Hose ConnectionsHose Connections

Hose Connections

Hose ConnectionsHose Connections

The pump connections are located at the rear of the pump box and are
labelled PUMP INLET and PUMP OUTLET. These connections are bent
upward so the recirculating fluid will drain back into the reservoir when the
hoses are disconnected. The connections are capped with stainless steel
serrated plugs.

The pump lines have ¼" MPT for mating with standard plumbing fittings. For
your convenience two stainless steel adapters, ¼" FPT to 3/8" O.D. serrated
fitting, are provided. (To assure proper fit, they should be installed using 1½
turns of Teflon® tape around the threads.)

Flexible tubing, if used, should be of heavy wall or reinforced construction.
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.

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

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

If substantial lengths of cooling lines are required, they should be pre-filled
with bath fluid before connecting them to the unit. This will ensure that a
adequate amount of fluid will be in the bath once it is in operation.

PumpingPumping

Pumping

PumpingPumping

The pump is designed to deliver a flow of 15 liters/minute (4 gallons per
minute) at 0 feet head. To prevent external circulation, the PUMP INLET and
PUMP OUTLET lines are capped. The caps must be removed when external
circulation is required.

To properly secure the external hose connections to the unit, wrap teflon
tape around the pipe line threads before installation. Once the hose connec­tions are made, the pump must be properly plumbed to an external system.

It is important the bath is not in operation until all plumbing is complete.

If the bath is not used for external circulation, make sure the stainless steel
caps are in place prior to operating the bath.

Levelling

Inlet

Open Container

A stainless steel leveling device is available to aid circulation to an open
vessel. Contact our Sales Department for more information (see Preface,
After-sale Support).

Support the leveling device over the open container with a ringstand. Stagger
the tubes in the leveling device so one tube is submerged in the vessel fluid,
and the other tube is level with the fluid surface. Connect the deeper tube to
the PUMP OUTLET and the shorter tube to the PUMP INLET.

Adjust the flow rate using the accessory flow control valve connected to the
PUMP OUTLET, or by partially restricting the outlet tubing. When properly
adjusted, the pump inlet will draw an occasional air bubble to prevent over
flow, and the pump outlet will force fluid through the submerged tube to
prevent aeration of the vessel.

To avoid siphoning the bath work area when the unit is shut off, lift the
leveling device out of the vessel and above the level of the unit.

The bath work area has a high and low level marker to guide filling. The
markers are 1 inch horizontal slits located in the center of the stainless steel
baffle separating the work area and the pump assembly. The correct fluid
level falls between these two markers. The heating coils will be exposed and
may become damaged if the correct fluid level is not provided.

When pumping to an external system, keep extra fluid on hand to maintain

Autorefill (Optional)Autorefill (Optional)

An optional autorefill device is designed to maintain the correct level of fluid
in the reservoir. The device consists of a float switch and a solenoid valve. If
the fluid level falls, the float switch will open the solenoid valve and allow
makeup fluid to fill the reservoir. Once the fluid reaches the proper level, the
float switch will rise and the solenoid valve will close.

The plumbing connection for the autorefill device, labeled WATER INLET, is
located on the rear of the autorefill assembly. The connection is 3/8 inch OD
stainless steel. Remove the nut and install the tubing from your makeup fluid
source. Reinstall the nut and tubing on to the connection.

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

The autorefill device requires its own source of electrical power. The connec­tor for the line cord (provided with the assembly) is also located on the rear
of the autorefill device. The connector is labelled POWER.

The unit is equipped with a cooling coil located behind the stainless steel
baffle in the bath. The bath can be cooled and temperature stability improved
by circulating cold fluid through the coil. For best results, the fluid should be
at least 5°C below the temperature setpoint. The required fluid flow rate
depends on the type of fluid, the setpoint, and the desired stability.

The plumbing connections for the cooling coil are 3/8 inch OD stainless steel
tubes located on the rear of the unit. These connections will accept 3/8 inch or

5

/16 inch ID tubing. Tubing is available from Thermo NESLAB.

Connect the COOLING COIL IN tube to the cold fluid source. Connect the
COOLING COIL OUT tube to the cold fluid return (or drain if tap water is
being used).

EX-221 and EX-511 units are equipped with a boost heater. The boost
heater is designed to provide additional heat to the unit.

To start the heater press the BOOST HEAT switch, located on the front of
the temperature controller, to the ON position. Even though the switch
automatically returns to the OFF position, the boost heater will start to
function. (You can verify this by observing the fluid temperature rising.) The
boost heater automatically ceases operation when the setpoint is reached.

Low Liquid Level SafetyLow Liquid Level Safety

Low Liquid Level Safety

Low Liquid Level SafetyLow Liquid Level Safety

To protect your application, the adjustable High Temperature/Low Liquid
Level Safety (HIGH TEMP/LOW LEVEL) ensures the heater will not exceed
temperatures which can cause serious damage to your unit. A single tem­perature sensor, located on the heater coils in the bath, monitors both condi­tions. A High Temperature/Low Liquid Level fault occurs when the tempera­ture of the sensor exceeds the set temperature limit.

In the event of a fault, the unit will shut down. The cause of the fault must be
identified and corrected before the unit can be restarted.

The safety on single heater systems is not preset and must be adjusted
during initial installation.

Units with a boost heater have an additional nonadjustable safety located
behind the main safety. It has a red reset button but no adjustment knob.

To set the safety, locate the HIGH TEMP/LOW LEVEL SAFETY adjustment
dial on the right side of the pump box. Turn the dial fully clockwise and press
the red RESET switch. The RESET switch is located next to the adjustment
dial. NOTE: For units without a reset switch turn the I/O switch off then back on.

Start the unit. Adjust the setpoint for a few degrees higher than the highest
desired fluid temperature and allow the bath to stabilize at the temperature
setpoint. Turn the HIGH TEMP/LOW LEVEL SAFETY dial counterclockwise
until you hear a click and the unit shuts down. The red FAULT LED on the
temperature controller will light to indicate a fault has occurred.

Cool the bath and then, without moving the adjustment dial, press the red
RESET switch or turn the I/O switch off then back on.

Plaats het apparaat op een tafel of werkbank.
Omgevingstemperaturen moeten liggen tussen de
+10°C en +27°C.

Let erop dat de netspanning gelijk is aan het
aangegeven voltage, +/- 10%.

De slangaansluitingen zijn bevestigd aan de
achterkant van het apparaat en zijn voorzien van
de labels PUMP INLET en PUMP OUTLET. Deze
aansluitingen zijn 1/4 inch MPT. Verwijder de
pluggen indien externe circulatie gewenst is.
Bevestig de PUMP OUTLET aan de ingang van
uw applicatie. Bevestig de PUMP INLET aan de
uitgang van uw applicatie.

Vul nu het reservoir tot het niveau tussen de
horizontale strepen op de roestvrij stalen
scheidingsplaat, die de werkruimte van het
pompgedeelte scheidt.

Gebruik nooit brandbare of andere
koelvloeistoffen, die het toestel kunnen aantasten.
Kraanwater wordt in het algemeen aanbevolen
wanneer u bij temperaturen werkt van +8°C tot
+80°C. Boven de + 80C. zal de gebruiker
verantwoordelijk zijn voor de benodigde
vloeistoffen. Indien men boven de 115°C. werkt,
gelieve nooit puur ethylene glycol als badvloeistof
te gebruiken.

Wanneer u wilt pompen naar een extern systeem,
dient u altijd extra vloeistof achter de hand te
houden om met juiste vloeistofniveau’s zowel in
het interne als het externe gedeelte van het
systeem, te handhaven.

Gebruik het apparaat nooit wanneer het reservoir
leeg is.

Operationeel gebruik

Alvorens het apparaat in gebruik te nemen, dient
u eerst alle elektrische- en slangaansluitingen te
controleren. Tevens dient u te controleren of het

systeem gevuld is met vloeistof.

220 Volt apparaten hebben een z.g. “circuit
breaker” aan de achterkant van het apparaat.
Controleer of deze in werking is gesteld. Om het
apparaat te starten, gelieve de I/O knop aan de
zijkant van het apparaat te draaien naar de I
positie. Het lampje zal oplichten als indicatie dat
het systeem in werking is gesteld. Om het

O positie te draaien.

Het “HEAT LED” duidt de actuele status van het
verwarmings-element aan. Het zal oplichten
indien het verwarmingselement in werking is
gesteld. Als de ingestelde temperatuur de set­point heeft bereikt, zal de LED aan en uit gaan om
het proces van de heater aan te duiden.

Analog Controller Temperature Adjustment

Om de temperatuur set-point aan te passen, draai
de SETPOINT ADJUST knop aan de voorkant
van het apparaat naar de gewenste temperatuur.

Digital Controller Temperature Adjustment

Om de temperatuur set-point af te kunnen lezen,
houdt u de DISPLAY knop ingedrukt. Om de
temperatuur set-point aan te passen, houdt u de
DISPLAY knop ingedrukt en draait u de set-point
set point knop, totdat de gewenste temperatuur
set-point af te lezen is van de display. Als de set­point is aangepast, kunt u de DISPLAY knop weer
loslaten. De display zal nu de temperatuur
weergeven van de vloeistof in het reservoir.

Periodiek Onderhoud

Het reservoir dient regelmatig gecontroleerd te
worden. Indien reiniging noodzakelijk is, zal het
reservoir schoongespoeld moeten worden met
een vloeistof, welke verenigbaar is met het
systeem en de koelvloeistof.
