CLEVELAND RANGE DESCALING KIT
INSTRUCTIONS FOR CHEMICALLY DESCALING A
STEAMCRAFT II EQUIPPED WITH A DUAL PROBE
For a thorough understanding of proper procedures and precautions, read these instructions completely before proceeding.
IMPORTANT
Before using this acid descaling product, read the safety precautions and first aid' instructions found
on the container label.
Steamcraft IIIsteamers produced after August 1, 1982 are equipped with removable side panels on the outside wall of the
steam generator for ease of cleaning in addition to chemically descaling. Peel off the tape securing the generator side wall
insulation, then swing the insulation upward to access the generator removable side panel. Remove the lockwashers and nuts
securing the removable panel, then remove the panel and gasket. Using a scoop, or a tablespoon, or by hand, remove scale
build-up from the generator. Install a new gasket, then replace the side panel, securing it with the lockwashers and nuts to 30
inch-pounds torque.
DO HOT OVER-TORQUE TEE NUTS
, as the studs will break off. There is never any pressure in the
generator, and therefore, the nuts do not require heavy torquing to create a water-tight seal.
PREPARATION:
The plastic jar of descaling compound contains 10 pounds of sulfamic acid as a base chemical, plus a specially formulated
blend of a corrosion inhibitor, wetting agent, and color-change pH indicator to improve cleaning effectiveness in removing
hard water scales and other deposits. This product is water soluble and its solution performs most efficiently when maintained
at temperatures of 150 - 160°F (65 - 71°C). Also included is an 8 ounce poly-bag of soda ash (sodium carbonate) neutralizer.
Effective descaling and neutralizing of the Steamcraft II steam generator is generally accomplished by using 1 pound of
descaling powder (1/10 of the plastic Jar's contents) and 1 ounce of neutralizer (1/8 of the poly-bag's contents).
WARNING
: Steam and hot water may cause serious
injury and bodily harm when it is accidentally or carelessly
released. Improper handling of acid could cause serious,
permanent injury. Therefore, service of the steam
generator should only be performed by 'trained and ex-
perienced personnel, thoroughly fami
liar with servicing generators.
Mix approximately 1 ounce (1/8 of the poly-bag's contents)
of soda ash neutralizer in 1 cup of water. Bicarbonate of
Soda or baking soda are suitable alternative neutralizers.
Keep this solution nearby to be used to neutralize acid that
may be accidentally spilled.
Turn
off electrical power to the steamer at the main fused disconnect power switch. Remove the six
screws (3 left & 3 right)
along the lower left and right edges of the once piece outer sheeting. Lift the outer sheeting straight up and off the steamer.
