4. PREPARATIONS BEFORE INSTALLATION

(1)

Position of suspension bolts on the BS unit.

BSVQ36 · 60MVJU

(2)

Install suspension bolts.

Use M8-M10 suspension bolts.

When holes are to be made anew, use 

inserts or anchor bolts.

When holes are already provided, use hole-

in anchors or the like.

Install the BS unit so that its weight can be 

withstood.

(3) Support the connection piping.

To prevent excessive weight from bearing on the hunger brackets of the BS unit, support the connection 
piping around the unit and no further away than 40’’ from the unit.
Too much weight on the hunger brackets will cause the BS unit to drop and cause injury.

5. BS UNIT INSTALLATION

(1)

Attach the hunger brackets to the suspension bolts.
Be sure to sandwich the hunger brackets between nuts and washers, and 
securely fix it.

Caution

The BS unit has a top and a bottom, so install it so that the diagonal lines in the figure next page are where 
the top is.
(Failing to do so may prevent the unit from operating properly and increase the volume of the operating 
noise.)

(2)

The electric parts box may be installed on either side of the BS unit, as shown below.
1. Remove the electric parts box lid. (2 screws)
2. Remove the top panel. (4 screws)
3. Remove the electric parts box. (2 screws)
4. Change the way the wiring between the unit and the electric parts box (transformer, two solenoid valve 

coils) is pulled out. (See the figure at next page.)

5. Attach the electric parts box.
6. Turn the top panel around 180° and attach it.
7. Attach the electric parts box lid.
