OVERVIEW
SAFETY PRECAUTIONS
 Ensure that the control panel is grounded to avoid
possible electrical shock or damage to equipment.
 Before servicing, turn off all power and assure power
“lockout” to avoid possible electric shock.
 Disconnect external power to the control panel before
removing or replacing fuses.

INSTALLATION
LOCATION
Select a location that provides:
• Electrical Supply
• Potable Water (Clean)
• Proximity to the Point of Use
• Easy Handling and Storage of Polymer
• Access to Unit
• Protection Against Severe Weather
UNPACKING
Examine package contents for damage. Report any to
freight forwarder. Check plastic bag(s) for contents
against individual packing list(s).
NOTE: Disregard any moisture; this unit was
wet tested.
CONNECTIONS
• Use Teflon tape on threads. Use joint compound
(pipe dope) in small amounts, if necessary.
• Do not over-tighten fittings.
• Insure that supply water pressure is less than 100
psi.
• Install water isolation valve with unions.
• Insure that neat polymer feed line has a flooded
suction.
NOTE: To enhance performance, reduce the
number of piping turns and elevation changes.
STORAGE
Store in atmosphere controlled environment. Protect
from extreme temperature (above 110°F, 52°C, below
32°F, 0°C) and wide ambient temperature fluctuations.
Protect from direct weather exposure, i.e., sun, rain,
high wind, etc.

INSTALL, OPERATE, OR SERVICE THIS
UNIT.

OPERATION
GENERAL
This PolyBlend unit will perform the following
functions: meter polymer dosage, regulate mixing
water, provide uniform dilution and activation, operate
on-line continuously, and feed solution to the point of
use.
Neat polymer from the metering pump and dilution
water controlled by the solenoid valve enter the mixing
chamber. Dilution and activation occur, yielding
prepared solution ready for use.
Neat polymer dosage rate is adjusted at pump face or at
electronic controller (REM-1E, SCR, etc.). Primary
dilution (and post dilution) water are controlled by
individual flow control valves.
START-UP
Step 1: Switch pump to external mode at pump face.
Step 2: Prime polymer pump, using priming kit
provided with unit.
Step 3: Place both power switches in Off position.
Step 4: Energize power circuit that feeds unit.
Step 5: Place main power switch in On position.
Solenoid opens. Allow mixing chamber to
fill with water by opening primary dilution
water control valve.
NOTE: Do not turn mixer motor on until
chamber is filled with water, running dry will
damage mechanical seal
Step 6: Place mixer power switch in ON position.
Mixing chamber motor starts.
Step 7: Access REM-1E controller to turn pump
On/Off for polymer output adjustment. Output
can also be adjusted at pump face by varying
the stroke length.
NOTE: For optimum pump performance, keep
stroke frequency as high as possible. This is done
by decreasing the stroke length setting. More
stroke repetition with a shorter length is better
than fewer strokes with a long stroke length. If
stroke length is too short, pump prime may be
affected.
Step 8: Adjust water flow at mixing chamber by
turning control valve. (The other control valve
should be turned for post-dilution adjustment, if
applicable.)
NOTE: Do not run polymer pump unless water
flow is established. Polymer alone can plug
discharge plumbing.
WATER PRESSURE
This unit is equipped with a differential pressure switch.
It has been factory set. See Appendix for details.
SOLUTION OUTPUT
Unit output is determined by setting pump stroke length
and stroke frequency together with setting dilution
water flow. Establish desired solution volume and
solution concentration, then proceed.
EXAMPLE: 100 GPH (380 LPH) of .5% polymer
solution desired. A 2 GPH (7.6 LPH)
diaphragm pump is used.
— Determine neat polymer requirement.
(100 GPH) x (.005) = 0.5 GPH neat polymer
(380 LPH)) x (.005) = 1.9 LPH neat polymer
— Determine pump usage.
(0.5 GPH) ÷(2 GPH) = 25% pump capacity
(1.9 LPH) ÷(7.6 LPH) = 25% pump capacity
— Set Controls
A 2 GPH (7.6 LPH) pump @ 100% stroke length and
25 strokes per minute will deliver 0.5 GPH (1.9 LPH).
However, 2 GPH (7.6 LPH) pump @ 50% stroke length
and 50 strokes per minute will also deliver 0.5 GPH
(1.9 LPH) with a more homogeneous mix.
NOTE: Do not exceed polymer concentrations of
1% in the PolyBlend.

MAINTENANCE
SHUTDOWNS
If out of service more than one week, flush mixing
chamber.
• Turn pump off.
• Place unit power switch in On position to establish
water flow for five minutes.
If out of service for more than two weeks, flush pump
and mixing chamber.
• Connect pump suction to a container of mineral oil
(not water).
• Place unit power switch in On position to establish
water flow.
• Turn pump on and run for three minutes.
• Turn pump off.
• Continue water flow for five additional minutes.
• Drain water from chamber and piping to prevent
freezing.
MAINTENANCE
1. Clean ancillary water and/or polymer strainers
weekly.
2. Flush system monthly following one-week
procedure.
3. Refer to the appendix for specific information on
drawings, part identification, and components.
SPECIAL TOOLS
No special tools needed for operation, maintenance, and
repair of components.
LUBRICATION
No lubrication is required.
PREDICTED LIFE SPAN
There is no predicted life span of wear parts as each
application and operation varies.
OPERATING PROCEDURES
For normal operation, once settings are adjusted based
on operation parameters, the system can simply be
turned ON or OFF. Special operating instructions for
Seasonal operation do not apply.
EMERGENCY OPERATING INSTRUCTIONS
Emergency operating instructions do not apply to
Siemens Water Technologies – Stranco Products
equipment. In case of an emergency, TURN OFF
POWER TO STOP RUNNING.
DISASSEMBLY, REPAIR, & REASSEMBLY
This equipment is an open-frame design. It allows for
easy removal of all components. There are no special
procedures for removal of parts. If assistance is
required, contact Siemens Water Technologies –
Stranco Products Technical Service at 800-882-6466.
