■ Pipe Flange Kits
Pipe flange kits are available. When ordering, specify the kit number from the table below.
★1. In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of
the flanges. Therefore, please pay cautious attension to the operating pressure when the socket welding flanges are used.
★2. Discharge port for pump model "A16" and "A22" is available only the threaded connections.
● Details of the pipe flange kits are shown on page 262.

■ Instructions
● Bleeding Air
In order to get steadily controlled pressure and flow, bleed air by loosening the air vent screw and fill solenoid armature with
operating oil.
● Manual Adjustment Screws
Manual adjustment screws may be used for initial running adjustment or in case of electrical failures in order to adjust pressure
and flow temporarily. In case of normal use, put the manual adjustment screws back in their preset positions.
● Position of Cable Departure
Position of cable departure can be changed. For details, refer to drawing below.
● Connection of Surge Cut-off Valve to "A" Series Pump (For A16 to A56 Type)
If using surge cut-off valve (SF1105-A-10), connect between pilot port "PP" of this pump and port "PP" of surge cut-off valve as
pilot piping (refer to symbol below).
Inside diameter of pipe should be more than 8 mm.
Consult Yuken of detail of surge cut-off valve.
