WARNING
CAUTION
• Never use the product in a bathroom or other location with
excessive moisture (more than 90% RH).
(Electrical shock or fire may be caused.)
• When installing the main unit, select a location which is sufficiently
strong, and install the unit securely.
(Failure to do so may result in the unit falling, resulting in injury.)
• Install the parts properly and securely.
(Failure to do so may result in the parts falling, resulting in injury.)
• Wiring work should be performed safely and reliably, and in
accordance with applicable electrical equipment technical
standards and internal wiring standards.
(Poor connections or errors in the wiring work could result in electrical
shock or fire.)
• If more than one unit is to be operated at the same time, ensure that
the combined current vaiue fiowing through the terminal panel to
which the units are connected does not exceed 5A. (Failure to observe
this precaution could result in electrical shock or fire.)
• If the product is not going to be used for a prolonged period of time,
be absolutely sure to set the circuit-breaker on the power board to
the OFF position.
(Deterioration in the insulation may cause electrical shock, power leaks or fire.)
Notes
• The digits in the model number indicate the standard barrier distance and installation width. (In the
case of the GK-2509YS1, the standard barrier distance is 2.5 m and the installation width is 90 cm.)
The Air Curtain will not be effective if the air flow is too weak or if it is too strong. Make sure to
confirm the installation height and the model.
• When installing the Air Curtain at the entrance to a store or office, the air outlet opening should be
oriented toward the inside. However, it may be oriented toward the outside provided that the unit is
installed under eaves or an awning that prevents rain from falling on it and there is no danger of rain
being sucked into the intake opening. Also, the unit must be installed outside if it is to be mounted on
a freezer room.
• If the unit will be recessed in the ceiling, be sure to provide an inspection opening (with an opening
at least 450 mm wide) in the ceiling to allow for maintenance inspections.
• Should a power failure occur, be sure to turn the unit’s power switch off. (Otherwise, there is a danger
that a malfunction could occur if the unit’s fan suddenly starts to turn when power is restored.)
• Use a motor circuit breaker or the like with the wiring system.
Description of Functions
• The unit is equipped with overheating prevention device (thermal fuse) to prevent overheating of the motors and resistors. During abnormal conditions, such as if the ambient temperature is unusually high, if an
overload occurs, if a phase interruption occurs during operation, or if operation is restricted in some way, the fuse will burn out, preventing power from being supplied to the unit. Should this occur, the unit cannot
be restarted. Should the power be cut off while the unit is operating, perform the steps below before restarting the unit.
Treatment:
It is necessary to switch off the power supply, remedy the cause of the problem, and replace the motors, capacitors, and resistors. (The GK-2509YS1 1and GK-3009AS have two different types of motors. Take care
to replace the motors with the correct type.)
Also, if the portion of the unit where the motors and resistors are mounted has become malformed or is otherwise abnomal, the mounting should be replaced as well. Contact a specialist contractor to perform the
replacement.
WARNINGS
Be sure to hand over these Operating and Installation Instructions to the user when the installation work has been completed.
• Do not touch the moving parts.
(You may injure yourself.)
• Do not poke your fingers or any objects into the air outlet openings
or moving parts during operation since this is dangerous.
(You may injure yourself.)
• If operation stops while the power is still switched on, do not touch
the product under any circumstances.
(There is a danger that the unit could suddenly start operating again and
cause injury. There is also a danger of electrical shock.)
• DO not attempt remodelling under any circumstances. Disassembly
and repair are permitted only by qualified repair engineers.
(The product may cause fire, electrical shock and/or injury.)
For repairs, please contact the dealer from whom the unit was
purchased or a Mitsubishi Electric Corporation customer service
center.
• Do not apply water to the product or splash water onto it.
(Short-circuiting or electrical shock may be caused.)
• Do not use the product where the combustion area of its combustion
device will be directly exposed to wind or air movement.
(This may cause incomplete combustion or result in the flames being
extinguished leading to carbon monoxide poisoning.)
• When passing the product and metal ducts connected to the product
through wooden buildings lined or covered with metal or wire laths
or with metal sheets, install the product and ducts in such a way that
they will not make electrical contact with the metal or wire laths or
metal sheets.
(Ignition may occur if there are power leaks.)
• Before proceeding with maintenance work, be absolutely sure to set
the circuit-breaker on the power board to the OFF position. In
addition, do not perform the work with wet hands. (Electrical shock
or injury may result.)
• Ground the product properly.
(Electrical shock may be caused in case of malfunctioning or power
leaks.)
• Do not use this product outside its rated voltage and power line
frequency ranges. (Fire or electrical shock may be caused.)
• Do not hang on the product or swing from it. (It may fall, resulting in
injury.)
CAUTIONS
The Air Curtain should be cleaned when it gets dirty — roughly once every
three months as a general rule. Also, be sure to clean and test run the Air Curtain
before starting operation for the summer and winter seasons.
• Always switch power off before cleaning the unit.
• Never hang from the unit or push downward on it forcefully. A serious
accident could result.
• Wear rubber gloves to avoid injuring your fingers.
Speed Adjustment and Angle Adjustment
If the wind outside affects the effectiveness of the Air Curtain, the following
speed adjustments and angle adjustments are possible.
Make wiring connections for the parts indicated by black lines in the connection

unit, guards, fans and ducts. Then wipe with a dry cloth to remove any
remaining detergent.
Note
• Do not use solvents such as the following to clean the unit:
Paint thinner, alcohol, benzine, gasoline, kerosene, aerosol sprays, alkaline
solvents or chemicals in chemically treated cleaning clothes. (Surface
deterioration or discoloration could result.)
