ACTION STEPS
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.
Call Uni-ram Service
1) Run SETUP and lower the Termperature
Set Point.
2) To clean the path, follow Service Pro-
cedure 2 and then recycle 3 gal of clean
solvent.
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) Eliminate source of water in solvent.
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) Run SETUP, raise the Temperature Set
Point and repeat the recycling operation.
The Temperature 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 (either 200°C or
240°C), dirty solvent cannot be recycled in
this unit.
3) Run SETUP and over-ride the auto
SHUT-OFF. Select a time period long
enough to recycle the solvent. The heater
will stay on for this duration. Repeat the
recycling operation.
Turn unit on for 5 mininutes and lift out bag
while it is still warm.
