Caution
Be sure to confirm the operations of the Contacts. If the confirmation is not
properly carried out, any unexpected operation of the Device may cause an
accident resulting in physical injury or a malfunction of the Product.
Refer to Section 5.5 “Wiring” for confirmation of operation to ensure that the
Product operates normally. Incorrect polarity setting of the power supply
may cause a malfunction of the Product.
④After the Contact setting is completed, be sure to seal the window for NO
(Contact A) / NC (Contact B) Contact Selector Switch, using the Contact
Switch Protection Seal supplied with the Product.
Caution
If the Louver is removed, the Discharge Needle will be exposed. Be especially
careful not to touch the Needle, or else you may get injured. Also, if the Needle
should be bent or be broken, the optimum performance of the Unit cannot be
expected. In case the Needle is bent or damaged, replace it with a new set of
Discharge Needle DTRY-ZEM-F04 (consumable item: separately available).
③
Prepare the new Louver to replace the old one. While firmly holding the
Main Unit in position, insert the new Louver from the lower side of the Main
Unit and push it upward until the 4 claws on the Main Unit engage with the
receptacles on the Louver. Confirm that they are mutually engaged, and
then push the Finger Grip at the top of the Louver downward until it clicks in
place.

5.2 Selection of Louver
As accessory items, this Product is shipped out with 2 types of Louvers: Direct
Air Advance (attached as standard before shipment) and Wide Angle Louver
types. Select the type most appropriate and efficient for the area from which
you are intending to eliminate the static electricity.
<Feature of the Direct Air Advance Louver>
This Louver is designed to allow the air to advance directly forward.
the Product to powerfully eliminate the static
electricity immediately in front of Product.
<Feature of the Wide Angle Louver>
This Louver permits the air to spread over a
wide area to eliminate the static electricity
there. Because the air spreads over a wide
area, however, this Louver somewhat
reduces the overall static elimination
effect of the Product.
