ADDING WATER
It may be necessary to replenish water in the jacket when the low water indicator comes on. Do
so as follows:
• Unit should be completely cold and off.
• For reference, the total amount of distilled water contained in each unit, and amount to be
added in a low water condition is listed below:
Model Total Amount of
Distilled Water Amount of Water to be Added
in a Low Water Condition
KLS-20G 6 Gallons 135 fl. oz. (4 L)
KLS-40G 9 Gallons 236 fl. oz. (7 L)
KLS-60G 12 Gallons 338 fl. oz. (10 L)
RE-ESTABLISHING VACUUM:
With the kettle completely cold a vacuum of 25 to 30 inches mercury column (M.C.) should be
maintained as indicated in the green zone on the pressure gauge on the front control panel. If
at any time the vacuum is not in the green zone, vacuum should be re-established.
With the kettle empty, turn the thermostat knob to the highest temperature. When the pressure
gauge reaches 20 psi, turn thermostat off, open the pressure relief valve until pressure gauge
reads 1 psi, then sharply release it. This should remove the air and any loss in performance
should return.
Should the kettle fail to maintain a vacuum after repeated attempts to establish it, further checks
should be made to see if the pressure relief valve is leaking or if there are any leaks in the
pressure relief valve piping, copper lines going to the pressure switch, pressure gauge or
thermostat fitting.
CONTROL CIRCUIT FUSES
The control circuit is protected by a 3 amp. fuse which is located inside control panel, top right
side above transformer.
Should the unit fail to turn on, check this fuse by removing it and either replacing it or testing it
with a continuity tester. If the fuse is good, check the main power circuit breaker, which should
be external to the kettle.
