Dear Customer!
The RETOMAT laboratory furnaces are specially designed for precious and non-precious
alloys and model casting. The EASY controller is ideally suited for speed investment or as a
second furnace in large laboratories. The controller is easy to use enabling target
temperature setting with only a few programming steps. Temperature stays evenly in the
chamber because of the four-sided heating element and optimum chamber insulation. The
furnace door is upward opening.
Any other use or usage beyond this scope is considered unintended use. The manufacturer
shall not be responsible for any damages that may result thereby.
Prior to installation of the device operating instructions and especially the safety instructions
must be read and followed by all personnel who use this device.
After having unpacked the device, please check carefully whether transportation damages of
any kind have occurred. If that is the case, the carrier or manufacturer must be notified within
3 days. The company will not be responsible for any damages found after that.
These operating instructions must be read and followed by all personnel who use this device.
Store it at a safe place near the device. This documentation is protected by copyright.
Transmittal or reproduction of this document in whole or in part and disclosure of its contents
is not permitted. If the operation manual gets lost an extra copy can be ordered from the
manufacturer at a nominal fee.

Saftey Notes
General Safety Notes
•All equipment undergoes final inspection and testing before leaving our factory. However,
if equipment is damaged during shipping or through any other circumstances, it must not
be used in service. Please check the device regularly for damages. Damaged parts
should be replaced immediately.
•All power/air/water/gas sources should be rated for the demands of the device as listed in
the technical data sheets. Maximum ratings must not be exceeded. All VDE (Verein
Deutscher Elektro-Ingenieure) standards should be followed. Equipment should be
grounded according to standards.
•Adherence to valid regulations regarding necessary checks (e.g. according to Accident
Prevention & Insurance or electrical equipment) is exclusively taken over by the
buyer/user of this product.
•This device has been designated to be used only for its intended purpose. All other
applications must be prohibited for safety reasons as otherwise the manufacturer’s
warranty expires.
•The device should be set-up in a clean, well-ventilated room, if necessary under a hood.
•Supporting surfaces should be straight, flat and adequately stable.
•Don’t place anything on top of the machine.
•To avoid injury, appropriate protection should be worn (e.g. gloves, safety glasses, safety
shoes, hearing protection etc.)
•If the machine is defective or working improperly it must be taken out of service. In case
of further use of the machine the owner will be held responsible for any consequential
damage.
•To prevent accidents from water, fire or explosion, all power/air/water/gas sources should
be turned off after working hours and during breaks, and secured against unauthorized
access.
•When carrying out maintenance works or repairs or when opening the device always turn
off the main power switch and unplug the whole unit.
•Repairs should be carried out only by the manufacturer or by qualified and certified
personnel appointed according to chapter 7 –warranty.
•In case of leaking water out of housing or tank shut down device and call service.
•Check all hose connections for leak tightness, if necessary tighten hose clamps again.

Specific Saftey Notes
•The RETOMAT furnace may only be operated by trained staff:
−in dental laboratories for muffle burnout and other thermal treatment;
−at tool manufacturers for heat treatment of steel;
−in industry;
−at goldsmiths;
−in research laboratories.
•Heat radiation to objects or persons may not exceed 50 °C. If necessary use insulating
plates. When using the optional casting ring drawer, put the casting rings on the fire-proof
plate.
•The RETOMAT-furnaces must not be used with any inflammable, explosive or chemically
aggressive materials without any protective units or additional units.
•Don’t use any material/fluids with vapour emission, dangerous to health. Melting
substances need a protective vessel before they can be placed into the furnace.
•Don’t store any inflammable or explosive materials near the RETOMAT furnace.
•Don’t place any objects on top of the unit. If the furnace is installed in a closed
digestorium sufficient ventilation has to be assured. Please take care of sufficient
ventilation (e.g. hood installation).
•Keep a minimum distance of 1 m in front of the furnace.
Notes:
When placing casting rings into the heating chamber, please take care that the
temperature sensor which is located in the right upper edge won’t be damaged. There
must be sufficient distance between the muffles and the muffle chamber as well as the
exhaust air outlet to avoid damage to the furnace. In the event of a power failure during
operation, heating process is interrupted and not continued.
Use a ripped ceramic fleece protection as support to preserve and to extend durability of
the heating chamber. Overfilling the chamber may lead to tension cracks.
The furnace is not suitable for permanent usage in the high temperature range.
Never use the device for sintering material like e.g. zirconium oxide or the like
Check the ratings. The furnace has to be connected to a separate 16 A fused electrical
circuit.
The furnace doesn‘t need to be burnt out prior to the first usage.

10
Installation
The electrical equipment is being delivered fully installed. The sealed plug can be connected
directly to the mains supply 230 V/16 A. For installation please refer to safety notes in
chapter 2.
Installation
1. Put the RETOMAT furnace onto a stable, fireproof workplace of suitable height (minimum
width 450 mm). Use a fireproof plate for casting ring storage or use the casting ring
drawer.
2. Leave a minimum space of 50 mm around the RETOMAT furnace due to the lateral
cooling openings to enable air circulation.
3. Don’t deposit any other devices on the RETOMAT furnace to avoid local heat
accumulation.

Use of a steam ventilator or a catalyst
Screw the exhaust extraction unit with the tube connection to the back of the furnace.
Insert plug into device socket (6) of the furnace (backside).
To ensure sufficient ventilation the exhaust tube length must be short. If the required
suction power is too low, additional fans must be included into a longer tube construction.
It’s the customer’s responsibility.
Always place the catalyst or steam ventilator with the exhaust tube leading out of the
building. Contact your installer for information.
Notes:
Please note that the ceramics filter might get blocked due to strong sooting (dependent on
used material). For cleaning remove screw at chamber’s side and lift the filter upwards.
Rinse with water and reuse after drying.

13
Operation
EASY control programming:
Plug in power plug. The power switch is located on the back of the unit. The device
switch is located on the right hand side. The control panel remains under continuous
current.
The display shows the actual temperature.
To program press "Set". The display shows CI.SE.
Set the setpoint temperature directly afterwards using the arrow keys + / -. By holding
down the buttons for longer, the temperature can be set in larger increments.

14
Troubleshooting
Device doesn’t start.
a. Check domestic fuses.
b. Check the device’s fuse.
Humidity in the chamber; fuse has blown
In case of humidity problem burning out at
200 °C is recommended.
Display goes back.
After about 15 sec. without entry/selection
the display goes back to the respective
program’s basic mode.
Device doesn’t heat.
Door closed or door contact audible?
Please open and close door once again.
Insufficient exhaust fan capacity.
Use fume exhaust blower or catalyst. If
applicable pay attention to short tube length
and if necessary ask your plumber for
installation of additional fans. (Fume
exhaust is to be led out of the building).
Further errors.
Contact service.
Maintenance
•Regularly check the appliance for visible damage to the housing or the power cord.
•Clean the housing regularly with a damp cloth and use REITEL stainless steel care
spray.
