimum of 150 lbs.
(68kg). Inadequate support and/or fasteners may result in damage to
mounting surface and/or equipment. If you are unsure of mounting
surface composition, condition and construction or correct fasteners,
consult your building maintenance group or contractor. Refer to Section 2
Technical Specifications, for clearance requirements.
Warning Do not locate the Thermo Scientific TII directly over equipment
that requires electrical service. Routine maintenance of this unit may
involve water spillage and subsequent electrical shock hazard if improperly
located.
Install the Thermo Scientific TII on a wall in a convenient location that is
accessible to an atmospherically vented drain and electricity.
1. Locate the wall bracket packed separately from the unit.
2. Using the wall bracket as a template, locate and drill the mounting
holes in the wall. A minimum of four (customer-supplied) fasteners
will be required — two on the top and two on the bottom.
3. Attach the wall bracket to the wall using customer-supplied fasteners.
4. Remove the locking screws on each side of the wall bracket.
5. Pull the two locking slides on each side of the wall bracket out as far as
they will go.
6. Hang the unit on the wall bracket by sliding the mounting pins into
the wall bracket slots.
7. Push the locking slides on each side of the wall bracket in as far as they
will go.
8. Replace the locking screws.
Note The outlet of storage reservoir must be above or at the same level as
the inlet of the TII. s

Installation
The following instructions will apply when you need to attach a piece of
tubing to your Thermo Scientific TII during installation, unless otherwise
noted in the installation instructions. To make tubing connections:
1. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
2. Mark from end of tube an insertion length of 3/4” (1.9 cm).
3. Wet the tube end with water and insert the tube straight into the
fitting until it bottoms out on the interior shoulder and the insertion
mark is no longer visible.
1. Using the tool provided (AYX23), push the collet toward the body
while pulling on the tubing to release the tube, as shown in Figure 3-
15.

1. Completely disassemble the fitting. Refer to Figure 16 to familiarize
yourself with the names of the component parts.
2. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
3. Place the grab ring and back-up ring in the hex nut in the order and
orientation shown in Figure 16. Thread the nut onto the adapter. DO
NOT use the o-ring at this time.
4. Push the tubing through the nut until it bottoms out in the adapter.
5. Remove the adapter nut and tubing. Place the o-ring over the tubing.
Be careful not to push the back-up ring or grab ring further back on
the tubing when installing the o-ring.
Caution Do not tighten tube fitting hex nut with a wrench. Tight
connections can be easily made by hand. s
These fittings, shown in Figure 3-17, are found on the water inlet. To
insert the inlet tubing:
1. Press on the metal thumb pad on the coupling body to ensure the
fitting is open.
2. Wet the o-ring on the coupling insert and push into the coupling body
until you hear a click. Gently pull on the tubing to ensure it is secure.
3. To remove, press the metal thumb pad to release and pull coupling
insert out.
