GENERALITIES

This hot-pressing machine has been designed to perform intensive production while respecting the
article L 233-5 of the Labor Code, to ensure the safety of the user.
This press has been designed for an operator working in front of the machine.

USE

It is recommended to read the "instructions for use" carefully before starting any pressing operation.
The press must be used by an authorized person who has been informed of the risks that may be
caused by misuse of the equipment.
The adjustments (pneumatic, electrical and mechanical) made by our technicians in the workshop as
well as the safety devices installed on the machine must not be modified under any circumstances.
Otherwise, the company SEFA will release all responsibilities on possible problems related to the said
machine.

THIS DEVICE IS DESIGNED TO BE USED BY ONE USER

USE BY QUALIFIED PERSONNEL

a) International symbols

b) Important points

Obtain personal protective equipment E.P.I. (gloves and glasses for example)

Do not touch the hot parts of the device during use.
Do not put hands between the trays once the device is turned on.
When handling, ensure that the operator does not risk anything in terms of burns, electrocution or
other.
Perform a daily inspection of the machine before starting production.
In the area around the machine, make sure there is no one before starting.
If the machine does not work properly, switch off the power supply immediately and look for the
cause (see chapter "Maintenance" in the manual).

c) Safety features on the machine

Protections and safety devices must not be modified.

They must be reassembled in case of possible removal for maintenance.

The main security features are:

d) Emergency stop

Located on the front of the machine: if the operator activates it, it turns off the machine.

e) Security guard

Above the upper heating plate are two tab switches.
This system prevents the risk of pinching and crushing the operator.
If the system detects an obstacle, the heating plate rises, the rotation is deactivated immediately and
the press goes into safety mode.

You must press the red zone on the "Alarm" page, position the stem above one of the lower plates
and press the pedal so that the machine is functional again.

The energy mode has two settings: a long standby setting and a short standby setting.

The long standby mode puts the machine into hibernation for the time defined by the two
parameters. The temperature is then turned off, it will drop to room temperature. (No energy
consumption). If the machine is in automatic mode, it stops at the set time. The program displays the
idle page to indicate that it is paused. The brightness decreases and oscillates slightly. This mode also
allows an early start of the heating, for example before taking post. For this, it is necessary to leave the
machine under tension.

screen). The program displays the idle page to indicate that it is paused. The brightness decreases
and oscillates slightly.

Regarding the temperature, in eco mode, it is impossible to ask for a lower temperature than
the set point of the current recipe. In standby mode, it is impossible to ask for a temperature higher
than the temperature of the eco mode.

To exit the energy saving modes in progress, a touch on the screen is sufficient and
deactivates the mode (Button on "o").

A multimeter

1. REPLACEMENT OF WASTE PARTS

a) Silicone foam mat

Check that the tray is cold
Make sure the surface of the tray is clean.
Optionally use a mild solvent such as isopropyl alcohol with adequate personal protection.
Use an RTV-1 glue tube to glue the foam to the aluminum plate (NB: read the instructions on the tube
package).
The foam and the plate must be clean and dry before starting the bonding.
Spread a thin layer of glue evenly on the tray and immediately apply the foam ensuring that there is
no air bubble (Example: a spatula serrated tiler).
Let stand overnight at room temperature with low pressure and without heating.

b) Other parts

Contact your dealer to evaluate their change or repair.

2. MAINTENANCE

SEFA heat presses are virtually maintenance-free. To ensure proper operation, follow the precautions
listed below:
Do not heat objects that could damage or cut the silicone mat or damage the teflon coating of the
heating plate.
Periodically and when the plate is cold, clean the machine with a clean cloth and isopropyl alcohol
(NB: this product is flammable, use it carefully and keep it away from heat sources). provided with
adequate personal protections.
When the warming plate is hot and not used, keep it in the up position.
DAILY:
Clean the foam and the heating plate liner (cold) with a dry cloth or impregnated with degreaser.
Check the air inlet filter on the left side of the stem, purge it if there is too much condensate.
MONTHLY:
Check the lubrication of the joints.
According to the use:
Change the foam every 6 months.
