the former section. Then, take the following steps to replace the air diffuser. Bolt size is M10.
TMR090-050S has one header pipe and TMR090-100S has two header pipes.
TMR090-100S has six air diffuser pipes with two different lengths.
The following figures show the case of TMR090-050S.
(1) Disjoint the header pipe from the
aeration block.
(2) Unscrew the air diffuser pipes from the
header pipe.
(3) Seal the nipples
of new air diffusers
with Teflon seal tape.
(4) Joint the new air diffusers to the header
pipes. Please use the pipe wrench to
tighten the joint (Don’t fasten tight by
grabbing the rubber part of the diffuser).
Please make sure that the surface of the
rubber part having no holes (slits) must
face upward or downward (The surface on
which stainless
clamps are fixed must face
upward or downward).
In case of TMR090-100S, since two
different lengths of the rubber diffusers are
to be handled, please take enough care to
joint air diffusers considering the position of
