Cleaning
9. If there is difficulty removing mineral deposits or a film left by hard water or food
residues, use a de-liming agent such as LoLo De-limer De-Scaler (Part Number
156707), Lime- Away from ECOLAB or an equivalent, following manufacturer
directions. Rinse and drain the unit thoroughly before use.
10. If cleaning problems persist, contact your cleaning product supplier for assistance.
The supplier has a trained technical staff with laboratory facilities to serve you.
CAUTION
Maintenance
NOTE:
Contact a LoLo Authorized Service Representative when repairs are required.
Periodic inspection and regular maintenance will minimize equipment down time and
increase the efficiency of operation. The following should be checked:
1. general maintenance
a. Keep the primary burner gas jet air inlets free of dust and lint.
b.
The pilot flame should be blue. It should envelop about 1/2 inch (12 mm) of
the flame sensor tip.
c.
Keep electrical wiring and connections in good condition.
2. jacket vacuum - Removing Air From jacket (by Operator)
Every day, while the kettle is cold, check the pressure/vacuum gauge. A
positive reading or a negative reading between zero and 20” of vacuum on the
pressure/vacuum gauge indicates excess air in the jacket. Air in the jacket
slows kettle heating and can prevent the kettle from reaching operating
temperature. To remove air:
a. Start the kettle. (See the Operation section).
b.
ImPORTANT
: Make sure the elbow on the outlet of the pressure relief valve is
turned so that escaping steam is directed down toward the floor. Be sure and
follow the instructions on the attached pressure relief valve tag.
c. When the pressure/vacuum gauge reaches a positive (above zero) pressure
reading of 5 PSI, release trapped air by lifting the pressure relief valve ring for
about one second. Repeat this step, then let the valve ring snap closed, so
the valve will seat properly and not leak.
3. Test Pressure Relief valve (by Operator)
At least twice a month, test the pressure relief valve. Test the valve with the
kettle operating at 5 PSI (.35 bar), by pulling the test ring for at least five
seconds. Then release the ring and permit the valve to snap shut. If the ring
does not activate, if there is no discharge or if the valve leaks, stop using the
kettle immediately and contact an Authorized Service Representative.

the kettle is cold.
