1. Introduction
This instruction manual provides essential information for the proper installation, operation, and maintenance of the Angel Flo Master XP2 Pump Impeller, model 91694150. This impeller is a critical component designed for Aqua-Flo XP/XP2 series pumps, responsible for generating the necessary water pressure for your spa or pool system. Adhering to these instructions will ensure optimal performance and longevity of the product.
2. Product Overview
The Angel Flo Master XP2 Pump Impeller (Model 91694150) is a closed-face impeller specifically engineered for 1.5 Operational Horsepower (OHP) and 2.0 Total Horsepower (THP) Aqua-Flo XP/XP2 series spa pumps. It is constructed from durable ABS material, designed to withstand the demands of continuous water circulation in spa and pool environments.

3. Safety Information
Always observe the following safety precautions when handling or installing the impeller:
- Disconnect Power: Before attempting any installation, maintenance, or repair, ensure that the main power supply to the pump is completely disconnected at the circuit breaker. Failure to do so can result in serious injury or electrical shock.
- Professional Installation Recommended: If you are unfamiliar with pump mechanics or electrical systems, it is highly recommended to seek assistance from a qualified technician.
- Wear Protective Gear: Use appropriate personal protective equipment, such as gloves and eye protection, during installation or maintenance.
- Handle with Care: Impellers may have sharp edges. Handle the component carefully to prevent cuts.
- Ensure Proper Drainage: Before opening the pump housing, ensure the pump and associated plumbing are fully drained to prevent water spillage and potential electrical hazards.
4. Installation
The following steps outline the general procedure for replacing an impeller in an Aqua-Flo XP/XP2 series pump. Specific pump models may vary slightly. Refer to your pump's specific manual for detailed disassembly instructions.
- Preparation:
- Turn off all power to the pump at the main breaker.
- Drain the pump and plumbing system completely.
- Place a towel or container beneath the pump to catch any residual water.
- Disassembly:
- Remove the wet end of the pump from the motor. This typically involves unbolting the volute (pump housing) from the motor assembly.
- Carefully remove the old impeller. This may require a specialized tool or a firm grip and counter-clockwise rotation, often while holding the motor shaft stationary from the rear. Note the orientation of any washers or seals.
- Inspect the pump seal and replace it if necessary. A new seal is often recommended when replacing an impeller.
- Impeller Installation:
- Thread the new Angel Flo Master XP2 Impeller onto the motor shaft by turning it clockwise until it is hand-tight. Ensure it seats properly.
- Do not overtighten, as this can damage the impeller or motor shaft.
- Reassembly:
- Reattach the pump wet end to the motor, ensuring all gaskets and O-rings are correctly seated.
- Tighten all bolts evenly to prevent leaks.
- Reconnect any plumbing and electrical connections that were removed.
- Testing:
- Before restoring full power, ensure the pump is primed with water according to your pump's instructions.
- Restore power and carefully observe the pump for proper operation and any leaks.
5. Operation
The impeller itself does not have operational controls; it functions as an internal component of the pump. Once installed correctly within the Aqua-Flo XP/XP2 pump, it will begin to rotate with the motor, drawing water into the pump's center and expelling it outwards through centrifugal force, thereby generating water pressure and flow for your spa or pool system. Proper pump operation relies on a correctly installed and undamaged impeller.
6. Maintenance
Regular inspection and maintenance of your pump system, including the impeller, can extend its lifespan and ensure efficient operation:
- Visual Inspection: Periodically inspect the impeller for signs of wear, cracks, or debris accumulation. A damaged impeller can lead to reduced pump performance or failure.
- Debris Removal: If the pump is disassembled for other maintenance, gently clean any debris from the impeller vanes. Avoid using harsh chemicals or abrasive tools that could damage the ABS material.
- Seal Integrity: Always check the pump seal when the impeller is exposed. A worn or damaged seal can cause leaks and affect pump efficiency.
- Winterization: During winterization, ensure the pump is completely drained to prevent freezing water from damaging the impeller or pump housing.
7. Troubleshooting
If you experience issues with your pump after impeller installation, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Pressure/Flow |
|
|
| Pump Making Unusual Noise |
|
|
| Water Leaking from Pump |
|
|
If problems persist after attempting these solutions, contact a qualified pump technician.
