🛠️ Installation Requirements

Mounting:

Requirement	Specification
Mounting Position	Below water level (flooded suction) required
Base	Solid, level surface
Ventilation	Keep motor openings free from debris and obstructions
Access	Provide adequate space around pump for inspections and maintenance

Plumbing:

Connection	Size
Suction	2 inch MBT (center)
Discharge	2 inch MBT (side – rotatable to 4 positions)
Union Type	Compression fittings included (hand tighten only)

Installation Notes:

⚠️ Pump must be installed below water level (flooded suction) — the volute must be completely filled with water before starting

⚠️ Never run pump dry — causes seal damage and potential motor failure

⚠️ Ensure proper grounding and bonding per NEC requirements (No. 8 AWG solid copper)

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

⚠️ For compression fittings: hand tighten only — DO NOT use a wrench. DO NOT use thread seal tape (PTFE), Teflon compound, or any sealants on compression fittings

⚠️ For NPT threaded connections only: use Quick-Seal Teflon Thread Sealing Compound or sealants formulated specifically for plastics

🔧 Maintenance Guide

Routine Maintenance:

Task	Frequency	Notes
Check for leaks	Monthly	Inspect around seal plate and union connections
Inspect union fittings	Monthly	Hand tighten if loose — do not use tools
Keep motor vents clear	Quarterly	Remove any debris or obstructions from motor openings
Check mounting bolts	Quarterly	Tighten if vibration has loosened them
Inspect shaft seal	Annually	Replace at first sign of leakage
Check amperage draw	Annually	Should match rated 10.5A (high) / 3.2A (low)

Warning Signs — Replace Pump If:

• Unusual noise (grinding, screeching, or humming without starting)
• Water leaking from the shaft seal area
• Motor trips the circuit breaker repeatedly
• Noticeably reduced water flow despite clean filters
• Motor overheating and cycling on and off

Seal Replacement:

📍 Seal Type: PS-200 (Part No. 92500150) 📍 Always replace the complete seal assembly (both ceramic and carbon sides) every time the pump is disassembled

⚠️ Replace the seal at the first sign of any water leakage from the seal area.

Winterization:

To prevent freeze damage, disconnect all electrical power, drain the pump and plumbing lines thoroughly, and clean out any debris. Store the pump in a dry, well-ventilated area or cover it to protect from the elements.

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: This pump is rated at 1.0 HP continuous output (also referred to as 1.5 BHP or brake horsepower). The continuous output rating of 1.0 HP represents the actual sustained power delivered during operation.

Q: Will this fit my hot tub? A: This pump uses a 48Y frame (thru-bolt style) with 2-inch MBT connections on both suction and discharge. Measure the outside diameter of your existing pump’s threaded connections — if they measure approximately 3 inches, you have 2-inch ports. Also verify your existing pump has a 48-frame motor. If both match, this pump should be a compatible replacement.

Q: What voltage does this pump require? A: 115V / 60Hz. Always verify your existing pump’s voltage before ordering. This pump is not compatible with 230V circuits. Using the wrong voltage will damage the motor.

Q: Does this pump run on 115V or 230V? A: This specific model (06610006-2040) is a 115V pump. Gecko Alliance also manufactures 230V versions of the FMXP2 in higher horsepower ratings. Make sure to match the voltage of your current pump.

Q: Is this a single or dual speed pump? A: This is a dual-speed (2-speed) pump. High speed provides full power for jet operation, while low speed offers quiet, energy-efficient circulation for filtration cycles.

Q: What size are the ports? A: Both suction and discharge ports are 2-inch Male Buttress Thread (MBT). The outside diameter of the threaded connection measures approximately 3 inches. Suction is center-mounted; discharge is side-mounted and can be rotated to four positions.

Q: What warranty is included? A: This pump is covered by a 2-year full manufacturer warranty from Gecko Alliance. Years three through five are covered on a prorated basis. Pump seals carry a 30-day warranty. Contact Parts4Tubs for full warranty terms and details.

Q: How do I know if my pump needs replacing? A: Common signs include unusual noises (grinding, screeching, or humming), water leaking from the shaft seal, reduced jet pressure despite clean filters, the motor repeatedly tripping the circuit breaker, or the motor overheating and cycling on and off.

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 come with a power cord? A: No. This pump requires hardwire installation. A power cord is not included. All electrical connections must be performed by a licensed electrician in accordance with the NEC and local codes. The wiring diagram is located on the motor rating plate.

Q: Can I rotate the discharge direction? A: Yes. The wet end can be rotated to four positions, allowing you to orient the side discharge to match your plumbing layout.
