♦
Turn off the power or unplug the system.
♦ Close some of the valves, allowing the airflow to be directed to a couple of airstations at a time.
♦
Close the lid and turn on the system for two minutes.
♦ Turn off the power and unplug the cabinet and close the valves that were just flexed.
♦ Close different valves and proceed in the same manner until all of the airstations have been flexed.
♦
If you have not yet balanced the AirStations, or cannot read your indicator marks, see the “AirStation™
Balancing” section. The Disk Flex Cleaning procedure is now complete.
OPERATING THE SYSTEM IN THE WINTER
Vertex Aeration Systems are designed to operate year-round in cold climates with these important precautions. If
you choose to run the aeration through the winter:
WARNING/ATTENTION
Drowning warning:
Operating in freezing conditions on an ice-covered lake will cause large open
water areas to remain at the boil sites. The ice thickness around these open areas will be much
thinner than the ice over the rest of the lake. Injury or fatality may result from falling through the ice.
Vertex strongly recommends that this danger of thin ice around the boil area be clearly posted at
frequent intervals. Owner assumes all responsibility for operating Vertex aeration systems during winter months.
Noyade attention:
exploitation dans des conditions de congélation sur un couvert de glace du lac causera de
grandes zones d'eau libre de rester sur les sites ébullition. L'épaisseur de la glace autour de ces zones ouvertes
seront beaucoup plus mince que la glace sur le reste du lac. Blessure ou décès peuvent résulter de la chute à
travers la glace. Vertex recommande fortement que ce danger de glace mince autour de la zone ébullition être
clairement affichés à intervalles fréquents. Propriétaire assume toute la responsabilité pour le fonctionnement des
systèmes d'aération Vertex pendant les mois d'hiver.
To prevent risk of freezing the entire water column, AirStations™ should be moved to a shallower portion of the
waterway (typically one-half the depth of original placement) and operated there until warmer temperatures return,
this will allow warmer water to remain in the lower regions of the waterway and prevent water column freezing.
The airline tubing on shore and the compressor hose must be insulated between the cabinet and the ground. Also,
the tubing must enter the water below the winter ice depth.
If you choose to turn off the system for the winter:
♦
Unplug the system; no other preparation is required.
*
♦
In the spring, when the system is restarted, air lines may still contain ice inside the line.
♦
One cup of
denatured alcohol
added to each frozen line will melt the ice enough to allow the compressor to
push air through the line until heat generated by the compressor melts the remaining ice.
♦ Follow the first time and spring start-up procedures.
*It is recommended that all maintenence be done prior to restarting in the spring
