INSTALLATION
7.
When sufficient water has been added, remove elbow and replace pressure relief valve. Be sure to seal
threads with a pipe joint compound suitable for steam at 50 psi.
8.
The vacuum must now be re-established. See following section.
For reference, the total amount of distilled water contained in each unit is listed below:
KTLE-20 1.5 gals. U.S.
KSLE-20 7.2 gals. U.S.
KTLE-40 2.5 gals. U.S.
KSLE-40 15.6 gals. U.S.
KTLE-60 3.0 gals. U.S.
KSLE-60 22.8 gals. U.S.
RE-ESTABLISHING VACUUM:
With the kettle completely cold a vacuum of 25 to 30 inches mercury column (M.C.) should be maintained as
indicated by the pressure gauge on the front control panel. If at any time the vacuum is less than 25 inches M.C. the
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 manometer 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.
ELECTRICAL CONNECTIONS:
208/240 Single and Three Phase:
I.
To connect to supply wires, route supply wire through hole in bottom of control compartment and connect to
contactor. Be sure to refer to wiring diagram and rating plate on each unit for proper connection, voltage and
amperage.
480 Three Phase:
II.
Units with this electrical rating are factory equipped with a transformer to control voltage to control circuit. Refer
to wiring diagram and rating plate on each unit for proper connection, voltage and amperage.
WATER CONNECTION:
On units equipped with an optional water fill valve connect a water line (minimum 1/4 ") to the valve with a 1/4" NPT
female fitting. Units with dual (hot & cold) valves must have the hot water line connected to the side with the hot water
valve
(Red)
and cold water valve (Blue). Plastic or rubber hose is not recommended, as it may melt against the hot
kettle side.
UNITS WITH CASTERS:
For a unit equipped with casters, the installation shall be made with a gas connector that complies with the standard
for connectors for movable gas appliances, ANSI Z 21.69-1979. Adequate means must be provided to limit the
movement of the unit, without depending on the connector and any quick disconnect device or its associated piping to
limit the unit's movement. If disconnection of this restraint is necessary to move the appliance for cleaning, etc.,
reconnect it when the appliance is moved to its originally installed position. A flexible conduit and adequate strain
relief must also be provided for the power supply connection.
If the unit is also equipped with an optional water fill valve, it too must be installed with a flexible water supply tube, a
quick disconnect, and strain relief.
WARNING:
DO NOT ALLOW ANY TAMPERING OR ADJUSTMENT OF ANY CONTROL OR WIRING. THE
UNIT IS FACTORY SET. ADJUSTMENT OF ANY INTERNAL COMPONENT, OTHER THAN THE
FIELD TERMINAL BLOCK, CAN VOID THE WARRANTY.
