Figure 2: Installation diagram and dimensions for the Kospel EPO2-3 AMICUS.
3.1. Mounting
- Choose a suitable location, preferably directly under the sink, ensuring easy access for maintenance.
- Mount the heater vertically using appropriate fasteners, ensuring it is level and securely fixed to a solid surface.
- The unit can be mounted in any position, above or below the tap, with connections from the top or bottom.
3.2. Water Connection
- Connect the cold water supply to the blue marked inlet (GZ 3/8").
- Connect the hot water outlet to the red marked outlet (GZ 3/8").
- Ensure all connections are watertight. The distance between the branches is approximately 80 mm.
- The minimum water pressure required is 1.2 bar, with a maximum of 6.0 bar.
- Before connecting to the heater, flush the water pipes to remove any debris.
3.3. Electrical Connection
- The heater requires a 230V power supply.
- Connect the heater to a dedicated electrical circuit with appropriate overcurrent protection (e.g., a circuit breaker).
- The minimum section of cables required is 3 x 1.5 mm².
- Ensure proper grounding.
- All electrical work must comply with local electrical codes.
4. Operation
4.1. First Use
- Before switching on the power, open the hot water tap to allow water to flow through the heater and expel any air from the system.
- Once water flows steadily from the tap, close the tap.
- Switch on the electrical power to the heater. The indicator light on the front of the unit will illuminate when the heater is active.
4.2. Daily Use
- To obtain hot water, simply open the hot water tap. The heater will automatically activate when water flows through it.
- The water temperature is regulated by the flow rate. A lower flow rate will result in hotter water, while a higher flow rate will result in cooler water.
- The EPO2-3 AMICUS model provides approximately 1.7 liters per minute of hot water at a 30°C temperature rise.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater.
- Cleaning: Periodically wipe the exterior of the heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Descaling: In areas with hard water, mineral deposits can accumulate inside the heater. It is recommended to have the unit descaled by a qualified technician annually or as needed.
- Water Filter: If your water supply has a filter, check and clean it regularly according to the filter manufacturer's instructions.
- Inspection: Periodically check for any signs of leaks, corrosion, or damage to the power cord and water connections. If any issues are found, disconnect power and contact a qualified technician.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Heater not activating | No power supply Insufficient water flow Air in the system | Check circuit breaker/fuse Ensure water pressure is adequate (1.2-6.0 bar) Open hot water tap to purge air |
| Water not hot enough | High water flow rate Low incoming water temperature Mineral buildup | Reduce water flow at the tap This is an instantaneous heater, temperature rise is fixed Contact a qualified technician for descaling |
| Water leakage | Loose connections Damaged seals/pipes | Tighten water connections Contact a qualified technician for repair |
| Unusual noise | Air in the system Mineral buildup | Purge air by opening hot water tap Contact a qualified technician for descaling |
If the problem persists after attempting these solutions, please contact a qualified service technician.
