JATCO Environmental Tanks
J-5000 SM-P
*INSTRUMENTATION GAS IS MANDATORY FOR SUPPLY GAS*
Listed below are a series of steps to follow if the JATCO tank fails to dump
properly.
The tank supply gas must have adequate
volume
and pressure. For best operation
use 1” pipe for the tank supply gas plumed as close to the tank as possible. Then
reduce down to the tubing connection
(C)
on the JATCO tank.
Step #1 be sure there is an adequate supply of gas pressure (
4
0-75 psi), to the inlet
connection on the float control valve. If there is enough pressure at the inlet
connection, press down on the manual dump plunger. This should cause the tank to
dump, then vent when the cycle is complete. If the JATCO tank fails to dump
manually, remove connector tubing to pilot valve
(G)
to test for pilot pressure from
float control valve
(D)
. If the float control valve is not sending pressure to pilot
valve when depressing manual dump plunger
(F)
, removal and or inspection of float
control will be necessary and proceed to step #2. If pressure is present but pilot
valve fails to operate, removal, inspection, and or replacement of the pilot valve may
be necessary.
Step #2 the side mount level controller has very few moving parts. If the valve is
not operating properly, remove and inspect travel of float arm. If no obstruction is
visually present but the float arm does not travel freely then removal of float arm is
necessary. To remove float arm carefully drive float arm retaining pin out with a
hammer and punch. Then inspect magnet and chamber for debris. If there is no
obstruction with float arm assembly or tubing connections, replacement may be
necessary.
