SIZING IN GALLONS
Pre-Programming Requirements
A. Determine the Maximum System Flow Rate or Well Pump Flow Rate in Gallons
per Minute.
If well pump output is unknown, refer to example below:
Calculate well pump output rate (gpm).
Determine the output rate by opening a faucet until the well pump turns on.
Immediately turn off the faucet and time how long the well pump runs. Next,
measure the volume of water drawn from the faucet until the well pump turns
on again.
Volume of water until the pump turns on (gallon) =Well Pump Output Rate
How long the pump runs (min.) (gpm)
B. Determine Solution Strength Percentage and the Dosage Requirement in Parts
per Million.
If dosage is unknown, refer to example below:
Calculate required dosage (ppm).
Refer to Oxidation Rates below. Estimate dosage and include the ppm of
required residual.
10 gallons = 5 gpm
2 minutes
Example: After drawing 10 gallons of water,
the well pump took 2 minutes to fill the
pressure tank and stop.
Common Chemical Solution Strengths in ppm
Name % ppm
Sodium Hypochlorite 5.25 52,500
6.125 61,250
12.5 125,000
Potassium Permanganate Dissolved at 1/4 lb per gallon 3 30,000
Hydrogen Peroxide 7 70,000
Polyphosphate Dissolved at 1 lb per 10 gallons 1.2 12,000
Oxidation Rates
For each ppm of Iron Manganese Hydrogen Sulfide
Required ppm of Chlorine 12 3
Required ppm of Hydrogen Peroxide 0.5 1 1.5
2 ppm iron x 1 ppm chlorine = 2
4 ppm hydrogen sulfide x 3 ppm chlorine = 12
1 ppm chlorine residual = 1
Total 2 + 12 + 1 = 15 ppm
Example: To treat a water supply containing
2 ppm iron and 4 ppm hydrogen sulfide
with a chlorine residual of 1 ppm, a dosage
15 ppm of chlorine is required.

2. Calculate the PCM Operating Time in Seconds.
Calculate the PCM Operating Time based on pump selection in D, solution and dosage
in B and use the formula below.
Pump Output Requirement (gpd) x Available Dose Time (sec.) =PCM Operating
Pump’s Maximum Output (gpd) Time (sec.)
PCM OPERATING TIME EXCEEDING AVAILABLE DOSE TIME
MAY LEAD TO DOSING ERRORS. To reduce PCM Operating Time, select a pump with
a higher output or use stronger solution strength.

INSTALLATION
Mount PCM in a dry location to avoid water intrusion and damage.
1. Position the PCM within 6 feet of the Stenner fixed output metering pump and mount
to a suitable surface using adequate fasteners through the mounting holes.
Check supply voltage prior to connecting power cord to prevent damage. The use
of a GFCI circuit is recommended.
2. Uncoil the input signal cable and remove approximately 2 inches of the outer
cable jacket.
DO NOT connect PCM input signal cord to any AC voltage supply.
DO NOT connect PCM input signal cord to any hall effect, 4-20mA or voltage
carrying signal source.
3. Strip the ends of the two wires within the cable approximately one-half inch.
Use PCM only with a dry contact, reed switch style water meter.
4. Attach the two wires to the contact output water meter or relay switch.
5. Adjust the knob to the desired on-time duration. Refer to the “Sizing” in this manual
for assistance.
If using an adjustable metering pump, it is recommended that the pump be set
at 100%.
6. With necessary suction, discharge and point of injection connections secured,
prime the pump by plugging it into a 120V receptacle and turning on the power
switch.
7. Unplug the fixed output metering pump’s power cord from receptacle and plug into
the PCM’s receptacle.
8. Plug the PCM power cord into a properly grounded, 120V receptacle.

TROUBLESHOOTING
LACK OF INPUT SUPPLY VOLTAGE (120V)
Plug the fixed output chemical metering pump directly into the 120V receptacle into which
the PCM was originally plugged. This will bypass the PCM. If the pump does not run, the
power source or pump is defective. If the metering pump operates, proceed to LACK OF
PROPER INPUT SIGNAL.
LACK OF PROPER INPUT SIGNAL
Plug the metering pump into the PCM and the PCM into the receptacle tested in Step I.
Remove the PCM input signal cable from the water meter or relay and touch the two wires
together. The pump should operate for the pre-determined run time setting and then stop.
• If the metering pump runs, the failure is in the water meter contacts.
• If the metering pump does not run, the failure is in the PCM.
• Contact the factory for information on service and repair.

HAZARDOUS VOLTAGE
DISCONNECT power cord before removing cover for service. Electrical service by
trained personnel only.
The PCM operating range is factory set according to the specific model. The operating
range can be changed to convert a PCM to any of four available operating ranges without
purchasing another model.
The operating range is converted by changing the position of the jumpers on the printed
circuit board located under the PCM’s cover. Illustration A. The PCM is equipped with two
jumpers that are positioned over the pins labeled 3, 2, 1. Illustration B.
To change the time range:
1. Unplug the PCM power cord from the input power supply.
2. Remove the cover and reposition the jumpers to correspond with the desired
operating range. Refer to Interchangeable Operating Range Settings below.
3. Replace the PCM cover.
4. IMPORTANT! Update the PCM data label to represent the converted model and
operating range for accurate sizing.
