2.3.4. Instructions To Piping

The pipe to discharge the air should be hard and at least have
a inner diameter of 13mm and a outer diameter of 19mm for the EL-Single.
The air piping line should be as short and straight as possible. The total
length of air piping should be not longer than 5 m approximately. Please consult
us, for special case!
Make sure that no particles and/or bends etc. are left in the piping after its
construction. Extra pressure caused by foreign substances left in the
piping will be applied on the air pump, which will result in overheat
of the air pump. It may shorten the life of diaphragms and valves.
Connect the air pump to the air piping with the accessory L-Type-hose, and
secure the connection with a hose band.
Make sure, that the max. backpressure is not more than 200mbar
(for SLL-Series) and 250mbar (EL-Series)!
