INTRODUCTION
Thank you for selecting this product from the large range of products manufactured in
Australia by Thermoline Scientific.
The materials incorporated in this design have been carefully selected for their
durability, technical performance, and practicability, the resultant product is one we
are proud of.
THE MANUAL
Please familiarise yourself with the information contained in this manual before using
the equipment.
Ensure that the manual is kept safe but accessible for current and future operators to
refer to.
UNPACKING
Remove the equipment from the packing material, check that it is complete.
Assemble the components and inspect for damage.
Retain the packaging materials until the equipment has been thoroughly tested.
Notify the detail of any damage without delay to your supplier, or Thermoline
Scientific.
LOCATION
Place the equipment in a well-ventilated area ensure that it is mounted on a
fabricated bridge or supported by the optional bath to heater bracket/clamp. Confirm
that the power supply is suitable for this equipment. Refer to the equipment rating
plate for details. To control temperature effectively, the equipment should be located
in a stable ambient.
WARNING: Ensure that the electrical
outlet is earthed and is of the correct
voltage and is capable of carrying the
stated current load.
INTENDED USE
This equipment is used to provide a convenient method of maintaining the
temperature of a bath to 100°C whilst circulating the water to minimise temporal
variation.

CAUTION: The range of heater
circulators described here are not to be
used in conjunction with oil as Pyrolysis
(Chemical Decomposition by Heat) will
occur.
WARNING: Do not use flammable
solvents or combustible materials as fire
or explosion may occur. This equipment
uses components which may be a
source of ignition.
FUNCTION
To provide an accurate controlled temperature between +30°C to +100°C.
Model TU-1: ambient +5° to +100°C.
PRINCIPLE OF OPERATION
The analogue range of Heater Circulators are designed to be compact, light and
efficient heater circulators of water. They are ideally suited to Laboratory Bath
applications where minimal spacial variation is tolerated.
The analogue controller, and long shaft (240 Volt) electric motor are located within
the controls enclosure. Below is suspended, the circulating pump housing, heating
element and sensor.
The desired operating temperature is set at the control. A signal from the sensor is
monitored at the controller. The resultant output switches power to the heating
element.
Energy from the element gently heats the water, the amount of energy is determined
by the sensor.
The circulating pump runs continuously maintaining close temporal uniformity
throughout the bath.
The heater circulator may be supported on a fabricated bridge (standard with each
Thermoline Scientific circulating water bath) or from an optional bath to heater
bracket/clamp.
Note: When working at temperatures above 60°C a suitable bath cover (lid) should
be used to maintain the operating environment and minimise energy loss.
PERFORMANCE
The operating range for this equipment is +30°C to +100°C Model TU-1 is ambient
+5°C to +100°C, Temporal Stability 0.5°C.
MAXIMUM TEMPERATURE
For this product is +100°C.

C-TICK
The equipment referred to here complies with requirement of AS/NZS 1044:1995
electromagnetic interference (EMI).
INSTALLATION (Refer to Unpacking Page 2)
Place the equipment in your bath in a well-ventilated area, on a firm level surface and
ensure that a suitable power supply is available.
WARNING: Ensure that the electrical
outlet is earthed and is of the correct
voltage and is capable of carrying the
equipment stated current load (AMPS).
The models TU-1 is suitable for bath use only.
MAINTENANCE
The Thermoline Scientific range of heater circulators requires no routine
maintenance other than normal levels of cleanliness.
The external surface of the control enclosure is powder coated aluminium steel. It
may be wiped clean using a damp, soft cloth. The element and pump housing, refer
to following note).
Note: Stainless steel is under most conditions extremely resistant to corrosion. This
is in part due to the addition of chromium and nickel to the steel and the formation of
a durable chromium oxide at the surface during the manufacturing process. There
are several chemicals which will attack the surface of stainless steel, plus the lack of
oxygen at the surface will cause rusting, corrosion and pitting. Distilled/Deionised
water is particularly corrosive. To minimise, maintain a Neutral pH (7-9).
Always have in place a program of regular cleaning using a soft damp cloth with a
mild solution of soap and water and allow to dry.

EXPLANATION OF CONTROLS
The controls are located in a control enclosure above the heating element and pump
housing assembly.
MAIN SWITCH
This is a combination power switch and circuit breaker, when pressed this switch
allows power to be supplied to the controls and the pump circulating motor.
Incorporated in the face of the switch is a ’MAINS ON’ indicating light.
CAUTION: The equipment is fitted with a combination circuit
breaker, mains switch. If the circuit breaker continues to trip, it
may indicate an electrical fault exists. Switch Off the power and
consult a qualified technician.
The temperature range is +30°C to +100°C (Ambient +5°C) Model TU-1. The desired
operating temperature is set at the control knob against the scale which is graduated
at 2°C increments. The control is factory calibrated.
Maximum recommended temperature is 100°C (Equipment Dependant).
ELECTRICAL - POWER LEAD
A removable mains power lead with a three pin plug and right angle female IEC
socket is supplied for connection between the male IEC socket located at the rear of
the incubator (top left side) and a ten (10) Amp General Purpose Outlet (G.P.O.)
Caution: Should the circuit breaker continue to
trip, switch off the power and consult a qualified
technician.

OPERATION
WARNING: 1. To avoid injury do not use flammable solvents with this
equipment, as fire or explosion may result. This equipment contains
components that may ignite such materials.
WARNING: 2. Do not introduce oil into this bath as the concentrated
heat energy may result in Pyrolysis (Chemical Decomposition by
Heat).
OPERATING THE HEATER CIRCULATOR
1) Ensure that the heater circulator is located as previously described, refer to
the index, LOCATION, Page 2.
2) Fill the bath with cool *clean water to a minimum of 80mm above the element.
* - Refer to Page 4 section Maintenance for details on water condition and
compatibility with stainless steel.
Warning: This equipment contains components rated
at 240V AC. Ensure that it is secure and the control
enclosure will not contact water.
3) Connect the electrical lead into a 10 Amp 240 Volt 50Hz GPO (General
Purpose Outlet).
4) Select the desired operating temperature at the control knob
Caution: Contact with hot fluid/vapours, bath surfaces
or product under evaluation may result in personal
injury, ensure appropriate protective equipment and
procedures are applied at all times.
5) Turn the power outlet (GPO) and the heater circulator switch to the ON
position and allow sufficient time for the water to stabilise.
6) When the water has stabilised, check the temperature with a mercury in glass
thermometer (or similar) and adjust the control knob setting if necessary.
7) Optional – Support Bracket – TUSB
a) The bracket is attached at the rear of the heater control case using the
bolt and washers supplied.
b) With the bracket attached, position the heater circulator over the edge
of the bath, with the flat face of the bracket to the inside of the bath.
Slowly tighten the screwed adjuster until the circular pad is held firm
against the outside of the bath.
