PARTS DESCRIPTION
TYPE SELECTION METHOD, MOUNTING DIMENSIONS
TYPE SELECTION METHOD
- Select the suitable type of this mechanism depending on the weight of the applicable door (including the handle weight) as per Table 1.
- Measurements of cabinet door should be considered to select a proper type of model HBFN mechanism. ( Fig.2 )
- The dimensions as cabinet height (H 0) and cabinet door height (H 1) should meet within the specification of following formula.
- Cabinet Height (H 0)=Door Height (H 1)x2+{ (Top board thickness-Overlay)+(2mm gap between upper door and lower door)+(Bottom board thickness Overlay)}
- The dimensions of an upper door and a lower door should be the same ones. Cabinet Door Width (W 1) : 450~900mm
- Cabinet Door Thickness (T 1) : 17~20mm ( Refer to Fig. 2 )
- The concealed hinge (overlay use) should be used as a door-hanging device. The LAMP brand 220 series concealed hinge (product No.220-26/19T or No.220-C26/19T) is recommended.
- Contact our sales representatives in case of installing to a cabinet exceeding the indicated ranges.

HOW TO ADJUST THE ARM LENGTH, INSTALLATION PROCEDURE
HOW TO ADJUST THE ARM LENGTH
-
Step 1.Using hexagon key (2.5mm) loosen the screw in the center of adjustable dial on the side-face of arm. ( Fig. 4 )
-
Step 2 Using hexagon key (8.0mm) set the adjustable dial at “Free” position. ( Fig. 5 )
-
Step 3 With setting the adjustable dial at “Free” position, adjust the arm length. ( Fig. 6 & Table 2 )
Arm length adjustment is done by to set the marked line (number 1-6) shown on the side-face of the top arm to the edge of the bottom arm. -
Step 4 Using a hexagon key (8.0mm) set the adjustable dial at “Lock” position. ( Fig. 5 )
-
Step 5 Using hexagon key (2.5mm) tighten the screw in the center of adjustable dial on the side-face of arm. ( Fig. 4 )
Notice: Turn the adjustable dial excessively with setting the arm adjustable position incorrect or improper may cause the unit broken. After arm adjusting, set the adjustable dial at “Lock” position and fix it by hexagon keys.
INSTALLATION PROCEDURE
Installation of HBFN unit body
- Step 6.Set the unit body 1 (or 2 ) with the arm length adjusted according to the door height into the specified position on the inside surface of the cabinet(as for the mounting dimensions refer to Fig. 3 & Table 2 ), and fi x the unit body 1 (or 2 ) with the attached bind tapping screws 3.5×15 3 .( Fig. 7 )
- Step 7. Pull down the arm to the arrow direction completely. ( Fig. 7 )
Notice: In this step, do not release your hand from the mechanism during turning its arm. It may cause injury. Be careful not to insert your fi ngers into the arm mechanism when turning it.
Installation of mounting plate HBFN-SZ and off-set hinge
- Step 8. Fix the HBFN-SZ mounting plates 7 tightly and place the rubber bumpers 8 to the specified position of the back of the lower door with the attached bind tapping screw 3.5×25 9 . ( Fig. 8 )
- Step 9. The off-set hinges 4 should be used for the connection of the upper door and the lower door. The installing position of the off-set hinges should be set the hinge center at the lower door side.
( Fig. 8 )
Notice: The fixing screws for the offset hinge are not supplied in this package. Prepare 8 pcs. of them separately ( M3.5-M4 truss screw is recommended ).
INSTALLATION OF THE DOORS TO CABINET

In case of easy attachable concealed hinges, make sure that the concealed hinge could connect with its mounting plate fi rmly. Place the arm top hole into the axis of HBFN-SZ mounting plate 7 . Fix the both of arm (right-side and left side) to the HBFN-SZ mounting plates with the attached truss screws M4 x 6 10 tightly.
Step11. The HBF-SZ mounting plates have vertical adjustable function in the range of ±5mm, so that the arm mechanical movement can be tweaked for more proper door closing movement even after the installation.
( Fig. 10 )
Notice: In case using this adjustment function, tighten the adjustable screw of the HBFN-SZ mounting plates after all procedures.
ADJUSTMENT OF DOOR CLOSING SPEED
- Step 12.
Adjust the door closing speed with the speed-adjusting screw of the body backside. Speed adjustment is carried out with the 5mm Hexagon key. ( Fig.11 )
