Wiring Terminal Identification:

• C = Common (typically White wire)
• L = Low Speed (typically Black wire)
• H = High Speed (typically Red wire)
• Green = Ground

💡 Wiring Verification Tip: When powered on, the pump should start in low speed first. If the pump starts in high speed, power down immediately and reverse the black and red wires. Running in the wrong configuration can cause the motor to overheat and damage the hot tub system.

⚠️ IMPORTANT:

All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and local building codes. Hot tubs require GFCI (Ground Fault Circuit Interrupter) protection. A dedicated circuit is required — do not share with other appliances.

Bracket-Mounted Spas (NF Version): This baseless (NF) pump is designed for hot tubs that mount the pump using a bracket system rather than floor-mounted feet.

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: This pump is rated at 2.0 HP output power. You may also see it referenced as 3.08 HP input or 3.5 HP competitive/brake HP, which are alternative measurement standards. For accurate cross-brand comparison, use the amperage rating: 10.0A on high speed and 3.0A on low speed at 230V.

Q: Will this fit my hot tub? A: This pump has a 48-frame (thru-bolt) motor with 2″ MBT suction and discharge connections, and a baseless (NF) design for bracket mounting. Check that your existing pump matches: 48 frame, 2″ ports, bracket mount. If your current pump has feet, you need the standard version (48WUA2002C-II) with base.

Q: What voltage does this pump require? A: 230V / 60Hz. This pump must be wired to a dedicated 230V circuit. All electrical installation must be performed by a licensed electrician. Using 115V on this pump will result in damage.

Q: What is the difference between NF and standard versions? A: The NF (No Feet) version is baseless and designed for hot tubs that mount the pump using a bracket system (such as Sundance/Jacuzzi Theramax/Theraflo with bracket 6000-532). The standard version has feet/base attached for floor-mounted installations.

Q: Does a pump cord come with this pump? A: No, a pump cord is NOT included. You can reuse your existing 4-wire AMP cord or purchase a compatible replacement separately.

Q: What does it replace? A: This pump is a common replacement for Aqua-Flo XP2e (06120500-2040, 06125000-1040) and Waterway Executive 48-frame (3420820-10, 3421021-1U, 3420820-1A) pumps of the same specifications.

Q: Is this a single or dual speed pump? A: This is a 2-speed pump. High speed operates at 10.0A for jet massage. Low speed operates at 3.0A for filtration and circulation.

Q: What size are the ports? A: Both suction and discharge are 2″ MBT. The thread outer diameter measures approximately 3″ (3-1/16″) across. Two sets of 2″ unions are included.

Q: Can I rotate the discharge direction? A: Yes, the wet end can be rotated in 90-degree increments (12, 3, 6, or 9 o’clock positions) by loosening the four thru-bolts at the back of the motor.

Q: What warranty is included? A: 1-year manufacturer limited warranty from Guangdong Lingxiao Pump Industry Co., Ltd. The motor serial number label is required for all warranty claims.

Q: How do I know if my pump needs replacing? A: Signs include unusual noise (grinding or screeching), water leaking from the seal area, reduced jet pressure, the motor tripping the circuit breaker, or the motor overheating.

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: Are O-rings included with the unions? A: Unions are included, but O-rings are sold separately. Inspect your existing O-rings and replace if worn or damaged.
