This manual highlights Danger/Caution/Notice alerts to prevent injuries or property
damages and also to achieve optimum performance. Ensure to read the danger alerts and
caution alerts in 1.3 and 1.4 carefully before use.
These alerts are classified into three types in this manual depending on the importance and
the risk levels as described below:
Symbols
Meaning
Ignoring this danger alert can cause serious
injury or even fatal accident.
Ignoring this caution alert can cause injury
or property damage.
Ignoring this notice can cause operational
problems.
1.3 Danger Alerts
Ignoring the following warnings could cause serious injuries or even fatal accidents.

２
◆Check the required electrical requirements on the ID plate of this equipment before
use.
◆Connect this equipment to a dedicated power outlet nearby.
◆Make sure to connect this equipment only to properly grounded power outlets to
protect you and your instrument. Do not ground to gas pipes or water pipes.
◆Make sure to use the power cord supplied with this unit.
◆Never install or use this equipment in explosive or flammable atmospheres.
◆Never store flammable or hazardous substances near to this unit.
◆Never expose this equipment to any heat sources including direct sunlight.
◆Never allow water, organic solvents, dust, or corrosive gases to get inside the
equipment
◆Never put or insert any objects (especially if conductive or flammable) inside this unit.
◆If you observe a strange smoke, odor or noise from the equipment, unplug the power
cord immediately and turn off the main power switch. After the smoke or odor
disappears, contact your dealer or Jeio Tech if any repair is required.
◆Never disassemble, repair, or modify this equipment on your own. Doing so will void
your warranty and may result in injuries or product damages.

◆Always wear proper protective gear (such as goggles, gloves, masks or an apron)
when using this unit.

３
1.4 Caution Alerts
Ignoring the following cautions could cause injuries or property damages.
◆Do not place heavy objects, including this equipment, on top of the power cord and
do not strip, scratch, bend, twist, pull, or heat the power cord. A damaged power cord
is a fire and electrical shock hazard.
◆Make sure to set up this equipment on a flat, stable, clean, non-slip, dry, and fireproof
surface inside a lab with proper safety measures.
◆Do not place any device which can be affected by the motor vibrations near this unit.
◆Do not touch the power outlet, power socket, or power cord with wet hands. And
make sure to connect the power cord directly and firmly to the power outlet and
power socket.
◆Beware that mechanical shock or vibration can damage this equipment and pay extra
attention while moving it. Damages caused by mechanical shock or vibration may
result in injury or fire.
◆Do not install this equipment near any device that generates high frequency noise
such as high frequency welding machines, high frequency sewing machines, or SCR
power controllers.
◆Before cleaning, make sure to unplug the power cord to avoid electric shock or fire.
◆Do not use chlorine bleach, ammonia-based cleaners, abrasives, ammonia, or metal
scouring pads. Wipe with a soft damped cloth or a sponge soaked in water or diluted
neutral detergent.

2Description
2.1 Introduction
Jeio Tech is introducing nine new models of laboratory freezers with exceptional features
described in 2.3 to provide optimal freezing environments for your various scientific and
clinical applications such as storage of reagents, pharmaceuticals, test samples, plasma, and
other critical laboratory materials.
All FHG, FMG, and FCG Series laboratory freezers are equipped with a high-efficiency low
temperature refrigeration compressor and a directed airflow system ideal for superior
temperature uniformity, temperature stability, and rapid thermal recovery after door
openings.
2.2 Available Models
With respect to freezing temperature, three types of laboratory freezers are available:
FHG Series
FMG Series
FCG Series
Temperature Range
-15 to 0℃
-25 to -15℃
-35 to -25℃
FHG/FMG/FCG-150 FHG/FMG/FCG-300 FHG/FMG/FCG-650

５
And each Series offer three different chamber sizes to choose from:
FHG/FMG/FCG-150
FHG/FMG/FCG-300
FHG/FMG/FCG-650
Chamber Size
156L (5.5 ft3)
319L (11.2 ft3)
636L (22.4 ft3)
Dimension
(W x D x H)
763 x 871 x 975 mm
750 x 799 x 1610 mm
950 x 885 x 1980 mm
Therefore, depending on your specific requirements for the freezing temperature or the
chamber size, you can select the most suitable laboratory freezer among the following nine
models:
Temp. Range
Storage Capacity
-15 to 0℃
-24 to -15℃
-35to -25℃
156L
FHG -150
FMG-150
FCG-150
319L
FHG -300
FMG-300
