DI water requirements
•
Verify regularly that water processing equipment
is operating correctly. The presence of chlorides in
improperly processed DI water eventually causes pitting
and failure of the heat exchanger tank and its components.
Your DRI‑STEEM warranty does not cover damage caused
by chloride corrosion.
•
DI models do not require regular cleaning, although
regular inspections are advised.
•
DI models do not require skimming or draining
and flushing to remove precipitated minerals. All
DI humidifiers should be drained at the end of a
humidification season either by manually opening
the drain valve or by programming the humidifier to
automatically drain at end‑of‑season (electric drain valve
and Vapor‑logic3 required).
Note: Although DI models do not require regular tank
cleaning, this service kit contains a new cleanout
plate gasket and nuts. If replacing the gasket, replace
the nuts also, and torque the nuts to 25 to 35 in‑lbs
(2.8 to 4.0 N‑m).
Start-up
Perform the Annual safety checks in the Inspection and
maintenance section on page 4.
If resuming operation after service, do not leave the humidifier
unattended; allow it to cycle through multiple fill cycles to
verify that all serviced parts are functioning properly. See the
humidifier's Installation, Operation, and Maintenance manual
for start‑up details.
