Introduction
TheLindberg/BlueM Mini-Mite™ TubeFurnaces areafamily of ultralightweight,
economical laboratory tubefurnaces. Thelow thermal mass Moldatherm®
insulation/heating element provides fast duty cycles, energy conservation and efficient
programming. Refer to Table1 “Lindberg/BlueM Mini-MiteTF55030 and TF55035
Series Moldatherm TubeFurnaces” for specifications.
Features and Benefits
Controlled heat-up rateeliminates thermal shock to materials.
Quick heat-up and cool-down rates.
Energy efficient Moldatherm insulation suitablefor high interior-exterior temperature
differential. Theunit is rated for amaximum operating temperatureof 1100°C.
When fitted with aprocess tubecan beused with atmospheres other than air.
Digital instrumentation for precisetemperaturesetpoint and display. Microprocessor
automatically optimizes control parameters during furnaceoperation.
Main power ON/OFF switch on control panel and act as disconnecting devicefrom
Mains Power
TypeK Thermocouple.
Intended Use
This furnaceis intended as ageneral purposelaboratory, ashing and heat treating furnace
at 1100°C for continuous (over 3 hours) or intermittent (under 3 hours) use, for light
industrial and laboratory applications only. Thefurnaceis designed for thermal technology
applications in laboratories, such as thosefound in manufacturing trades and industry,
schools, universities and biology. It is used for ageing, analysis, tempering, decomposing,
baking, annealing, hardening, soldering, oxidizing, reducing, incineration and preheating.
This tubefurnaceis suited for usewith process tubes with 25.4 mm / 1 inch diameter,
e.g. for heating under inert gas atmosphere. Pleasenotethat tubes arenot provided by
Thermo Fisher Scientific.
Non-Intended Use
This furnaceis not intended for thefollowing:
To heat up food.
For drying or heat treatment of substances which releasegases or vapors into the
atmospherethat areflammableor dangerously explosivewhen mixed with air.
This furnaceis equally unsuitablefor theheat treatment of combustibledusts and
fibrous materials.

Operating Conditions
High concentrations of sulfates, chlorides, fluorides, alkalis and V2O5can havecorrosive
effects on theceramic fiber. Contact Thermo Scientific for additional information about the
effects of specific atmospheres on furnaceperformance.
With prolonged use, hairlinecracks can develop in theinsulation materials. Theseminor
cracks will not affect thefurnace's performance. Werecommend turning off thefurnace
completely when not in use. Theheating unit is not damaged by rapid heating and cooling
cycles.

Atmosphere Systems
TheLindberg/BlueM Mini-Mitefurnaces aredesigned for usewith combustibleor inert
atmospheres when contained in aprocess tube.
WARNING : Do not usecombustiblegases directly in this furnace. Process gasses
must always becontained in aseparatetube.
CAUTION : Avoid combustibleproducts which generatetoxic or hazardous vapor or
fumes. Work should only bedonein aproperly vented environment.

Lifting and Carrying
Transport
1. For transport, do not lift thedeviceusing thedoors or components attached to the
device(e.g. control box on rear panel) as lift points.
2. Lift at thebottom sides of thefurnacewith NIOSH rated straps and/or using
appropriatenumber of personnel per local safety policies and regulations.
Location
Install thefurnacein alevel area free from vibration. To permit proper air flow, leaveat
least 12"(30.48 cm) of spaceon all sides of theunit and 12"(30.48 cm) abovetheunit.
Wiring
For detailed wiring information, refer to theFigure7 “Wiring Diagram (TF55030,
TF55035)” at theend of this manual.
CAUTION : Besureambient temperaturedoes not exceed 40°C (104°F). Ambient
abovethis level may result in damageto thecontroller. Therecommended ambient
temperatureis 17°C to 27°C (62.6°F to 80.6°F).
CAUTION : Allow at least 12"(30.48 cm) of spacebetween thefurnace, at least
12"(30.48 cm) abovethefurnaceand any combustiblesurface. This permits theheat
from thefurnacecaseto escapeso as not to createapossiblefirehazard.
WARNING : To avoid electrical shock, this furnacemust beinstalled by acompetent
electrician who ensures compatibility among furnacespecification, power sourceand
ground coderequirements.
CAUTION :
Heavy loads. Lift with care!
1. To avoid injury through physical strain, such as strain traumaand slipped discs, do
not attempt to lift thefurnacealone.
2. To avoid injury through dropped loads, wear Personal ProtectiveEquipment (PPE)
per local protocols, such as safety shoes, when lifting thefurnace.
3. To avoid crushing your fingers or hands (particularly in aclosing door) or damaging
thefurnace, do not useany other lift points than thebottom sides of thefurnace.

120 VAC Operation
TheTF55030 A-1 & TF55035 A-1 model operates on 120 VAC, 50/60 Hz, singlephase.
Each furnaceincludes a120 VAC grounded plug and cord set. Theunits arecompletely
prewired and ready for operation.
Beforeinitial start up, inspect thefurnace's wiring connections:
1. Removethecorner screws on theback panel of thefurnaceand detach theback
panel.
2. Check that thethermocoupleis securely mounted and undamaged.
3. Check thethermocouplewiring connections. Refer to Figure2 “Thermocouple”. Red
is always negative.
4. Check that all electrical connections aresecure.
Figure 2 Thermocouple
5. Replacetheback panel on thefurnaceand securewith thecorner screws.
6. Plug thelinecord into a120 VAC, 15 amp, grounded line. Thefurnacedraws
approximately 6.7 amps at 120 VAC.
CAUTION : Failureto check thermocouplewiring connections beforeinitial start up
could result in damageto thefurnace.
WARNING : Electric Shock Hazard present, appropriateElectrical PPE Required.
NOTE Only an authorized or aqualified person shall placetheprocess tubein the
devicewhilein operation. Do not placeyour hand insidetheunit whileplacing the
process tubes. If misused, theperson may comein contact with liveelectrical parts
and touching theliveparts can result in an electrical shock, burn, or electrocution. It is
always recommended to haveappropriateelectrical PPE whileoperating thedevice;
insulated TOOLS; insulating clothing; OPERATOR standing on an insulating surface
etc.

7. Highly recommended to Auto Tuneunit for application prior to use, refer to section
“Auto Tuning” .
Refer to section “Eurotherm 3216 Controller” for detailed start up steps.
WARNING : After transport and decommissioning, or storageunder humid
conditions adrying-out process must beperformed dueto hydroscopic natureof the
ceramic fiber insulation. During thedrying-out process, theequipment cannot be
assumed to meet all thesafety requirements of theIEC 61010-2-010 standard.
CAUTION : Observethefollowing precautions when operating thefurnace:
Never stand in front of an open furnace.
Wear protectiveeyeware.
Wear protectivegloves.
