To reduce risk of electrical shock, connect only to a properly
grounded, grounding type receptacle.
RISQUE DE CHOC ELECTRIQUE:
Cette pompe est équipée d’une fiche de mise à terre. Pour
réduirele risque de choc électrique, s’assurer que la fiche est
bien raccordée à une prise de courant avec une connexion de
mise à terre.
DO NOT alter the power cord or plug end.
DO NOT use receptacle adapters.
DO NOT use pump with a damaged or altered power
cord or plug. Contact the factory or an authorized service facility
for repair.
HAZARDOUS VOLTAGE:
DISCONNECT power cord before removing motor cover for
service. Electrical service by trained personnel only.
EXPLOSION HAZARD:
This pump is not explosion proof. Do Not install or operate in
an explosive environment.
RISK OF CHEMICAL EXPOSURE:
Potential for chemical burns, fire, explosion, personal injury, or
property damage. To reduce risk of exposure, the use of proper
personal protective equipment is mandatory.
RISK OF FIRE HAZARD:
Do Not install or operate on any flammable surface.
RISK OF CHEMICAL OVERDOSE:
To reduce risk, follow proper installation methods and
recommendations. Check your local codes for additional
guidelines.
AVERTISSEMENT
Warns about hazards
that CAN cause death, serious personal injury,
or property damage if ignored.

Safety Information continued
Warns about hazards that WILL or CAN
cause minor personal injury or property damage if ignored.
PLUMBING:
NOTICE: Indicates special instructions or general
mandatory action.
NOTICE: This metering pump is portable and designed
to be removable from the plumbing system without
damage to the connections.
NOTICE: This metering pump and its components
have been tested for use with the following chemicals:
Sodium Hypochlorite (10-15%), Muriatic Acid (20-22
Baume, 31.5% Hcl), and Soda Ash.
NOTE: Cette a pompe de dosage et ses composants ont
été testés pour utilisation avec les produits chimiques
suivants; Hypochlorite de Sodium (solution de 10-15%);
Acide Muriatique (20-22 Baume, 31.5% Hcl); Cendre
de Soude.
This is the safety alert symbol. When displayed in
this manual or on the equipment, look for one of the
following signal words alerting you to the potential for
personal injury or property damage.
PUMP SUITABLE FOR USE OUTDOORS when installed
with a Stenner Rain Roof Part No. MP90000.
Electrical installation should adhere to all national and local
codes. Consult a licensed professional for assistance with proper
electrical installation.
Removing power from pool/spa recirculation pump must
also remove power from pump.
The use of an auxiliarysafety device (not supplied), such as
aflow switch or sensor,is recommended to prevent feed pump
operation in the event of a recirculation pump failureor if flow
is not sensed.
Point of chemical injection should be beyond all pumps,
filters, and heaters.
PUMP INTENDED FOR INDOOR USE.
Cette pompe est prévue pour utilisation à l’intérieur.
Chemical feed pump installation must always adhere to your
local plumbing codes and requirements. Be sure installation does
not constitute a cross connection. Check local plumbing codes
for guidelines.

Outputs 100 MDC series
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.

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 170MDCHP34
• Decide on the desired output for the inner head.
• Note the setting on the dial ring that represents the
desired output.
For example setting #8 = 80% of max output
In the 170MDCHP34 model, setting
#8 = 13.6 GPD
• Repeat the above steps to calculate the output of the
outer head.
Using setting #6 in this example,
#6 = 60% of the inner head output
13.6 GPD x 60% = 8.5 GPD
In this example using pump model 170MDCHP34, the
output for the inner head would be 13.6 GPD and
8.5 GPD for the outer head.

Installation – additional safety instructions
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.
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.
NOTICE: Indicates special instructions or general mandatory action.

US and Canada call 1-800-683-2378, other countries call 1-904-641-1666 19
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
apump 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-offvalve or other device
must be provided to stop flow to pump
during service.
• Use the mounting bracket as a template
to drill pilot holes in mounting location.
• 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.
• Plug cord into receptacle and turn the
motor power switch on. If the pump is
adjustable, turn the dial ring to 10.
• Activate the pump by the pump control
(flow switch, pressureswitch, etc.) and
verify rotation of the roller assembly
within the clear pump head. Turn pump
switch off.
