Problem:
Unit operates approximately
25 seconds, then shuts off
before all of the oil is out of
the vehicle engine.
Unit doesn’t go into the
evacuation cycle when “cycle
run” button is pushed.
(a) Oil may have too heavy
viscosity due to a heavy
weight oil or cold oil. The
engine of the vehicle should
be started and run to heat
the oil to above 70ºF. or
set the time delay switch
to hold the pump engaged
longer than the standard
25 seconds factory setting.
See time delay switch
adjustment (Figure 6).
(b) Strainer screen may be
plugged with foreign
material. Clean strainer
screen in diesel fuel (Figure
7).
(c) The FLOCS unit may be
trying to lift oil from too
low a level. 10 feet lift is
maximum. Move the FLOCS
unit closer to the vehicle oil
pan level.
(d) Hose connections may
not be right at the vehicle
pan plug. Check and
tighten hose to plug
union connection.

(a) Flow switch may be set too
high and be too sensitive
to the lower stream of oil
near the completion of
evacuation. Adjust flow
switch (Figure 5)

(b) Broad flat oil pans with
drain connection coming
out the side instead of
the bottom can cause air
to enter into the drain line
causing premature shut
off. Run a second cycle by
resetting the cycle start
button.

(c) Cold oil in the oil pan can
cause slow drain down of
the oil pan and allow the
FLOCS unit to shut off
prematurely. Start vehicle
engine and warm oil above
70ºF. before evacuating.
