sure not to install it upside-down.
2. There are no scratches on the wiring inside the
unit body!
3. The unit body, fans, nuts, and front panel all have
been mounted securely.
4. Switch power on and confirm that the Air Curtain
operates correctly.
CAUTIONS
This applies to mishandling or misoperation of
the product which will lead to injury or damage
to your home, household effects, etc.
¡
Do not hang on the product or swing from it.
(It may fall, resulting in injury.)
¡ Use Single-phase 220~240 V, 50 Hz power supply. (If the wrong power supply is used, it could cause a fire or electric shock.)
¡ 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.
(Poor connections or errors in the wiring work could result in electrical shock or fire.)
¡ During installation and maintenance, always wear gloves. (If gloves are not worn, your hands could be injured.)
¡ 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.)
¡ Never use the product in a bathroom or other location with excessive moisture (more than 90% RH).
(Electrical shock or fire may be caused.)
Notes
¡ The digits in the model number indicate the standard barrier distance and installation width. (In the case of the GK-3509SA, the standard barrier
distance is 3.5 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 outflow 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.
¡ 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.
¡ The appliance is not intended for use by young children or infirm persons without supervision.
¡ Young children should be supervised to ensure that they do not play with the appliance.
Description of Functions
¡ The unit is equipped with a 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 and capacitors.
Also, if the portion of the unit where the motors are mounted has become malformed or is otherwise abnormal, the mounting should be
replaced as well. Contact a specialist installation contractor to perform the replacement.

Mounting Method
Mounting locations and surfaces differ, but in any case make sure that the unit is mounted sufficiently securely and that it is level.
<
NOTE
>
¡ In the case of a standard installation (with the unit mounted horizontally), install it so that the air outlet is facing downward.
¡ If there is a wall on the side of the air curtain, install the wall mounting plate 40 mm or more from the wall. Otherwise, the air curtain’s
body will hit the side wall and you will not be able to install it.
¡ If multiple units are being installed continuously, install the mounting plates at an interval of 80~95 mm from each other.
¡ If you are mounting the air curtain on a wall, leave a gap of 55 mm or more from the ceiling to the mounting plate. If it is closer than
that, the unit will hit against the ceiling and you will not be able to install it.

them securely.
If the panel thickness is 20 mm or greater,
mount the wall mounting plate directly on
the wall with the washers and spring
washers supplied with the air curtain, and
wood screws (supplied by the customer).
If the panel thickness is less than 20 mm,
install a reinforcing board (supplied by the
customer) so that the total thickness
becomes 20 mm or greater.
(1) Installation holes have already been made in the
wall mounting plate’s mounting hole positions.
(2) Install the wall mounting plate on the wall
using the washers, spring washers and nuts
supplied with the air curtain and bolts (supplied
by the customer), fastening it securely.
¡ Install the mounting bolts so that they
protrude from the wall mounting plate about
15 mm.
Remove the two mounting screws from the unit body, then
remove the wall mounting plate from the unit body.
