FOR SAFE OPERATION OF “NHPA SERIES”
Before using “NHPA Series”, please thoroughly read this Instruction Manual and follow the
instructions described in this manual, especially the safety precautions shown below. The
details of each precaution are described in the relevant chapter
1. Safety Instruction for Unpacking and Installation
Attach chains or slings to the lifting lugs when lifting element-deck, an
element block or aeration block of “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.
Never lift or operate the module with worn or damaged parts. Use chains or
slings rated for the weight being lifted. Check the condition of each part
before lifting.
Do not lift upper element blocks and lower element blocks at once as one
unit when lifting NHPA150-3F or 4F. Lift the upper and lower element block
separately.
Make provisions, in advance, to access the upper portions of the membrane
module via a scaffold or ladder when installing “NHPA Series” module. Do
not climb on the module structure. Never step on the air diffuser and filtrate
water manifold. Use protective equipment to ensure the safety of workers.
Wear the appropriate personal protective equipment (e.g. safety gloves) in
order not to cut one’s hand on the edge of the module frame.
During transportation, storage, and installation, take appropriate measures
to protect "NHPA Series" or associated components from damage. Do not
put any heavy objects directly on the module. Store the module in an area
that will minimize the risk of damage from moving equipment like forklifts etc.
Exposing the “NHPA Series” and membrane elements to temperatures
above 40 deg C or direct sunlight should be avoided. Exposure to direct
sunlight/UV radiation will cause the polypropylene filtrate water manifold to
deteriorate.
