Before operation
This section describes pump operation and programming.
Run the pump after plumbing and wiring are completed.
Before operation
Check a flow rate, tubing and wiring. And then perform degassing and flow rate
adjustment before starting operation.
Points to be checked
Before operation, check if...
• Liquid level in a supply tank is enough.
• Tubing is securely connected and is free from leakage and clogging.
• Discharge/suction valves are opened.
• A power voltage is in the allowable range.
•
Electrical wiring is correct and is free from the risk of short circuit and electri-
cal leakage.
Retightening of pump head fixing bolts
Important
The pump head fixing bolts may loosen when plastic parts creep due to tem-
perature change in storage or in transit, and this can lead to leakage. Be sure
to retighten the bolts evenly to 2.16N•m in diagonal order before starting opera-
tion.
*Tighten fixing bolts once every three months.
