WARNING FOR THE VACUUM ASSIST UNIT
The operating staff must be fully instructed on the use and function of the unit as well as on the
correct application of the protection devices. The instructions must be repeated in regular intervals.
It is essential to keep the Instruction Manual inside the door slot of the Recycler or close to the
unit.
Operator must wear anti-static clothes, avoiding clothes made of synthetic material (nylon, rayon,
etc.).
When unloading residues, it is recommended to use gloves and an anti-vapor mask.
Do not use any metallic tools as they could provoke sparks.
The unit must undergo a revision and control according to its grade of use. Maintenance must be
carried out by qualified personnel and according to the indications of the Manufacturer.
Before using a Vacuum Assist unit, which has been out of use for a long time, it must be checked
and brought back into optimal condition in order to guarantee the operator’s security at all times.
According to the type of liquid to be distilled and the kind of operation to be performed, it is
important to adopt adequate personal protection rules.
Nitrocellulose which is an ester of cellulose and nitric acid and is a component in many lacquers,
inks, adhesives and cements cannot be recycled. It automatically ignites at 135°-166°C (275°-
330°F) and can be extremely volatile.
If repairs are necessary shut off the power supply IMMEDIATELY.
Do not smoke, cause sparks or use open flames near the recycler or vacuum assist units.

Feb 2021, Rev. 1.0 BECCA INC. Instruction Manual Vacuum Assist
10
WARNING FOR THE VACUUM ASSIST (cont’d)
Under these conditions, the unit shall be spaced a minimum of 5 feet (1.5 meters) from potential
sources of ignition such as electrical receptacles, switches, pilot light fixtures, contacts and other
similar equipment that can produce sparks. If the equipment is used in higher ambient
temperatures an increase in spacing from sources of ignition shall be considered.
PROTECTION OF THE NATURAL ENVIRONMENT
The user must provide protection of the environment so that the recycler may not be the cause for
emission of vapors or odors and that the residues are treated and disposed of in a correct way.
VACUUM DISTILLATION PRINCIPLES
The boiling temperature of the solvents reported on pages 26-27 of the Solvent Recycler Manual
are measured for atmospheric pressure operation of 1,000 hPa (760 mm Hg).
It is well known that by reducing the pressure, theboiling temperature of any substance is reduced.
When vacuum is created inside the distillation appliance, the boiling temperature is considerably
reduced.
With Units 9711-V and 9725-V, operating with vacuum, the distillation temperature is reduced
about 30%.
Vacuum distillation is recommended in the following cases:
1. When processing solvents with ignition point too close to their boiling temperature can create
a hazard or the solvent can degenerate and become an acid base and therefore cannot be re-
used. One of the most common solvents, that have this feature, is mineral spirit (varsol). This
solvent has a boiling point at 302°-374°F (150°-190°C) and its ignition point at 489°F (254°C).
2. When processing chlorinated solvents.
Atmospheric pressure distillation allows only a partial recovery of these solvents; at the end of
the process the residues will still contain 20% of solvents.
VACUUM DISTILLATION PRINCIPLES (cont’d)

Feb 2021, Rev. 1.0 BECCA INC. Instruction Manual Vacuum Assist
11
This occurs due to the fact that as long as the distillation process takes place, the percentage
of oil in the boiling solvent increases, so does the boiling temperature.
These solvents have a specific critical temperature which once exceeded, provoke the
decomposition of the solvents, causing the formation of hydrochloric acid with the consequent
acidity of the product, it will be impossible to re-use it. Operating with atmospheric pressure,
once critical temperature is reached will distill only 80% of the solvent. With vacuum distillation
it is possible to achieve a yield of 100% without reaching the critical temperature.

GRAPHIC (A) –(B)
The distillation temperature of a clean solvent remains the same until the process of the whole
cycle is complete.
GRAPHIC (C) –(D)
The distillation temperature of the contaminated solvents increases during the process; this
variation depends on the degree of contamination and on the type of contaminating substances.
GRAPHIC (C)
Once a temperature of 302°F (150°C) is reached, which is the critical non-supportable
temperature, only 80% of perchloroethylene will be recovered.

Operating with vacuum condition, 100% of perchloroethylene will be recovered when set at 248°F
(120°C) and very far from the critical temperature of 302°F (150°C).
When distilling chlorinated solvents, the vacuum distillation is indispensable; this type of process
is also necessary for minimal quantities of contaminants because of two specific reasons:
1. Yields 100%.
2. If the residual oil is contaminated with more than 2% of solvent, those oil waste-recycling
companies authorized for the waste collections will not accept it.

VACUUM DISTILLATION OPERATING METHOD
Before reading this section, it is compulsory to read the previous section regarding the distillation
at atmospheric pressure.
Unlike what occurs during atmospheric distillation, the distillation unit and the distillate collection
tank are a single body.
A pneumatic vacuum pump joined at the solvent recovery tank provides the creation of the vacuum
circuit.
Boiler Condenser Tank
The vacuum pump is fed with compressed air with a maximum negative pressure of 20-27 in.Hg.
(590 mm Hg) on the gage.
NOTE: MAKE SURE TO DISTILL SOLVENTS WITH DISTILLATION TEMPERATURE
HIGHER THAN 140°F (60°C) AT ATMOSPHERIC PRESSURE.
For example, distilling at vacuum condition the Acetone, which has a distillation temperature of
133°F (56°C) at atmospheric pressure, will reach a boiling point of 101°F (39°C). Since the
condenser is air cooled, if the temperature is higher than 70°F (20°C) you will obtain a partial
condensation of the solvent with an emission of Acetone vapor in the air.
OPERATING METHODS

VACUUM SYSTEM INSTALLATION
Placing your BECCA VACUUM ASSIST SYSTEM in accordance with the same procedures
as the Solvent Recycler. (See page 7 of the Solvent Recycler Manual) Use the VACUUM
ASSIST INSTALLATION GUIDE.
PRESSURE OF COMPRESSED AIR: 4 BAR
CONSUMPTION OF AIR: 32 L/MIN
STARTING OPERATIONS
NOTE: During vacuum distillation some solvents foamwith a consequent pollution of the distillate
and vapors may leak from the cover.
The problem can be eliminated as follows:
Utilize anti-foam discs.
Reduce about 20% of the loading of solvent to be distillate.
Reduce the compressed air pressure at the vacuum pump. In that way the vacuum will be
reduced.
Reduce the working temperature.
Wait at least 48 hours after utilizing the solvent before starting the next distillation.
When filling up, pay attention not to pour solvent into the vapor manifold. The first solvent can
come out dirty.

IMPORTANT NOTICE
1. Some solvents during the boiling phase create such a quantity of foam that a correct separation
of the solvent from the polluting product is not possible; in fact, in this case, the distillate will still
be dirty. To avoid this inconvenience, it will be necessary to obtain an anti-foam kit supplied as
an option.
824021 ANTI-FOAM KIT FOR: MODEL 1100 or 9711
824022 ANTI-FOAM KIT FOR: MODEL 25000 or 9725
2. Pay the utmost attention while the residue is drying; some polluting products with an increase
of temperature tend to carbonize with a considerable discharge of smoke from the apparatus.
IN CASE THIS OCCURS, IMMEDIATELY PRESS THE START / STOP KEY TO STOP THE
CYCLE.
In this case it is not possible to proceed to drying at atmospheric pressure; the problem may be
solved by proceeding to the distillation phase at atmospheric pressure and to the phase of
drying under vacuum; this technique will allow you to operate at a much lower temperature.
3. Opening the cover one hour before the distillation cycle is complete will cause the gasket to
swell.
4. Do not rotate and shake the unit once loaded or when operating.
5. The cover acts as a safety valve. In case vapors come out of the cover stop the unit
IMMEDIATELY and consult the table on page 29, "Defects, Causes and Remedies".
DO NOT MISHANDLE THE COVER LOCKING SYSTEM OR LOCK THE COVER IN ORDER
TO AVOID LEAKING.
6. Clean the diathermic oil expansion vessel only with a "wet" rag to avoid generating sparks.
