Site

Facility Water

Requirements

Section III Installation

The unit should be placed in a laboratory or clean industrial environment with
easy access to a facility cooling water and a drain.

Limit the facility water inlet pressure to less than 150 psi (10,2 Bar) and
limit the facility water inlet pressure to outlet pressure differential
across the System IV to less than 35 psid (2,4 Bar).

Refer to the Cooling Capacity chart in Section II, Specifications. The flow rate
of the cooling water supply must meet or exceed these requirements for the
unit to operate at its full rated capacity. If the cooling water does meet these
standards, the cooling capacity will be derated. The chart is based on a 10°C
difference between the temperature of the cooling water supply and the pro­cess fluid entering the instrument being cooled.

As the heat load increases, the required flow rate of the cooling water supply
increases. For example, if the heat load is 60 kilowatts, only 20 gallons per
minute is required to remove the heat. However, if the heat load is 80
kilowatts, 26 gallons per minute is required.

The flow meter on the front of the unit does not measure the flow rate of the
cooling water supply. The flow meter measures the flow rate of the cooling
fluid returning to the instrument being cooled.

-7-

Electrical Requirements

Voltage Selection

(60 Hertz Units)

The unit construction provides protection against the risk of electric
shock by grounding appropriate metal parts . The protection may not
function unless the power cord is connected to a properly grounded
outlet. It is the user's responsibility to assure a proper ground connec­tion is provided.

Refer to the serial number label on the rear of the unit to identify the specific
electrical requirements of your unit.

Make sure the voltage of the power source meets the specified voltage, ±10%.

If the unit is to be operated from a 220 to 240 volt source, a voltage selector
inside the unit must be reset. See Section V, Service and Maintenance, for
instructions on changing the voltage selection.

NOTE Units rated 380-415 volt do not have a voltage selection switch.

Plumbing

Requirements

The plumbing connections are located on the rear of the unit and are labelled
FACILITY WATER and RECIRCULATING WATER. FACILITY WATER connec­tions are 1 inch nominal FPT. RECIRCULATING WATER connections are 1½
inch nominal FPT. See illustration on page 20.

Before installing the unit to an instrument that previously used tap water as a
cooling fluid, flush the instrument several times to remove any rust or scale
that has built up. The manufacturer of the instrument should be able to
recommend a cleaning fluid for their equipment.

Connect the FACILITY WATER SUPPLY to the cooling water source.
Connect the FACILITY WATER RETURN to the drain.

Connect the RECIRCULATING WATER SUPPLY to the inlet of the instru­ment being cooled. Connect the RECIRCULATING WATER RETURN to the
outlet of the instrument being cooled.

Flexible tubing, if used, should be of heavy wall or reinforced construction.
All tubing should be rate to withstand 80 psi at +40°C. Make sure all tubing
connections are securely clamped. Avoid running tubing near radiators, hot
water pipes, etc. If substantial lengths of tubing are necessary, insulation
may be required to prevent loss of cooling capacity.

-8-

Fluids

Tubing and insulation are available from Thermo Fisher. Contact our Sales
Department for more information (see Preface, After-sale Support).

It is important to keep the distance between the unit and the instrument being
cooled as short as possible, and to use the largest diameter tubing practical.
Tubing should be straight and without bends. If reductions must be made, they
should be made at the inlet and outlet of the instrument being cooled, not at
the unit.

If substantial lengths of cooling lines are required, they should be pre-filled
with cooling fluid before connecting them to the unit.

Never use flammable or corrosive fluids with this unit. Do not use
automotive anti-freeze. Commercial anti-freeze contains silicates that
can damage the pump seals. Use of automotive anti-freeze will void the
manufacturer’s warranty.

We recommend using distilled/deionized water with a 0.05 to 0.1 MOhmcm
reading.

Highly distilled/deionized water, above the 3 MOhmcm region, may
become aggressive and is not recommended for use with units with
wetted parts other than stainless steel. Distilled/deionized water in the
15 MOhmcm region is definitely aggressive and should not be used.
Units operating in these regions should be closely monitored. See
Water Quality Standards and Recommendations in the Appendix.

If you do not have access to distilled/deionized water we recommend using
filtered tap water. Thermo Fisher cannot recommend any custom fluids, these
fluids are too dependent on your particular application.

Below +8°C, a non-freezing solution is required. The selected cooling fluid
must have a viscosity of 50 centistokes or less. A 50/50 mixture, by volume,
of distilled/deionized water and laboratory grade ethylene glycol is suggested.

-9-

Filling Requirements

Auto Refill

Device (Optional)

Remove the top access panel and locate the reservoir. Fill the reservoir with
cooling fluid to within one inch of the top. Since the reservoir capacity is small
compared to the volume of the circulating system, keep extra cooling fluid on
hand until the circulating system is full.

The automatic refill device maintains the correct level of cooling fluid in the
reservoir. The device consists of a float switch in the reservoir and a solenoid
valve at the rear of the unit. If the cooling fluid level falls, the float switch will
drop, opening the solenoid valve and allowing make-up fluid to fill the reservoir.
Once the cooling fluid reaches the proper level, the float switch will rise and the
solenoid valve will close.

NOTE: For the solenoid valve to close properly, the minimum supply flow rate

should be 2.2 gallons per minute.

Connect the 3/8 inch OD stainless steel barbed fitting on the solenoid valve
to the make-up fluid source using 5/16 or 3/8 inch ID flexible tubing.

Flow Control

Auto Restart

Tubing is available from Thermo Fisher. Contact our Sales Department for more
information (see Preface, After-sale Support).

The RECIRCULATING FLOW CONTROL handle is connected to a three-way
valve that controls the flow of the cooling fluid to the instrument being cooled.
The handle is located on the front of the unit.

When the handle is in the “+” position, the valve is open and all available
cooling fluid is supplied to the instrument being cooled. When the handle is
in the “0” position, the valve is closed and no cooling fluid is supplied to the
instrument being cooled. When the handle is between these two positions,
the flow rate of the cooling fluid is between full flow and no flow. Use the
flow meter to adjust the desired flow rate.

The gauge next to the flow control handle indicates the operating pressure.

Units are equipped with an auto restart feature. If power is lost, the unit will
automatically restart when power is restored. This feature is enabled/
disabled using the controller's Tune Loop, see page 13.

-10-

Start Up

Section IV Operation

Before starting the unit, double check all electrical and plumbing connections
and make sure the circulating system (the System III, your application, and
the tubing that connects them) has been properly filled with cooling fluid.

Turn the RECIRCULATING FLOW CONTROL to “0”. Press START/STOP.
The pump starts and the controller displays the reservoir fluid temperature.

The low fluid level monitor in the reservoir prevents the unit from operating if
the fluid level in the reservoir is below the safe operating level. By slightly,
and/or intermittently opening the RECIRCULATING FLOW CONTROL
(toward “+”) and using extra cooling fluid to keep the reservoir topped off,
the system can be filled without repeated tripping of the monitor.

If the unit shuts down, top off the reservoir and restart it. When the system
is full, the reservoir level will no longer drop when the RECIRCULATING
FLOW CONTROL valve is opened (toward “+”).

A control valve, located in the FACILITY WATER inlet line, regulates the
flow rate of the cooling water supply as it enters the unit. The valve regulates
the flow rate based on the heat load. Flow through the unit stops automati­cally when the unit is shut off.

Temperature Controller

To turn the unit off, press START/STOP. The recirculation pump will stop.

The IDLE and COOL lights indicate the control valve’s status. When the
temperature control valve is wide open (for maximum cooling), the COOL
light is on steady. When the control valve is closed, the IDLE light is on. As
the control valve moves between these extremes, the two lights flash with
varying on-time to indicate the approximate position of the control valve.

-11-

Temperature Controller

The microprocessor controller controls temperature using a PID (Propor­tional-Integral-Derivative) algorithm. It is designed with self-diagnostic
features and easy to use operator interface.

NEXT ENTER

Use this key to accept and save changes.

YES,

This key is used to increase numerical values.

NO,

This key is used to decrease numerical values.

When the controller is powered it displays the reservoir fluid temperature.

Press the NEXT ENTER key to view the setpoint. The display flashes
between SP and the actual setpoint number. If desired, use the YES and NO

keys to change the setpoint. The display flashes as soon as either key is

depressed. Once the desired setpoint is displayed, press NEXT ENTER.

When selecting an operating temperature, remember that the lowest achiev­able temperature is a function of the available flow rate, the temperature of
the cooling water supply and the heat load.

The temperature control system actuates a control valve in the FACILITY
WATER line. The control valve adjusts the flow of the cooling water supply
to produce the desired operating temperature.

NOTE: The controller does not use the new value until the NEXT ENTER

key is depressed and the display stops flashing. The controller will not allow
you to enter a value above the maximum or below the minimum value, or
any illegal value. If you try to enter an illegal value the display will revert to
its original value when the last digit was entered.

If the NEXT ENTER key is not depressed within one minute, the controller

will time out and the new value will not be accepted. The controller will
revert to the previous value.

NOTE: Error codes are addressed in Section VI, Troubleshooting.

-12-

TuneLoop

The controller is used to tune the COOL PID values; configure the unit to
continue to run (Indc) or shut down (FLt) in the event of a fault; set the high
(Hit) and low (Lot) temperature limits; and enable/disable auto restart (Auto).
If a temperature limit is exceeded the controller will display an error code,
see Section VI.

NOTE: Serial Communication (SEr) is not operational. Ensure the display

indicates OFF.

With the controller displaying the fluid temperature, press and
hold the NO key and then press the NEXT ENTER key. The
controller will display tunE. Press YES to display CooL.

CooL is used to adjust the controller's PID values. However ,
Thermo Fisher recommends only a qualified technician change the
PID values. Incorrect values will hamper unit performance. Factory
set values are: P = 15; I = 0.3; D = 0.0.

Press NEXT ENTER to display the
alarm (ALr) prompt. Press YES to
display Indc and have the unit continue
to run in the case of a fault. Press NO to
display FLt and have the unit shut down
in the case of a fault. The factory preset
is FLt.

Press NEXT ENTER to display the
high temp (Hit) alarm setting. If
desired, use the arrow keys to
change the value. The factory
preset value is 55°C.

Setup Loop

Press NEXT ENTER to display the
low temp (Lot) alarm setting. If
desired, use the arrow keys to
change the value. The factory preset
value is -10°C.

Press NEXT ENTER to display the
auto restart (Auto) prompt. Use
the arrow keys enable/disable this
feature. The factory preset is ON.

Press NEXT ENTER to display the
serial comm (SEr) prompt. The
display should flash NO. If not, use
the arrow keys until NO is
displayed.

Press NEXT ENTER to display Stor, press YES
to accept all the changes, press NO to abort all
changes and restore all the previous values. The
controller will again display the fluid temperature.

Section V Maintenance & Service

For personal safety and equipment reliability, the following procedure
should only be performed by a qualified technician. Contact our
Service Department for assistance (see Preface, After-sale Support).

Thermo Fisher Scientific offers on-site Service Contracts that are designed to
provide extended life and minimal down-time for your unit. For more informa­tion, contact our Service Department (see Preface, After-sale Support).

The facility water strainer is the user-installed basket strainer on the

FACILITY WATER inlet. NOTE: The strainer is designed to be used only

with water. Clean the strainer when it becomes visibly clogged or dirty.

Disconnect the power cord from the power source and turn off the facility
cooling water.

Algae

Fault Interlock

Contact

Place a container under the strainer to collect any water that spills out of the
basket when it is removed.

Unscrew the clear plastic basket. Remove the screen and rinse it with water.
Replace the screen and the basket.

To restrict the growth of algae in the reservoir, it is recommended that the
reservoir cover be kept in place and that all circulation lines be opaque. This
will eliminate the entrance of light which is required for the growth of most
common algae.

A set of contacts is connected to a receptacle on the control panel. The
contacts are rated 10A/240V. This is not a power inlet or outlet. The
receptacle is isolated from the circuitry. Its ground pin is connected to the
chassis. The contacts are closed during normal operation and open when
the unit is turned off or when a fault is detected.

-14-

Configuration

Voltage Selection

(60 Hertz Units)

The unit top is secured to the cabinet by four ball stud retainers; one at each
corner. Remove cabinet top by prying upward gently (cover pops off) in
order to perform the following adjustments.

In some cases, the side access panels may need to be removed. The
access panels are secured using screws installed through the bottom of the
cabinet.

NOTE Units rated 380-415 volt do not have a voltage selection switch.

Remove the top cover from the cabinet as described in Configuration.

The VOLTAGE SELECT toggle switch is located on the right side of the
control box. Two ranges are available: 200-208V and 220-240V. Set the
switch for the appropriate range.

Replace the top cover.

Fuses

Phase Rotation

The main fuses are 20 Amp RK5. The controller fuses are 1 Amp time delay.

Do not replace with an alternate amperage.

Single Phase Units

Remove the top cover from the cabinet.

The fuses are located on the right side of the control box.

Three Phase Units

Remove the top cover, the right access panel and the control box cover.

The fuses are located inside the control box.

Three phase units with three phase pump motors are equipped with a phase

rotation interlock. If the phasing is wrong, the controller will display PHEr and

the unit will not start.

Unplug the unit. Reverse any two power cord wires in the power cord plug.

Never remove the green ground wire.

Plug in the unit. The PHEr display should be off and the unit should start.

-15-

Pump Motor

Overload Protector

Displaying Software

Version

Three phase units with three phase pump motors have a pump motor
overload protector.

The overload protector prevents the pump motor from exposure to
excessively high current. If an overload fault occurs, due, for example, to a

heavy work load, the controller will display OL and the unit will shut down.

The overload protector will automatically reset after about two minutes. The
unit must be manually restarted.

This procedure will display the software version number on the unit’s display.
In the event the unit is not operational, the software version (and the check­sum) can also be read from the label which is on the microprocessor chip
itself.

The following chart uses an example of software version 000550.93A

Appendix

Permissible (PPM) Desirable (PPM)

Unfavorably high total ionized solids (TIS) can accelerate the rate of galvanic corrosion. These contami­nants can function as electrolytes which increase the potential for galvanic cell corrosion and lead to
localized corrosion such as pitting. Eventually, the pitting could become so extensive that leaking will
occur between the process water and facility water diminishing the System's heat transfer capability.

High water hardness (Calcium and Maganese) can also produce scaling. Scaling will inhibit heat transfer
between the process and facility side by building up a deposit layer on metal surfaces. As an example,
raw water in the United States averages 171 ppm (of NaCl). The recommended level for use in a water
system is between 0.5 to 5.0 ppm (of NaCl).

Recommendation: Initially fill the tank with distilled/deionized water. Do not use untreated tap water as
the total ionized solids level may be too high.

The desired level for long time usage is 1 to 3 MOhmcm (compensated to 25°C).

The above recommendations will reduce the electrolytic potential of the water and prevent or reduce the
galvanic corrosion observed.
