Caution
Prohibited use
Do not use the pump with other than as listed on the pump specifications or nameplate. Especially, check
the motor
’s power supply specifications (phase, voltage, and frequency) before connecting. Incorrect
usage may cause a physical injury or damage of the filter pump or peripheral devices.
Restriction on users
Only knowledgeable experts of the pumps should handle
and perform installation, wiring, operation, or
maintenance.
Cautions on unpacking
Check and confirm the proper side up when unpacking. When unpacking the crate, be careful with nails or
wood chips to avoid any injury.
Ventilation
If any object is placed around the pump, it can block ventilation, causing the motor to overheat.
When handling poisonous or odorous liquid, install the pump where sufficient ventilation is available, due
to risk of inhalation.
Repair and return
To request repair of a damaged pump, contact our sales representatives or your distributor.
When returning the pump using a carrier service or parcel delivery service, wash both inside and outside
of the pump with clean water, make sure no liquid residue is left, and wrap it with a plastic bag.
Resin parts
The pump consists of resin parts, so a strong impact may damage parts or lead to physical injury. Do not
strike the pump with any objects or climb on it. Additionally, install a pipe support to prevent a load being
directly applied to the pump.
Starting of the pump
Make sure to check the rotational direction when starting the pump for the first time. Open the suction and
discharge valves and ensure no liquid leakage near the pipe connection area. After air is released from
the pipes and liquid is filled within the pump, briefly start to check the rotational direction. If the direction is
reversed, in the three-phase power supply, switch two of the three cables. As a precaution, ensure the
power supply is disconnected before performing any work.
Disposal of the pump
When discarding used pumps, dispose of them as industrial waste following the applicable laws and
regulations after removing accumulated chemicals.
