For optimum performance of the carburetion control, a gas pressure regulator must be installed upstream of the
Tecjet 52 valve. We recommend that the volume between both devices be minimized by placing a regulator
close to the engine and with a straight fitting of a minimum length equal to 5 times the diameter of the pipe
linking the pressure regulator to the Tecjet52. Under stable operation, the input pressure to the Tecjet 52 valve
should not fluctuate in more than +/- 2 mbar.
With the engine running at full power, the position of the Tecjet52 valve must lie anywhere between 20 and 85%
of its total travel. In the event it is near any of the said limits, then, if the equipment allows and the input
pressure and pressure drop requirements are fulfilled, it will be necessary to adjust the pressure regulator so as
to work with the valve in the recommended position.

3. WORKING TEMPERATURES

Room temperatures for Tecjet52 operation:
Tecjet52 gas temperature range:
Kohler recommended gas temperature in operation:+10 ºC to + 40 ºC

4. GAS FILTER

To prevent damage, a 1μm or thinner mesh filter must be installed at the Tecjet gas intake.
With regard to the contaminants contents, gases must also meet the specifications set out in Product
Information IC-G-D-30-001e,
IC-G-D-30-018e and IC-G-D-30-038e.
