1. Rough-in & Toilet Positioning

Rough-in Distance (Critical)

• Standard rough-in: 12 inches (305 mm) from finished wall to flange center
• Always verify before installation

⚠ Incorrect rough-in size may prevent proper installation

---

Side Clearance

• Minimum: 15 inches (38 cm) from centerline to wall/obstacle

---

Front Clearance

• Recommended: ≥ 30 inches (76 cm)

⚠ Provides better comfort and meets modern bathroom design standards

---

Floor & Leveling

• Floor must be solid, level, and finished
• Ensure toilet is level (front-back & side-side)
• Prevents:
  • Wobbling
  • Seal failure
  • Noise

✅ Correct Installation:

---

⚠️ Important Note

• The building’s plumbing system already includes internal trap protection
• No additional trap is required or allowed

⚠  Adding extra bends or traps may cause:

• Weak flushing
• Drain blockage
• Water backup

---

Flange Installation

• Flange must be:
  • Flush with finished floor or slightly above
  • Firmly secured
• Use:
  • Wax ring or high-quality rubber seal

---

3. Water Supply (Angle Valve Position)

Recommended Position

Height

• Approx. 6 inches (15 cm) above floor

---

Distance from Centerline

• Ideal: 6–10 inches (15–25 cm)

---

Installation Notes

• Use Teflon tape to prevent leaks
• Test for leakage before final installation

---

Water Pressure Recommendation

EPLO smart toilets are designed for a wide range of water pressure conditions:

• Models with built-in tank & booster pump perform well even in low water pressure environments

---

4. Electrical Requirements

Outlet Type

• Must use GFCI outlet (Ground Fault Circuit Interrupter)

---

Recommended Position

• Same side as angle valve
• Avoid crossing cables behind toilet

---

Height

• Approx. 12 inches (30 cm) above floor

---

Distance from Toilet

• Ideal: 12–24 inches (30–60 cm)

---

Power Supply Recommendation

Flush Test

• Flush multiple times
• Confirm:
  • Strong flushing
  • No backflow

---

Function Test

• Test all smart features:
  • Bidet wash
  • Seat heating
  • Dryer
