Installation and operation
Installation:
The pump must always be installed above the water level. If the pump is set below the back
flowing of the water may cause an electrical short circuit, leading to leakage and premature
pump failure.
The pump must be located on a level platform to prevent biased strain on the diaphragms that
could lead to reduced component life of the blower.
Environment:
Ensure that the unit has good ventilation, especially when subjected to severe operating
conditions. If installed in a cabinet, sufficient ventilation (louvered vents) is essential to
prevent overheating. A cool ambience will ensure longer diaphragm and valve life.
The pump should not be operated in a dusty environment. Overheating due to blocked filter
elements may shorten the life of the diaphragms and valves. Where the air is dirty,
corresponding filters should be provided.
Medium Quality:
The pumps were specially developed for transporting air. The atmosphere humidity should
not be higher than 90%. Inflammable or aggressive gases and vapours should not enter the
pump as the flow path leads to current carrying parts. A requirement for transporting gases or
vapours is that the medium has been previously tested to their resistance and operating
safety. This test must take place on the initiative of the user.
Piping:
Select tube size, lengths and accessories to keep the pressure loss as small as possible, in
particular:
…
Make the piping as short and straight as possible
…
Do not use tubing of smaller diameter than the port of the unit, inside ÿ min. 19 mm
for SLL units
…
Utilize large valves of smaller diameter than the blower's connector port. Use check
valves that provide the lowest pressure drop rather than spring loaded valves.
…
Select low air loss diffusers for aeration.
Maintenance:
Apart from occasional filter cleaning and the simple replacement of some components, such
as broken diaphragms, long term maintenance free operation is ensured. Complete service
kits are available.
Storage:
The pumps may not be stored at less than -10ƒC. The permanent magnet would be
weakened in such a case, and the performance may be affected.
The pump may not be stored in direct sunlight or at high temperatures as the rubber parts
may age prematurely.
Guarantee:
12 months works guarantee
