(1) Do not stop the supply air to the dampener while discharge piping is pressurized.
Otherwise the bellows may be deformed. Also, the pulsation reduction effect can not be received.
(2) Do not use the dampener at a higher pressure than the specified pressure of the pump.
The dampener may fail if it continuously operates exceeding the max. allowable liquid pressure and the max.
allowable supply air pressure. (Refer to 4. Specification)
(3) Do not handle the liquid which is apt to crystallize or contains slurry.
These liquids shorten the life of bellows.
(4) Pay attention to stripping agents or solvents.
• Some strippers may cause the cracks in a short time in the bellows or in piping (PFA material).
(Guarantee period is different for these liquids. Ask IWAKI.)
• Risk of fire. Do not connect the electrodes with any device including our controllers when using solvent.

(1) Connect tubes to Inlet and outlet of the dampener horizontally.
(2) Install the dampener between the pump and the filter, as close to the pump. Keep the tube length
between the dampener and the pump less than 1 meter.
(3) Keep a space around the dampener for maintenance work.
(4) Mount the dampener and the pump securely on a flat foundation.

WARNING
The temperature of the dampener or pipe surfaces becomes very high while a high tem-
perature liquid is pumped. Do not touch them with bare hands. Always wear protective
clothing.
WARNING
Do not connect the electrodes with any device including our controllers when using a sol-
vent. Solvents may catch fire due to a electric spark.
