Degassing
The gas in the pump and tubing is the obstacle to liquid delivery and needs to be expelled before the pump is
started. Especially:
• 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 are performed
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 damage skin and dry end parts. Wash/wipe chemicals off immediately if they got wet.
Points to be checked
• An air bleed tube is connected to the pump.
Turn on power.
The ON LED and the display are turned on.
