d. Check water level in the jacket to ensure that it
is between minimum and maximum marks on
glass.
e. Close the valve and reinstall the square-head
pipe plug.
f. Reestablish the jacket vacuum as described in
Paragraph 2, above, if the pressure gauge
does not show a negative reading of 20 to 30
inches mercury (Hg).
4. Water Treatment Procedure
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS STATED ON THE LABEL OF THE
WATER TREATMENT COMPOUND.
a. Obtain water treatment compound and a pH
test kit from your Groen Service Agent.
b. Fill a mixing container with the measured amount
of water required. (See table) Distilled water is
recommended.
c. Hang a strip of pH test paper on the rim of the
the container, with about 1 inch of the strip below
the surface of the water.
Troubleshooting
Your Groen kettle is designed to operate smoothly and efficiently if properly maintained. However, the following is a list of
checks to make in the event of a problem. Wiring diagrams are furnished inside the service panel and in this manual.
If an
item on the list is followed by
, the work should be done by a qualified service representative.
WARNING
BEFORE REPLACING ANY PARTS, DISCONNECT THE UNIT FROM THE ELECTRIC POWER SUPPLY
AND CLOSE THE MAIN GAS VALVE. ALLOW FIVE MINUTES FOR UNBURNED GAS TO VENT.
CAUTION
USING REPLACEMENT PARTS OTHER THAN THOSE SUPPLIED BY GROEN OR THEIR AUTHORIZED
DISTRIBUTOR CAN CAUSE OPERATOR INJURY AND EQUIPMENT DAMAGE AND WILL VOID ALL WARRANTIES.

c. Thermostat operation. The thermostat should click when the dial is

e. 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 frequently
comparing the test strip color with the color chart
provided in the test kit. Caution: Do not add
excess amount of treatment compound. Excess
amount could cause extensive corrosion.
d. Measure the water treatment compound. One
way to do this is to add the compound from a
measuring cup.
f. As you add water to the jacket, check water level to
ensure that it is in the middle of the sight glass.
g. Record the exact amounts of water and treatment
compound needed. These amounts may be used again,
if the same water sources and compound are used.
However, it is best to check the pH each time treated
water is prepared.
5. Component Replacement
WARNING
BEFORE REPLACING ANY PARTS,
DISCONNECT THE UNIT FROM THE ELECTRIC
POWER SUPPLY AND CLOSE THE MAIN GAS
VALVE. ALLOW FIVE MINUTES FOR UNBURNED
GAS TO VENT.
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 cmponents are wired
in the same manner as old components. An examination
of the the circuit schematic shows that the safety
componenets 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 a certified Groen Service Agency for
assistance.
