Maintenance
D. Water Treatment Procedure
A Maintenance & Service Log is provided at the back of this manual with the
warranty information. Each time maintenance is performed on your kettle, enter
the date on which the work was done, what was done, and who did it. Keep this
manual on file and available for operators to use.
Periodic inspection will minimize equipment down time and increase the ef-
ficiency of operation. The following points should be checked:
1. Obtain water treatment compound and a pH test kit from your Service
Agent.
2. Fill a mixing container with the measured amount of water required. (See
table). Distilled water is recommended.
3. Hang a strip of pH test paper on the rim of the container, with about 1
inch of the strip below the surface of the water.
4. Measure the water treatment compound. One way to do this is to add the
compound from a measuring cup.
5. Stir the water continuously, while you slowly add treatment compound,
until the water has a pH between 10.5 and 11.5. Judge the pH by fre-
quently comparing the test strip color with the color chart provided in the
test kit.
6. As you add water to the jacket, check water level to ensure that it is be-
tween minimum and maximum marks on glass or at the top of the sight
glass port (see photo on page 15). Stop adding water when it reaches the
maximum marker on the gauge.
7. Record the exact amounts of water and treatment compound needed.
These amounts may be used again, if the same water sources and com-
pound are used. However, it is best to check the pH each time treated
water is prepared.
E. Component Replacement
When component replacement involves breaking a gas pipe connection, check
the new connection with soap solution or an appropriate leak detector. DO NOT
USE A FLAME TO TEST FOR LEAKS.
Internal wiring is marked as shown on the circuit schematic drawings (inside
control housing and in this manual). Be sure that new components are wired in
the same manner as old components. An examination of the circuit schematic
shows that the safety components are wired in series. In most cases, a faulty
component may be isolated with a jumper wire to verify that the component is
faulty. If this determination is made, contact an Authorized Service Agency for
assistance.
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS ON THE LABEL OF THE
WATER TREATMENT COMPOUND.
WARNING
BEFORE REPLACING ANY PARTS,
DISCONNECT THE UNIT FROM THE ELECTRIC
POWER SUPPLY AND CLOSE THE MAIN GAS
VALVE. ALLOW FIVE MINUTES FOR
