1. SAFETY PRECAUTIONS
Warnings & Cautions
WARNING!
Never operate equipment near combustible gases/fumes.
Do not install or operate this unit near flammable or explosive gases/fumes. Unit is NOT fire or blast
resistant. Negligent use could cause fire/explosion. Refer to “List of Hazardous Substances” (P.29).
Always ground equipment.
Always ground this unit properly to avoid electric shock.
DO NOT operate equipment when abnormalities are detected.
If smoke or unusual odors begin emitting from unit, or if any other abnormalities are detected, terminate
operation immediately, turn off main power switch (Earth Leakage Breaker - “ELB”) and disconnect
power cable. Continued operation under such conditions may result in fire or electric shock.
DO NOT operate with bundled or tangled power cable.
Operating unit with the power cable bundled or otherwise tangled, may cause power cable to overheat
and/or catch fire.
DO NOT damage power cable.
Damaging the power cable by forcibly bending, pulling or twisting may cause fire or electric shock to the
operator.
DO NOT handle flammable substances without proper ventilation.
Be sure there is adequate ventilation when working with certain flammable substances (such as
ethanol, etc.), which evaporate quickly at or below room temperature, and emit flammable fumes.
Insufficient ventilation may cause a fire or explosion. Refer to “List of Hazardous Substances” (P.29).
DO NOT disassemble or modify equipment.
Attempting to dismantle or modify unit in any way, may cause malfunction, fire or electric shock.
Keep unit upright.
Never attempt to turn or place unit on its side while moving or transporting. Damage to refrigeration
system may result. If briefly tilting unit to one side or the other is unavoidable during transport, refrain
from turning power on for at least 24 hours after positioning unit upright.

1. SAFETY PRECAUTIONS
Warnings & Cautions
CAUTION!
DO NOT operate equipment during thunderstorms.
In the event of a thunderstorm, terminate operation and turn off main power switch (ELB) immediately. A
direct lightning strike may cause damage to equipment, or result in fire or electric shock.
DO NOT touch condensate in cold trap.
Condensate and inner surfaces of cold trap may become extremely cold during operation or right after
operation. Avoid contact with bare hands/fingers in order to prevent severe frostbite.
DO NOT touch cooling fins.
Edges of cooling fins are very sharp. Do not contact with bare hands or skin. Laceration injuries may
result.

2. PRE-OPERATION PROCEDURES
Installation Precautions & Preparations
WARNING!
1. Choose an appropriate installation site.
● Do not install unit:
・ where installation surface is not
completely level, not even or not clean.
・ in excessively humid or dusty locations.
・ where power supply is erratic.
・ where ventilation is not sufficient
・ where flammable or corrosive
gases/fumes will be generated.
・ where external temperature will exceed
30ºC, will fall below 5ºC or will fluctuate.
・ where there is constant vibration.
・ in direct sunlight or outdoors
Install unit in a location with sufficient space as specified below.
More than
20cm
More than
20cm
Front side
More than 40cm
2. Install unit in a safe, well-ventilated area.
In the event of an earthquake or other unforeseen incident, equipment may unexpectedly shift or
fall, causing injury. Taking preventative steps to install unit in a safe location, away from room
access doors and out of other danger is strongly recommended.
This unit is equipped with an air-cooled refrigerator. Install unit in a well-ventilated or
air-conditioned place so that unit is allowed to sufficiently diffuse heat. Failure to do so may
cause ambient temperature to rise, resulting in possible degraded cooling performance, overload
on the refrigerator, or equipment malfunction.
3. Install in a location free of flammables and explosives.
● Never install near flammables or
explosives. This unit is NOT fire or blast
resistant. Simply switching the main
power switch (ELB) “ON” or “OFF” can
produce a spark, which can relay during
operation, causing a fire or explosion
when near flammable or explosive
fluids, chemicals or gases/fumes.
Refer to “List of Hazardous Substances”
(P.29).

2. PRE-OPERATION PROCEDURES
Installation Precautions & Preparations
4. Never disassemble or modify. 5. Install on a level surface.
Attempting to disassemble or modifiy this
unit in any way may result in malfunction,
fire or electric shock.
Install unit on a level and even surface.
Failure to do so may result in abnormal
vibrations or noise and damage to the
refrigeration system.
Approximate unit weight is 65kg.
Handle with care. Transport and
installation should always be
performed by two or more people.
6. Ensure adequate amount of unit ventilation.
Do not operate unit with ventilating openings (front, side, rear) obstructed.
Doing so may cause excessive temperatures inside unit, resulting in degraded performance,
malfunction or fire.
7. Install in a dry location.
Install unit where it will be free from fluid spray and other moisture. Failure to do so may result in
malfunction, electrical shock and/or fire.
8. Connect to a proper power supply.
Connect power cable to a suitable facility outlet or terminal, according to the following
electrical requirements.
Electrical
requirements: AC100V±5% 7/6.5A 50/60Hz (15/14.5A when optional pump & heater is
used)
NOTE)
Check the line voltage on outlet or terminal to be used and properly evaluate whether to
utilize a line being shared by other equipment. If unit is not activated by turning on the
main power switch (ELB), take an appropriate course of action, such as connecting unit
to a dedicated power source.
If multiple power cables are connected to a single outlet, input voltage to unit may drop,
causing degraded cooling and temperature control performance.

Installation Precautions & Preparations
CAUTION!
9. Handle power cable with care.
Never operate unit with power cable bundled or tangled; and do not modify, bend, forcibly
twist or pull on power cable. Doing so may cause fire and/or electrical shock.
Do not risk damage to power cable by positioning it under desks or chairs, or by pinching
it between objects. Doing so may cause fire and/or electrical shock.
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 main power switch (ELB) immediately and disconnect from facility terminal or
outlet, if power cable becomes partially severed or damaged in any way. Failure to do so
may result in fire or electric shock.
Contact a local dealer or Yamato sales office for information about replacing power cable
if it is damaged.
Always connect power cable to appropriate facility outlet or terminal.
10. Equipment MUST always be grounded properly.
Where no grounding terminal is provided, contact a local dealer, electrician or Yamato sales
office for location-specific electrical requirements.
･Connect terminals securely to facility terminal or to an appropriate connector.
Plugs and connectors are not included with this
unit. Ground unit properly to facility outlet or
terminal as required.
Never connect ground wire to gas lines, water pipes, telephone grounding lines or lightening
rods. Doing so may result in malfunction, fire or electrical shock.
11. Observe wire color designation. See table below.
Confirm that the facility main breaker is OFF before
connecting the round terminals from the power cable. No
power plugs or connectors of any kind are included with
this unit. Where required, purchase an appropriate plug
and properly connect using the round terminals.
