Before operation
■ Use of hexagon wrench instead of a torque wrench
Fasten the fixing bolts as tight as can be by the hand with the straight long part
of a hexagon wrench (a) and further turn the bolts clockwise 90 degrees with
the short part (b).
Degassing
The gas needs to be expelled from the pump and tubing by degassing. Normal
performance can not be obtained with gas in the pump. Conduct degassing in
the following cases.
• When the pump starts to run for the first time
• When a flow rate is too low
• After liquid is replaced in a supply tank
• After a long period of stoppage
• After maintenance and inspection
NOTE
• Both gas and chemical come out together through an air bleed tube. Place the end of
the tube in a supply tank or a container.
• Some chemicals may cause skin trouble or damage component parts. When your
hand or component parts get wet with chemical liquid, wipe off immediately.
