Points to be observed
Observe the following points during wiring work.
•
Electrical work should be performed by a qualified electrician. Always observe applica-
ble codes or regulations.
•
Do not perform wiring work while the power is on. Otherwise, an electrical shock or
short circuit may result. Be sure to turn off power before wiring work.
•
Be careful for the power not to be turned on during work.
NOTE
Do not hold the pump head to lift the pump unit up, or the pump head may deform and a leak may result.
Installation
Observe the following points during installation.
● Installation location
Mount the pump indoors. Allow sufficient space around the pump for easy access and maintenance.
● Mounting position
Install the pump as close to a supply tank as possible in a flooded suction system.
● Mounting direction
Always direct the outlet upward. Keep the pump head in a vertical position with the check valves upright.
Otherwise, performance may be reduced.
● Anchoring
Fix the pump with four M4 mounting screws (with PW and SW).
Piping
Observe the following points during pipework.
● Pipe connection
Both inlet and outlet of the pump have PFA tube joints. Secure every joint properly to eliminate any possibility
of air ingress, or performance may be reduced.
● Fitting and tube
Take account of corrosion and pressure resistance when selecting fittings and tubes.
● Pipe resistance
Keep a piping length shortest with the minimum number of bends.
