This boiler model is equipped with a manual fill funnel (4).
To fill the boiler, proceed as follows:
In order to ensure long term troublefree boiler operation,
we recommend that the water used as boiler feed water to
be tested for hardness. If the water in your area is harder
than 1grain (17mg/L), use a water softener. The main
cause for premature heating element failure in electric
steam boilers is water hardness. If severe corrosion during
inspection of the pressure vessel as indicated in chapter
3.4 of this manual becomes evident, additional tests of
your boiler feed water must be performed. A water analysis
should be performed by a qualified and recognized water
treatment company located in your area.
Recommended levels for boiler feed water:
Recommended levels for boiler water (water inside
pressure vessel when boiler is operating)
Ensure that the discharge port is pointing toward the back
of the unit away from the operator or any aisles. If it is
required that discharge piping be installed from the safety
valve, the pipe should not be smaller than the valve outlet
and should be rigidly supported so as not to place weight
on the valve itself.
Important: No valve in this line!
This boiler model is equipped with a 15Amp, 120V AC
power cord and plug. As power supply, provide a 15Amp,
120V AC wall outlet and ensure that there is no other
significant load on the same circuit as this boiler model
draws approximately 12.5Amps.
a. Close blowdown valve (3).
b. Open upper and lower
gauge glass fixture valve.
c. Turn on the power switch
(16) on the electronic
boiler control (9) to the ON
position.
d. When the water level gets
low, the unit will shut off
automatically and the "low
Water" alarm light (15) with
be lit. To refill, turn off the
power switch (16) and
allow the steam pressure
to drop to zero.
g. If the boiler controller indicates any alarms, then press
the corresponding RESET button(s).
As soon as no boiler alarms are indicated, the HEATING
light turns on and the boiler starts to build up pressure.
Observe the pressure gauge while pressure builds up, until
working pressure is reached. The working pressure should
have been factory set to your specification. However, if you
wish to change the working pressure setting, proceed as
follows.
NOTICE Do not add any chemicals to the
boiler feed water unless
specifically recommended by a
qualified and recognized water
treatment company.

Stand clear of scalding water or steam.
Disconnect the boiler from all power
supplies.
All pressure controls are factory preset and require no
adjustment. However, if a change of the operating steam
pressure is required, then proceed as follows:
• Disconnect all power supplies from the boiler.
• Close the steam outlet valve
• Remove the cover from the pressure control enclosure.
• Turn the black knob of the operating pressure switch
clockwise to increase the pressure and
counterclockwise to decrease the pressure.
• Connect power supply to the boiler, open the steam
outlet valve, and install the pressure control enclosure
cover.
h. To shut off the boiler, turn the POWER switch on the
boiler controller OFF.
All boilers must be blown off periodically to remove
minerals, scale and other foreign matter, which accumulate
inside the pressure vessel. The concentration of this
deposit depends in part upon the condition of the water in
the area. When water is naturally soft, or has been
softened chemically, boiler blowoffs are required less often
than in areas where hard water is found. Water softeners
are suggested in hard water areas to minimize the
formation of hard scale on heating elements. Another factor
affecting water condition is the amount of condensate, if
any, that is being returned to the boiler. Since condensate
is essentially clean distilled water, it contains very few
impurities. If a large part of the condensate is being
returned and little makeup water is used, the boiler need
not be blown down as often as when little or no condensate
is returned to the boiler. We recommend blowoff of newly
installed steam boilers once per day until the first heating
element and pressure vessel inspection is performed (refer
to chapter 3.4). If no significant amount of sediment is
found on the bottom of the pressure vessel and on the
heating element sheaths, then the boiler blowoff frequency
can be reduced accordingly.
Stand clear of safety valve and scalding
steam.
This test should be performed once per month. Proceed as
follows:
• Increase the steam
pressure as shown in
chapter 2.1. to maximum
operating pressure.
• Keep the steam outlet
valve closed
• Pull the trip lever and hold
open for five (5) seconds in
order to flush off the valve
seat.
• Permit the valve to “slap”
shut. If a leak occurs,
repeat this test and if
necessary, replace the valve.
Ensure that the boiler is cold, drained
and all power supplies are
disconnected.
Clean the element rods every six (6) months. To clean the
rods, or if an element must be replaced, proceed as
follows:
• Remove the element terminal cover from the front of the
boiler.
• Disconnect and label the terminal wires
• Remove all four (4) nuts from the element flange and
pull out the heating element.
• Use a stiff wire brush to remove all scale and foreign
matter from the element rods.
• Clean the element flange surfaces before installing new
element and gasket.
Frequency: Minimum once per year.
WARNING Boiler repairs must be
performed by experienced personnel
only. Ensure boiler water is cold and drained and that
there is no pressure and all electricity to the boiler is
shutoff.
