MODEL 22CET3.1 and 22CET6.1, BOILERLESS STEAMER DESCALING PROCEDURE (For
DISSOLVE
®
Descaler Solution Part No. 106174)
•
The entire procedure must be read and fully understood before beginning descaling.
•
This procedure takes about 1 hour 30 minutes to complete.
•
Repeat this procedure as needed for heavy scale buildup.
•
Regular cleaning of the steamer with vinegar per the instructions found in the Shutdown and
Cleaning Instructions may help reduce need for descaling. See Chapter 6.
•
Sides, back, and top of steam compartments may be descaled with a vinegar solution and a soft
brush. See Chapter 6.
1) Open the door to the cooking compartment.
2) Set the TIMED/MANUAL switch to TIMED
OR
the ON/OFF switch to OFF.
3) Set the ON/OFF lever to the OFF position.
•
The 3 minute drain cycle starts.
4) Remove the Pan Racks and KleanShield
from inside the steamer.
•
Heavily scaled pan racks and KleenShield™ may be descaled by soaking them in a solution
of 1 part Dissolve® and 4 parts water, rinsing thoroughly with cold water, and washing them in
a dishwasher.
5) Remove any loose scale from the bottom of the steamer.
6) When the drain cycle is done
,
turn the ON/OFF lever to ON to refill the unit.
7) Do not start the timer.
8) Leave the door open.
NOTE: DO NOT HEAT THE STEAMER DURING DESCALING.
9) While the reservoir is filling with water, pour 1 to 1 ½ quarts (about a third of a 1-gallon bottle) of
DISSOLVE
®
descaler solution into the water reservoir.
•
While adding
DISSOLVE
®
descaler to the reservoir, pour it in slowly to avoid splashing the
liquid or overflowing the reservoir.
10) After automatic fill ends, turn OFF the Main External Power Switch. See Figure 3-1.
11) Leave the door open and let the
DISSOLVE
® work for 1 hour.
12) At the end of 1 hour, set the ON/OFF lever to the OFF position.
13) Turn the power ON at the Main External Power Switch.
14) After the 3-minute drain cycle completes, turn the ON/OFF lever back ON. (NOTE: If the reservoir
does not fill, dry off the water probe assembly).
15) After filling stops, add 1/2 gallon of water to the reservoir. Do not overflow the reservoir.
16) Turn the ON/OFF lever OFF to start the drain cycle.
17) After the reservoir drains, set the ON/OFF lever to the ON position to refill the reservoir.
18) Close the cooking compartment door and set the timer for 20 minutes (ON/OFF Control Models:
set the control to ON.). The steamer heats to normal operating temperature.
19) After 20 minutes turn OFF ON/OFF controls and turn the ON/OFF lever to OFF.
20) The 3-minute drain cycle starts.
•
This is the final rinse of the reservoir.
21) If the reservoir drains slowly even after being descaled, turn OFF the steamer and clean the
drains with a NSF approved drain cleaner.
22) Once the scale is removed and the drain flows freely, the steamer is ready for normal operation.
