Safety instructions
General
Please read the following instructions carefully and pay particular attention to information on operating
safety and set up.
Keep these instructions at a safe place. It contains information which also refer for later maintenance
and cleaning.
The machines are intended for chemical-physical treatment of printed circuit boards.
The machines are not designed to be embedded or interconnected with other machines or systems.
They may only be used in specially equipped rooms and be operated only by qualified staff. Children
and pets are to be kept away!

Transport
Only use suitable lifting and transport equipment such as forklifts or pallet lifts. Secure the machine
against sliding / tilting.
Place of installation
The machine must be standing level and around the machine there has to be sufficient space for oper-
ation and maintenance work (approx m on all sides). To prevent the penetration of chemicals into the
ground, set up the machine either in a room with solid, waterproof and chemical resistant floor (no tiles
nor concrete!) or in a chemical resistant waterproof collection tray which can take the whole filling
volume (safety tray available as an option).
Electricity
The machine is made from certified parts according to standard practice for electrical safety. This does
not relieve the user of his duty of care when handling electrically powered devices.
The yellow-red main switch disconnects the machine from the power supply. We presuppose that the
safety fuses of the circuit and the residual current circuit are provided by the building's power supply.
After completion of the work, the main switch should always be turned off.
Before all maintenance work on the machine (filling, emptying, cleaning, etc.) turn off machine and pull
the plug.
The chemicals used in the machines often have a high electrical conductivity. Any contact of the liquid
with live parts therefore constitutes a serious threat to electrical safety. In such a case, the machine
must be immediately disconnected from the mains and the defect must be eliminated immediately and
professionally. This applies correspondingly with leaked or spilled etchant.
Water connection
After work or prolonged interruption close the cock valve of the building water supply to prevent water
damage from a possible leak in the hose.
Personal protection equipment
When handling corrosive chemicals make sure to wear protective clothing, gloves and face protection.
Observe the safety instructions of the manufacturer or the supplier.
Temperature
Switch on machine only when tanks are filled! The heater must always be sufficiently covered with li-
quid! Uncovered heaters can cause damage of machine!
The electronic thermostat is protected against breakage and short circuit of the cable to the thermal
sensor. This does not relieve the operator from the obligation, to monitor the temperature of the liquid.
Exothermic chemical reactions may under certain circumstances, which we cannot influence, cause
overheating of the etchant. The maximum operating temperature of the machine is 45 °C.
If the etchant is prepared by dissolving salts or mixing liquids, do that in any event outside of the ma -
chine! Observe the safety instructions of the chemical supplier.
If you want to use liquids which may react exothermic, take additional measures to prevent overheat-
ing. If, despite all precautions, overheating of the etchant occurs, the heater must be switched off first.
The pump however must remain switched on, so that the etchant is cooled by the circulation.
Before draining the tanks, let the heater cool down for approx. 0 min, so the heaters will not get dam-
aged.
Working safety
The machine has a lid safety switch which stops the pump circuit when opening the cover. Please
check the function regularly of the position switch.

sprint-3000-manual-e Page 7 / 12
Exhaust
An exhaust of air in the area above the machine body is recommended with regard to possible etching
fumes. The need for extraction will depend on the liquid used.
Environmental protection
Dispose used etchant according to your local regulations. Pay heed to the material safety data sheet
(MSDS) of your chemicals.
Rinsing water
The legislation generally prohibits to exceed certain maximum concentrations and quantities of copper
(and other heavy metals) in the waste water (usually 0.5 mg copper / liter of water). After etching the
boards should not be rinsed under running water and do not dispose used rinsing water into the sewer!
Operate the rinsing water only either in a closed loop rinse or treat the rinse water with a ion ex-
changer. If you do not have an in-house water treatment for the rinse water, we recommend our waste
water treatment plant IONEX or AquaPur for this task.
We recommend to use the water in the closed loop rinsing zone(s) as long as possible.
Collect used rinsing water and reuse for set up new etchant. Dispose the surplus together with the
used etchant. Neutralization of the rinsing water or even the etchant can and should be left to a special -
ist!

Commissioning
After receiving and unpacking, check the machine for possible transport dam-
ages. In case of transport damage, please inform your insurance, the transport
company and the manufacturer / supplier.
Transport to the place of installation
Only use suitable lifting and transport equipment such as forklifts or pallet lifts.
Secure the machine against sliding / tilting.
Place of installation
The machine must be standing level and around the machine there has to be suf-
ficient space for operation and maintenance work (approx m on all sides). To prevent the penetration
of chemicals into the ground, set up the machine either in a room with solid, waterproof and chemical
resistant floor (no tiles or concrete!) or in a chemical resistant waterproof collection tray which can take
the whole filling volume (safety tray available as an option).
Connections
Connect the overflow of freshwater rinse (PVC pipe D50) with your rinse water treatment. Make a con-
nection to the fresh water inlet (spout D 6). Connect inlet and outlet of the cooling (spout D 6), de-
pending on the chemical join suction of the lid (D75 / 63) to your exhaust system. Finally connect the
machine to the mains (220V / 50Hz). We presuppose an on site fuse protection of the electric circuit.

Test run
To check for leaks and function, first run the machine with water only. Fill in the
etching chamber either via the inlet ball valve or from above by opening the ex-
haustion hood and remove the cover. Fill the close loop rinse from above. In both
tanks do not exceed the minimum and maximum level, otherwise the heater or
pump may get damaged. The level mark min - max is located on the transparent
front side of the machine.
Note: The level and temperature must always be monitored by the operator.
Turn on the main power switch. The white indicator light should light up.
Turn on the transport and adjust the speed.
Check the function of etching and rinsing pump by pressing the green button be-
low pump. The spray pressure for etching zone, rinsing zone and freshwater tank
can be set by ball valves.
Turn on the heater.
Warning: The heater may be switched on only with filled tanks. If no
front panel key is pressed, the display shows the actual value of the thermo-
stats. With increasing heating time, the display must increase.
If you press the SET-button the target value is displayed in the screen. If
you additionally press the "UP" or "DOWN" button, the set point is increased
or decreased. By default, the heater is set to the target value 45 °C.
Drive a test board through the machine and check the function of the prox-
imity switch.
Open the hood - the pump must switch off (safety lid switch).
Empty the machine again via the ball drain valves.
Initial filling
Before initial filling, make sure all ball valves are closed again !! Fill the
etching zone as in the test run, but this time with the desired chemical. If ne-
cessary, use a drum pump or similar. Observe the safety instructions and Material Safety Data Sheet of
the chemical. Set up chemicals outside of the machine!
Operating
Board transport:
If you look at the machine from the front, insert the boards from the right side of the machine.
For this they are placed on the first conveyor roller and advanced to the first pair of rollers.
If there is no outlet table at the rear of the machine, you need to take the boards from the machine
manually, otherwise they will fall to the ground.
Temperature:
The temperature to be set depends on the etchant used. When etching with sodium it should be about
40 °C, with copper chloride or sulfate about 30 °C and with ferric chloride up to 45 °C.

sprint-3000-manual-e Page 10 / 12
Operating temperatures above 50 °C must be avoided. Please note that some etchant react exo -
thermically particularly at high throughput, so the etchant seems to heat itself. In this case, set the tem-
perature accordingly to a lower value. If necessary wait for cooling down of the etchant (at no-load-op-
eration) before you continue.
After work or prolonged interruption close the cock valve of the building to prevent water damage from
a possible leak in the hose.
After completion of the work, the main switch should always be turned off.
Cleaning and Maintenance:
Caution:
For service cleaning or repair work always unplug the power cord!
Before draining the tanks, let the heater cool down for approx. 0 min, so the heaters will not get dam-
aged.
Attach a short piece of hose to the ball valve of the etching tank, and put the other end into a provided
suitable container. Open the drain valve. In order to resolve any muddy residues, rinse with some extra
water through the inlet of the etching tank.
Disassembly:
. Open the exhaustion hood.
2. Remove the cover.
3. Open the nozzle bar screw thread and remove the nozzle bar.
The nozzles themselves can be easily removed by rotating
the bayonet lock. The nozzles are hold into position by the
nozzle nuts and cannot move, so no need for readjustment
when assembling again.
4. The drive units can be easily removed completely. First re-
move the upper squeeze rollers. Lift the transport unit at the
outlet side and shortly advance towards the outlet, the trans-
port unit can be easily taken from the machine.
Cleaning:
All parts beside the transparent hood can be cleaned with a mild abrasive liquid detergent. The hood
should not be treated with abrasive materials as it will lose its transparency. When using ferric chloride
as an etchant you will have good cleaning results using our stain remover RX3. The removal of dirt and
etching agent residues needs to be followed by a thorough cleaning with clean water.
Remove all sludge deposits mechanically and dispose together with the used etchant.
When you use ferric-(III)-chloride persistent dirt can also be chemically removed or at least resolved.
For this, the machine is operated instead of etchant with a 0- 5% solution of hydrochloric acid or al -
ternatively with our stain remover RX3. For more information we provide you with a separate instruc-
tion.

sprint-3000-manual-e Page 11 / 12
Rinsing the prepurified machine can also be done with a high pressure cleaner. In this case, however,
necessarily all electrical parts (console, cables, motors, etc.) must be protected against splashing wa -
ter. Attention! Etching residues and any sludge deposits must not enter the drain.
To clean the nozzles remove nozzle bars and transport system as described above.
The nozzle can be removed from the nozzle bar by turning the nut. They may only be rinsed and / or
blown out with compressed air, but not mechanically cleaned.
The filter in the etching zone must be cleaned at regular inter-
vals (every time you change the etchant).
Disposal
The disposal of the etching medium must be negotiated with
the chemical supplier.
The machine is mainly constructed from recyclable materials
and has to be disposed in a proper and environmentally
friendly manner.
