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)!
2.3.5. Instructions to Operation
Do not break or work the power cord.
Do not touch the power plug with wet hands.
Disconnect all appliances in the aquarium or pond from
the supply mains before putting your hands into the water.
Pull off the power cord by holding the power plug.
Do not wash the air pump with water.
