WIRING

1. : Risk of electrical shock. This pump is supplied with a three prong grounding type power plug.

To reduce risk of electric shock, connect only to a properly grounded, grounding type receptacle.

2. The metering pump should be wired to an electrical source which conforms to those on the pump nameplate.

(Applying higher voltage than the pump is rated for will damage the internal circuit.)

3. In the electronic circuit of the control unit, measures for surge voltage are made by means of surge absorbing

elements and high voltage semiconductors. Nevertheless, excessive surge voltage may cause failure in some areas.

Therefore, the receptacle should not be used in common with heavy electrical equipment which generates high

voltage. If this is unavoidable, however, measures should be taken by (a) the installation of a surge absorbing

element (varistor of min. surge resistance 2000A) to the power supply connection of the pump, or (b) the installation of

a noise suppression transformer.

4. In the event of electrical power interruption during pump operation, the pump will remember its setting and

automatically resume operation as before, whenever power is restored. If a manual reset is required to resume

operation, the electrical circuit serving the pump must be suitably wired. Latching power relays which "drop out" upon

loss of power, requiring manual reset, are typically used for this purpose.

WELL PUMP SYSTEM INSTALLATION

1. Ensure that the metering pump voltage matches the voltage of the well pump.

Typical well pump electrical circuits are shown in Figure J. All electric wiring

should be installed in accordance to local electrical codes by a licensed

electrician.

2. Install the backpressure/injection (Figure I) on the discharge side of the

metering pump into a tee which is installed into the water line going to the

pressure tank. Typical installations are found in figures G1, G2 and G3.

Pumps carrying the "ETL Sanitation' approval (tested to NSF standard 50) 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:

12% ALUMINUM SULPHATE 5% SODIUM CARBONATE

10% SODIUM HYDROXIDE 2%CALCIUM HYPOCHLORITE

12.5% SODIUM HYPOCHLORITE 10% HYDROCHLORIC ACID
