MAINTENANCE
Replacement Steps - Water Filters
It is recommended that the #1 sediment filter
and #2 RO filter be replaced at least once per
season or as needed.
Do not replace the #3 staging tank. At the end
of the humidification season, unscrew the #3 fil-
ter and empty any remaining water.
When installing new filters, install #2 RO filter
first, followed by the #1 sediment filter.
End-of-Season Steps
Empty the Storage Tank
1. Close the storage tank shutoff valve.
2. Disconnect the yellow tubing from the RO
system assembly. Route the disconnected
end to a drain outlet.
3. Open the storage tank shutoff valve.
4. When water stops draining from the yellow
tube, the tank is empty.
5. Close the storage tank shutoff valve.
6. Reconnect the yellow tube to the RO sys-
tem assembly.
7. When ready to humidify again, open the
storage tank shutoff valve.
Flow Control
1. Disconnect the red tube at the connector
that is in the drain line approx. 12” from RO
assembly, leaving the connector attached
to the RO system.
2. Remove and replace the cylindrical plastic
flow control that is inserted in the end of the
red tube removed from the connector. If
the plastic flow control does not appear to
be in the end of the red tubing, it may have
stayed in the connector when the tube was
removed. Remove the old flow control from
the connector before installing the new one
in the end of the tubing.
