2. Introduction
While the o󰀩cial language of the “Original Instructions” is in English, any interpretation
of this Instruction Manual in other Community languages will be discussed by the
manufacturer (Heateex) and the customer on an as required basis.
Your new Aquarius® DIW heating system is engineered to o󰀨er a safe, reliable, and
e󰀨ective solution to de-ionized heating needs by providing at temperature ultrapure
DIW. These systems are designed to reduce water usage as well as maintain high purity
requirements. This has been achieved using our patented Heateex heaters and Power-
to-Flow®Control system.
Heateex’s patented Power-to-Flow®Control system eliminates undesirable overshoots
or drops in temperature, which are commonly the result of inadequate PID temperature
controllers. Aquarius® systems are designed to maintain accurate user-specied
temperature even with process ow rate variations and during recirculation (Systems
equipped the recirculation option only). The Power-to-Flow®Control system compensates
for changes in the process ow rate by measuring the ow rate of the uid as it enters
the heaters, measuring the temperature at various stages in the heating process,
and adjusting the proportion of power applied to each heating zone based on those
measurements. This integrated control method is advancement to previous methods of
temperature control that reacts quickly and robustly to any variations in ow, providing a
steady supply of ultra-pure DIW at a stable temperature.
High purity is maintained throughout the heating process due to the use of PVDF, FEP,
and PFA wetted surfaces. Aquarius®systems are equipped with many safeties and to
protect the heater modules from unnecessary damage due to overheating, including:
All Aquarius® systems come standard with a pressure by-pass protect against over
pressurization of the unit. Shorted SCR sensing has been incorporated in the Aquarius®
for added heater protection. A Safety Relay, Safety PLC and GFCI are standard on the
Aquarius®which provides added protection to the unit and for operators. To monitor the
purity level of the exiting heated DIW, a resistivity sensor is available as an option on
Aquarius®systems. The Power-to-Flow®Control system also incorporates the use of a
visual touch screen user interface which is straightforward and easy to operate with only a
few adjustments needed after initial settings are entered.
• Thermocouples
• Liquid level sensor
• Flow sensor
• Pressure transducer
• High-limit sensors
• Thermal cut-o󰀨 sensors

1. Emergency O󰀨 (EMO) button - An EMO button located on the front of the unit (and
remotely if option is selected) is utilized by the user in the event of an emergency
condition to shut power to the unit (and other devices if option is selected). It is a SEMI
S2 compliant device with a direct opening action mechanism, and safe break action.
2. Door Interlock Switch - A door interlock switch mounted to the front cabinet door is
used to indicate if the door is open or closed. If the front door is open, the power will be
cut to the unit. This safety device features force guided contacts and a tamper resistant
mechanism.
3. Safety Relay – The Safety Relay monitors both the EMO button and the Door
Interlock Switch. The Safety Relay incorporates redundant relays in conjunction with
the emergency o󰀨 button switch and the safety open-door interlock to achieve safety
category 3. The Safety Relay determines whether or not to provide power to the unit.
4. Ground Fault Circuit Interrupter (GFCI) – GFCI monitors heater amperage and any
circuits containing 120 volts or more if a suspicious current leak is detected in circuitry.
5. Thermal Cut-O󰀨 Sensor – The thermal cut-o󰀨 sensor is a thermal sensor which opens
once it’s breaking temperature is exceeded. It is used to shut down the heater when a
runaway heating condition occurs.
6. Safety PLC (Programmable Logic Controller) - Safety PLC monitors high-limit
thermocouples, GFCI, and Thermal Cut-o󰀨 Sensor status using redundant force guided
relays, and controls the Heater Master Relay (which controls the heater contactor) and
the Heater Safety Relay (which controls the SCR output signals to the heater).
7. Pressure Relief Valves – Pressure relief valves are installed at the input and output of
the unit to relieve pressure if it exceeds the pressure relief set value which protects the
plumbing components of the unit and personnel.
8. Water Leak Deluxe (Optional) – The water leak deluxe option consists of monitoring
for system leaks via water leak sensor and isolation valves which shut o󰀨 the incoming
process uid and the heaters as well. This option allows the user to isolate and reduce
a pressurized system to a zero-energy state prior to maintenance or service work. The
system uses two pneumatically or manually operated 2/2-way diaphragm valves to
isolate the system. The valves are located at the input and output. (Optional).

Every e󰀨ort has been made to ensure that this unit will run with a minimum of user input
or maintenance. However, there are still precautions to be taken whenever operating,
performing maintenance, or servicing this unit. This unit makes use of heating elements
and electrical components, both of which pose inherent burn, re, and electrical shock
hazards. These hazards can result in injury to personnel, the plant, and/or the process.
Please note the following to aid in the operation of your unit and to decrease the risk of the
above-mentioned hazards.
Precautions:
• Carefully and completely read through this and all accompanying literature completely
to verify that you understand the functionality and features of this system. Please
become familiar with the integral safeties and controls within this system, and know their
functions.
• Always disconnect all electrical power prior to installing, servicing, or replacing
electric heating elements and/or assemblies. The means for disconnection must be
incorporated in the xed wiring in accordance with the wiring rule.
• Electrical termination enclosures should be selected to match the application’s
environment and be able to withstand worst-case failures, especially in hazardous
locations.
• Avoid re hazards. Electric heaters and their components can develop temperatures
that produce an auto-ignition source. Avoid mounting heaters in atmospheres containing
combustible gases, vapor, or dust.Article 501 of the National Electrical Code (NEC)
requires that the maximum sheath temperature when the heater is continually energized
not exceed 80 percent of the surrounding atmosphere’s auto-ignition temperature.
• Avoid having heaters come in contact with combustible materials. Keep heaters far
enough away from combustible materials to prevent ignition.
• Be aware of the labeling on the unit, such as a lightning-bolt warning symbol, which
alerts you to a safety hazard that could harm you or the unit.
• While servicing or operating this unit it is advisable to remove all metal from the
individual working on the unit. This includes metal bracelets, rings and jewelry, as well
as metal rim glasses and wristwatches.
• Keep your clothing, hands, and feet dry at all times whenever working with electrical
equipment.
• Pull the fuses, open the circuit breakers, or disconnect the circuits from their source of
power to protect yourself, the test equipment and the equipment under test.
• Do not troubleshoot or service a circuit with the primary power applied.
• If it becomes necessary to work on the unit with the power applied, keep one hand free
at all times (behind you).

Subject to change without notice
• Ensure no power applied to a circuit when making continuity or resistance checks.
• Use the correct tools (i.e. screwdriver, alignment tool, etc.) for the job.
• Do not use metal tools around the connectors when there is power to the unit, as they
may cause arcing.
• Turn o󰀨 power before connecting alligator clips to any circuit.
• Do not take anything for granted when working with inexperienced help. Check every
operation before they perform it.
• The operation of this unit creates large amounts of heated process uid. This uid is
likely to be heated to temperatures above the threshold of safety for human contact.
Please be advised of this and take the necessary precautions whenever connecting or
disconnecting any plumbing from the system. If you are ever in doubt, turn the unit o󰀨,
and wait an appropriate amount of time before performing any operations or service
involving the plumbing.
• The process uid within this system may also become pressurized from outside ow
sources. It is the user’s responsibility to verify that pressure within the system has been
relieved externally; in order to prevent exposure to hazardous uid such heated de-
ionized water, or heated chemicals and/or acids.
• This unit has several safety interlocks integrated within the system. However, it is the
user’s responsibility to verify that incoming power has been disconnected from a remote
source prior to opening or servicing the unit. This is advised to prevent user exposure to
high voltage and current, and reduce the risk of electric shock.
• The function of this unit is to heat process uid for use in ultra-pure operations.
Therefore during normal operation the unit will accumulate heat within the plumbing and
the heater compartment. It is our recommendation that the unit is allowed a su󰀩cient
amount of time to cool before any maintenance or inspections are made to the unit in
order to prevent user exposure to heated surfaces or air.
• The processes in which this unit is intended involve heated uids. Whenever heated
uids are involved, certain precautions must be taken in order to avoid user injury. This
is especially important since it is most likely that this unit will be used with aggressive
uids that can further harm or injure an individual, such as deionized water and process
acids. User exposure to these types of materials can result in burning, scalding, and in
some cases deep tissue damage. To avoid injury it is the user’s responsibility to take
the appropriate precautions as outlined above, and in all cases dealing with heated or
aggressive materials, to use the appropriate safety equipment, such as but not limited
to safety goggles and glasses, and chemically resistant gloves and garments.
• This heater is not intended for use with any liquid other than DIW.
• The heater is not intended for use with ammable liquids. Use of this equipment with
ammable liquids will greatly increase the re risks of the system.
Whenever servicing this unit, at least 300 lumens of light is required;
otherwise use portable lighting that does not have to be held.

Before shutting down the Aquarius®system verify that doing so will not adversely
a󰀨ect other equipment, machinery, and/or processes and that it is safe to do so. Prior
to powering down the system, place the Aquarius®control system into Standby mode.
(Refer to the PF3000 controller manual for more detailed information.) Once the unit is in
Standby mode, power down the system by pressing the OFF button which is located on
the front of the Aquarius®system. The indicating lamp on the ON button will de-energize
and the touchscreen will turn o󰀨. Please note that electrical power will remain present
within the system until the Aquarius®system has been disconnected from the electrical
energy source. To turn on the unit, simply press the ON button located next to the OFF
button. The Aquarius®system will always power up in the Standby mode.
It is ultimately the responsibility of the user to verify and provide adequate isolation of all
energy sources, i.e. electrical power, pneumatic air (CDA) and DIW. The process uid
within this system may become pressurized from outside ow sources. It is the user’s
responsibility to verify that pressure within the system has been relieved externally prior to
servicing, in order to prevent exposure to hazardous uid, in this case, heated de-ionized
water.
Certain energy isolation devices may be provided with the Aquarius®system as an option,
such as an electrical disconnect switch and/or pneumatic AOV valves for process uids. If
provided, the electrical disconnect switch will be mounted in an enclosure located on the
back of the Aquarius®system. If provided, the pneumatic AOV valves will be located inside
the enclosure in the heater/plumbing section. While energy isolation devices may be
provided with the Aquarius®system, it is the responsibility of the user to determine if these
options are su󰀩cient and safe based on their requirements.
If the unit is to remain powered o󰀨 for an extended length of time, it is recommended to
disconnect and isolate all energy sources to the Aquarius®system, such as electrical
power, pneumatic air (CDA) and DIW.

To reduce the possibility of unanticipated problems, the Aquarius®system should be
thoroughly checked every 6 months. A thorough inspection should consist of a check
for leaks, conrm correct operation interlocks, and verify calibration.
1. Leak Check
• Open door or remove side panels (left or right)
• Pressurize the unit (65 psi. MAX)
• Check all plumbing connectors. If there is a leak, x or replace the components.
Aquarius®systems are controlled by the PF3000, a PLC-based controller. The
controller’s basic function is to control the discharge temperature of the water.
Additionally, it monitors temperature, ow, voltage, pressure, and resistivity (optional)
and provides safety interlocks for the unit.
2. Safety Check
To check Safety PLC’s safety circuits, open the controller panel; disconnect one
sensor lead wire from the Safety PLC (ow sensor, liquid level sensor, pressure
sensor or thermocouple). Note: Opening the cabinet will cause the Door Interlock to
trigger shutting down all power to the unit and preventing the unit from starting up.
Contact the factory for additional information. The controller should sound an alarm
signal indicating an open analog sensor or open thermocouple. Reconnect the sensor
to the correct terminal after testing. Test the sensors one at a time. If no alarm sounds,
the controller may be defective, contact the factory or replace the controller.
3. Check Safety PLC’s Calibration
• Input Thermocouple
• Process Thermocouple
• Flow Sensor
• Pressure Sensor
• Voltage Transducer
• Resistivity (Optional)
Calibration can be adjusted in the System Set Up ► System Calibration.
A user password is required to modify these values.
Few bacteria live or grow in temperatures in excess of 70°C. However,
incoming bacteria may ourish where water is allowed to cool or stagnate
in the plumbing unless adequate sanitizing procedures are employed.
Aquarius®systems are compatible with most common sanitizing agent.
The system should be disinfected on the same schedule and with the
same procedures as the main DIW distribution network.

Verify that the specic sanitation method
is compatible with the O-ring material
selected. The table (right) indicates
examples of acceptable means of
sanitation with a given O-ring material
for Aquarius®systems. Consult factory
to verify other means.
We recommend that users follow proper
decontamination and decommissioning
procedures when removing Aquarius®
systems from service. Please contact us
for recommendations on proper disposal
or qualied dismantlers in your area.
Aquarius®systems features an Auto Purge option that reduces the potential of bacteria
growth in the DIW or process uid and Aquarius®plumbing system. The purge feature
of the Aquarius® can be activated or used three di󰀨erent ways:
1.Automated using the PF3000 control logic.
2. Manually through the use of the HMI/Touch screen interface.
3. Remotely through a communications interface.
Heating DIW or process uid is not permitted while the system is actively purging.
Please refer to the PF3000 controller manual for more information on the operation of
the Auto Purge feature and HMI/Touch screen operation of the Aquarius®system. The
Auto Purge feature is not available on Aquarius®systems with the recirculation feature.

Aquarius®systems with the optional recirculation feature have a built-in recirculation
system and are equipped with an ultra–pure PFA-PTFE bearing-less pump, pump air
cooling system, and safety interlocks. The pump is controlled by a PLC. The Aquarius®
recirculation feature is optimized for precise DIW temperature control during recirculation,
and provides hot DIW at temperature on-demand. The recirculation feature reduces heat
up time by implementing controlled heating at instances when demand is not required.
When demand is needed, the Aquarius®system returns to single pass mode and is ready
to provide DIW at the specied temperature.
In addition to saving process time, Aquarius®recirculation feature also reduces DIW usage
which is an added cost savings for waste water and energy. The ability of the Aquarius®to
provide an instant supply of heated DIW negates the requirement for a trickle ow, which
is commonly used by DIW heaters to maintain pre-demand water temperature. Aquarius®
recirculation feature will also discourage bacteria growth from forming in the process uid
and Aquarius®plumbing, which is essential in maintaining high purity requirements.

11.1 Recirculation Operation
The status of the Aquarius®system with Recirculation is indicated on the System Status
screen of the user interface. To access the Recirculation sub-menu, press the Recirculation
key (∞). The Recirculation key is located at the bottom left of the System Status screen. The
three di󰀨erent modes of the Recirculation System are illustrated by a series of labels and/or
illuminated green indicating lights. These three modes are:
1. Demand: This is the default mode of the system. The Recirculation System is not active
and the uid is being sent to process.
2. Venting: The Recirculation System is preparing to initiate and is lling the pump and
plumbing with uid and/or evacuating any air/bubbles from the plumbing. This mode will
activate anytime excessive air/bubbles are detected within the recirculation plumbing.
3. Recirculation: The Recirculation System is active and no uid is being diverted to
process. An external signal is required in order to initiate this mode.
The Aquarius® system has been congured to default to the “Demand” mode.
To place the Aquarius®into Recirculation mode several conditions must occur:
1. The Recirculation System must be enabled.
2. A customer provided “Recirculation Signal” is required to send the system into the
Recirculation mode.
3. The Venting mode cannot be active.
If the above conditions are not met, the system will fail to enter “Recirculation” mode and
remain in “Demand” mode. Please note that the presence of any “critical” alarms will abort
recirculation by shutting o󰀨 the pump and deactivating the heaters. Once “critical” alarms are
resolved, recirculation will automatically resume but the system will be in “Standby” mode
and the heaters will remain OFF until the system is placed back into the “Active” mode.
Please follow all Pre-Installation Preparation, Installation, Suggested Operational Inspection
procedures and the Pump Air Cooling System Set Up and Calibration prior to activating
recirculation. This includes the connection of an external maintain switch/signal to the
Aquarius®“Recirculation Signal”. The Recirculation Signal is available for Discrete and
Ethernet communication connections. Please refer to the specic Electrical Component
Layout drawing and the Electrical Schematic drawing for more information.
To initiate the Recirculation mode from Demand mode:
1. Recirculation System DISABLED / ENABLED key located on the System Status screen
enables/disables the Recirculation System. To enable the system press the DISABLED
key. The “Disabled” label will change to “Enabled” and will be illuminated yellow.
2. Provide a closed “Recirculation Signal” to the system to initiate the “Recirculation” mode.
To return back to the Demand mode from the Recirculation mode:
1. Provide an open “Recirculation Signal” to the system to initiate the “Demand” mode.
Note: If Recirculation System is disabled, “Recirculation Signal” has no a󰀨ect on recirculation.
