Air Flow Adjustment - Elite 799 User Manual

INSTALLATION TIPS:
• The pump should be placed in a location which is dry and
relatively free from dust . Do not place the air pump on
carpet, as fibers might collect on the pump and clog free-
flowing air from entering pump. This will reduce the air
output and the service life of the pump.
• Air control valves with multiple outlets may also be used to
power additional apparatus in the aquarium. When using
multiple air valves, it is recommended to have one more
outlet than required by the accessories; this will be used to
bleed overproduction of air due to back pressure build up.
For more information about back pressure see (BACK
PRESSURE).
• Air Pumps can be used to operate a variety of aquarium
accessories such as air stones, corner filters, under gravel
filters, and ornaments. Follow installation instructions for
your particular aquarium accessory product.
CAUTION:
Care must be taken during installation to ensure that water
cannot siphon out of the aquarium through the air hose and
damage the air pump.
removing filter(s), air stone(s), ornament(s) or any other air-
driven aquarium accessory from the aquarium, do the
following:
1. Install a Check Valve
2. Leave the pump running while you disconnect the tubing
from the pump. Disconnect tubing and tape this end of the
tubing to the very top frame of your aquarium.
3. Filter(s), air stone(s) and other air-driven ornaments can now
be safely removed from your aquarium.

AIR FLOW ADJUSTMENT

In order to achieve correct airflow, a balance between the
valve setting and the pump output is necessary. The ideal
setting is obtained by minimum back pressure or nonrestriction
of flow of air. Never physically restrict the output of the pump.
Restriction causes damage to the diaphragm. (SEE BACK
PRESSURE). Adjust air valve output as required.
To prevent back-siphoning when
