1.Safety precautions
Warnings & Cautions
Warning
Never operate the unit in an atmosphere containing flammable or explosive gas
Never operate the unit in an atmosphere containing flammable or explosive gas.
Otherwise, an explosion or a fire may result since the unit is not explosion-proof.
See section “13. List of dangerous materials” on page 24.
Be sure to connect the ground wire.
Be sure to connect the ground wire correctly. Otherwise, electrical leak may result and cause an
electrical shock or a fire.
Ban on operation when an abnormality occurs
When a smoke or an unusual odor is seen or sensed, immediately turn the ELB on the main unit
off and pull out the power plug.A fire or an electrical shock may result.
Never use electrical power cords bundled.
When these are used bundled, they might overheat causing a fire.
Take care not to damage electrical power cords.
Avoid tightly bend, pull with a strong force or twist to prevent electrical power cords from
damaging.A fire or an electrical shock may result.
Ensure sufficient ventilation when using flammable and combustible solutions.
If left at the room temperature (or below for certain solutions), flammable and combustible solutions
(ethanol, etc.) may be vaporized and thus ignited and exploded by any ignition source (switch, etc.).
Never try to disassemble or alter the unit.
Never try to disassemble or alter the unit.A malfunction, a fire or an electrical shock may result.
Do not place the unit on its side.
Never place the unit on its side during transfer/transport because the refrigerator may suffer failure.
If the unit is to be tilted toward its side temporarily during carry-in, do not turn ON power supply for at
least one day (24 hours) after completion of carry-in.

1.Safety precautions
Warnings & Cautions
Warning
When a thunder is heard.
When a thunder is heard, turn the main power off immediately. A malfunction, fire or an electrical
shock may result.
Keep hands away from the condensate and wall surface of the trap tank.
Condensate and wall surface of the trap tank becomes cold during operation and for a certain period
of time after operation. If you touch it, you will suffer frost bite. Never touch the condensate.
Do not touch the condenser fin with bare hands.
Never touch the condenser fin with bare hands during maintenance. The fin has sharp edge and
may cut hands.

Cautions for installation
Warning
1. Take care to select an appropriate installation site.
Avoid installing the unit, above all, in places listed below:
・Uneven or dirty floor
・Where floor is not level.
・Where temperature may
change widely.
・Where humidity is high.
・Where subject to direct
sunlight.
・Place with unstable power
supply.
・Where flammable gas or corrosive gas may exists.
・Where environmental temperature is 5℃or less or
30℃or over.
・Not well-ventilated place.
・Where vibrations are severe.
・Outdoor
Install this unit at a place with spaces shown below.

2. Installation
The unit might fall down or move by an earthquake or an impact resulting a personal injury.
We recommend making safety measures such as to avoid installing the unit at a place other
than busy places. This trap incorporates an air-cooling refrigerator, which produces waste
heat. Use the trap in a well-ventilated or air conditioned place to prevent rising of the ambient
temperature. Higher ambient temperature causes drop of operation efficiency. Moreover,
the refrigerator is put into high-temperature high-pressure operation, resulting in failure.
3. Never operate the unit in an atmosphere containing flammable or explosive
gas.
Never operate the unit in the flammable or combustible gas atmosphere. This unit is not of
an explosion-proof structure，and ON/OFF switching and operation may cause arc, resulting
in explosion and fire.
For flammable and explosive gas, refer to “13. List of Hazardous Materials” in page 24.

Warning
4. Never attempt modification.
5. Install the unit on a level surface.
Never attempt modification by the
customer so as to prevent failure.
Install the unit on a level surface.
Accidental trouble or failure may occur unless
the product is installed a level surface.
The product weighs about 65 kg. When
lifting the unit for transportation and
installation, carefully handle it by at least
two people.
6. Secure sufficient ventilation for the unit.
Do not operate the unit when its front/side panels and vent holes are blocked.
Internal temperature of the unit will rise degrading the performance and an accident, a
malfunction or a fire may result.
7. Do not operate the unit at such a place that may subject to splash.
Do not operate the unit at such a place that may subject to splash. Liquid entering the inside
may cause an accident, a malfunction, an electrical shock or a fire.

8. Be sure to connect the earth wire.
・Be sure to connect the earth wire (green wire of the power cord) to the earth wire or to
the earth terminal.
・Never connect the earth wire to the gas pipe or water pipe, in order to prevent fire.
・The earth wire must never be used for grounding of the telephone line and lightning
arrestor. This is to prevent fire and electric shock.
・Never use the branch socket outlet because it causes hazardous heat generation.
Used of ground socket outlet recommended
Ground socket outlet
When there is no ground terminal.
●In this case, class D grounding work is
necessary and please consult your dealer or
our customer service center.
When a bipolar type outlet tap is used
Ground adaptor
●Insert the ground adaptor included as an
option, into a power plug confirming the polarity
of the outlet. Connect the grounding wire
(green) of the ground adaptor to the ground
terminal on the power supply equipment.
9. Use a dedicated outlet for the power supply.
Use a power supply that meets the electrical capacity of the unit.
Electrical capacity:：AC115V±5％50/60Hz 6A
When the unit will not start even when you turn the power switch to “ON”, check for low main
voltage or if the unit is connected to the same power supply line as other devices and
connect it to another line if necessary. Avoid using wire extensions using a cord reel, which
may result in degradation of freezing capacity or stoppage of refrigerator from possible
voltage drops. Do not connect too many wires to a single outlet using a branching adaptor.
Otherwise, a fire or an electric shock may result.
