(9)Countermeasures against static electricity
Since static electricity may be generated depending on the fluid being used, implement suitable
countermeasures.
(10)The pump cannot transfer gas. Do not allow it to idle for a long time.
If the pump is operated for a long time without any fluid inside, the diaphragm may be damaged or
the life may be shortened. Do not continue idling longer than 3 minutes.
(11)Pilot port condensation and freezing
Condensation may form in the piping of the AIR SUP port, due to sudden cooling because of the
expansion of supply air. The fluid may freeze in winter. Measures should be taken so that the
electrical parts and equipment do not get wet due to dripping.
Caution
(1)Operation stop of the pump
When the operation of the pump is stopped, be sure to exhaust the residual pressure in the pump.
When operating this pump, please use a 3-port normally closed (N.C.) solenoid valve to
completely exhaust the residual pressure.
(2) Slurry cannot be transferred.
Slurry cannot be transferred due to seating failure and wearing of the check valve and
accumulation of particles causing operation failure.
2. Precautions for installation
Warning
(1)Use clean air.
1. Do not use compressed air which contains chemicals, synthetic oils containing organic
solvents, salts or corrosive gases, etc., as this can cause damage or malfunction.
2. The quality of the compressed air used should correspond to system No. C to F in Best
Pneumatics (5)(P.2 to 3).
(Install a filter with filtration accuracy of 5

m. If necessary, install a mist separator with the filter.)
3. Supply air which has been dried by an air dryer.
(Recommended atmospheric dew point is -10
o
C or less.)
4. Supply air in the range of 0.2 to 0.5MPa with sufficient supply capacity.
(2)When the process pump is used under low temperature, beware of freezing.
The equipment operates by expanding compressed air. During adiabatic expansion, the temperature
inside of the product goes down. When the ambient temperature is low, heat cannot be obtained from
the surrounding environment. Freezing can result if compressed air containing moisture is used. In
this case, the membrane air dryer (IDG etc.) is recommended to prevent freezing.
