1.1 Read before Installation
1.2 Signal Words for Safety
BEFORE INSTALLATION, READ THIS MANUAL
This manual includes installation procedures and safety precautions for installing the NIDEK
edging station LE-700.
Be sure to read this manual and operator’s manual carefully and understand their contents
before installation.
In this installation manual, signal words are used to designate the degree or level of
safety alerting. The definitions are as follows.
WARNING
Indicates a potentially hazardrous situation which, if not avoided, might result in death or
serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, might result in minor or
moderate injury or a property damage accident.
Even situations that are labeled CAUTION might result in serious injury under certain
conditions.
Safety precautions must be followed strictly at all times.

FOR SAFE INSTALLATION: During Installation
1.3 During Installation
WARNING
• Use a hand cart when moving the instrument. At least
two persons are necessary to lift the instrument.
Failure due to dropping of the instrument, back
injury, or stumbling may occur.
• Be sure to lift the instrument by holding it at the points
, , , and at the bottom of both sides
(see the figure to the right). Do not lift the instrument
by its cover.
Failure to do so may cause the instrument to fall
resulting in injury or malfunction.
• Be careful not to get fingers caught when setting the
instrument down.
Fingers may get caught between the table and instrument resulting in injury.
• Set the instrument on a table whose area is larger (50 mm or more) than the outer dimensions of the
instrument as shown below. A table height of 650 to 700 mm is recommended to allow space for the
pump tank to be installed under the table. Additionally, the table must be sturdy enough to bear the
weight of the instrument (33 kg) and be provided with adjusters on its legs to allow it to be level and
stable.
Failure to do so could cause the instrument to fall in the event of impact or accidents.
An opening must be made in the table to pass the pipe through.
• Install the instrument in a stable and level place where vibration or shock does not occur.
Tilting or vibration can cause the instrument to fall or prevent normal lens processing.

FOR SAFE INSTALLATION: During Installation
CAUTION
• Only personnel authorized by NIDEK or a NIDEK distributor are allowed to install the instrument.
• Install the instrument in an environment that meets the following conditions.
The following conditions must be maintained during use.
•Use conditions
Temperature: 5 to 40°C (41 to 104°F)
Humidity: 30 to 80% (5 to 31°C [41 to 87.8°F])
The minimum acceptable relative humidity is 30%. The maximum acceptable relative humidity is
80% for temperatures up to 31°C (87.8°F) which decreases linearly to 50% at 40°C (104°F).
Altitude: Up to 2,000 m
Installation location: Interior (with low dust and free from smoke, vibration, and impact)
• Be sure to wear protective gloves when using a utility knife during unpacking.
Contact by bare hands with a utility knife or sharp edge of cardboard may result in injury.
• Install the instrument on a table with a height and depth that allows comfortable operation.
Continued use in an awkward posture may result in back strain.
• Do not block the cooling fan on the rear of the instrument.
Should the fan be blocked, a rise in temperature inside the instrument may occur resulting in fire.
• Avoid installing the instrument where it is exposed to caustic material such as corrosive gas, acid, or
salt.
Corrosion or malfunction may occur.
• Do not use a power cord other than that supplied. Also do not connect the supplied cord to any other
instrument.
Malfunction or fire may result.
• Do not overload the electrical outlet.
A multi-outlet supplying power to too many instruments may become overheated and cause fire.
• Install the instrument in an area where the outlet that the power plug is inserted into is easily acces-
sible during use. In addition, ensure that the power cord can be disconnected without the use of any
tool.
Failure to do so may interfere with disconnecting of the power from the input power source in case of
abnormality.
• Be sure to use a wall outlet which meets the power specification requirements.
If the line voltage is too high or too low, the instrument may not perform properly. Malfunction or fire may
result.
• Completely insert the power plug into a grounded outlet as far as the prongs will go.
Electric shock or fire may result in the event of malfunction or power leakage.
• Do not place heavy objects on the power cord.
The damaged power cord may cause fire or electric shock.
• Check the connection of the feedwater and drain hoses before activating the instrument.
Electric shock due to water leakage or injury caused by a wet slippery floor may result.

FOR SAFE INSTALLATION: During Checking and Adjustment
1.4 During Checking and Adjustment
WARNING
• Never touch the wheel while it is rotating.
Injury may result.
• Never open the processing chamber cover during lens processing.
Spray containing processing waste may cause eye damage.
• Be sure to visually check that the wheels are not chipped or cracked before processing.
If chipped or cracked wheels are used, they may break or shatter resulting in injury.
• Do not inhale vapor on particles produced during lens processing. Wear a mask, glasses, and other
such protective gear.
Vapor or particles may be toxic depending on the materials.
CAUTION
• In the event of smoke or strange odors, immediately turn off the instrument and disconnect the
power plug from the wall outlet.
Use of the instrument under such abnormal conditions may cause fire or electric shock. In case of fire,
use a dry chemical (ABC) extinguisher to extinguish the fire.
• Immediately replace the power cord if its internal wires are exposed, power is intermittent when the
cord is moved, or the cord and/or plug are hot to the touch.
Electric shock or fire may occur.
• In the event of malfunction, disconnect the power cord from the wall outlet. Never touch the interior
of the instrument.
Electric shock or fire may occur.
• Be careful not to injure hands on any sharp edges when removing a processed lens.
The lens edge may cause finger injury.
• Safety bevel the front and rear surfaces of glass lenses after processing.
Subtle burrs may cause skin damage.
• Be careful not to get fingers caught when chucking (securing) a lens.
Injury may result.
• Protect the display from splashing water. Also, never operate the display with wet hands.
Water seeping into the instrument may result in electric shock, malfunction, or fire.
• Always clean up any spilled water from the pump tank with a clean dry cloth.
A slippery wet floor may cause injury.
