Safety Instruction for Filtration Operation 

Flush all the piping out with clean water and make sure no debris is 
remaining in the piping prior to connecting the modules. 

Confirm  that  the  preservative  chemical  in  the  modules  is  completely 
drained out  before starting the filtration operation.    The preservative 
chemical is harmful to humans. 

Flush the modules at low pressure, filling from the bottom, and vent to 
remove any air from the modules.    Air left in the modules may cause 
water hammer and may result in damage to the membrane. 

Prior to use, make certain modules are flushed.    Filtrate water should 
be drained unless it meets the required quality.   

Protect modules from direct  sunlight and ultraviolet  light.    Ultraviolet 
light can degrade module housing and membranes. 

Constantly  monitor  filtrate  water  quality  such  as  turbidity  and/or  the 
number of particles during filtration, and stop the operation if abnormal 
water quality is detected.
