1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Foset REGEL-4A Electric Shower Head. Please read these instructions thoroughly before installation and use, and retain them for future reference. The Foset REGEL-4A is designed to provide instant hot water with four adjustable temperature levels, ensuring a comfortable showering experience.
2. Safety Information
WARNING: Risk of Electric Shock. Installation must be performed by a qualified electrician in accordance with all local electrical codes and regulations. Failure to follow these instructions can result in electric shock, fire, or property damage.
- Ensure the electrical installation includes an independent circuit directly from the main load center.
- A circuit breaker with a minimum capacity of 50 A (for 127 V systems) is required.
- Use appropriate wire gauge: 10 AWG for distances less than 30 meters, and 8 AWG for distances greater than 30 meters from the main electrical panel.
- Do not use extension cords, adapters, or multiple outlets with this appliance.
- Ensure proper grounding (Green wire) is connected.
- Never operate the shower head if it is damaged or malfunctioning.
- Before any maintenance or cleaning, always disconnect the power supply to the shower head at the circuit breaker.
3. Package Contents

5. Installation
5.1 Pre-installation Requirements
- Water Pressure: The water tank (tinaco) height must be between 1 and 10 meters above the shower head for optimal water pressure. If the height is greater than 5 meters, a reducer may be required at the base of the water tank.
- Electrical Supply: As detailed in Section 2, ensure a dedicated 127 V circuit with a 50 A breaker and appropriate wire gauge (10 AWG for <30m, 8 AWG for >30m).
5.2 Physical Installation
- Turn off the main water supply to the installation area.
- Mount the shower arm securely to the wall, ensuring it is level and properly sealed to prevent leaks.
- Attach the Foset REGEL-4A Electric Shower Head to the shower arm. Hand-tighten first, then use a wrench if necessary, being careful not to overtighten.
- Connect the 1.5-meter PVC hose to the shower head and the sprayer. Mount the sprayer support to a convenient location on the wall.
- Turn on the main water supply and check for any leaks. Address any leaks before proceeding.
5.3 Electrical Connection
IMPORTANT: Ensure power is OFF at the main circuit breaker before making any electrical connections.

Figure 3: Electrical Installation Diagram. This diagram shows the required independent electrical connection, wire color coding (Blue: Line, White: Neutral, Green: Ground), recommended wire gauges based on distance, and the necessary water tank height for proper operation.
- Identify the electrical wires from the shower head: Blue (Line), White (Neutral), and Green (Ground).
- Connect these wires to the corresponding wires of your dedicated electrical circuit. Ensure secure connections using appropriate electrical connectors.
- Verify that the ground wire (Green) is properly connected to the electrical system's ground.
- Once all connections are secure and insulated, close the electrical junction box.
- Double-check all connections before restoring power.
6. Operation
- After installation and before turning on the electrical power, allow water to flow through the shower head for at least 30 seconds to ensure the heating element is fully submerged. This prevents damage to the heating element.
- Restore power to the shower head at the circuit breaker.
- The Foset REGEL-4A features a selector for four temperature levels:
- Off: No heating.
- Tibia: Warm water.
- Caliente: Hot water.
- Muy Caliente: Very hot water.
- Rotate the selector on the shower head to your desired temperature setting.
- Adjust the water flow from your faucet to fine-tune the temperature. Lower flow generally results in hotter water, while higher flow results in cooler water for a given setting.
7. Maintenance
- Cleaning: Regularly clean the exterior of the shower head with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the polypropylene body.
- Nozzle Cleaning: Periodically check the shower nozzles for mineral deposits or blockages. Gently clean them with a soft brush or by hand to maintain optimal water flow.
- Descaling: In areas with hard water, mineral buildup can affect performance. If water flow is reduced or heating efficiency decreases, the internal components may require descaling. Consult a qualified technician for internal descaling procedures.
- Winterization (if applicable): If the shower head is in an unheated area subject to freezing temperatures, ensure the water supply is drained to prevent damage from freezing.
8. Troubleshooting
| Problem | Possible Cause | Solution |
