1. SAFETY PRECAUTIONS
Warnings and Cautions
WARNING
Install in a location free of flammables and explosives.
Never install or operate unit in a flammable or explosive gas atmosphere.
See "LIST OF HAZARDOUS SUBSTANCES" (P.44 ) for information on flammable and
explosive gases.
Ground wire MUST be connected properly
・Connect power cable to a grounded outlet in order to avoid electric shock.
・Never connect ground wire to gas lines or water pipes. ･ Fire, accident or equipment
malfunction may result.
・Never connect ground wire to telephone grounding lines or to lightning conductor rods.
Fire or electric shock may result.
･ Never insert multiple plugs into a single outlet. Doing so may result in power cable
overheating, fire or drop in voltage.
Connect power cable properly
Insert power cable firmly into the AC adapter inlet. Failure to do so may result in
overheating, fire, and/or electric shock.

1. SAFETY PRECAUTIONS
Warnings and Cautions
Turn OFF (○) power immediately when an abnormality occurs.
If unit begins emitting smoke or abnormal odours for reasons unknown, turn OFF (○)
power immediately, disconnect power cable from power supply, and contact original
dealer of purchase 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 always be performed by a certified technician.
Handle power cable with care.
･Do not operate unit with power cable bundled or tangled. Operating unit with the power
cable bundled or otherwise tangled, may cause power cable to overheat and/or catch
fire.
･Do not modify, bend, forcibly twist or pull on power cable. Fire or electric shock may
result.
･Do not risk damage to power cable by positioning it under desks or chairs, or by allowing
it to be pinched in between objects. Fire or electric shock may result.
･Do not place power cable near kerosene/electric heaters or other heat-generating
devices. Doing so may cause power cable insulation to overheat, melt and/or catch fire,
which may result in electric shock.
･Turn OFF (○) power immediately and disconnect from facility terminal or outlet, if power
cable becomes partially severed or damaged in any way. Contact original dealer of
purchase for information about replacing power cable.
Failure to do so may result in fire or electric shock.
･Always connect power cable to appropriate facility outlet or terminal.
DO NOT disassemble or modify equipment
Never attempt to disassemble or modify unit. Doing so may cause malfunction, fire,
electric shock, or personal injury. Note that any malfunction resulting from unauthorized
modifications or customizations to unit will void the warranty.
Exercise caution when handling flammable chemicals.
Unit is NOT fire or blast resistant. When processing flammable samples, be sure to
provide adequate ventilation and not to allow anything that may be a source of fire or
ignition (static electricity, etc.) approached. Do not use this unit in an atmosphere of
substances shown in LIST OF HAZARDOUS SUBSTANCES (P.44). Never vaporize
explosive substances. Fire or explosion causing serious injury or death may result.
CAUTION
DO NOT operate equipment during thunderstorms
In the event of a thunderstorm, turn OFF (○) power and disconnect power cable
immediately. A direct lightning strike may cause equipment damage, fire or electric shock,
resulting in serious
injury or death.

3. PRE-OPERATION PROCEDURES
Installation Precautions
Connect the power supply of this unit to BM312-G (BO312-G).
The power cable attached to this unit is exclusively for BM312-G (BO312-G) connection.
When using it, connect it to BM312-G (BO312-G) and do not use any cable other than the
dedicated cable.
Install in a dry location.
Install unit where it will be free from
liquid spray and other moisture.
Failure to do so may result in control
mechanisms becoming wet, causing
malfunction, electric shock and/or fire.
Pay attention to the surroundings whenever operating jack.
Do not place any objects under the slide
panel. Such objects may cause damage
to unit or personal injury when using the
jack handle.
Always lower the slide panel slowly to
prevent damage to glassware on contact
with the bath

3. PRE-OPERATION PROCEDURES
Installation Procedure
Be aware that slide panel may spring up
Slide panel on this unit employs a spring-loaded jack to lift it up.
The spring tension is adjusted to achieve balance when all the connection with glassware
and piping are made.
The panel jumps up when releasing the lock of the jack without glassware mounted.
Be sure to hold
the
t
op of the slide panel by hand whenever re
leasing the lock.
Always install glassware and piping with the slide panel lifted up.
If the lock of the jack is unintentionally released while setting up glassware and piping,
there is a risk of damage to glassware, and/or personal injury.
1. Jacking up
(1) Release the lock by turning jack handle
counterclockwise while holding the slide panel
top.
Hold the slide panel tightly or it may jump up.
(2) Lift up the slide panel to top, turn the handle
clockwise to lock.
2. Motor box tilt adjustment
(1) Hold motor box by hand and turn tilt
adjustment screw counterclockwise to
release the lock.
(2) Motor box can now rotate. Rotate the box to
the position for use and turn tilt adjustment
screw clockwise to lock the driving unit.
(3) Adjust the control panel angle for better
visibility
Tilt the driving unit at about 30° before
installation.

Installation Procedure
5. Installing vacuum seal
Pay attention to the direction of vacuum seal.
Installing vacuum seal in the opposite direction may lead to poor vacuum, or may wear the
seal, resulting in damage to
driving unit.
Install vacuum seal.
Fit vacuum seal into the housing by
passing it on Vapor Tube with the side
where the spring is visible facing motor
box.
Be sure to install vacuum seal after Vapor
Tube is set, to prevent damage to vacuum
seal.
Make pipe connection properly
Be sure to install all tubing in right positions. Improper connection and looseness of nozzle
caps may cause leakage or damage to
peripherals.
6. Installing nozzle unit
Nozzle unit has two types, with gre
y cap and
black cap.
Grey: for vacuum line
Black: for cooling water line
Three parts of “Nozzle”, ”Nozzle cap”,
and ”Nozzle gasket” comprise the nozzle
unit.
Ensure that nozzle gasket is placed in
nozzle cap.
① Screw down nozzle cap against nozzle
receptacle on cooling condenser.
② Turn nozzle cap clockwise to fasten.
