This document is an owner's manual for STA-RITE 60 Cycle "AN" Series Shallow Well Jet Pumps and Water Systems. It provides installation, operating instructions, and repair parts lists for various models ranging from 1/3 HP to 1-1/2 HP.
Function Description:
The STA-RITE "AN" Series pumps are designed for shallow well applications, drawing water from a well or other water sources and delivering it under pressure for domestic use. They are available as standalone pumps or as part of a complete water system when mounted on a pressure tank. The pumps are designed to handle water from cased wells, point-driven installations, dug wells, or lakes.
Important Technical Specifications:
The manual covers a range of models with different horsepower ratings:
- 1/3 HP: ANB-30L, ANB12H-30, ANB30H-30, ANB42CA-30
- 1/2 HP: ANC-30L, ANC12H-30, ANC30H-30, ANC42CA-30
- 3/4 HP: AND-30L, AND30H-30, AND42CA-30
- 1 HP: ANE-30L
- 1-1/2 HP: ANF-30L
Electrical Specifications (115/230 Volts):
- 1/3 HP: Max. Load Amp 9.4/4.7, Branch Fuse Rating 15/15 Amp
- 1/2 HP: Max. Load Amp 8.8/4.4, Branch Fuse Rating 15/15 Amp
- 3/4 HP: Max. Load Amp 12.2/6.1, Branch Fuse Rating 20/15 Amp
- 1 HP: Max. Load Amp 14.8/7.4, Branch Fuse Rating 20/15 Amp
- 1-1/2 HP: Max. Load Amp 19.2/9.6, Branch Fuse Rating 25/15 Amp
The manual provides a detailed wiring chart (Table II) for recommended fusing and wiring data based on distance from motor to supply, specifying AWG wire sizes for distances up to 500 feet. Dual element or Fusetron time delay fuses are recommended for all motor circuits.
Piping Specifications (Table I - Horizontal Distance Between Shallow Well Jet Pump and Well):
Recommended correct pipe sizes vary with pump HP and horizontal distance:
- 1/3 - 1/2 HP: 1-1/4" for 25-250 ft, 1-1/2" for 300 ft.
- 3/4 HP: 1-1/4" for 25-100 ft, 1-1/2" for 150-250 ft, 2" for 300 ft.
- 1 HP: 1-1/4" for 25 ft, 1-1/2" for 50-150 ft, 2" for 200-300 ft.
- 1-1/2 HP: 1-1/4" for 25 ft, 1-1/2" for 50-150 ft, 2" for 200-300 ft.
Usage Features:
- Installation Flexibility: Can be installed in cased wells, point-driven installations, dug wells, or lakes.
- Priming: Requires filling the pump with water before initial startup. For models up to 3/4 HP, a 4" vertical nipple in the suction tapping aids in completely filling the pump body.
- Pressure Tanks: Can be used with various tank types, including standard horizontal tanks and STA-RITE Con-Aire® tanks. Con-Aire® tanks feature a permanent precharge of air, eliminating the need for an air volume control.
- Air Volume Control: For standard horizontal tanks, an air volume control is used to add air as needed. Atmospheric charging is an alternative method for horizontal tanks to maintain a minimum air cushion.
- Safety Warnings: Emphasizes never running the pump dry or against a closed discharge to prevent damage, overheating, and potential injury. Electrical warnings highlight the risk of shock and the importance of proper grounding and matching motor voltage to supply voltage.
Maintenance Features:
- Shaft Seal Replacement: Detailed instructions are provided for removing the old shaft seal (rotating part and ceramic seat) and installing a new one. This involves unscrewing the impeller, prying off the rotating part, and pushing out the ceramic seat. Installation requires cleaning surfaces, lubricating the ceramic seat with soapy water, and carefully reassembling the components.
- Lubrication: The pump and motor are designed for minimal maintenance; the motor has shielded ball bearings lubricated for life, and the mechanical shaft seal is self-lubricating.
- Troubleshooting Guide: A comprehensive section addresses common issues such as:
- Motor Will Not Run: Checks for switch, fuse, shaft freedom, motor starting switch, wiring, motor burnout, and pressure switch issues.
- Motor Runs But No Water Is Delivered: Addresses priming, leaky suction pipes, clogged foot valves/strainers, clogged ejector nozzles, improper pipe pitch, and low water levels.
- Pump Does Not Deliver To Full Capacity: Covers low water levels, clogged ejector nozzles, leaky connections, corroded pipes, undersized offset lines, clogged foot valves/strainers, and low motor speed.
- Pump Will Not Shut Off: Checks for pressure switch adjustment, clogged ejector nozzles, low water level, leaky pipes, and low motor speed.
- Pump Starts and Stops Too Often: Addresses waterlogged pressure tanks, leaks in piping, leaky foot valves, pressure switch adjustment, and leaks in the pressure tank.
- Motor Runs Hot and Overload Kicks Out: Covers incorrect wiring, low voltage, poor ventilation, and frequent starting/stopping.
- Pump Is Noisy: Suggests mounting the pump on a concrete or substantial sub-base.
- Air Spurts From Faucets: Points to airlogged pressure tanks or leaks in the suction side of the pump.
- Repair Parts Lists: Exploded views and detailed parts lists are provided for 1/3 thru 3/4 HP models (Figure 5) and 1 and 1-1/2 HP models (Figure 6), including part numbers for motors, seals, impellers, diffusers, pump bodies, venturis, nozzles, plugs, fittings, pressure switches, and service kits (Seal and Gasket Kit, Overhaul Kit).
- Tank Group Parts Lists: Separate parts lists are included for "AN" Series pumps on horizontal tanks (Figure 10) and Con-Aire® tanks (Figure 11), detailing components like tanks, hose clamps, hoses, elbows, fittings, air volume controls, and mounting hardware.
Warranty:
STA-RITE provides a limited warranty to the original consumer against defects in material and workmanship.
- Water Systems Products (jet pumps, small centrifugal pumps, submersible pumps, and related accessories): 1 year from original installation or 2 years from manufacture (whichever occurs first).
- Con-Aire® tanks: 5 years from original installation.
- Epoxy-Line Tanks: 3 years from original installation.
- Environmental Products: 1 year from original installation or 2 years from manufacture (whichever occurs first).
The warranty is void if the product has been subject to negligence, misapplication, improper installation, or maintenance. Operating a three-phase submersible motor with single-phase power through a phase converter or without recommended overload relays also voids the warranty. The buyer's sole remedy is repair or replacement of defective products, with the buyer responsible for labor and shipping charges. The warranty does not cover consequential, incidental, or contingent damages.
