Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Hitachi WT-P200Y Automatic Shallow Well Pump. Please read this manual thoroughly before using the product and keep it for future reference.
The Hitachi WT-P200Y is an inverter-controlled automatic shallow well pump designed for reliable water supply. It features an easy-to-use control panel for convenient operation.
Safety Information
Always observe the following safety precautions to prevent injury or damage to the product.
- Ensure the power supply matches the pump's requirements (Single Phase 100V, 50/60Hz).
- Do not operate the pump without water, as this can cause damage.
- All electrical connections must be performed by a qualified electrician in accordance with local codes.
- Keep children and unauthorized personnel away from the pump during operation.
- Disconnect power before performing any maintenance or repairs.
- Protect the pump from freezing temperatures.
Setup and Installation
Proper installation is crucial for optimal performance and longevity of your pump.
- Unpacking: Carefully remove the pump from its packaging. Inspect for any shipping damage.
- Placement: Install the pump on a stable, level surface in a well-ventilated area, protected from direct sunlight, rain, and freezing. Ensure adequate space for maintenance.
- Piping Connections:
- Connect the suction pipe (25mm, Rc1) to the pump's suction inlet. Ensure an airtight seal to prevent air leaks.
- Connect the discharge pipe (25mm, Rc1) to the pump's discharge outlet.
- Use appropriate fittings and sealants to prevent leaks.
- Priming: Before initial operation, the pump must be primed.
- Remove the priming plug (if applicable) or fill the pump casing with water until full.
- Replace the plug securely.
- Electrical Connection: Connect the power cord to a grounded 100V, 50/60Hz power outlet. Ensure the circuit is protected by a suitable circuit breaker.

This helps in planning installation and understanding operational limits.
Operating Instructions
The WT-P200Y features an easy-to-use control panel for selecting operating modes.
- Initial Start-up:
- After ensuring proper installation and priming, plug in the pump.
- The pump will automatically start when water is demanded (e.g., opening a faucet) and stop when demand ceases.
- Selecting Operating Pressure Modes: The control panel allows selection of different pressure modes. Refer to the panel diagram for specific settings.
- Standard Mode: Provides balanced pressure for general household use.
- High Pressure Mode: For applications requiring stronger water pressure.
- Low Pressure Mode: For situations where reduced pressure is desired.
- Automatic Operation: The pump is designed for automatic operation. It will detect water demand and adjust its output accordingly, thanks to its inverter technology.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Monthly Checks:
- Inspect for any visible leaks around connections.
- Check for unusual noises or vibrations during operation.
- Annual Inspection:
- Clean any debris from the pump's exterior.
- Verify the condition of the power cord and plug.
- For internal component checks, it is recommended to contact a qualified service technician.
- Winterization (for cold climates):
- Drain all water from the pump and piping to prevent freezing damage.
- Store the pump in a warm, dry place if possible, or insulate it thoroughly.

Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power supply; tripped circuit breaker; motor overload. | Check power connection; reset circuit breaker; allow motor to cool down. |
| Pump runs but no water is delivered. | Pump not primed; air leak in suction line; low water level in well; clogged suction filter. | Re-prime the pump; check all suction connections for leaks; verify well water level; clean suction filter. |
| Low water pressure. | Partial clog in piping; incorrect pressure mode selected; worn impeller. | Check and clear piping; select higher pressure mode on control panel; contact service for impeller inspection. |
| Pump cycles frequently. | Small leak in plumbing system; pressure switch malfunction. | Inspect plumbing for leaks; contact service for pressure switch check. |
