SERIES SA-P
DESCRIPTION OF EQUIPMENT
The Series SA, and SA-P units consists of an ASME Code
stamped steel receiver (permitting operating under pressure up
to 15 psig [1.0 Bar] and equivalent temperature up to 250°F
[121°C]). Series B35 centrifugal pump(s) designed for 2 ft. (0.6M)
NPSH, corrosion inhibitor (anode), water level gauge, thermometer, pressure relief valve, thermostatic air vent trap, compound gauge, valve(s) in pump suction, and a drain (gate)
valve. Occasionally, Series SA units are fully vented; these
receivers feature ASME Code construction except the code
stamped is omitted. In addition to the above components, the
Series SA-P employs a proportioning regulator and valve (electric or pneumatic). The Series SA unit uses float switch controls.
Control panels and components supplied per specification.
When Series SA units are furnished with ASME Code stamped
receivers, relief valve and air vent trap to permit pressurization,
then the receiver inlet is directly connected to the outlet of the
steam absorption unit or other steam process equipment with-

SERIES SA
out steam traps in the return line. When used in this manner, a
separate SA unit is usually required for each independently
controlled heating unit.
It is, however, possible to use a single SA unit with multiple
heating units. Detailed information and drawings will be furnished on request.
The relief valve on the unit is set at 15 psi (1.0 Bar) and rated at
1900 pph (862 Kg/hr) steam. Any additional system protection
must be provided as required by others.
PRELIMINARY INSPECTION
Assure that there is no shipping damage.
Assure that nameplate ratings agree with job specifications and
actual conditions.
HANDLING
Use care in installing unit.
Page 3
CAUTION: UNIT LIFTING EYE
Use unit lifting eyes only to lift unit as shipped from
factory. Unit must be empty and disconnected from pipes,
anchors and other restraints. Use proper rigging pr
ocedures. Failure to follow these instructions could result in
injury or property damage.
LOCATION
Place unit for easy access to all parts. Allow adequate space
for servicing. Check ambient conditions.
NOTICE / TEMPERATURE LIMITS
Motors are designed to operate in 104°F (40°C) max. ambient.
Insulate or ventilate as required.
WARNING: EXPLOSIBLE
Do not exceed pressure rating of unit (normally 15 psi
[1.0 Bar]). Do not alter or defeat relief valve (must be 15 psi
[1.0 Bar] max.). Pipe relief valve discharge to a safe location.
Failure to follow these instructions could result in serious
injury or death.
PIPING (General)
Pipe the unit per the Elementary Piping Diagram. Locate and
support piping so as to not load the pump discharge.
RETURNS
Gravity return lines from system should be properly pitched to
drain to unit by gravity. A “Y” strainer and gate valve should be
installed in the return line.
PIPING (Relief Valve)
The discharge from the relief valve should be piped to a location for safe for potential full flow steam. There must also be
provision for drainage of the liquid discharged.
WARNING: RELIEF VALVE REQUIRED
For sale operation the system requires a relief valve
set at 15 psi (1.0 Bar) or less. The relief valve discharge must
be piped to a location where 15 psi (1.0 Bar) steam can be
safely discharged. Do not restrict, reduce or valve the relief
valve discharge line. Failure to follow these instructions
could result in serious injury or death.
WARNING: LIMITED PRESSURE RELIEF
VALVE CAPACITY
The pressure relief valve supplied on the unit may not be
sufficient to relieve rated capacity of the unit or full output of
the boiler. Relief valve supplied is rated at 1900 pph (862
Kg/hr) steam. The tank is rated to withstand 125 psi (8.5 Bar),
but the operating pressure must not exceed 15 psi (1.0 Bar).
Professional system design or evaluation, by others, must
evaluate the upstream system and provide for necessary
additional protection. Discharge thru the pressure relief
valve is a symptom of a system failure. The unit must be
valved off immediately. Failure to follow these instructions
could result in serious injury, death or extensive property
damage.
THERMOSTATIC VENT TRAP OR ATMOSPHERIC VENT
Connect piping from drain line, thermostatic vent trap, and
mechanical drain valve (if so equipped) to drain. Occasionally,
Series SA units are furnished fully vented, without thermostatic
vent trap. Oversize vent openings are then supplied; install full
size vent pipe to atmosphere.
CAUTION: NOT A CHEMICAL PUMP
Inject boiler feed compounds from chemical feed tank
into boiler feed piping – never into condensate tank. Failure
to follow these instructions could result in injury or property
damage.
FLOAT SWITCHES & MECHANICAL ALTERNATORS
Float switch and/or displacer switches, standard or proportional,
are provided to meet system r
Floats are locked in place to prevent damage during ship
equirements.
ment.
Remove shipping locks. Check factory settings. Floats and
mechanical alternators are adjustable for various levels of operation. The lead pump should start with tank 3/4 full and shut of
at 2" (51mm) or more above pump inlet. Lag pump should start
before the tank overflows. Settings should avoid “short
cycling” of the pump.
Displacer positions are adjusted by removing the contr
oller
from the top of the tank and changing cable lengths.
PROPORTIONING ELECTRIC REGULATOR
AND PROPORTIONING (SLIDE WIRE) ELECTRIC VALVE
The regulator is actuated by a float-operated mechanism. Its
function is to regulate the action of the proportioning type of
motor operated valve, so the amount of flow through the valve
is in balance with the water level change.
By accurately following the changes in the water level, the float
actuates a potentiometer slide wire located in the proportioning
regulator. Connected to a similar potentiometer in a relay and
valve operator, the regulator causes the valve to open, close, or
hold in a fixed position.
PNEUMATIC PROPORTIONING
REGULATOR AND CONTROL VALVE
The pneumatic proportional control utilizes controlled air pressure to modulate the discharge valve opening. An air pressure
switch set a 2-3 psi (0.1-0.2 Bar) starts and stops the pump(s)
while the discharge valve is essentially closed.
DISCHARGE CONNECTION – SERIES SA AND SA-P UNITS
A check valve, gate valve and square head steam plug cock
should be located close to pump in discharge line. The plug
cock(s) may be omitted on Series SA-P units equipped with
proportioning discharge valves. If discharge line is more than
100 ft. (30M) long, it should usually be one size larger than the
pump tapping. When the pump is to discharge to a vented
receiver at approximately the same elevation, the steam pressure in the receiver may be greater than the static head at the
pump discharge causing condensate and steam to be forced
through the pump. This condition can be corrected by installing
a back-pressure valve with a spring pressure approximately
equal to the maximum receiver pressure.
ELECTRICAL WIRING & CONTROLS
Connect power wiring per NEC. Recheck nameplate vs. specifications and conditions. All single phase motors have internal
thermal protection.
WARNING: HIGH VOLTAGE ELECTRICITY
Disconnect and lock out power before connecting or
servicing unit. Failure to follow these instructions could
result in serious injury or death.
f

Page 4
Three phase motors must use starters with properly sized overload relays. Overload relays furnished are designed for manual
reset.
A variety of electrical controls are available to meet system
specifications. Wiring diagrams are enclosed in electrical
panels when the panels are furnished as part of the unit.
Consult wiring diagrams for specific electrical control
information.
INSULATION
Series SA units frequently handle condensate at temperatures
up to 250°F (121°C). Insulating the receiver and return piping
will effectively conserve heat otherwise lost through radiation
and convection from the receiver shell and reduce ambient
temperatures.
PUTTING THE UNIT INTO SERVICE

WARNING: EXPLOSIBLE
Improper installation or maintenance of tubular glass
can cause immediate or delayed glass breakage resulting in
bodily injury. To avoid br
eakage observe the following Do’s
and Do Not’s and Use and Care Instructions, as well as
tubular gage manufacturer’s instructions. If a gage glass
breaks, contained substances can be released and glass
can be blown out of the unit with great force. Always wear
safety glasses when looking toward a gage or working on a
gage glass assembly. Guard against the possibility of fir
e
and explosion. Protect glass from impact, scratches, other
surface damage and sudden temperature changes. These
can weaken or stress the glass and lead to breakage.
Failure to observe the following Do’s and Do Not’s can result
in glass breakage and its explosive release of pressurized
system contents and flying glass particles.
DO NOT’S
DO NOT work on any gage until you have carefully read these
warnings & instructions.
DO NOT reuse any tubular glass, packing, or seals.
DO NOT use glass that is scratched, chipped, or otherwise
damaged. Used glasses may contain damage and are poor
safety risks.
DO NOT exceed the glass or gage manufacturer’s recommended working pressure or maximum recommended gage
glass length.
DO NOT bump, impact or scratch the glass.
DO NOT tighten gland nut and packing beyond gage manufac-
turer’s recommendations.
DO NOT operate gages unless gage valve sets are equipped
with drain vent and safety ball check.
DO NOT attempt to clean glass while the unit is in operation.
Cleaning should be done without removing the gage glass.
DO NOT attempt to inspect the glass, to adjust tie rods, pack-
ing nuts or glands, to inspect or tighten other fittings without
isolating the gage from the pressure vessel and opening the
drain vent.
DO NOT weld, impact, or sandblast in the gage glass area
without protecting the glass.
DO NOT have glass-to-metal contact.
DO NOT subject gage glass to bending or twisting stresses.
DO NOT allow the gage glass to contact the bottom of the
packing gland.
DO’s
DO inspect the gage glass daily, keep maintenance records,
and conduct routine replacements.
DO install protective guards where necessary to protect
personnel.
DO protect the outside of the gage glass from sudden temper
ature changes, such as drafts, water spray, etc.
DO remove all deposits from the seal areas, the gland nuts,
glands (where used) and use new packing before installing a
tubular gage glass.
DO examine gage glass for damage and seals for hard deposits
and tears.
DO verify that the tubular gage glass, gland, nuts, packing, etc.
are the correct size and type before installing.
DO ensure that system is protected by safety shut-off system
(e.g. safety ball check).
MAINTENANCE
Examine the gage glass regularly for any signs of clouding,
scratching, erosion, or corrosion. In new processes, the glass
should be inspected daily until the need for replacement
becomes apparent. This will help establish the routine inspection and routine replacement cycles.
CLEANING
Keep gage glass clean using non-abrasive commercial glass
cleaners. Where regular cleaners do not seem to work, use
dilute acids such as Hydrochloric (muriatic) acid. Always
observe safety rules when handling hazardous cleaning solutions. Never use wire brushes, metal scrapers, or harsh abrasives which could scratch the glass.
INSPECTION
Scratches, corrosion, chips, surface flaws, or nicks on the surface or edges weaken the gage glass. To examine for these,
shine a very bright concentrated light (“Burton Lite” or powerful flashlight) at about 45° angle. Anything which glistens and
catches the fingernail or any star-shaped or crescent-shaped
mark which glistens, is cause for replacement. Any gage glass
which appears cloudy or roughened and will not respond to
cleaning procedures, should be replaced.
STORING
Keep gage glasses in original packaging until ready to install.
HANDLING
Avoid bumping, chipping, or scratching glass. Any glass-toglass contact can cause scratches and must be avoided.
-
INSTALLATION
Always follow tubular gage manufacturer’s recommended procedures for glass replacement.
Before installing a gage glass, remove all deposits from the seal
contact surfaces of the gland nut and the gland (where used).
Check sealing surfaces for cleanliness and smoothness. Once
a gage glass has been removed from its mounting, regardless
of the reason for its removal. Discard the glass and replace with
a new piece.
Always use new packing, seals, and/or O-rings (if required)
when replacing a tubular gage glass. Used packing seals and
O-rings will not properly support the gage glass or provide the
proper pressure seal without stressing the glass.

Page 6
1. Hold fittings rigidly to prevent misalignment, which can
cause severe bending stresses in the glass, when packing
nuts are tightened.
2. Provide metal washers so nuts can be tightened without
twisting packing or tube.
3. Provide positive, but not excessive, clearance between
glass, packing nuts, and bearing washers.
4. Keep glass short enough to allow for expansion.
5. Provide positive clearance between the ends of the gage
glass and the metal fittings. Glass-to-metal contact will
keep the gage glass from expanding and cause breakage.
6. Tighten packing nuts enough to prevent leakage, but not so
much that you hinder expansion and contraction. Follow
gage manufacturer’s r
7. Generally, you can use cylindrical or conical rubber pack
ings for LOW and MEDIUM pressures. HIGHer pressures
and HIGH temperatures may require specialized packings.
In all cases you should follow the recommendations of the
gage manufacturer.
