Solvents are heavier than air and accumulate near the fl oor.
The area or room where the solvent recycler is located must have suffi cient natural or artifi cial ventilation
to prevent the accumulation of solvent vapor air mixtures. If a ventilator is used it must be of class 1, divi
sion 1 and used in a way to safely exhaust fumes. Check the arrangement with local authorities.
Fire Extinguisher:
A fi re extinguisher (dry chemical type) of class BC or ABC must be kept nearby.
SOLVENT REQUIREMENTS
2) Comply with the instructions in the section: CAUTIONS AND WARNINGS.
3)Ensure that the safety lid and door freely opens fully and a container for receiving the distilled solvent
can freely move in and out of the cabinet. The unit must be in a location where people or equipment can-
not disturb the cable or connection. The cord must be connected directly to the main power supply; an
extension cord cannot be used.
4) Connect the unit to a dedicated, single phase 220/240V, 30 Amp branch circuit.
SOLVENT REQUIREMENTS
This unit recycles fl ammable solvents and combustible solvents. Flammable solvents include lacquer thin-
ner, paint thinner, acetone and other paint diluents. Flammable Solvents have a fl ash point below 38.7°C
(100°F). These solvents are commonly used in the industry as a cleaning solvent, or as a paint diluent.
Dirty solvent to be distilled must meet each requirement described below. The MSDS, material solvent
data sheet, provides data on the properties of the virgin solvent.
1) The BP (Boiling Point) of the dirty solvent must be less than 200°C (392°F) for the URS2000 Series
and 240°C (464°F) for the URS2000PW and the RI 80. BP increases with greater contamination.
2) The auto-ignition temperature of the solvent to be distilled must be higher than 250°C (482°F) for safe
operation. Do not recycle Nitrocellulose. The auto ignition temperature is 135°C (275°F).
Notes:
• Recycle recently contaminated solvent only. Standing solvent can become acidic over time.
• To avoid “FISH EYE” problems, do not recycle both paint dilutents and parts washer solvent in the
same unit.
Waste Residue
The waste residue of some paints will remain moist after recycling due to the composition of the paint
itself. A dry waste residue is not guaranteed.
Defi nitions
Flash Point:
The lowest temperature at which the vapor of a solvent can be made to ignite momentarily in air.
Auto-ignition Temperature (often referred to as “ignition Temperature” or “Ignition Point”):
The temperature at which solvent ignites by itself.

2) Install the Receiving Container, the Transfer Hoses and the air Supply
Receiving Container
• A 20 US Gal (80 liter) container must be used to receive the distilled solvent. Make sure the Solvent
Outlet Tube is properly inserted into the top opening of the Receiving Container by at least 1 inch (2.5
cm).
• When placing the Solvent Receiving Container, make sure the alligator clamp of the Grounding Strap
is fi rmly connected to the exposed metal surface of the container.
Air Supply
• These models are equipped with an air operated Dual Diaphragm pump and require a supply of clean,
dry air of at least 85 PSI (6 kg/cm2). A pre-set Pressure Regulator is included.
• Connect the air supply to the Air Inlet Fitting (1/4” NPT Female Threads) located at the right side of the
unit. Make sure that there are no leakages at the connection. Make sure that the air is free of dust, rust
and other contaminants. Use a Moisture Filter (not supplied), if necessary.
Hose Connections
• Place the drum/container with the dirty solvent to be distilled close to the unit.
• Connect the Solvent In Hose to the Solvent In port of the unit and insert the other end (with the Tank
Filler Suction Pipe) into the drum/container.
• Connect the alligator clamp at the end of the Ground Strap to the container with dirty solvent.
• Place the drum/container for the clean solvent close to the unit.
• Connect the Solvent Out Hose to the Solvent Out port of the unit and insert the other end with the
Outlet Tube into the drum/container. The Outlet Tube must extend below the rim of the pail to prevent
solvent spillage.
• If the pail is metal, connect the alligator clamp of the Ground wire to the rim of the drum/container.
3) Transfer Solvent to the Recycler Tank
• Turn the Handle of the Filler Valve counter-clockwise to open the fi lling passage.
• Turn the Filler Timer Knob clockwise fully. After a few seconds, dirty solvent will start fl owing into the
Distillation Tank.
• Fill to 3” below retainer ring. After the fi lling process has been completed, turn the Handle of the
Filler Valve clockwise and close the Tank Lid. Make sure that the sealing area around the top of the
Tank is clean and damage free.
• Close the Distillation Tank Lid and secure with Lid Clamp. Make sure that the Lid is fi rmly seated to
avoid leakage.
• Close the Safety Cover.
4) Check distillation conditions and change, if necessary, using SETUP MODE.
Estimate Boiling Point
Add 40°C (100°F) to the boiling point of the pure solvent as shown on the MSDS (Material Safety Data
Sheet) or another reliable source.
Recycle more often
The boiling point of the waste solvent mixture increases as it gets dirtier. To reduce the boiling point,
recycle more often.
Minimize Temperature Set Point
After recycling there will be a small amount of solvent, about 1/8 US gal (500 ml), remaining in the distil-
lation tank due to condensation. Select the lowest Temperature Set Point that recycles the solvent to this
level.
If all the settings are acceptable, press START to begin distillation.
To change settings, enter Setup Mode

MANUAL - SOLVENT RECYCLERS - URS1600 SERIES, URS2000 SERIES & RI 80 Rev 2019-05
Note:
If your model is URS2000SSP follow the instructions below. Otherwise skip this section and continue to section 6,
Finish Recycling.
Set Up:
Fill receiving container with 5 L of clean solvent. This level of solvent is needed to create a vacuum at the venturi.
This step is done once, before the fi rst recycling.
The set up temperature in degrees centigrade (C) is the boiling point of the solvent plus 40 degrees.
With vacuum, the set up temperature is the boiling point of the solvent plus 10 degrees C and not more than 200
degrees C. The power percentage is set to 80 % if the voltage is above 220 V. The power percentage is set to 90 %
if the voltage is below 220 V.
Operating Procedures:
After the operator presses “ON” to turn on the solvent recycler, turn on the vacuum toggle switch. This step will start
the vacuum pump.
Once the heat light has gone off , the recycler has gone into cooling, turn off the vacuum toggle switch. This step
will stop the vacuum pump. If the operator forgets to turn off the toggle switch the clean recycled solvent from the
receiving pail will return to the distillation tank due to a higher vacuum.
5) Recycling
On fi rst power up and on RESET, the Display Panel shows the Software Version, then:
“READY S.P. = XXX°C” (S.P. = SET POINT). When Setup is complete and START has been pressed,
the “HEAT” light comes on and the recyling process begins. During the boiling phase, 3 temperatures
will alternate on the Display: “SET-PT”, “TANK” and “VAPOR EX.” When the boiling phase is complete,
“COOLING” will be displayed. Note: the fan may still be running; this is normal as it continues to run until
the temperatue drops below 50°C. To cancel the cycle, press the “STOP” key.
If your model is URS2000SSP, vacuum version, see the note at the bottom of the page.
6) Finish Recycling CAUTION: DO NOT OPEN LID UNTIL COOLING IS COMPLETE
The clean, recycled solvent is available for use when the display shows “READY S.P. = XXX°C”. After the
clean solvent is transferred, the unit will be ready for another cycle.
7) Transfer Clean Solvent
a) For models without the Solvent Transfer System: remove the pail and replace with an empty one.
b) For models with the Solvent Transfer System: turn the Transfer Timer knob clockwise fully. The clean
solvent will fl ow out of the Solvent Receiving Pail into either a free-standing, external container or the
Clean Solvent Pail of a Spray Gun Cleaner. The transfer will stop when the timer runs out.
8) Remove Debris:
Remove the Retainer Ring and slowly pull the Liner Bag containing the debris out of the distillation tank in
a way that the Liner Bag does not break. Dispose of the debris in accordance with local regulations.

10
MANUAL - SOLVENT RECYCLERS - URS1600 SERIES, URS2000 SERIES & RI 80 Rev 2019-05
NOTE: If the bag sticks to the bottom of the tank, turn the recycler on for 5 minutes to loosen the bag from
the bottom of the tank, then lift the bag out while the bag is warm.
9) Clean Distillation Tank and Lid Surface
Distillation Tank:
Wipe inside the Tank with a cloth.
Remove any remaining debris from the Distillation Tank using if necessary, plastic or wooden tools (not
supplied). Do not clean with abrasive or hard metal instruments that can damage the tank. The warranty
does not cover such damage.
Note: There will be about 1/8 Gal (500 ml) of solvent remaining in the Distillation Tank after recycling due
to condensation. This solvent, If left in the tank, can cause corrosion. Dirt and debris left in the tank can
prevent full heat from reaching the dirty solvent during recycling.
Caution: Acidic or chlorinated solvents typically cause corrosion on an aluminum tank. It appears as
black pitting spots on the tank. Excessive pitting leads to an unsafe condition of holes in the walls of the
tank and solvent leakage. Inspect your tank after each batch. If there is excessive pitting, call a Service
Technician and replace the tank with a corrosive resistant, stainless steel one.
Lid Surface:
Use a cloth. Dry and clean the lid and the top of tank where the the Lid Gasket sits to extend the life of the
Lid Gasket and prevent leakage. Avoid rotating the lid during cleaning. The lid gasket is a wear item.
10) Install a new Liner Bag
Lift Recycler Safety Cover and Tank Lid fully; lids will stay in the open position.
a) Install the Liner Bag so that the bottom of the Bag sits fl at on the bottom of the Distillation Tank as
shown.
b) With thumb and index fi nger, squeeze the Retainer Ring and insert into inside of the Liner Bag. Let go
and make sure it fi ts securely in the groove.
d) Fold the fl ap of the liner bag over the retainer ring.
Caution: Ensure that the bag material does not block the Vapor Outlet.
11) Inspect Lid Gasket, Remove and Replace if necessary as required
Inspect the Lid Gasket for shrinking, hardness and cuts. The Lid Gasket is a wear item as it is exposed to
high temperature and solvent vapor during distillation. Damage to the lid gasket will cause solvent to leak.
To remove, open the Safety Cover and Tank Lid. Lift out the old gasket by hand and clean the cavity with
a cloth. To Install, place the new gasket in the cavity, rub solvent or soapy water on the gasket to make
insertion easier. Press the gasket fi rmly into the cavity all around.
Note: Keep a spare in stock. One extra is included with the unit.
NOTE: This is a schematic drawing only; not all components are exactly as shown.

THEORY OF OPERATION - DISTILLATION PROCESS
Waste solvent consists of the original solvent plus liquid and solid materials picked up during use of the
solvent. Recycling separates the original solvent from the waste materials. During the recycling process,
the distillation tank fi lls with dirty solvent and the heating element heats the mixture. The solvent mixture
boils and the vapour passes through a cooling condenser where purifi ed, clean solvent, ready for use
condenses out. Waste materials in the dirty solvent boil at a temperature substantially above the Tem-
perature Set Point so they remain in the distillation tank for disposal.

Call Uni-ram Service
Recycled solvent is not clear 1) The solvent is react-
ing chemically.
1) Run SETUP and lower the Termperature
Set Point.
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) 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) The Auto Shut Off
system is shutting the
unit off too soon.
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.
Liner Bag sticks Turn unit on for 5 mininutes and lift out bag
while it is still warm.

CHECK FAN Appears 10 min after the mes-
sage above if the problem is
a loose fan blade, blown fuse
(F3 or F4) or other fan-related
problem. Also appears if the
condenser is dirty.
Clean the Condenser. Run TEST
MODE to check for defective fan
motor. If necessary, check for a
loose fan blade or blown fuse
(see next section).
CHK HEATER FUSES Appears if the computer does not
detect a rise in tank temperature
after 15 minutes.
There may be a short circuit in
the Heater circuit causing fuse
F3 and/or F4 to blow or poor
electrical contact in the Heater
circuit. Check circuit condition
with a tester. Correct as required.
WARNING! VERY IMPORTANT! IF TRIAC IS FAULTY, DISCONTINUE USE IMMEDIATELY!
CHK HEATER TRIAC Short circuit in the TRIAC (a
switching transistor that controls
heater power, located on the
Power Control Board).
To confi rm, fi rst disconnect and
re-connect the power supply. If
the Distillation Tank becomes hot
to the touch and both the Heat
Light and the Fan Light are off ,
the TRIAC is defective. Discon-
nect the power supply imme-
diately and do not use again
until the Power Control Board
has been replaced.

SERVICE PROCEDURES
1) CLEAN CONDENSER
Remove the 2 screws at the back of the Side Cover and carefully move the Side Cover forward just
enough to reach the front of the condenser with a vacuum. Using a brush attachment, vacuum the front of
the condenser where most of the dust accumulates and then vacuum the back if necessary. Put the Side
Cover back into position and re-install the screws.
2) CLEAR BLOCKED SOLVENT FLOW PATH
CAUTION: WEAR SAFETY GOGGLES.
A blockage in the solvent fl ow path (Vapour Outlet - Condenser - Solvent Outlet Tube) can cause solvent
to leak. To determine the location of the blockage, fi rst check the Solvent Outlet Tube and the Vapour
Outlet Fitting for visible signs of blockage or damage. If the problem is not in either of these locations, the
Condenser is problably blocked. To clear the condenser, pour some clean solvent into the Vapour Outlet
and check if it comes out of the Solvent Outlet Tube. If the blockage persists, blow air at about 30 PSI (2
kg/cm2) into the Vapour Outlet. If the air comes out of the Solvent Outlet Tube, the blockage has been
cleared. If not, call for service.
3) REPLACE FUSES
Fuses are located on the Power Control Board inside the Motor Housing.
• Disconnect power supply.
• Remove the Guard Screen by unscrewing two metal screws to get access to the Motor Housing
• Unscrew the 6 screws from the Front Cover and pull it gently from the motor housing to expose the
fuses. Note: Care should be taken not to pull the Front Cover too far as some wires may discon-
nect.
Fuses F1 & F2: 240 VAC, 20A (URS2000) or 30A (URS2000PW & RI 80), 3AG, fast action, for Heater
Fuses F3 & F4: 25 VDC, 2.0 A, 3AG, slow action, for Fan Motor
Fuse F5: 240 VAC, 0.0625 A, 3AG, fast action, for Computer Board
• Remove the fuses from the board and, using a meter, test each one and replace as needed.
• Carefully push the Power Control Board back into the Motor Housing.
• Ensure that the wire to the computer board is secure.
• Re-install the Front Cover using all 6 screws..
• Install the Guard Screen using two metal screws.
• Close the Door and re-connect the power supply.

4) INCREASE LID TENSION (BY ADJUSTING THE SPRING BOLT)
CAUTION:
SHOULD BE DONE ONLY AS A LAST RESORT - FIRST CHECK FOR A WORN LID GASKET, A BLOCK-
AGE IN THE SOLVENT FLOW PATH , LOOSE HINGE BOLTS OR A SET POINT THAT IS TOO HIGH
FOR THE SOLVENT BEING RECYCLED.
5) REPOSITION LID and TIGHTEN HINGE BOLTS
The Hinge bolts can loosen over time, causing the lid to shift off center. This can lead to an inadequate
seal and leaking around the Gasket. Loosen the bolts, reposition the lid and re-tighten the bolts.
This procedure tightens the Lid by increasing
the tension on the spring attached to the Lid
Bar Spring Bolt Assembly. The Lid and Bolt
Assembly is carefully designed as a Safety
Pressure Relief system to prevent a danger-
ous build up of pressure inside the closed
tank. Do not adjust the Spring Holding Nut
by more than 2 full turns maximum. If 2
full turns do not solve the problem, call for
service.
• While holding the top nut with a wrench,
turn the Spring Holding Nut no more than
a 1/2 turn at a time. Turn in a counter-
clockwise direction (as you look down on
it).
• After each 1/2 turn, operate the unit nor-
mally and check for leaks.

6) RECOMMENDED 6-MONTH MAINTENANCE
• Vacuum the condenser (see Service Procedure 1).
• Clean the solvent fl ow path by recycling 3 Gal of clean solvent.
• Inspect Distillation Tank for debris, pitting and/or other damage.
• Inspect Lid Gasket for wear or damage (see Operating Procedure 11).
