5-1-2 Notes Regarding Storage
 Store the products indoors in a dry condition and avoid exposure to rain and wind.
Do not let unused elements become damp, as storing damp elements for a long period of time may
cause mold growth and a decline in permeability.
 Store elements and modules in a temperature range of 5 to 40°C.
 Store the products on a level surface to prevent them from falling over.
 If insects, mice, or other small creatures enter any of the products they may cause product damage.
Avoid storing products in a place where small animals or insects may enter the products, and take
measures to prevent them from entering the products.
5-1-3 Points to Consider When Preparing for Installation (Cleaning)
 Before installing modules, inspect the inside of pipes and removes foreign matter. Keep the inside of
pipes, tanks, and pumps clean during installation work. Remove foreign matter and residue from
installation work by cleaning them after the work is finished and by flushing pipes at the design flow
rate. Then inspect the devices and equipment before starting operation. Perform cleaning and
inspection similarly for raw water pumps, permeate pumps, blowers, and pipes used for chemicals.
 Remove any foreign matter larger than the openings of extra fine screens (0.5 to 1 mm) found along
the filtration line between the extra fine screen and the membrane tank.
 Cover cleaned tanks with a cover or plastic sheet so that foreign matter cannot enter them.
 Do not let any matter that will damage the membrane tank or that is 1 mm or greater (see below) at
any time, including during installation work. If foreign matter is mixed in, it can damage the membrane.
■Examples of foreign matter that can damage membranes
 Water containing foreign matter larger than the screen openings
 Foreign matter which is blown into or falls into the module during maintenance and repair of the
upper part of the module (fallen leaves, plastic bags, etc.)
 Residue from pipes and devices
 Any other things such as:
tying bands, wire bands, bolts and nuts, rulers, wires and wire fragments, drilling waste, tape
fragments, welding slag, grinding waste, small branches, leaves, fish, etc.
WAR NI NG
Be sure to remove all foreign matter as it will shorten the lifespan of the membrane.
