instructions are written with the understanding that the individual(s) have experience in building wet wells and

DANGER!
HAZARDOUS MOVING PARTS.
To reduce risk of injury disconnect power before servicing. Never put
fingers near grinder impeller or in pump inlet when pump cord is connected or pump is operating.
In the initial installation, before sewage is admitted to basin, there is no danger on entering the basin, but after
sewage has been in the basin there is danger. Sewage water gives off methane and hydrogen sulfide gases, both of
which are highly poisonous. A breathing device may be required. Never enter basin unless cover is open and an
outside blower is used to force fresh air into the basin. Also, the worker in the basin should wear a harness with
rope to surface so that he can be pulled out in case of asphyxiation. Never work alone!
Do not exceed working load limit of lifting rope or chain. Do not use lifting rope or chain where failure could
result in loss of life.
Examine all lifting devices, rope or chain for damage before and after each lift.
Do not use any lifting devices that are not rated for and designed to lift the weights involved with these pumps.
Do not install or remove pump with person(s) in basin.
