READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your system or in this manual, look for
one of the following signal words and be alert to the po-
tential for personal injury.

warns about hazards that will cause death, 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 condition; 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.

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

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).

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
