7. Lifting Procedure
Please take the following steps to lift “TMR090 Series” modules for maintenance,
in the case that the modules are installed on the bottom of the tank with using anchors.
(1) Discharge completely activated sludge liquid from the tank.
(2) Remove the anchors.
(3) Disjoint the connection of the manifold and the air diffuser and lift the modules.
Please contact us beforehand if the modules are installed on the bottom of the membrane
submerged tank in the way other than using anchors.
When lifting “TMR090 Series”, please attach chains or slings to it
and lift it straight upward

to prevent “TMR090 Series” from
shaking. Never allow any person under “TMR090 Series”.
Use chains or slings compatible with lifting weight.
Clean the air diffusers when lifting the modules and doing
maintenance. If the sludge accumulated on the surface of air
diffusers are dried up, the rubber parts of air diffusers may get
damaged.
