¡When a tightening valve is located on the discharge piping, and when there is a risk of blockage, be sure to
install a relief valve on the piping immediately on the discharge side of this pump. When a valve has been
tightened or foreign matter clogs the discharge piping of the pump, the pressure in the pump may increase
beyond the range indicated in the pump specifications. This may result in chemicals spurting out, damage to the
piping or malfunction of the pump, which are dangerous.
¡To prevent chemical leakage from the relief valve return piping, return the tip of the piping to a tank or other
receptacle.
¡This pump is made to outdoor specifications. It is, however, made of plastic so try to avoid installing it at
locations that will shorten its life (e.g. where it is exposed to direct sunlight or wind and rain).
¡When using water-diluted solutions in cold areas, chemicals may freeze in the pump head or piping, damaging
the pump and peripheral parts. Be sure to install heating apparatus or heat insulation.
¡Water used in the pre-shipment test may remain on pump liquid-end parts. When using chemicals that generate
gas or harden due to reaction with water, be sure to drain any water and allow liquid-end parts to dry before use.
¡Generally, the pressure-resistant performance of hoses is impaired when they become hot. When using
commercially available hoses, be sure to use hoses that can resist the operating temperature and pressure as
well as being resistant to chemicals. Otherwise, the hoses may become damaged or chemicals may spray from
the piping.
¡The durability of hoses varies considerably depending on the chemical used, temperature, pressure, and UV
rays. Inspect the piping, and replace it if it has deteriorated.
¡Do not apply excessive force on the cover as it is made of plastic. Doing so might damage the cover.
Electrical Wiring
¡Do not operate this pump with wet hands. Doing so might result in electric shock.
¡Do not turn the power ON during electrical wiring. Attach a "Work In Progress" label to the power switch.
¡Reliably ground the ground terminal. Failure to do so might cause electric shock. Be sure to install a current
leakage breaker.
¡Do not disassemble the body or circuits.
¡Electrical wiring must be performed by personnel such as an electrician having specialist knowledge.
¡Check the power voltage before wiring. Do not wire a power supply outside of the rated voltage range.
¡Be sure to ground the earth lead (green-yellow) when wiring to prevent electric shock.
! CAUTION
! WARNING
Operation and Maintenance
¡Only the operator or administrator is allowed to operate this pump.
¡Do not operate this pump with wet hands. Doing so might result in electric shock.
¡If anything unusual occurs such as smoke or a burning smell during operation, immediately stop operation and
contact your supplying agent. Failure to do so might result in fire, electric shock or damage to the product.
¡Do not disassemble the body or circuits.
¡During air release, chemicals spray forcefully from the tip of the piping. Either release air using water or other
safe liquid, or return the tip of the air release piping to the tank. During this operation, either hold the air release
hose by hand or secure it in position.
¡When a valve has been tightened or foreign matter clogs the discharge piping of the pump, the pressure in the
pump may increase beyond the range indicated in the pump specifications. This may result in chemicals
spurting out, damage to the piping or malfunction of the pump, which are dangerous. Check the valves before
the operation.
¡Before disassembling liquid end parts for maintenance or repair, be sure to turn the power OFF and make sure
that no voltage is being applied to the pump.
¡Do not turn the power ON during electrical wiring. Attach a "Work In Progress" label to the power switch.
¡When handling liquid-end sections, be sure to wear protective coverings (rubber gloves, mask, protective
goggles, chemical-resistant overalls, etc.) appropriate for the chemicals be using used.
¡Before maintaining or repairing the pump, be sure to release the discharge-side pressure, drain the chemicals
from liquid-end sections, and wash the pump with water.
¡Pump vibration sometimes causes hoses to become loose and disconnected. Before starting operation, make
sure that tubes are secured in position and tightened.
¡During operation, the surface of the pump sometimes reaches or exceeds 60°C. When touching the pump during
operation, be sure to wear protective coverings that can resist high temperatures.
¡Idling the pump for a long time may cause the pump to malfunction. Do not idle the pump for more than one
hour.
