MONTHLY MAINTENANCE (continued)
WARNING
The liquid phosphoric acid in descaling kit 104394
can be harmful if not handled properly. Follow
these basic safety rules for handling and using
acid.
Wear protective clothing when mixing or applying
chemical cleaners. Wear rubber gloves, mask and
approved cup-type goggles.
Avoid breathing fumes. If liquid comes in contact
with skin, flush immediately with large quantities of
cold water. Remove contaminated clothing.
If chemical contacts eyes, flush with cold water for
a minimum of 15 minutes. Get
immediate medical
attention.
If chemical is swallowed or ingested, follow in-
structions on the chemical container. Get
imme-
diate
medical attention.
CAUTION
Do not use powdered sulphonic acid, part number
101751. This material will damage the float as-
sembly and other SteamCraft 3.1 components.
Do not scrape heating elements with a solid tool.
If the steamer is turned OFF, energize the steamer by pressing the
POWER switch to ON. Allow time for the steam generator to Ell (3 to 4
minutes). This assures that blowdown occurs.
1. Press the POWER switch to OFF.
2. Press the TIMED/MANUAL switch to TIMED. Set TIMER to 0.
3. After completion of blowdown (3 minutes), turn off power at the main
power switch.
4. Allow time for the steam generator and compartment to cool down.
5. Remove right side access cover (
see Figure 2-16
).
6. Remove the 3 x 3 inch cover plate or the 1-inch pipe plug from the side
of the steam generator.
7. Inspect inside of the steam generator for scale. Use a flashlight and
inspection mirror. Be careful not to drop the mirror or anything else into
the steam generator.
