PRE-INSTRUCTIONS FOR THE LIQUID DESCALING OF
BOILER BASE UNITS
PART NUMBER 106174
Enclosed is our latest instructions for the newest liquid chemical descaler.
Please note: THIS CHEMICAL IS DESIGNED TO BE USED WITHOUT ANY HEAT APPLIED. This
chemical can now be used for the two and three probe boiler base units. Because
the chemical is used without heat, there are some changes in the instructions.
They are as follows:
1. The bottle of our latest liquid descaler has a flip up spout in it like
a shampoo or liquid soap bottle.
2. The design of the bottle and the fact we can not pour the liquid into
the generator through the hand hole plate means you need to build a
special tool. We recommend you use about 24 inches of 1/4" O.D.
flexible tubing attached to a funnel. Remove the needle valve in the
upper sight gauge valve and insert this tube into the generator about
2" inches. Pull the funnel and tubing out front of and above the top
of the generator. Pour the liquid into the funnel.
3. On the right side of the two probe generator is a steam trap. The
bottom connection must be removed and capped so the liquid does not
flow through it.
4. Depending on the style of drain valve and if the unit has a TDS timer,
there are different wiring procedures.
5. The lower compartment steam solenoid valve must be open during the
filling of the generator to allow any air in the top of the generator
to escape.
6. Upon completion of the descale, check the top of the generator to make
sure the chemical has cleaned it.
If there are any questions or problems concerning these procedures, please let
us know right away at 1-800-338-2204.
