Usage instructions
The following are instructions for using DRI-STEEM Humidifier
De-scaling Solution and DRI-STEEM Humidifier De-scaling
Neutralizer to remove scale and other related deposits in industrial and
commercial humidifiers.
IMPORTANT!
Safety gear
Inspect humidifier tanks regularly and perform
humidifier de-scaling maintenance as needed to
keep humidifiers operating at peak efficiency.
Use proper safety gear including the following:
• Rubber or neoprene gloves
• Anti-splash goggles
• Rubber apron and/or boots
• Dust mask when using Humidifier De-scaling Neutralizer
Scale buildup on humidifier heaters and heat
exchangers acts as an insulator, reducing
humidifier performance while increasing energy
costs.
Supplies required
• Humidifier De-scaling Solution
• Humidifier De-scaler Neutralizer, if required by federal, state or local
codes
• pH meter or indicator strips (pH test strips are included with the
De-scaling Solution)
• Portable mixer (optional) (e.g., cordless drill with mixer attachment
or stir stick)
• Humidifier Installation, Operation, and Maintenance manuals
(IOMs) for reference
• Tools for servicing
• Additional water source (e.g., plastic bucket and hose)
IMPORTANT: These products are not to be used for cleaning
DRI-STEEM XT humidifiers. XT humidifiers have disposable
evaporating chambers that do not require cleaning.
De-scaling process for GTS, STS, LTS, Vaporstream humidifiers
IMPORTANT: See the section titled “De-scaling process for
Vapormist, CRUV, Humidi-tech, and VT humidifiers” for instructions
regarding these humidifiers.
1. Review MSDS sheet for safe handling and proper use of
Humidifier De-scaling Solution and Humidifier De‑scaling
Neutralizer, in addition to instructions provided in this document.
2. Remove the humidifier from service before beginning to clean the
humidifier. This can be accomplished by turning off power to the
humidifier.
IMPORTANT: If the humidifier has a normally open drain valve
(typical on units installed in outdoor enclosures), the humidifier
must remain powered to keep the drain valve closed. To remove
from service a humidifier with a normally open drain valve, use
the Vapor-logic keypad/display to change the control mode from
Auto to Standby.
3. Refer to your humidifier IOMs for specific information regarding
how to prepare the humidifier for service.
DRI-STEEM Humidifier De-scaling Solution and Neutralizer Usage Instructions • Page Usage instructions
4. Remove the humidifier tank cover. If you have a GTS04
humidifier, access the tank through the probe plate.
5. Drain the humidifier to remove loose deposits and test for any
draining issues prior to adding Humidifier De-scaling Solution.
Use the manual override or ball valve for draining
IMPORTANT: If the humidifier has a normally open drain valve,
change the control mode using the Vapor-logic keypad/display
from Standby to Manual Drain.
6. When draining is complete, close drain valve.
IMPORTANT: If the humidifier has a normally open drain valve,
change the control mode using the Vapor-logic keypad/display
from Manual Drain to Standby.
7. If the humidifier is in an air handler, shut down air handler prior
to cleaning.
CAUTION! Using the Humidifier De-scaling Solution can result
in off-gassing of carbon dioxide and/or non-hazardous fumes.
8. See the table on the last page of this document for recommended
amount of Humidifier De-scaling Solution.
9. Fill the humidifier with cold water halfway to the overflow port.
10. Turn power off to the humidifier if not already done, or place in
Standby Mode for humidifiers with a normally-open drain valve.
11. CAUTION! Remove probe assembly from humidifier before
adding Humidifier De‑scaling Solution to prevent damaging
probe.
12. Add the amount of Humidifier De-scaling Solution to the half-full
tank per the table on the back cover of this document.
13. After the Humidifier De-scaling Solution is added, finish filling
the humidifier with water manually (e.g., using a bucket) to 1"
(25 mm) below the overflow port.
CAUTION! Be careful to avoid splashing solution on skin or in
eyes while adding the remaining water. Use proper safety gear.
14. Use a portable mixer or similar device to agitate and mix the
solution.
15. Place the cover on the humidifier slightly ajar to allow the solution
to be vented.
16. Maintain a solution pH between 2 and 4 by adding additional
De-Scaling Solution as needed. Use proper safety gear.
17. De-scaling duration depends on several factors including: quantity
of scale, type of scale, and the pH of the solution. The de-scaling
process can last up to 8 hours.
Page • DRI-STEEM Humidifier De-scaling Solution and Neutralizer Usage Instructions
Usage instructions
18. Allow the solution to dissolve scale while checking on the progress
every 2 hours up to a maximum of 8 hours. For increased
performance, continue agitation throughout the de-scaling process
and maintain a pH close to 2.
Measuring pH
19. De-scaling is complete when the majority of scale has been
dissolved or after 8 hours has passed.
If using a pH meter and probe, follow the
instructions that came with your pH meter and
probe.
20. After de-scaling is complete, dilute the solution to a pH between
5 and 9. This can be accomplished by either manually filling the
humidifier while allowing diluted solution through the overflow
port, or by adding Humidifier De‑scaling Neutralizer (see
instructions below).
If using pH paper strips, insert a strip into the
tank water and remove. Compare the color of the
strip to the color key to determine pH.
CAUTION! Do not leave humidifier unattended while diluting or
neutralizing to avoid spills or overflowing.
21. For neutralization use the following steps:
a. Measure the pH of the solution in the humidifier tank.
b. Measure out 1 lb of Humidifier De-scaling Neutralizer per
1 gallon of Humidifier De-scaling Solution used (see the table
on the last page of this document for reference).
c. SLOWLY, add the Humidifier De-scaling Neutralizer to
the humidifier while monitoring the level of solution in the
humidifier.
Figure -1:
Typical overflow port, drain locations
STS humidifier
CAUTION! The combination of the two chemicals will cause
bubbling and release of carbon dioxide. If the neutralizer is
added too quickly, the humidifier can overflow.
d. Alternately, agitate the solution to ensure proper mixing.
e. Once the neutralizer has been added and bubbling has stopped,
measure the pH. Neutralized pH should be between 6 and 8.
f. If pH is not between 6 and 8, add acid (De-Scaling Solution)
to lower pH, or add base (De-Scaling Neutralizer) to raise pH
until pH is in the range of 6 to 8.
Measure pH by using a pH meter and probe,
or by using pH paper strips with a color key
(provided with De-scaling Solution).
22. After dilution has been completed, drain the humidifier while
abiding by federal, state, and local codes.

23. Rinse the humidifier thoroughly by refilling and draining until
humidifier water pH matches pH of incoming water (typically
pH 6-8).
24. If significant scale remains, remove manually or repeat the
cleaning process. Note that some residual scale may remain.
25. After cleaning is complete and humidifier properly rinsed,
re-install probe assembly and return humidifier to service.
