Model: AJm110H

1. Introduction

Thank you for choosing the KEYAYEYA AJm110H Booster Jet Pump. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your pump. Please read this manual thoroughly before attempting to install or operate the pump. Keep this manual in a safe place for future reference.

2. Product Overview

The KEYAYEYA AJm110H is a self-priming, high-head booster jet pump designed for single-phase 220V electrical systems. It is suitable for various applications requiring reliable water pressure boosting, such as domestic water supply, small-scale irrigation, and industrial uses. Its self-priming capability allows it to draw water from depths without requiring manual priming after initial setup.

3. Safety Information

WARNING: Failure to follow these safety instructions could result in electric shock, fire, serious injury, or death.

  • Always disconnect power before performing any installation, maintenance, or repair work on the pump.
  • Ensure the electrical supply matches the pump's requirements (220V, single-phase).
  • All electrical connections must be performed by a qualified electrician and comply with local codes and regulations.
  • Do not operate the pump with damaged cables or plugs.
  • Protect the pump from freezing temperatures. Drain the pump if it will be exposed to freezing conditions.
  • Do not run the pump dry. Dry running can cause severe damage to the pump.
  • Ensure proper ventilation around the pump to prevent overheating.
  • Keep children and unauthorized personnel away from the pump during operation.

4. Setup & Installation

4.1 Pre-Installation Checks

  • Location: Choose a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. The pump should be installed as close to the water source as possible.
  • Foundation: Mount the pump on a solid, level surface to minimize vibration and noise. Use appropriate bolts to secure it.
  • Power Supply: Verify that the available power supply is 220V, single-phase, and has adequate current capacity for the pump.

4.2 Plumbing Connections

  • Suction Line: Use a rigid, airtight pipe for the suction line. The diameter should not be smaller than the pump's suction port. Install a foot valve with a strainer at the end of the suction pipe in the water source to prevent debris from entering the pump and to maintain prime.
  • Discharge Line: Connect the discharge pipe to the pump's outlet. Install a check valve on the discharge side to prevent backflow, especially in systems with high static head.
  • Ensure all connections are sealed properly to prevent air leaks, which can affect the pump's self-priming ability.

4.3 Electrical Connections

  • All electrical wiring must be performed by a licensed electrician.
  • Connect the pump to a dedicated 220V, single-phase circuit protected by a suitable circuit breaker or fuse.
  • Ensure proper grounding of the pump to prevent electrical hazards.
  • Refer to the wiring diagram provided on the pump's motor label for correct connections.

4.4 Priming the Pump

Before initial startup, the pump must be primed:

  1. Remove the priming plug located on the top of the pump casing.
  2. Fill the pump casing completely with clean water until it overflows from the priming port.
  3. Replace and tighten the priming plug securely.
  4. Open any valves on the discharge side to allow air to escape during startup.

5. Operating Instructions

5.1 Initial Startup

  1. Ensure the pump is properly primed (see Section 4.4).
  2. Verify all plumbing connections are tight and leak-free.
  3. Open the discharge valve fully.
  4. Switch on the power supply to the pump. The pump should start and begin to draw water.
  5. Allow the pump to run for a few minutes to ensure all air is expelled from the system and a steady flow is established.

5.2 Normal Operation

  • Monitor the pump for unusual noises or vibrations.
  • Ensure the pump is not running dry. If the water source runs out, immediately switch off the pump.
  • Maintain adequate water levels in the source to prevent cavitation.

5.3 Shutdown Procedures

  • To stop the pump, simply switch off the power supply.
  • If the pump will be out of service for an extended period or during freezing weather, drain the pump completely to prevent damage.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump. Always disconnect power before performing any maintenance.

6.1 Routine Checks (Monthly)

  • Inspect for any visible leaks around connections and seals.
  • Check for unusual noises or excessive vibration during operation.
  • Ensure the motor is not overheating.
  • Clean the foot valve strainer in the water source to prevent clogging.

6.2 Winterization

If the pump is installed in an area subject to freezing temperatures, it must be drained to prevent damage:

  1. Disconnect power to the pump.
  2. Open the drain plug(s) on the pump casing and remove the priming plug to allow all water to drain out.
  3. Disconnect the suction and discharge lines if necessary to ensure complete drainage.
  4. Store the pump in a warm, dry place if possible, or ensure it is completely dry before re-installing plugs.

7. Troubleshooting

Before attempting any repairs, always disconnect the power supply to the pump.
