serious personal injury, or major property damage if
ignored.
warns about hazards that can cause death,
serious personal injury, or major property damage if
ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
NOTICE indicates special instructions not related to
hazards.
Carefully read and follow all safety instructions in this
manual and on equipment. Keep safety labels in good con-
dition; replace if missing or damaged.
Incorrectly installed or tested equipment
may fail, causing severe injury or property
damage. Read and follow instructions in
owner's manual when installing and operating equipment.
Use equipment only in a pool installation.
Explosion hazard. This feeder is not
explosion proof. Do not install or use in an explosive
atmosphere.
DESCRIPTION
The SR-4000 and the SR-6000 are liquid dispensing systems for pool and spa applications consisting of a peristaltic pump, an interval timer and a duration timer. With
the flexibility of interval choices as well as duration adjustment, they are capable of handling a range of applications.
The SR-4000 is a single pump system. The SR-6000 is a
dual pump system, with a separate control board for each
pump. Either system can be plugged into a standard
115VAC electrical outlet with the cord provided or hardwired to 115VAC, 208VAC, or 230 VAC using the wiring
diagrams provided (See Figure 3, Page 3).
Figure 1: SR-4000 and SR-6000 chemical Feed
Systems.
Dispensers carrying the NSF seal are listed for swimming pools, spas and
hot tubs with the following chemicals:
12.5% SODIUM HYPOCHLORITE 10% HYDROCHLORIC ACID
80% NATURAL ENZYME
When proper materials are selected, they are capable of handling but not
limited to the following solutions:
12.5% ALUMINUM SULPHATE 5% SODIUM CARBONATE
2% CALCIUM HYPOCHLORITE 10% SODIUM HYDROXIDE

APPLICATION
Adding pool chemicals automatically on a regular basis will
minimize the high and low swings associated with intermittent manual chemical maintenance. By adding chemicals
automatically on a regular cycle, a more consistent level can
be achieved than is possible with weekly or semi-weekly
manual additions. The pump can lift 15 feet from the supply
tank, and push up to 20 feet vertically and 65-70 feet horizontally to the final injection point. Injecting into pressurized
lines up to 30 PSI is possible without special considerations.
The SR-4000 and SR-6000 can also be set on a continuous
setting and cycled by an automatic controller.
Risk of chemical burns and explosion.
Always consult the chemical manufacturer for
proper storage, use, handling and compatability for use
with a peristaltic pump.
Follow all warnings and instructions provided by the
chemical manufacturer.
Never dispense different chemicals through the
same supply tubing.
Always flush the pump and the supply tubing thoroughly with water prior to changing to another chemical.
Always inject chemicals into the return line downstream from all pool equipment.
Always wear protective clothing and face shield appropriate to the chemical(s) you are handling.
INSTALLATION
Mounting
Mount the SR-4000/SR-6000 Dispenser on a wall near the
chemical supply. The dispenser should be less than 15 feet
from the chemical container and less than 70 feet from the
injection point. Although further distances are possible,
performance may be reduced. Testing is recommended for
greater distances. Use appropriate hardware for the chosen
mounting surface. Mounting location should be protected
from exposure to direct spray and direct sunlight whenever
possible.
Plumbing
Connect the chemical tubing and drum kit following the
instructions included with the plumbing kit. Additional
tubing and hardware may be required depending on distances and configuration. Secure the injection point as required for either a pressure line or an open body of water.

Wiring
Chemical burn hazard.
This unit pumps one dose of chemicals when power
is first turned on to the pump. Connect all hoses and
start the main circulation pump before connecting power
to the chemical feed pump.
If this unit continues to operate when the circulator
pump is off, it will build up chemicals at the chemical feed injection point in the circulation system. If the
main circulation system is controlled by a timer, wire the
chemical feed pump through the same timer so that it
cannot operate when the circulator pump is off.
Make sure to have the SR-4000/SR-6000 power switch(s) in
the “OFF” position. The SR-4000/SR-6000 are factory wired
for 115VAC and are equipped with a standard 115VAC
power cord. If a 115VAC outlet is available, plug the cord
into the outlet. In the event 208VAC or 230VAC is required,
the system can be wired accordingly. See Figure 3.
Hazardous voltage (line voltage) in the control box when feeder is plugged in. Always unplug the
power cord(s) to the chemical feeder before opening the
enclosure for any reason except to prime the pump.
When priming the pump, do not put your finger or any
tools inside the control box. Do not attempt to work on,
service, or replace internal box components while the system is plugged in.
Refer to local electrical codes when supply is other then a
standard 115VAC outlet. A qualified electrician may be required for this conversion.
PCA CONTROL LAYOUT
The controls described in this manual refer to the components on the Printed Circuit Assembly (PCA). The PCA is
mounted on the inside of the door of the SR-4000/
SR-6000. To determine the location of these controls on
the PCA, please refer to Figure 4.
Set-up
When a known daily or weekly volume of chemical is required, calculations can determine the proper dose
amount and the interval between subsequent doses to
maintain a desired chemical level. The SR-4000/SR-6000
are factory set at 60 RPM and are equipped with 3cc per
revolution pump tubes. This set-up will deliver approximately 6 fluid ounces per minute per pump. Calibration
may be required to get a more exact rate. In most cases
there are several combinations of dosage times and intervals that achieve the same total daily chemical dose.
EXAMPLE: 24 doses/day at 1 oz./dose =24 oz./day just as
12 doses/day at 2oz/dose = 24 oz./day
