EHN- [11•21] [FC] and [31•36] [VC•VH•PC•PH•PP•FC]
The air vent port is not provided to the EHN-31•36 and the FC types.
Install an air vent valve on the discharge line for degassing. See page 23 for
detail. Follow the procedure below to conduct degassing if the air vent valve is
not available.
Connect a discharge tube and place
the tube end in the supply tank or
another container.
* Remove the check valve from the dis-
charge tube if it is installed.
* When resuming the pump operation after
liquid replacement in the supply tank or
after a long period of stoppage, the inter-
nal pressure may remain in the pump or
tubing. Removing the check valve at this
state, liquid may gush out. Wrap a waste
cloth around the check valve connection
for the prevention of gushing.
Turn on power.
The LED lights and a display related to the
current mode appears on the screen.
* The pump enters the wait state in the manual
mode when turning on power with a default
setting. The pump calls up the last screen at a
shutoff if it was not in a default setting.
