FRED 8
The programmable spraying system FRED 8 is a tank and pump unit to be carried on one’s
shoulders, in order to leave the operator free to move while spraying preset liquid drug dos-
es.
The structure is divided in two parts. A semi-transparent 8 lt tank at the top, which allows to
check the contents of the tank at a glance while the pump, the battery, the electronic controls,
the main switch and the relevant voltage lamp are located at the bottom.
The device can be carried on one’s shoulders thanks to a pair of adjustable belts. The hose
to feed the spraying nozzle is located on the right hand side and comes complete with oper-
ating control.
The lithium-ion battery is located in a closed compartment with snap-on door. To recharge it
simply plug the battery charger pin into the receptacle next to the switch.
A warning lamp on the charger will be lit red while recharging and turn green once the charge
is complete.
Operation
The operation is easy. After filling the tank with the necessary liquid, the system can be
switched on by acting on the switch on the left hand side. The machine becomes operative
only by using the BLE (BlueTooth Low Energy) connection, used for programming.
Therefore the FRED_8.2 application shall be activated on an Android smartphone near the
sprayer. With no BlueTooth connection the appliance will remain in standby (idle).
Once connection is established, the appliance operates in the manual mode. The pump is
started by pressing the trigger on the spraying nozzle. The pump will be active until the con-
trol is released. This manual condition is useful in the early stages, to fill the product in and at
the end for cleaning and washing the device with detergent or water.
As soon as the appliance is switched to the automatic mode, a preset quantity of product can
be sprayed. By pressing the control without releasing it, the pump will carry out the pro-
grammed number of rotations and supply the exact quantity of liquid to the nozzle. If the con-
trol is revealed before the required number of rotations the spraying operation will stop.
After programming the required quantity and switching the appliance to the automatic mode,
a connection is no longer required. The device can be prepared by a skilled operator and
then delivered to workers who do not have a phone (however a connection is required to take
the appliance back to manual mode).

Application
The FRED_8.2 app can be downloaded from https://valerytech.net/ in .APK format and be
installed directly (the appliance only uses the Bluetooth low energy version and no other de-
vice or sensor). Do not forget to allow installation in your phone even if it is not Google certi-
fied.
Upon startup, the app displays the company logo
and an image of FRED 8, with a line of text that ex-
plains being automatically searching for the device to
be combined with (screenshots on the right).
Should the application not find the appliance to be
combined with, a message would appear on screen
to point out the situation followed by a goodbye
message (screenshots below).
We remind
you that the
application
must be closed to try to get connected and then
launched again. After switching FRED 8.2 on, be-
fore getting connected, a few seconds should elapse
while the card carries out the preliminary operations
required.
While starting up, the card displays a light sequence
through the multicolor led at the bottom rear of the
device. The three colors (blue, green and red) flash one at a time with a 500
ms dark interval.
When the application detects the right device to connect to (automatically),
the first line of the display will read a number (“1” in the example on the right).
This is the code chosen from a list of Bluetooth devices found during the pre-
vious research step.
After a short while, the phone will display the page for FRED 8 setup. As al-
ready mentioned, after connecting with the phone, the appliance becomes
live. Therefore by pressing the lever on the spraying nozzle the pump will be
activated (and, of course, the liquid in the tank, if any, will be sprayed).

The gear pump can stand running dry for a limited time span. We recommend not to let the
pump run dry for a long time (max. 60 to 90 seconds).
The operation page is displayed as shown in the image in the next page. There are two but-
tons to determine the operating mode of the sprayer and an area below them to set the quan-
tity to be sprayed.
The lowest line contains some pieces of information: the battery voltage
on the left and the set count on the right.
The relation between cc and revs is calculated by the system automati-
cally according to the pump geometry. We point out that the actual quan-
tity being sprayed also depends on other parameters, especially on the
viscosity of the fluid being used. Therefore a check before starting will
always be useful.
For instance, a test carried out by activating the system ten or twenty
times will allow to detect the exact numerical value to set in
order to spray the required quantity.
The application limits the minimum and maximum acceptable
values to a range of 12 to 35 cc. When the limits are being exceeded, a warning
is issued and the set value will be the one closest to the limit.
Once the required volume has been set the data are sent to the appliance by se-
lecting “SEND” Press the bottom right area in the bottom line to learn how many
pulses the sprayer is producing.
Both the battery voltage and the number of pulses are ob-
tained upon request only, in order to limit energy consump-
tion.
Press the “-“ and “+” keys located respectively on the left and
on the right of the central numerical value, if you need to change the cc
value. Then press the button to send the new value to the appliance.
As already said, press the value of the new data to check the, by acti-
vating the update of the number of pulses. In the same way press it to
check the battery voltage value in order to update it.
The system checks the voltage not to work with too low a voltage. This
would damage the battery and reduce its operating life. At the limit value,
the motor would stop and the outside led would flash. However we recommend recharging it
after use.

After filling the tank with liquid, in the manual mode,
switch to the programmed operation by pressing
“AUT”. The new conditions are displayed by the button
color changing (see images).
The machine produces the quantity of product preset
automatically whenever the control lever on the spraying nozzle is pressed (without releasing it
during the whole cycle).
The led that appears on the outside gives the following information: first of all it comes on
steadily when the system switches to the automatic mode. The same color is also used when
the led flashes in quick sequence to show the state of the rotation pulse counter of the pump.
A 200 ms flashing cycle shows too low a voltage of the battery, while a 500 ms flashing cycle
would indicate a pump timeout (the motor is on but the sensor controlling its motion has no
pulses to operate). In both cases the motor is deactivated.
Standard procedure
The easy operation of the FRED 8 appliance can be summarized as follows:
§ Fill the tank with liquid
§ Switch the system on
§ Launch the FRED 8.2 application
§ Press the control lever to load the pump and the spraying nozzle
§ Set the volume to spray and send it to the appliance
§ Switch to automatic mode
§ ------ operate -------
§ Once the operation is over, switch the device back to manual mode
§ If needed, recover the liquid remaining in the tank
§ Fill the tank with water and/or detergent
§ Flux both pump and nozzle to clean them thoroughly
§ Switch the device and the application off
§ Recharge the battery
Starting procedure
When you start using the device for the first time, should you use liquids with a different vis-
cosity and need to change the needles, we recommend a trial test to combine with precision
the values set and the quantity actually being sprayed by the system.

Carry out the test with clean needles, clean nozzle and clean device. After filling the tank with
liquid, we recommend at least ten spraying cycles before checking the total volume being
sprayed in order to determine the exact ratio between set value and actual volume of liquid
being sprayed.
In fact the pump always carried out the number of rotations you have programmed, while the
sprayed quantity also depends on the liquid viscosity and the load losses of the nozzle.
Notes
Always set the required value on the device (whenever you switch it on, the default setting is
fixed and could be different from the requirements).
During the operation always check the needle is not clogged, which could modify both the
spraying time and sprayed quantity alike.
Clean the appliance thoroughly after each use.
Always cap all the needles after use and after cleaning.
The lithium ion batteries do not have the unpleasant “memory effect” that plagued NI-Cd bat-
teries. Therefore we recommend you charge them after each operating cycle. This will extend
the battery life and avoid being interrupted while working because of voltage loss.
When the batteries are fully charged (charger lamp green) we recommend you unplug the
battery charger even if there would be no overload risks.
