to the pipe from air supply unit with the flanges. The connection of the air diffuser has an
internal thread. There is one connection in the air diffuser of NHPA050/100 and two
connections in the air diffuser of the NHPA150. Prepare and use the fit hose nipples and
other parts to connect the air diffuser to the air supply line.
After plumbing in the air diffusers, fill the membrane tank with clean water until the aeration
blocks are completely submerged in the clean water. Next turn on the air supply, check to
make certain that the air is being evenly distributed throughout the aeration block.
(3) Installation of Element Blocks
Adjacent two (2) element-decks can be connected to comprise the element block by
bolts and nuts. If you apply riser pipe (see (2) in the page 27), relevant decks must be
connected.
Put the element block(s) onto the aeration blocks. Joint both using provided bolts if guide rail
system is not applied in case of -1F and -2F.
Use guide rails certainly and do not connect three (3) element-decks or more when
installing taller module NHPA150-3F and 4F. For 3F put one (1) upper element-deck
onto the lower element block which consists of two (2) bolted element-decks. For 4F
put the upper element block which consists of two (2) bolted element-decks onto the
lower element block which consists of two (2) bolted element-decks.
Also, do not lift and install entire decks at one time. Upper/lower element block must
be installed one by one to avoid distortion or damage to the element block which may
cause severe accident.
The serial number of each aeration block and its position in the tank should be recorded.
After installation,
take adequate measures to protect the elements and other
components from damage by covering with fireproof tarps.
