【Wait function explained】
If "starting temperature" and "temperature setting" are equal, chamber temperature is
maintained until timer reaches 0 (zero),.
If chamber temperature drops more than 3°C below or goes more than 6°C beyond
temperature setting, however, timer countdown stops and unit enters "wait mode" until
coolant temperature returns to within -3°C or +6°C of temperature setting. Timer then begins
counting down once again, from where it left off, until it reaches 0 (zero) and operation
finishes.

4. OPERATION PROCEDURE
Calibration Offset Function
The calibration offset feature makes it possible to compensate for any difference between the
temperature reading on the control panel and actual chamber temperature (taken manually). This
enables parallel compensation in either direction (+ or -) over the entire temperature setting
range on all DP series units.
Example
Actual chamber temperature is lower than the conrol panel temperature reading by 2°C:
Temperature reading can be calibrated by entering a calibration offset value of -2.0 to
compensate against the actual temperature deficiency of 2°C.
If the initial temperature reading was 200°C, it will read 198°C after offset calibration, and be brought
into agreement with the actual temperature.
※The -2°C calibration in the example above is applied over the entire temperature setting
range (0~250°C for DP200/300, & 0~210°C for DP410/610). Note that offset values may
change slightly depending on test sample arrangement in the chamber and/or
temperature setting.

4. OPERATION PROCEDURE
Independent Overheat Prevention Device
DP series units feature redundant safety devices: 1) The internal automatic overheat prevention
(automatic reset) feature, and 2) the Independent Overheat Prevention Device (IOPD) with
discrete power supply, circuit and sensor; completely independent of the CPU control board.
The IOPD main relay functions to activate and cut power to the heater when chamber temperature
goes too far beyond objective temperature.
These functions are enabled while the main power switch (ELB) is ON.
Set temperature on Independent
Overheat Prevention Device
(IOPD)
* Set temperature using the ▼▲ keys on IOPD
panel.
Operation may be terminated by Independent Overheat Prevention Device (IOPD) activation,
when IOPD temperature setting and target temperature are less than 20°C apart.
IOPD temperature must be set at least 20°C higher than target temperature.
Note: main function of IOPD is to keep DS unit from overheating, NOT to protect test samples from
damage. Likewise, it is NOT intended for protection against accident or injury resulting from the
negligent use of explosives and flammables.
IOPD factory settings and temperature setting ranges are shown below by model:
Model
Factory default
Temperature setting

DP200
270°C
0°C~270°C

0°C~270°C
DS410
230°C
0°C~230°C
DS610
230°C
0°C~230°C
To confirm whether IOPD functions as intended, set chamber temperature to any value within
unit specification range and allow temperature to stabilize. Gradually lower IOPD temperature
setting. If IOPD activates within 10°C of temperature setting, it is functioning normally.
Note: it normally takes 5 (five) seconds for IOPD to activate. Waiting 5 seconds each time
temperature is lowered in the confirmation test above, is therefore recommended. When IOPD
activates, error code Er07 shows in the display and operation will be terminated.
When changing the IOPD temperature setting, it takes a few seconds for the changes to finalize.
For this reason, wait 5 seconds after entering the change before turning the power off.
37
5. HANDLING PRECAUTIONS
Warning
1. DO NOT process hazardous or harmful substances.
Never process explosive or flammable items. Fire or explosion causing serious injury or death
may result. See “List of Hazardous Substances” (P.58) for more information on these items.
2. DO NOT operate equipment when abnormalities are detected.
If unit begins emitting smoke or abnormal odors for reasons unknown, turn off main power
(ELB) immediately, disconnect power cable from power supply, and contact a local dealer or
Yamato sales office for assistance. Continuing to operate without addressing abnormalities
may cause fire or electric shock, resulting in serious injury or death. Never attempt to
disassemble or repair unit. Repairs should be always be performed by a certified technician.
Caution
1. DO NOT climb on top of equipment.
Do not attempt to climb onto unit or substitute it for a proper step ladder. Units are not
designed to support bodily weight and damage may result. In addition, unit may become
unstable and tip over or fall resulting in equipment damage, serious injury or death.
2. DO NOT place items on top of equipment.
Do not place any objects on unit. Doing so may cause unit to become unstable and tip over,
resulting in possible equipment damage, injury or death.
3. DO NOT operate equipment during thunderstorms.
In the event of a thunderstorm, turn off main power switch (ELB), and disconnect power cable
immediately. A direct lightning strike may cause equipment damage, fire or electric shock,
resulting in serious injury or death.
4. DO NOT leave chamber door open after operation.
Do not leave DP unit door open (i.e. to cool test samples in the chamber down, etc.) following
an operation run. Heat from chamber may damage and/or deform control panel, causing CPU
board malfunction or failure. Always remove processed test samples and close chamber door.
5. DO NOT process corrosive items.
Do not process items containing corrosive chemicals of any kind. Although chamber interior is
manufactured of 304 stainless steel, damage may still occur from exposure to strong
chemicals. Likewise, vacuum lines contain copper and nylon, which are easily damaged by
corrosive substances. Avoid processing test samples which contain corrosives such as acid
alkaline, heavy metal salts, etc. or solvents such as halogens, aminities, esters, etc.
6. ALWAYS run equipment within specified temperature range.
Operating temperature range is 40°C~240°C for DP200/300 and 40°C ~200°C for DP410/610.
Never attempt to operate unit outside of the above specified temperature range. Doing so may
cause equipment malfunction or damage.
38
5. HANDLING PRECAUTIONS
Caution
7. Arrange test samples appropriately.
Weight capacity for one chamber rack is approximately 15kg. Test sample load total for each
rack should thus not exceed this specification.
Arrange test samples evenly on racks, leaving as much space between them as possible.
Test
samples
15 kg max
Chamber rack
Do not place too many test samples on rack at once. Doing so may prevent proper temperature
control in chamber. Test samples should be managed in the following way;
1. Install the supplied chamber racks, 2. Leave as much space between test samples as
possible. 3. As a rule of thumb, leave 30% or more of the total space on each rack unoccupied.
Leave 30% of total rack space open
8. DO NOT place items in bottom of chamber.
Operating unit with test samples placed directly on bottom surface of chamber may cause unit
to perform poorly. Likewise, chamber temperature may become excessive, causing malfunction
or damage. Always use the supplied chamber racks, supported on the standard guide rails, to
avoid placing items directly on chamber floor. Further, do not allow test samples to contact
chamber walls.
9. Power outages.
In the event of a power loss during operation, one of the following will occur when power is
restored, depending on what settings have been selected:
● Continued operation: if power recovery settings have been set to continue (factory
default), the START/STOP key can be pressed and operation will pick up where it left off
with the power failure.
● Stop operation: if recovery settings have been set to stop, operation will be terminated
and unit will go into idle when power is restored.
See “Recovery Modes” (P.33) for details.
10. Confirm equipment stability.
If unit has not been stabilized, it may tip over or fall, causing injury or death, during an
earthquake or other unforseen incident. Be sure to stabilize unit properly (adjustable leveling
feet securely positioned, etc.) to ensure safe operation.
39
5. HANDLING PRECAUTIONS
Caution
11.Chamber door seal.
Chamber door seals are manufactured of silicon rubber. Benzoic acid, oil, and other
components, used during the silicone rubber manufacturing process, may be emitted during
operation, spoiling incompatible test samples. If test samples, sensitive to silicone rubber
by-products, are to be processed; specially formulated fluoro-rubber seals may be requested as
an option.
Note that acids, alkaline, and halogenated solvents are all corrosive to rubber.
【Caution】
Substances which are corrosive to the silicon or fluoro rubber used for chamber door seals are
shown in Table 5.1.
Do not process test samples that contain any of the substances shown in this table.

13. Inspect equipment regularly.
The main power switch (ELB) and Independent Overheat Prevention Device (IOPD) in
particular, are key devices in maintining the safety of DP series units, and must be
inspected/maintained regularly.
See “Inspection & Maintenance” (P.43) for details.
14. Independent Overheat Prevention Device activation temperature must be set.
Activation temperature for the Independent Overheat Prevention Device (IOPD) must be set in
order to protect unit from damage, should overheating occur.
Note that temperature on the IOPD should be set 20°C above chamber temperature setting.
See “Independent Overheat Prevention Device” (P.37) for more on setting up this
device and for other warnings.
15. Solvents and excess moisture in test samples.
Remove excess and unneeded moisture and water from test samples (i.e. thoroughly dry test
sample container exterior, etc.) before processing.
A cooling trap, such as model CA301/801 by Yamato Scientific, should be installed between the
chamber and vacuum pump, particularly when processing test samples containing organic
solvents. This device will dispel gases/fumes thrown off by processing caustic test samples,
and prolong the life of vacuum lines, door seals and other system components that are easily
damaged by solvents.
41
5. HANDLING PRECAUTIONS
Caution
16. Samples/specimens containing powder.
Powder may spew suddenly from unit if purge valve or pump valve is opened abruptly with
chamber still decompressed. Open these valves and restore normal pressure gradually when
processing test samples containing powder or micro-particle substances.
17. High temperature operation.
When running DP series units at high temperature, exercise extreme caution so that hands and
skin do not contact hot surfaces. Always wear heat-resistant gloves when inserting and
removing test samples/specimens from oven chamber.
Also note that extended high temperature use may cause chamber door seal to become
adhered to window glass, preventing the door from being opened. Avoid more than 72 hours of
continuous operation.
18. Shutting vacuum pump down.
Shut vacuum pump down using following procedure:.
1) Close pump valve.
2) Gradually open purge valve.
3) Confirm that ambient pressure has been restored to chamber.
4) Open pump valve, then shut down vacuum pump.
Warning: oil from the vacuum pump may flow backward into the chamber, if vacuum pump is
shut down with chamber decompressed.
19. Maintaining chamber decompression.
To keep chamber decompressed, leave the vacuum pump running with the pump valve open.
Warning: oil from the vacuum pump my enter the vacuum lines if pump is shut down with valve
closed.
20. DO NOT apply paint thinner, alcohol or other solvents to equipment.
Never attempt to clean DP series units with paint thinner, alcohol or solvents of any kind. Doing
so may cause coating to peel, discoloration, superficial damage and deformity to some
components.
Note: Always turn off main power switch (ELB) prior to cleaning or maintenance.
21. Read instruction manual before operation.
Always read instruction manual(s) for all equipment, thoroughly, before beginning setup,
installation or operation.
22. DO NOT remove polycarbonate covering from window.
Do not attempt remove polycarbonate covering from outer surface of viewing window. The
viewing window itself can shatter from even the smallest scratch (even those not seen with the
naked eye) or impact. The polycarbonate covering acts as a protective screen in the event of
such incidents.
Covering may cloud over time, depending on operating environment and use. Do not attempt to
replace covering. All such repairs should be done by a certified technician.

6. MAINTENANCE PROCEDURE
Inspection and Maintenance
Warning
● Be sure that main power switch (ELB) is OFF before daily inspection and maintenance of DP series
units.
● Perform inspections and maintenance when inside of chamber is at room temperature.
● Never attempt to disassemble unit.
Caution
● Clean unit using soft damp cloth.
● Never use benzene, paint thinner, scouring powder, scrubbing brush or other abrasives and
solvents to clean unit. Superficial damage and/or discoloration, as well as deformity to some
components may result.
Inspect monthly.
● Inspect main power switch (ELB) ON and OFF function.
・Prepare unit for inspection by connecting power cable to a facility outlet or terminal.
・Confirm that main switch (ELB) is “OFF” then, turn main switch (ELB) back “ON”.
・With the main switch “ON”, depress the test button on the main switch (ELB) using a ball-point pen
or other fine-tipped object. If main switch (ELB) shuts off, it is functioning normally.
● Test Independent Overheat Prevention Device (IOPD).
・Run unit in constant temperture mode and allow temperature to stabilize.
・Set the activation temperature for the IOPD to approximately 5C below chamber temperature.
・If overheating prevention device is functioning normally, heater will shut off within few seconds and
error code “Er07” will appear in the upper display. An alarm will also sound and ERROR lamp will
illuminate.
*Main power switch (ELB) and overheat prevention device must be inspected, as prescribed above,
prior to every instance of extended or overnight operation.
● Check oil level of vacuum pump (sold separately).
・Check oil level in vacuum pump at least once a month. Add or change oil as required.
・Check pump oil periodically and change ahead of specified life span, if possible. Depending on
operation environment and other factors, oil may degrade quickly and cause poor performance or
damage to pump.
・See vacuum pump instruction manual for additional information on oil changes.
・Having vacuum pump overhauled annually by original manufacturer is recommended for best
performance.
