Installation Notes

⚠️ Pump must be installed below water level (flooded suction) to ensure proper priming.

⚠️ Never run pump dry – this will cause mechanical seal damage and void the warranty.

⚠️ Ensure proper grounding and bonding per NEC requirements.

⚠️ GFCI protection is required by code for all hot tub and spa installations.

⚠️ This pump does not include a power cord. Use your existing AMP-style pump cord or purchase a compatible replacement. For 2-speed operation, a 4-pin AMP cord is required.

⚠️ The discharge position can be rotated by loosening the four long thru-bolts at the back of the motor and rotating the wet end to the desired position (3, 6, 9, or 12 o’clock).

💡 Tip: This pump is designed as a direct drop-in replacement for Aqua-Flo XP2e and similar 48-frame pumps. If replacing an existing pump, note the wire connections or take a photo before disconnecting for easier reconnection.

🔧 Maintenance Guide

Routine Maintenance

Task	Frequency	Notes
Check for leaks	Monthly	Inspect around seal area and union connections
Inspect unions	Monthly	Tighten if needed – hand-tight plus 1/4 turn
Clean strainer/filter	As needed	Remove debris that may restrict water flow
Check amperage draw	Annually	Should match rated 10.0A (high) / 3.0A (low)
Inspect motor vents	Quarterly	Keep clear of debris for proper cooling
Check mounting bolts	Quarterly	Tighten if loose from vibration
Inspect drain plugs	Quarterly	Ensure no seepage at 3, 6, 9 o’clock positions

Warning Signs – Replace Pump If:

• Unusual noise (grinding, screeching, or humming without rotation)
• Water leaking from the mechanical seal area
• Motor trips the circuit breaker repeatedly
• Noticeably reduced water flow through jets
• Motor runs excessively hot or overheats frequently
• Visible rust or corrosion on the motor housing

Mechanical Seal

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: This pump is rated at 2.0 HP. In the spa industry, pumps may be marketed with different HP values based on the measurement method used (input power, output power, competitive/peak ratings). The rated horsepower of 2.0 HP is the industry-standard specification for pump comparison and selection.

Q: Will this fit my hot tub? A: This pump has a 48 Frame (Thru-Bolt) motor with 2-inch MBT connections on both suction and discharge. It is a common replacement for Aqua-Flo XP2e, Balboa/Dura Jet, and Waterway pumps with matching specifications. Check your existing pump’s frame type (48 or 56), voltage (115V or 230V), port size (2″), and speed configuration (1-speed or 2-speed) to confirm compatibility.

Q: What voltage does this pump require? A: 230V / 60Hz. All electrical installation must be performed by a licensed electrician. Verify your existing pump’s voltage before ordering – using the wrong voltage will damage the motor.

Q: Is this a single or dual speed pump? A: This is a 2-speed pump. High speed (10.0A) provides powerful jet action for massage, while low speed (3.0A) runs quietly for filtration and water circulation. It can also be wired for single-speed operation if needed.

Q: What size are the ports? A: Both the suction (center intake) and discharge (side) ports are 2-inch Male Buttress Thread (MBT). The outside thread-to-thread measurement is approximately 3-1/16 inches, which connects to standard 2-inch inner diameter spa plumbing using pump unions.

Q: Does it come with unions? A: Yes, two 2-inch unions are included with the pump for easy installation.

Q: Can I rotate the discharge direction? A: Yes. The discharge port ships in the 12 o’clock position and can be rotated to 3, 6, or 9 o’clock by loosening the four thru-bolts at the back of the motor and rotating the wet end.

Q: What warranty is included? A: This pump includes a 1-year manufacturer’s limited warranty. The motor serial number label (located on the outside of the motor housing) is required for all warranty claims. Contact Parts4Tubs for full warranty terms and support.

Q: How do I know if my pump needs replacing? A: Common signs include unusual noise (grinding, screeching), water leaking from the seal area, reduced jet flow, the motor tripping the circuit breaker repeatedly, or the motor running excessively hot.

Q: Do I need a GFCI breaker? A: Yes, GFCI (Ground Fault Circuit Interrupter) protection is required by the National Electrical Code (NEC) for all hot tub and spa installations.

Q: Does this pump replace the Aqua-Flo XP2e? A: Yes, this LX 48WUA2002C-II is a commonly used replacement for the Aqua-Flo XP2e 2.0 HP, 230V, 48 Frame, 2-Speed pump with 2-inch plumbing connections.
