PROBLEM
CAUSE
ACTION STEPS
Unit is plugged in, all the lights
on the Panel are Off .
Power is not getting to
the unit.
Reset breaker or replace fuse. If power is
still not getting to the unit, call a Qualifi ed
Service Technician. Ensure that the unit is
the only device on a circuit with suffi cient
capacity.
Unit is plugged in, “READY(L)” /
“READY(H)” lights are On, Heat
light fails to come on when “ON”
button is pressed.
Power board or fuse
not functioning.
Call Uni-ram Service
Recycled solvent is not clear
1) The solvent is react-
ing chemically.
1) Lower Termperature Set Point following
Operating Procedure 4.
2) The solvent fl ow
path is dirty. One
cause is overfi lling the
distillation tank.
2) To clean the path, follow Service Pro-
cedure 2 and then recycle 3 gal of clean
solvent.
3) Orange colour due
to rust in receiving
pail.
3) Place a jar under outlet tube and capture
some solvent. If the solvent is clear, replace
the pail with a non-corrosive one.
4) Milky colour due to
presence of water.
4) Eliminate source of water in solvent.
Dirty solvent remains in Dis-
tillation Tank after recycling
Note:
1/8 Gal (500 ml) of re-
cycled solvent is expected due to
condensation.
1) Poor heat transfer
due to dirt and debris
left in the tank.
1) Clean the tank, replace the Liner Bag,
recycle with pure solvent to test. If suc-
cessfull, the problem is due to a dirty tank,
debris left in the tank or the solvent is too
contaminated. Adjust accordingly. Follow
Operating Procedures closely. If the level
of contamination is too high, recycle more
often.
2) Boiling point of
solvent is above Tem-
perature Set Point.
2) Raise the Temperature Set Point and
repeat the recycling operation.The Tem-
perature Set Point should be the BP of pure
solvent (as determined from the MSDS or
other source) plus 45°C (113°F) to allow for
contamination. If the boiing point is above
the maximum Temperature Set Point for
your model (200°C), dirty solvent cannot be
recycled in this unit.
Liner Bag sticks
Turn unit on for 5 mininutes and lift out bag
while it is still warm.
TROUBLE SHOOTING GUIDE
Carry out each action step until a solution is found. If the recommended actions do not solve the problem
call Uni-ram Service in North America or contact a qualifi ed Service Technician.
Caution: Disconnect the power supply before conducting maintenance or service.
