1. Loosen all Allen head set screws (A) on DNFT (B) and remove magnet housing (C). Do not remove magnet, spring or spacer
from magnet housing.
2. Remove piston enclosure plug (D) from end of divider valve where DNFT will be installed. The DNFT does not have to be
installed on the top divider valve. It may be installed on any convenient divider valve, top to bottom. (Notice:Do not install DNFT
on Lincoln divider valves with cycle indicator pins or any Dropsa divider valve less than SMX 16.)
3. Be sure O-ring or metal gasket (F) is in place on magnet housing (C). Screw magnet housing (C) into end of divider valve (E).
Torque to 15 foot pounds max.
4. Slide DNFT (B) all the way onto hex of magnet housing (C). Tighten set screws on hex of magnet housing. Torque 25 inch
pounds max.
5. The LED on the DNFT indicates each divider valve cycle. This enables operator to adjust the lubricator pump for correct cycle
time and oil consumption recommended by compressor manufacturer. If LED does not blink with compressor running or by
manually pumping oil into divider valve, the DNFT must be adjusted. Normal cycle indication is a bright strobe type blink.
6. Before adjusting DNFT, divider valve must be cycling. This can be achieved with the compressor running or by manually
pumping oil through the divider valve assembly with a hand priming pump.
7. Adjustment is made by sliding the DNFT (B) all the way on the hex of the magnet housing (C). Tighten set screws on hex of
the magnet housing to 25 inch pounds max. Check for LED blink to confirm correct adjustment. If LED does not blink with divider
valve cycling, adjust the DNFT back in 1/16" increments. Correct adjustment of the DNFT is confirmed by blinking LED.
8. All conduit and connections should be appropriate for area classification. Notice: Conduit and fittings must be supported to
avoid bending magnet housing.
9. After installing magnet assembly and pre-compressor start-up, it is absolutely necessary to purge all air from divider
block lubrication system. This can easily be accomplished with a lubrication system purge gun.
10.DNFT must be installed with correct magnet assembly for each divider valve manufacturer.
Lincoln-7/16"-20 extended nose with O- ring Dropsa
Trabon-1994 or earlier 7/16"-20 with metal crush gasket SBCO & Trabon-1995 and up 7/16"-20 with O-ring
Notice: When installing more than one DNFT, each DNFT must be wired to a separate alarm circuit
of the control panel, annunciator or PLC to simplify troubleshooting the lubrication system and DNFT.
