We thank you for selecting IWAKI Auto-dampener PDA-W series. This instruction manual, which is divided into five sections of "Safety", "Outline of product", "Instal- lation", "Operation" and "Maintenance", deals with the correct handling and opera- tion procedures for the auto-dampener. To make maximum use and to ensure safe and long time operation of the auto-dampener, please read this manual thoroughly and carefully prior to operating the auto-dampener. -
Page 3: Safety Section
Important instruction For the Safe and Correct Handling of the Auto-dampener ● Before use of the auto-dampener, read this "Safety Section" to prevent accidents and to avoid the damage or loss of assets. ● Observe and abide by the instructions described in this "Safety Section". These instructions are very important for protecting pump users or other persons from hazard or loss of assets. - Page 4 Safety instruction WARNING ● Power off Be sure to turn off power prior to any inspection/maintenance and installation works. Be careful power is not turned on unintentionally while working on the dampener. In a noisy or dark place, display a sign Power off of "Men Working"...
- Page 5 Safety instruction CAUTION ● Countermeasure against static electricity When low electric conductivity liquid such as the ultra-pure water and the fluor inactive liquid (e.g. Fluorinert™) are handled, static electricity may generate in the pump, which may cause a static discharge and the pump breakage.

Page 13: Before Use
1. Before use (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. -
Page 14: Piping
3. Piping ■ Liquid piping Piping example (1) There is the distinction of suction and discharge Filter side tubes of dampener. Pay attention to the con- Pressure gauge nection. "I" is marked for suction side and "O" Discharge side (PG2) for discharge side. - Page 15 ■ Air piping CAUTION Use the instrument air which is dust free and dehumidified as supply air. If the supply air contains foreign matters, water, or oil, the pressure adjusting valves may malfunction and air may leak from the air exhaust port. (1) Air piping should be connected to the dampener on the discharge tube beyond the pressure reducing valve.

Page 17: Preparation For Operation
1. Preparation for operation When the pump is operated first time together with the dampener, check the followings. (1) Check to see if no damage, loosened bolts or leakage are found on dampener (pump). (2) Air pressure adjustment This auto-dampener automatically adjusts the air pressure to be sealed depending on handled liquid pressure, which requires no adjustment on the dampener. -
Page 18: Stopping
CAUTION Do not run the pump in time-lag operation. In the time-lag operation, the bellows of auto- dampener may fail in a short time. Also pulsation dampening effect can not be obtained. When the auto-dampener is used, the time-lag should be zero. Time-lag operation: When proximity switches detects the bellows movement and the switching-over signal is transferred to the solenoid valve, the switching-over signal is outputted with time lag. -
