1 INTRODUCTION
QUANTUM DI WATER HEATER
TREBOR’s Quantum deionized water heater will meet your most stringent
application requirements for process cleanliness and temperature control.
Our unique heater design virtually eliminates the potential for metal
contamination due to potentially exposed metal heating elements in
immersion style heaters, while process control and reliability are designed
to outperform and outlast other available quartz heating systems.
Trebor’s DI water heater uses a revolutionary heating technology to
provide exceptional process purity and control. Heat is generated using
resistive heating elements conducted to the fluid through quartz tubes
using convective heat transfer. This conductive / convective heating
method allows the heating element to operate at a much cooler
temperature than IR heating systems and provides the basis for a
responsive heating control system.
The Quantum heater modules have smooth surfaces with minimal cracks
and crevices, reducing particle traps. Furthermore, no pipe threads or
elastomeric O-rings are used. With the exception of the exposed tip of
the titanium temperature sensor (included with the fast response option),
the DI water is exposed only semiconductor grade quartz, PTFE, and
PFA wetted surfaces.
Trebor’s patented heating module technology is constructed to provide
excellent process control by minimizing hold-up volume and thermal heat
capacitance while maximizing the heat transfer. While heating, the
system can ramp to a process temperature in a “no flow” condition. The
ability to withstand these extreme transient conditions allows the heater to
operate without the need of flow monitors or flow switches to protect the
heaters. This also reduces the consumption of DI water by minimizing
temperature transition time and bypass to drain requirements.
Many product safety features have been incorporated into the Quantum
heater. Each system has a liquid level sensor, leak sensor, grounded
heater modules, ground fault protection, and redundant control system
interlocks. An electro-mechanical contactor disengages power to the
heaters when a fault condition occurs.
This equipment is built and certified to semiconductor manufacturing
industry requirements of SEMI S2-0703. Please contact Trebor
regarding any questions.
Conformity of the equipment with the above guidelines is attested by the
TUV certification mark.
This equipment complies with the requirements of the EU guidelines:

PAGE 4 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
Figure 1-1: 89/392/EEC “European Machinery Directive”
89/336/EEC “European EMC Directive”

CE mark.
This equipment also complies with the requirements of the “Management
Methods for Controlling Pollution of Electronics Information Products”,
known as “China RoHS”.

PAGE 6 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
2 SAFETY
This section describes information that is important for safe equipment
operation. Included is a listing of message conventions used in this
manual, as well as equipment safety interlocks, push buttons, and labels.
The equipment described in this manual uses hazardous voltage
electricity that can be dangerous. Only personnel trained in the
procedures and safety messages outlined in this manual should install (if
applicable), operate, or maintain this equipment. Read and understand
this manual before installation or operation of the system. Follow all
recommended practices and procedures that apply to your actions and
conduct. All safeguard devices must be in place when equipment is in
operation. Operators, set-up operators, helpers or installation personnel
should not alter, remove or disable safety equipment. When using this
equipment, be sure to follow the safety procedures outlined by your
facility. These safety procedures should cover the two primary types of
hazard training: (1) equipment hazards and (2) facility-related hazards.
2.1 SAFETY MESSAGE CONVENTIONS
Safety messages contained in this manual; Dangers, Warnings, and
Cautions, are highlighted for quick identification.
2.1.a Danger
A Danger message indicates an imminently hazardous situation that, if
not avoided, will result in death or serious injury. Messages identified by
the word Danger are used sparingly and only for those situations
presenting the most serious hazards.
2.1.b Warning
A Warning message indicates a potentially hazardous situation that, if not
avoided, could result in serious injury. Following is a typical example of a
Warning message as it could appear:

QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL PAGE 7
2.1.c Caution
A Caution message indicates a potentially hazardous situation, which, if
not avoided, could result in minor or moderate injury. It may also be used
to alert against unsafe practices. Following is a typical example of a
Caution message as it could appear:
Caution
Hot Surface
Do not touch. Can cause
skin burns upon contact.
Disconnect and lockout
power and allow surface to
cool before servicing.
2.2 EQUIPMENT SAFETY
The rest of this section describes equipment safety features:
Emergency Off Push button (EMO)
Process Interlocks
Main Power Disconnect Switch
Lockout/Tagout Information
Equipment Safety Labels
2.3 EMERGENCY OFF (EMO)
The EMERGENCY OFF button (EMO) is located on the front of the door.
When the EMO circuit is activated by pushing the button in, the
equipment will be placed into a safe shutdown condition. The EMO will
de-energize the heaters and process interlock devices. Other devices on
the panel remain energized and hazardous voltages will be present on
the power supply and power supply fuses, sub panel circuit breakers and
contactors. Use the Main Power Disconnect Switch to remove power
from the panel.

PAGE 8 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
Figure 2-1
On power up or after the EMO has been pushed, the heater must be
reset by pressing the blue RESET button to reactivate the controls. This
must be done at the machine.
2.4 PROCESS INTERLOCKS
The process fault interlocks are latched into the logic controller (PLC)
memory. When a fault occurs, the user interface will display the alarm
condition and the horn will sound. Pressing the RESET button will
silence the audible horn. The system will retain the fault until it is cleared.
Pressing the RESET button may restart the heater. If the indicator LED’s
remain illuminated then one or more faults are still active. Refer to
Section 8, Troubleshooting.
CAUTION: The interlock circuit does not remove hazardous
voltage from the circuit breakers, contactor, and the control transformer.
Only authorized, qualified, trained personnel should service this
equipment.
2.4.a Low Pressure Switch Interlock
The pressure switch will disengage power if system inlet water pressure
drops below 15 psig (103 kPa). The heater will come back online if the
pressure recovers within a 30 second time period. This prevents
nuisance trips due to transient conditions in the DI water supply while still
protecting the heater. However, erratic process temperature control may
result if heater power is disengaged during the pressure transient.

QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL PAGE 9
2.4.b Liquid Level Sensor Interlock
The Liquid Level Sensors will disengage power to the system if the
heater modules are not full of water or if boiling in the heating module
occurs. The heater will reengage if fluid is present within a 30 second
time period. This prevents nuisance trips due to transient conditions in
the DI water supply while still protecting the heater during startup. It is
critical that these sensors operate properly. Do not tamper with the
sensors. Damage to the system can result if the sensors are altered or
overridden.
NOTE: On the dual output option, this interlock will protect the heaters it
monitors (i.e. sensor 1 will protect the modules supplying output 1).
2.4.c Element Over Temperature Protection
The temperature limit controller monitors a thermocouple attached to the
heater element. In the event that the element temperature exceeds the
normal operating temperature, the system will immediately disengage
power and alarm. If this occurs, check element continuity before
continuing normal operation. See Section 7.1.a.
2.4.d Leak Sensor
The Leak Sensor will disable heater power immediately when water is
detected in the leak tray. Fix any leaks and dry the leak sensor and leak
tray prior to turning power on to the system.
2.4.e Overpressure Burst Fitting
The overpressure burst fitting (“Relief Drain”) is connected in-line with the
cold DI inlet port to provide a mechanical safeguard against possible
overpressure damage. Do not operate the heater above 414 kPa (60
psig).
If the overpressure relief device opens, the low-pressure sensor will
alarm. A periodic visual inspection of the fitting is recommended. Refer
to Section 7.1.g on replacing burst fitting.
2.5 LOCKOUT / TAGOUT
2.5.a Preliminary
Before installation or servicing the DI water heater, the facility’s power
source to the heater must be de-energized to prevent serious injury to
personnel and equipment. An authorized employee representing the
facility installing the DI water heater must follow approved company
guidelines and lockout or use suitable means to prevent re-energizing the
electrical system during installation or servicing.

3.1 UNPACKING
Remove heater system from crate and inspect heater cabinet for any
signs of damage (dented panels, paint scratches, etc.). Shock indicators
on the heater cabinet should be checked for rough handling during
shipment. Any damage to the system should be reported to the carrier
immediately.
Front door keys are not shipped with the system. Keys are available
upon request. (Key, Handle, 'L' LOC, [PROLINE] #98003360/B).
CAUTION: Heavy Object. When lifting or moving the system,
follow safe heavy object handling methods to prevent injury.
Be careful to not damage the drain fitting located under the heater
cabinet when using a dolly or forklift.
3.2 LOCATION
Locate the heater near the point-of-use to reduce plumbing heat loss.
Access to the front and rear of the system will be necessary for
maintenance and hook-up.
3.3 HOOK-UP
All utility hook-ups associated with the DI water heater are easily
accessible and are referenced in the Appendix.
After positioning heater at operating location, adjust the four leveling feet
until the heater is level and stable.
Connect the cold DI supply line to the “Cold DI Inlet” connection.
Connect the hot DI process lines to the “Hot DI Outlet” connection.
Use only hot DI compatible plumbing components. They must be
rated at a minimum of 110°C (230°F) and 414kPa (60 psig).
NOTE: It is recommended that the hot water supply line have a bleed, or
purge, at the point-of-use to reduce the possibility of the DI water
becoming stagnated in the heaters when not in use. The amount of this
bleed is best evaluated on a case-by-case basis, taking into account
each user’s criteria and production standards.

PAGE 14 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
Recommendation: Either insulate the hot DI water process line or
place a Hot Surface hazard warning (example shown below) on the
tubing every 20 feet. Conform to local codes while evaluating hot
water line routing.

PAGE 16 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
3.3.b Changing Heater IP Address
ATTENTION: This section of the manual assumes you know the basics
behind IP addressing. If you are unfamiliar with IP addressing, do not
attempt to change the IP address of the heater. Incorrect assignment of
an IP address could leave the Ethernet functionality of the heater
unusable by your current network configuration.
The heater ships with an IP address already assigned to it. The current
IP address of the heater can be viewed and changed from the heater
touch screen.
To view the current IP address and subnet mask of the heater, go to the
configuration screen in the touch screen. The IP address and subnet
mask are shown in the center of the screen.
To change the IP address of the heater, press the “IP Addr” button on the
right hand side of the configuration screen (see Section 4.2.e). A window
will open that will allow you to change the IP address and subnet mask of
the heater. Pressing the “Enter” button assigns the new IP address to
the heater. If you wish to cancel the changes made press the “X” button
at the top right of the window.
Please note that the new IP address is assigned as soon as the “Enter”
button is pressed. The previous IP address will also remain active until
power to the heater is cycled.
NOTE: Changing the IP settings may cause a WIN CE warning message
to appear. This warning is non-critical, and the heater will continue to
operate normally. To eliminate this warning message, do not hit “OK” or
“Cancel”. Instead, simply tap anywhere in the touch screen, outside of
the warning message.

QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL PAGE 17
4 OPERATION
4.1 GENERAL
The Quantum is very easy to operate. Once DI water is flowing through
the system and power is turned on, a process temperature can be
selected and power switched on to the heater modules. The controls will
do the rest.
If there is a problem with the DI water heater, the system controller will
notify the operator that the heater requires attention. After the fault
condition is corrected, the heater can be reset using the RESET button
located on the heater door (the fault condition will also be cleared if the
entire system power is cycled off and on). Redundant hardware relay
interlocks back up heater element temperature, leak sensor, and
component temperature faults.
4.2 DIAGNOSTIC DISPLAY
A color touch screen provides an intuitive interface to the DI water heater.
The heater can also be operated using both hardware and software
remote interfaces (depending on the heater options). The display is
divided into several pages. The pages are designed to be simple and
easy to understand. The display contains a total of six pages.
4.2.a Main Page
Figure 4-1: Main Screen (single & dual bank version shown)
The main page is the first page that is displayed after the heater is
powered on. This page is designed to show you the current status of the
heater at a glance. The set point, process value, duty cycle, alarm
conditions, heater module errors, and internal communication status are
displayed.
This page also contains a button to turn the heater on and off, a button to
change the set point and enable and disable of the heater.

PAGE 18 QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
An enable button is provided that, when activated, will open the inlet valve
and allows the heater bank to be turned on. This function is active in
single and multiple output systems. This feature provides the ability to

If the heater module temperature is shown in black lettering with a white
background, the module is functioning properly. If a heater module
temperature is displayed with blue lettering, the heater is running too cool
compared to the other heaters in the bank. If a heater module
temperature is displayed with red lettering, the heater is running too hot.
Heaters running too hot or too cold should be checked as soon as
possible. See Section 7.1.a.
The numbered buttons bellow each temperature status box correspond to
the heater modules. These buttons enable or disable each modules
thermocouple. When enabled, the thermocouple is considered in the
temperature control algorithm and is monitored for the Thermocouple
Open Alarm condition (see Section 4.2.b).
The buttons on the bottom of the page will take you to the other pages.
