AUXILIARY LOW WATER CUT OFF
• For model SSB boilers SSB81017MR
(with manual reset).
Senses water level electronically using a resistance
probe. When a low water condition is detected,
the contactor control voltage circuit is interrupt-
ed and the heating elements are de-energized.
When water level returns to proper levels voltage
is restored to the contactor coils and the ele-
ments are re-energized. For controls with a man-
ual reset button voltage to the contactor coils is
not restored until the water level has returned to
proper operating levels and the reset button is
pushed. Do not depress the reset button before
the correct water level is achieved.
LINE PRESSURE WATER FEED SYSTEM
• For model SSB boilers
PN
PN SSB99117
Water feed system used to supply makeup water
to the boiler when incoming water line pressure
is 10 psig greater than the operating pressure of
the boiler. Completely factory plumbed and
wired; 0-100psig range; 1/2” NPT size. Consists of
strainer, solenoid valve (120/1/50-60Hz), and check
valve for automatic feed. For SSB boilers PN
SSB99117 components are of stainless steel con-
struction.
HIGH PRESSURE WATER FEED SYSTEM
• For model SSB12-72 PN SSB38002
• For model SSB100-180 PN SSB38020
Used to supply makeup water and to maintain con-
stant water level when the boiler operating pressure
is equal to or greater than incoming water line pres-
sure and condensate is not returned to the boiler.
• SSB38002A – Range is 0 – 100 psig, 1/2” NPT size con-
sisting of strainer, solenoid valve and 1/3 HP 120/1/60
motor and pump.
• SSB38020A – Range is 0 – 125 psig, 3/4” NPT size con-
sisting of strainer solenoid valve and 1/2 HP 120/1/60
motor and pump.
These assemblies are mounted on rubber shocks and
secured to a steel base mounting plate. These units
require field plumbing and wiring to the boiler.
SSB38002 and SSB38020 pump components are of
stainless steel construction.
AUTOMATIC BLOWDOWN SYSTEM
• Extends life of boiler
• Saves labor costs
• Starts the boiler automatically every day
• Shuts down the boiler every day
• Automatically blows down the boiler every day
• Completely programmable, can skip days, different
start and shutdown times, different operational dura-
tions.
• SSB81600 for all model boilers.
A stainless steel, motor driven straight-through, self-
cleaning ball valve with Teflon seats handles particles
and dirty fluid without the use of an up-stream strain-
er or other cleaning device. A timer (Standard analog
time clock is set for two hour time intervals, optional
digital time clock can be programmed to one minute
intervals.) and electronic time delay relay control the
boiler and the blowdown valve. A pilot light indicates
when the blowdown valve is open. The valve shall be
plumbed to a proper drain or receptacle. An automatic
blowdown system can be installed on any boiler,
regardless of size operating pressure or operating duty
cycle.
