2.5.2 Pellet Feeder Best Practices
•
The pellet feeder hopper must be maintained with
an adequate supply of pellets at all times.
•
Insert the pellet desiccant into the holder
mounted inside the hopper cover.
•
Replacement desiccants are included in each
new bottle of pellets and should replace old
desiccants whenever the hopper is refilled.
•
The hopper lid must remain tightly closed except
when refilling.
•
It is recommended that the feeder be installed in
a sheltered area to minimize the chance of water
or debris entering the hopper when the cover is
opened for refilling and maintenance.
•
When the Pellet Feeder is not in use (especially
when temperatures are near freezing), it is
strongly recommended to drain the plumbing manifold. Simply close off the inlet and
outlet ball valves and open the strainer.
2.5.3 Liquid Bio-reporter Plumbing
Bio-reporter liquid is fed via a small diaphragm pump. Plumb the discharge of the bio-reporter
pump to a point of good circulation (mixing) sufficiently away from any biocide feed points.
Connect discharge back to recirculating
system downstream from supply in basin
where possible.
Pellet Feeder requires 4 to 5 gpm flow
