5-1-5 Installation
Follow the procedure below to install modules.
C AUT IO N
Wear appropriate protective clothing including a helmet, a safety belt, safety shoes, and safety gloves.
Use appropriate tools for tightening and loosening bolts and nuts, and handle them with due care.
Assemble modules on a stable surface in order to prevent them from falling over.
Use a chain or similar to prevent modules from falling over.
Be very careful not to trap your fingers between the module and diffuser parts.
As the modules are very heavy, when using forklifts and cranes make sure that all apparatus is
inspected and certified, and all operators are certified.
Do not climb on the modules.
1. Receive and unload the modules.
Place module packages on a hard level floor not exposed to direct sunlight, humidity, rain, and
excessive temperatures. Never let them freeze.
2. Open the packages.
Open the packages of the modules. Be careful not to damage the membrane modules when
opening the packages.
3. Check the products.
Check that elements, element holders and element supporters have been correctly installed and
that there are no loose bolts etc.
4. Connect the air and filtered water hoses and the collecting pipe.
5. Lift and place the modules.
Lift modules and place them by lowering them along the guide pipe of the tank (See Figure 5-4).
Refer to "5-2 Procedures for Lifting up Module" (p.37).
6. Check that the modules are level.
Install modules in a location with horizontality of 3 mm/1,000 mm or less. Placing modules on a
surface which has a greater slope may result in uneven aeration and inadequate membrane
scouring and cause membrane clogging.
When installing several modules, ensure that the difference in height between the tops of the
modules is no more than 6 mm. If the difference is higher than this, diffusion between the modules
will not be uniform.
C AUT IO N
Take care as modified tanks may be sloped. Make sure that diffusers in the same group are
installed at the same height.
7. Connect pipes to modules.
Connect pipes (suction and diffuser pipes) to modules after installation preparation, confirmation
before installation, and steps 1 to 6 have been completed.
RE F ER E NC E
 Perform conditioning after installing the modules. (See p.39 "6-1 Commissioning")
