SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS PRIOR TO USE

Secure chemicals & metering pumps, making them inaccessible to children & pets.

*** DO NOT PUMP FLAMMABLE LIQUIDS.

*** Do not cut the plug or ground lug off the electrical cord. Consult a licensed electrician for proper installation or

replacement.

To reduce the risk of electrical shock-before maintenance, repair, or moving, always disconnect the power

to the pump by unplugging from wall outlet.

Always wear protective clothing, including gloves and safety glasses, when working on or near chemical

metering pumps.

** Inspect tubing regularly for cracking or deterioration and replace as necessary. (Always wear protective clothing and

safety glasses when inspecting tubing.)

** Use CAUTION to keep fingers away from rotating parts.

** If pump is exposed to direct sunlight, use a UV resistant tubing. ** Follow directions and warnings provided from the chemical manufacturer. The user is responsible for determining the

chemical compatibility with the chemical feed pump. ** Make sure the voltage on the pump name tag matches the installation voltage. If pump fails to start, check line voltage. ** Consult with local health officials and/or qualified water conditioning specialists when treating potable water. ** Always depressurize system prior to installation or disconnecting the metering pump tubing. ** If injection point is lower than the chemical tank and pump, install an anti-siphon valve.

** DO NOT MODIFY PUMP. This poses a potentially dangerous situation and will void the warranty. Hand tighten plastic

connections (Do not use wrench).

All pumps are factory tested with water. Remove tubing and thoroughly dry if the chemical being pumped

will react with water (for example sulfuric acid).

* Hand tighten plastic connections (Do not use wrench).

* Consult licensed plumber and electrician before installation to conform to local codes.

* NOTE: For accurate volume output, pump must be calibrated under all operating conditions.

INTRODUCTION

Series 100/150 are diaphragm-type metering pumps. A fluid is pumped from a chemical storage tank to the point of injection by the pulsing action of the diaphragm. The four check valves (top and bottom of pump head, strainer assembly, and injection assembly) keep the fluid flowing toward the point of discharge. To insure the solution being pumped can only go forward, it is important that all check valves provide positive, non-leaking backflow prevention. The wetted end (those parts that contact the solution being pumped) is constructed of SAN, PVC, TFE, Hypalon®, and polyethylene. These materials are very resistant to most chemicals. However, there are some chemicals, such as strong acids or organic solvents, which cause deterioration of some elastomer and plastic parts, such as diaphragm, valve seat, or head. Alternate materials such as Viton®, polypropylene is available on request. Contact chemical supplier for chemical compatible materials.

PRECAUTIONS FOR OPERATION

Each Series 100/150 chemical feeder has been tested to meet prescribed specifications and certain safety standards. However, a few precautionary notes should be adhered to at all times. THOROUGHLY READ ALL CAUTIONS PRIOR TO INSTALLING METERING PUMP.

1. Chemicals used may be dangerous and should be used carefully and according to warnings on the label. Follow the directions given with each type of chemical. Do not assume chemicals are the same because they look alike. Always store chemicals in a safe location away from children and others. We cannot be responsible for the misuse of chemicals being fed by the pump.

2. Always wear protective clothing (protective gloves and safety glasses) when working on or near chemical metering pumps.

3. Tampering with electrical devices can be potentially hazardous. Always place chemicals and feeder installation well out of the reach of children and others.

4. Be careful to check that the voltage of the installation matches the voltage indicated on the specification label. Each pump is equipped with a three prong plug. Whether plugging into a receptacle or wiring into a system, always be sure the feeder is grounded. If receptacle is utilized, to disconnect, do not pull wire but grip the plug with fingers and pull out.

5. Never repair or move the metering pump while operating. Always disconnect electrical current. Before handling the pump always allow sufficient time for the motor housing to cool off. Handling the pump too soon after shutdown may cause hand burns. For safety use protective gloves.

6. All pumps are pretested with water before shipment. Remove head and dry thoroughly if you are pumping a material that will react with water, (e.g. sulfuric acid). Valve seats, ball checks, gaskets, and diaphragm should also be dried. Before placing feeder into service, extreme care should be taken to follow this procedure.

7. Arrows on the pump head and injection fitting indicate chemical flow. When properly installed, these arrows should be pointing upward.

8. When metering hazardous material DO NOT use plastic tubing. Strictly use proper rigid pipe. Consult supplier for special adaptors.

9. Pump is NOT to be used to handle or meter flammable liquids or materials.

10. Standard white polyethylene discharge tubing is not recommended for installations exposed to direct sunlight. Consult supplier for special black polyethylene tubing.

11. Manufacturer will not be held responsible for improper installation of pumps, or local plumbing conducted. All cautions are to be read thoroughly prior to hook-up and plumbing. For all installations a professional plumber should be consulted. Always adhere to local plumbing codes and requirements.

12. Note the maximum pressure rating of the metering pump. When used with pressurized systems, always be sure the pressure of the system does not exceed maximum pressure rating listed on the specification label.

13. Be sure to depressurize system prior to hook-up or disconnection of metering pump.

INSTALLATION, PIPING AND WIRING

UNPACKING, ASSEMBLING AND MOUNTING:

The carton should contain:

 Metering Pump  4 ft. (1.21 m) Clear Flexible Suction Tubing  4 ft (1.21 m) Stiff White Return Tubing  Feeder can be mounted on a wall shelf bracket

(Figure B), tank stand platform (Figure C), directly on the wall (Figure D), or directly on the tank cover (Figure E).

 Bleed Valve Assembly  Instructions  Strainer Assembly w/Tube Weight  Back Check Valve Assembly  8 ft (2.43 m) Stiff White Discharge Tubing

(Optional black tubing for UV protection available from the factory)

To mount the feeder directly on the wall, place the feeder base against the wall with the motor below the pumping head, remove four head mounting bolts, and turn head quarter turn so suction is in bottom position.

IMPORTANT: Injection point must be higher than top of solution tank to prohibit gravity feeding. Maximum head in meters is 70m/H2O for Series 100 Model pumps and 42m/H2O for Series 150 Model pumps.

NOTE: Make sure the arrow on the outside of the pump head is pointing upward. The pump must be positioned so that the plug is accessible.

Flooded suction mounting Fig. C (installing feeder at the base of tank on a platform) is the most trouble free type of installation. (Tank stands and platforms are available for all size feeders and tanks). The pump is secured on the platform, and then the clear suction tubing is attached to a bulkhead fitting assembly and the suction valve housing on the pump head. Since the suction tubing is always filled with solution, priming is accomplished much more quickly and the chance of losing prime on an installation where the feeder is used only a few hours a day, is greatly reduced. The feeder comes with a bleed valve assembly that attaches to the discharge valve in the pump head. The bleed valve allows you to manually prime the feeder and depressurize the discharge line without disconnecting the feeder from the tubing connections.

NOTE: To operate without bleed valve, replace bleed

valve (item #49) and 0.38 in. (0.96 cm) -tubing size discharge valve housing (item # 42) with a 0.50 in. (1.27 cm) -tubing size discharge valve housing (item #42) and coupling nut (item #43). See page 12 (Wet End Assembly). Items #42 and #43 are available from factory.

Assemble tubing and fittings to the feeder (Fig. G).

Do not force fittings, HAND TIGHTEN ONLY. Do not use additional sealants, such as pipe tape, on

tubing fittings. Use additional sealants, such as pipe tape, on pipe fittings and tighten normally.

If water is used to dissolve solid chemicals or create a dilute solution, the chemical tanks should be manually filled or an approved means must be used to prevent a cross connection between the chemical tank contents and the potable water line. Check local plumbing regulations.

CHEMICAL INJECTION:

Chemical injection into an open tank: The discharge tubing can be placed in an open tank with or without the injection valve assembly. Each feeder is shipped with a spring loaded back check injection valve. This assists in a positive seal on the discharge side of the pump head preventing back flow.

Pumps carrying the 'NSF' or the 'ETL Sanitation' (tested to NSF standard-50) approval are listed for swimming pools, spas, and hot tubs, and when proper materials are selected, are capable of handling but not limited to the following chemical solutions.

121/2% sodium hypochlorite 2% calcium hypochlorite 12% aluminum sulfate 10% hydrochloric acid 10% sodium hydroxide 5% sodium carbonate.

INSTALLATION INTO A WELL PUMP SYSTEM:

Make sure the voltage of the feeder matches the voltage of the well pump. Install the injection fitting into a tee which is installed into

the water line going to the pressure tank. The end of the injection check valve should be in the main stream of the water line. A typical

installation is shown in Figure H. For installation of pump for

operating swimming pools, pump is to be supplied by an isolating transformer or thru an "RCD" (residual current device).

NOTE: It is recommended to install the injection assembly in a vertical position on the bottom side of the water line (Figure J).

This will insure proper sealing of the injection assembly check valve and prevent a back flow into the feeder's discharge line. Be sure arrow on injection fitting is pointing upward.
