Setup and Installation
Installation of this instant electric water heater requires professional expertise. It is strongly recommended that installation be carried out by a qualified electrician and plumber to ensure safety and compliance with local regulations.
Pre-Installation Checklist:
- Verify that the electrical supply voltage and current capacity are compatible with the heater's requirements.
- Ensure adequate water pressure is available at the installation site.
- Select a suitable wall-mounting location, away from direct splashes and within reach of power and water lines.
- Confirm all necessary mounting hardware and plumbing fittings are available.
Installation Steps (Professional Installation Recommended):
- Mounting: Securely mount the water heater to a sturdy wall using appropriate fasteners. The unit is designed for wall mounting.
- Water Connections: Connect the water inlet and outlet pipes. Ensure all connections are watertight and sealed properly to prevent leaks.
- Electrical Connections: Connect the electrical wiring to a dedicated circuit breaker, ensuring proper grounding. Follow the wiring diagram provided in the full installation guide (not included in this manual).
- Water Flow Check: Before powering on, open the water supply to the heater and allow water to flow through the showerhead to purge any air from the system. Check for leaks.
- Power On: Once water flow is established and checked, switch on the electrical power supply to the unit.
Operating Instructions
The Toshiba DSK33ES5SB is designed for user-friendly operation.
- Power On: Ensure the main power switch for the water heater is in the "ON" position.
- Water Flow Activation: Turn on the water tap or shower mixer connected to the water heater. The built-in auto flow sensor will detect water flow and automatically activate the heating element.
- Temperature Adjustment: Use the stepless electronic temperature control knob or buttons on the unit to adjust the desired water temperature. Rotate clockwise for hotter water, counter-clockwise for cooler water. The selected temperature may be visible on a display, if equipped.
- Showerhead Settings: Utilize the 5-spray pattern showerhead to select your preferred water spray type (e.g., massage, mist, full spray).
- Power Off: To turn off the heater, simply close the water tap or shower mixer. The auto flow sensor will deactivate the heating element. For extended periods of non-use, it is recommended to switch off the main power supply to the unit.
Note: Water temperature can fluctuate depending on the incoming water volume and temperature. Adjust the control as needed for consistent comfort.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater.
- Cleaning the Exterior: Wipe the exterior casing with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish. Ensure the unit is powered off before cleaning.
- Showerhead Cleaning: Periodically clean the showerhead nozzles to remove mineral deposits and ensure optimal spray patterns. Most showerheads have rubber nozzles that can be rubbed to dislodge deposits, or they can be soaked in a descaling solution.
- Inlet Filter Cleaning: The water inlet may have a filter screen to prevent debris from entering the unit. Refer to the full product manual for instructions on how to safely access and clean this filter, if applicable. This typically requires turning off the water supply and disconnecting the inlet hose.
- Professional Inspection: It is recommended to have a qualified technician inspect the unit annually, especially for electrical and plumbing connections, to ensure continued safe and efficient operation.
