4) DEFINITIONS:
➢Flash Point or Flash Point Temperature.
Flash Point or Flash Point Temperature is the lowest temperature at which the vapor of a
solvent can be made to ignite momentarily in air by a source of ignition. Use only non-
flammable solvent with a flash point between 100°F to 143°F (37.8°C to 61°C) in this unit.
➢Auto-ignition Temperature (often referred to as “Ignition Temperature” or
“Ignition Point”): The temperature at which solvent ignites by itself. The lowest ignition
point of the solvent to be used in this unit is 392ºF (200ºC).
➢Boiling Point Temperature: (often referred to as “Boiling Point”or “B.P.”)
The temperature at which solvent starts to boil and turn into solvent vapor. The highest
boiling point of the solvent to be used in this unit is no higher than 374ºF (190ºC).This unit
performs distillation under strong vacuum which is known to lower the boiling point. On the
other hand, contaminants like oil and grease that go into the cleaning solvent during the
cleaning operation are known to raise the boiling point depending on the extent of
contamination.
➢Set-point Temperature.
This unit is pre-set at factory to Set Point temperature of 338ºF (170ºC), which is the
highest temperature available for distillation. This, however, does not mean the
temperature of Distillation Tank always goes up to the Set Point temperature. Actual
temperature of Distillation Tank displayed by LCD stays at lower level during distillation and
starts rising to the Set Point toward the end of distillation process. It will reach Set Point
when there is no solvent in Distillation Tank.
Note1. Source of information for definition of non-flammable (combustible) solvent are; The
National Fire Protection Association, The US Department of Transportation, The US
Environmental Protection Agency, The US Occupational Safety and Health Administration

3) SOLVENT REQUIREMENTS AND SELECTION:
To ensure safe and effective use of this equipment, it is important to choose correct cleaning
solvent. This equipment is designed, constructed and certified to be used with non-flammable
(combustible) solvent. Carefully check the MSDS (Material Safety Data Sheet) supplied with
the solvent to ensure all three requirements listed below are met.
➢Flash point between 100°F to 143°F (37.8°C to 61.6°C). (See Note 1. below)
➢Boiling point 374°F (190°C)
➢Auto-ignition point 392 °F (200°C).
➢Solvents have relatively high LEL (Lower Explosive Limit)
➢Solvent and its vapor are not harmful to the health of operator.
➢Solvent and its vapor do not have objectionable odor.
A total of 30 US Gallons (113.5 Liters) of the cleaning solvent is required at start up. 25 US
Gallons (94.6 Liters) are required to fill Clean Solvent Tank and 5 US Gallons (18.9 Liters)
must be poured into Duty Solvent Tank. (Refer to page 10, Filling solvent)
We recommend to use the solvents with Flash Point of between 100°F to 143°F (37.8°C to
61.6°C), Autoignition Temperature of 392°F (200°C), and Boiling Point 374°F (190°C), for
the reason of minimal evaporation loss.
TURN THE MACHINE OFF WHEN ADDING SOLVENT. DO NOT add solvent
during the recycling process. Regularly drain residue from drain valve.
DO NOT drain residue when drain valve is hot after recycling, wait until the knob
is cool to the touch. Periodically clean the removable sink strainer. Never operate
machine without the strainer.
4) INITIAL FILLING OF CLEAN SOLVENT:
Machine does not come with Solvent and before you operate the machine, it required filling
the clean solvent and also from time to time, it becomes
necessary to add solvent to the CLEAN SOLVENT TANK because
of loss by evaporation, drag-off and waste removal. When the
Level Sensor in the CLEAN SOLVENT TANK detects the low
solvent level, the Display will read “FILL CLEAN TANK”; an alarm
will start sounding and continue until clean solvent is added to the
Clean Solvent Tank as follows:

➢The oily debris or residue may be drained easily by opening Drain Valve located at the
bottom of Distillation Tank as shown in the photo on age 14.
•Do not drain until the distillation has been completed. Wait until the system completes the
recycling process and cools down with LCD showing “READY TO RECYCLE + PRESS START
3SEC” and on the second line “READY TO CLEAN + PUSH PUMP BUTTON”.
➢Open drain valve by turning Drain Valve Handle to vertical position and debris will drain into
Debris Drawer. Leave the Drain Valve open as long as necessary. However, make sure to
close Drain Valve before the next recycling operation.
➢Check and empty Debris Drawer as required.
Note: The amount of debris accumulation will vary with the usage of
Parts Washer. Under normal conditions, 2 to 3 quarts (about 2 to 3
Liters) of oily debris would be drained on a weekly basis. Drain debris
more or less often as required.
Note: If the debris is too thick to drain through Drain Valve, it is
recommendable to add a cup of used oil into the Sink Strainer
before starting recycling process (See the photo on page 13.)
4 –PERIODICAL MAINTENANCE.
a) Blockage of Drain Valve
➢Large Clean-out hole of about 4.2” ID ( 10.7 mm ID) covered by a Cap with internal threads
is provided for the convenience of periodical inspection and cleaning of Boiler Tank bottom
and drain passage of Valve if necessary.
➢If draining debris from Drain Valve is found difficult, accumulation of solid debris at the
bottom of Boiler Tank might be suspected.
CAUTION:
•To prevent risk of accidental electric shock, make sure to turn off power supply before
starting this maintenance procedure.
•To protect your hands, always wear gloves.
➢While LCD in Key Panel is showing READY status, remove Clean-out Cap by using
Removal Tool (Part No. 230-1124) which is included in the Accessory Kit received with the
unit.
➢Check and remove solid debris and contaminant as required through the clean-out hole.
Note: Do not use metal tool to avoid any damage to two heaters installed in the vicinity of
boiler tank bottom.
➢After completion of cleaning inside of boiler tank, make sure that the threads and O-ring of
the Clean-out Bushing are clean and free of any damage. Apply a drop of oil to the threads
and O-ring for lubrication. Put the Cap back by turning clockwise. Just tighten softly. Do not
over-tighten which is totally unnecessary.
WARNING

WARNING
The Clean-out Cap will be hot to the touch during the recycle
process. Do not open or touch the cap while the recycle
process is operating or until the unit shutdown after cooling
and LCD on the control panel shows READY status...
5 –TOPPING UP CLEAN SOLVENT
During a long usage for parts 2washing operation, the cleaning solvent is lost due to
natural evaporation, carried away with the parts cleaned, waste cloth, etc.
When the Level sensor installed in the Clean Solvent Tank detects the low level, LCD
shows “FLUID LEVEL LOW”and “FILL CLEAN TANK” and also beeps for 1 second.
H. CONTROL PANEL PROCEDURES
Control panel (Keypad) is provided on the Computer Box located at the right top of Base
Cabinet. Control panel is made of durable and wear and solvent resistant material.
A back-lit LCD with 32 character display (16 characters in two lines.) is provided to display
variety of messages including operation status messages, warning or error messages, etc.
and functions as important communication media between the equipment and operator.
(Refer to page 17 for List of messages)
Add clean solvent into Filling Port located in the right
rear corner of the Sink by using a Funnel or Uni-ram
Pumping Station (Optional, See page 9).
Carefully observe the Over-Flow Jet as the clean
solvent starts flowing out from the Over-Flow Jet when
Clean Tank is full.
