V. INSTALLATION OF “NHPA SERIES”
1. Preparatory Procedure
(1) Take precautions to plan the route for the “NHPA Series” to the membrane tank.
The route should include the unloading area for the “NHPA Series” to the final
installation site.
(2) Make arrangements of the necessary equipment to unload the “NHPA Series” from
a truck such as a forklift, pallet jack, etc.
(3)
Prior to installation, confirm that all necessary piping components are in
place within the membrane tank. Make certain that all construction waste
materials have been removed from the tank.
All loose materials remaining in the
tank should be removed from the tank prior to installation of the “NHPA Series”.
In
addition, it is important to test all water and air lines to confirm that all field
assembled joints are free of leaks.
2. Unloading/Lifting Products
Unload "NHPA Series” with suitable equipment such as forklift, crane, or truck mounted
hydraulic lift gate.
Inspect the "NHPA Series" module for any damage inflicted during transport.
(1) You will receive two packages with the “NHPA Series” module. One is the element
block complete with the prescribed number of membrane elements and the other
box an aeration block.
(2) Do not lift the packages from overhead when unloading the package which
contains multiple element blocks or aeration blocks. Always lift these packages
from underneath using a forklift or pallet jack.
(3) To avoid damage, do not stand or sit on the packages.
(4) A cassette can be handled by manpower only before starting operation. If several
cassettes are installed in an element block frame, do not move it by hand and use
appropriate equipment such as a forklift.
(5) Use the lifting brackets on the module to connect to the lifting device when lifting
"NHPA Series" (or lifting element block/aeration block separately) after unpacking.
Take precautions to keep the “NHPA Series” components upright in their proper
orientation.
(6) Be careful not to damage element nozzles, air diffusers, filtrate manifolds, or
other components when lifting.
(7) Employ good safety practices when unloading the “NHPA Series” components.
Attach chains or slings to the lifting lugs when lifting “NHPA
Series”. Slowly raise the module straight up. Avoid sudden
changes in movement to minimize shaking the module. Never
allow personnel to stand under the “NHPA Series” during lifting
