Determining Output for Dual Head Dual
Control Models
• The dial ring for adjustable pumps is marked
L-10; L=5%, 1-10 indicates 10% increments of
maximum output.
• The turndown ratio is 20:1.
• On the MDC models, the outer pump head
operates on a percentage of the inner head
(closest to the motor).
• Setting #10 on both pump heads will deliver the
pump’s maximum output and is the only time each
pump head will output the same amount.
Example Using 100MDC5
• Decide on the desired output for the inner head.
• Note the setting on the dial ring that represents the
desired output.
For example setting #4 = 40% of max output
In the 100MDC5 model, setting #4 = 20 GPD
• Repeat the above steps to calculate the output of the
outer head.
Using setting #3 in this example,
#3 = 30% of the inside head output
20 GPD x 30% = 6 GPD
In this example using pump model 100MDC5,
the output for the inside head would be 20 GPD
and 6 GPD for the outside head.

Installation – additional safety instructions
NOTICE: Indicates special instructions or general mandatory action.
Read all safety hazards before installing or
servicing the pump. The pump is designed
for installation and service by properly
trained personnel.
Use all required personal protective
equipment when working on or near
a chemical metering pump.
Install the pump so that it is in compliance
with all national and local plumbing and
electrical codes.
www.stenner.com18
Use the proper product to treat
potable water systems, use only
chemicals listed or approved for use.
Install the pump to work in
conjunction with pool, spa,
well pump, or system controls.
Installation continued – mount pump
MOUNT PUMP
Select a dry location (to avoid water
intrusion and pump damage) above the
solution tank. Best recommended location
is above the solution tank in a vertical
position with the pump head pointed
downward and the spill recovery (see
next page) in place to reduce the risk and
severity of damage.
To prevent pump damage in the event of
a pump tube leak, never mount the pump
vertically with the pump head up.
To avoid chemical damage from fumes,
do not mount pump directly over an open
solution tank. Keep tank covered.
Avoid flooded suction or pump mounted
lower than the solution container.
Draw solution from the top of the tank.
If pump is installed with a flooded
suction, a shut-off valve or other device
must be provided to stop flow to pump
during service.
US and Canada call 1.800.683.2378, other countries call 1.904.641.166619
1. Use the mounting bracket as a template
to drill pilot holes in mounting location.
2. Secure bracket with fasteners or wall
anchors. Slide pump into bracket.
Provide 8" clearance to allow pump
orientation to be reversed during tube
replacement. Do not allow water intrusion
into the motor or corrosion and damage
will occur.
To prevent motor damage, verify with a
volt meter that the receptacle voltage
corresponds with the pump voltage.
3. Plug cord into receptacle and turn the
motor power switch on. If the pump is
adjustable, turn the dial ring to 10.
4. Activate the pump by the pump control
(flow switch, pressure switch, etc.) and
verify rotation of the roller assembly
within the clear pump head. Turn pump
switch off.

Installation continued – spill recovery
SPILL RECOVERY
In case of tube rupture, chemical
drains back into solution tank,
preventing spillage onto
ground/floor and stops chemical
from collecting in tube housing.
Spill recovery tube
drains solution
back to tank.
Partial hole is punched through
with a #2 Phillips head screwdriver.
1/4" plastic spill recovery tube is
inserted in hole. Use section of

Installation continued – suction line
INSTALL SUCTION LINE
1. Uncoil the suction line and cut a section
to assure that the end will be 2-3" above
the bottom of the solution tank. Use the
outside of the solution tank as a guide to
cut to proper length.
Allow sufficient slack to avoid kinks
and stress cracks. Always make a clean
square cut to assure that the suction
line is burr free. Normal maintenance
requires trimming.
Suction lines that extend to the bottom
of the tank can result in debris pickup
leading to clogged injectors and possible
tube failure.
2. Slide the suction line through the
connecting nut and ferrule and fully insert
the line into the bottom pump tube
fitting as indicated by the “IN” on the
tube housing cover.
3. Finger tighten nut to the threaded tube
fitting while holding the tube fitting.
Over tightening the ferrule and nut
with a wrench may result in damaged
fittings, crushed ferrules, and air pickup.
Do not use thread sealant tape on
pump tube connections or tools to
tighten connections.

Turn pump off when replenishing
solution.
Installation continued – discharge line
INSTALL DISHARGE LINE
1. Make a secure finger tight connection
on the discharge fitting of the pump
head as instructed in Install Suction
Line instructions.
Do not use thread sealant tape on pump
tube connections or tools to tighten
connections.
HAZARDOUS PRESSURE:
Shut off water or circulation system and bleed
off any system pressure.
Locate a point of injection beyond all
pumps and filters or as determined by
the application.
2. A 1/4" or 1/2" female NPT connection is
required for the injection fitting. If there
is no FNPT fitting available, provide one
by either tapping the pipe or installing
FNPT pipe tee fitting.
3. Wrap MNPT end of injection fitting
with 2 to 3 turns of threading tape. If
necessary trim straight-sided extension
tip so it is in the flow of water.
See Illustration

HAZARDOUS PRESSURE:
Shut off water or circulation system

The injection point and fitting require
periodic maintenance to clean any
deposits or buildup. To allow quick access
to the point of injection, Stenner
recommends the installation of shut-off
valves.
26-100 psi models:
• Prior to making tubing connection, test
check valve and NPT threads for leaks by
pressurizing system.
• Tighten an additional 1/4 turn if
necessary. Make final tube connection
as instructed in Install Suction Line
instructions.
0-25 psi models:
Low-pressure models do not have a check
valve and check valve body. Insert the
tubing 3/4" to 1" into the injection fitting
and make tubing connection as instructed
in Install Suction Line instructions.
5. Turn pump switch on and observe
chemical flow as actuated by system.
6. After a suitable amount of dosing time,
perform tests for required chemical levels.
If necessary, fine-tune dosing levels by
rotating dial ring (adjustable pumps only).

Tube Replacement – safety information
RISK OF CHEMICAL EXPOSURE:
To reduce risk of exposure, check the pump tube
regularly for leakage. At the first sign of leakage,
replace the pump tube.
To reduce risk of exposure, the use of proper personal
protective equipment is mandatory when working on or
near chemical metering pumps.
To reduce risk of exposure, and also prior to service,
shipping, or storage, pump generous amounts of
water or a compatible buffer solution to remove
chemical from pump.
Consult chemical manufacturer and MSDS sheet for
additional information and precautions for the chemical
in use.
Personnel should be skilled and trained in the proper
safety and handling of the chemicals in use.
PINCH POINT HAZARD:
Use extreme caution when replacing pump tube.
Be careful of your fingers and
fingers near rollers.
