2 ආරක්ෂිත තොරතුරු
වැදගත්: Installation of unvented hot water cylinders is subject to Building Control Regulations in the UK. It is mandatory to seek advice from and use a qualified installer for the installation of this product. Failure to comply with regulations can lead to serious hazards and may void your warranty.
UK building regulations require two forms of safety to be installed. This hot water cylinder is fitted with a temperature safety cut-off switch. Additionally, it is strongly recommended to install a safety expansion vessel and a pressure release valve within the connecting plumbing system to ensure full compliance and safe operation.

3. ස්ථාපනය (සැකසුම)
Installation must be carried out by a qualified professional in accordance with local building codes and regulations, particularly those pertaining to unvented hot water systems.
3.1. ස්ථාන තේරීම
- Choose a location that can support the weight of the cylinder when full (approximately 126 kg for the 100 Litre model).
- Ensure adequate space for maintenance and access to connections.
- The unit is designed for wall mounting.
- ශීත කිරීමේ උෂ්ණත්වයෙන් ඒකකය ආරක්ෂා කරන්න.
3.2. ඒකකය සවි කිරීම
- Securely attach the wall mounting brackets to a structurally sound wall using appropriate fasteners.
- Carefully lift and hang the cylinder onto the installed brackets. Ensure it is level and stable.
3.3. ජලනල සම්බන්ධතා
- Connect the cold water supply to the inlet (typically marked blue). The unit has 15mm water connections.
- Connect the hot water outlet (typically marked red) to your hot water distribution system.
- Install a safety expansion vessel and pressure release valve as required by regulations and manufacturer recommendations.
- සියලුම සම්බන්ධතා ජල ආරක්ෂිත බවට වග බලා ගන්න.
3.4. විදුලි සම්බන්ධතාවය

4. මෙහෙයුම
Once installed and filled with water, the TESY BiLight water heater is designed for straightforward operation.
4.1. මූලික ආරම්භය
- Ensure the cylinder is completely filled with water before switching on the power. Open a hot water tap to allow air to escape until water flows steadily.
- Switch on the electrical power supply to the unit.
- The light indicator on the unit will illuminate, indicating that the heating element is active and water is being heated.
4.2 උෂ්ණත්ව පාලනය
The unit features a temperature control dial, typically located at the bottom or side of the unit (refer to Figure 2). Rotate the dial to adjust the desired water temperature. Higher settings will provide hotter water, but also consume more energy. The unit has a built-in overheat protection system.
4.3. සාමාන්ය ක්රියාකාරිත්වය
The water heater will automatically maintain the set temperature. The light indicator will turn off once the desired temperature is reached and will illuminate again when the heating element reactivates to reheat the water.
5. නඩත්තු කිරීම
Regular maintenance ensures the longevity and efficient operation of your TESY BiLight water heater. All maintenance should be performed by a qualified technician.
- වාර්ෂික පරීක්ෂණය: It is recommended to have the unit inspected annually by a qualified professional. This includes checking the pressure relief valve, expansion vessel, and electrical connections.
- ඇනෝඩ දණ්ඩ පරීක්ෂාව: The glass-lined tank is protected by an anode rod. This rod should be inspected and replaced periodically (typically every 1-3 years, depending on water quality) to prevent corrosion.
- වැව ජලාපවහනය: If the unit will be out of use for an extended period or if there is a risk of freezing, the tank should be drained. Consult a professional for proper draining procedures.
- පිරිසිදු කිරීම: Keep the exterior of the unit clean with a damp රෙදි. උල්ෙල්ඛ පිරිසිදු කරන්නන් හෝ ද්රාවණ භාවිතා නොකරන්න.
