10. Settings and Adjustments
The Teknospeed system is preset at the factory for operation. You can modify the pressure value
to suit the actual system requirements; proceed as follows:
The two pumps must be set separately (one at a time) to the same pressure value by powering
only the one being set and switching off the other one.
Increasing the pressure value
Make sure that the system is pressurized, no user is open and the pump is off. Unscrew the plug
that protects the adjusting screw.
Turn the adjusting screw slowly to the right using a screwdriver. Use the slotted blade screwdriver
(2.5 mm) provided with the TKS system.
The adjusting screw (potentiometer) has a limited
travel, less than one turn , between the minimum value (0 bar) and the maximum value (10 bar).
Do not force it beyond the limits as you could damage the adjusting screw, and do not insert any
objects, for any reason, in the TKS inverter. The pump will start.
Read the pressure value on the gauge and keep turning the adjusting screw until the gauge pointer
reaches the desired value.
Make sure that the pressure has stabilized at the desired value.
If necessary, make slight adjustments by turning the adjusting screw to the right or left. If you need
to lower the pressure setting, we recommend that you open a user partially (see next section
“Lowering the pressure value”).
Make sure that the new value you have selected is within the head range specified in the TKS
system’s rating plate.
The pump stops after approx. 60 seconds. The switch-off pressure may be slightly higher than the
desired value (see chapter 6.4.1).
Lowering the pressure value
Make sure that the system is pressurized, no user is open and the pump is off.
Unscrew the plug that protects the adjusting screw.
Make sure that the on-off valve located on the pump’s delivery side is open.
Open a user or the test tap (chapter 6.1) partially, allowing the pressure to drop slowly.
The pump will start.
Turn the adjusting screw slowly to the left using a screwdriver.
Use the slotted blade screwdriver (2.5 mm) provided with the TKS system. The adjusting screw
has a limited travel, less than one turn, between the minimum value (0 bar) and the maximum
value (10 bar). Do not force it beyond the limits as you could damage the adjusting screw.
Read the pressure value on the gauge and keep turning the adjusting screw until the gauge pointer
reaches the desired value.
Make sure that the pressure has stabilized at the desired value.
If necessary, make small adjustments by turning the adjusting screw to the right or left.
Make sure that the new value you have selected is within the head range specified in the TKS
system’s rating plate.
The pump stops after approx. 60 seconds. The switch-off pressure may be slightly higher than the
desired value (see chapter 6.4.1).
