1. Introduksjon
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your ELDOM Favourite WH05039L horizontal storage water heater. Please read these instructions carefully before installation and use, and retain them for future reference. This water heater is designed for horizontal installation, making it suitable for spaces where a vertical boiler may not fit.
Key features include thick, dense CFC-free insulation for minimal energy loss, a high-temperature resistant boiler lining, antifreeze protection, and dual magnesium anode systems to protect against rust. The unit is CE certified, ensuring compliance with European safety standards, and includes a 3-in-1 metallic combined safety valve.

2. Sikkerhetsinformasjon
ADVARSEL: Unnlatelse av å følge disse sikkerhetsinstruksjonene kan føre til elektrisk støt, brann, skade på eiendom eller personskade.
- Installasjon og vedlikehold må utføres av kvalifisert personell i samsvar med lokale forskrifter og denne håndboken.
- Ensure the electrical supply matches the specifications of the water heater (230V, 2kW).
- Koble alltid fra strømmen før du utfører vedlikehold eller service.
- Ikke bruk varmtvannsberederen hvis den er skadet eller ikke fungerer som den skal.
- Varmtvannsberederen må være skikkelig jordet.
- Do not block the safety valve. Regular inspection of the safety valve is recommended.
- Hold brennbare materialer unna varmtvannsberederen.
- Dette apparatet er ikke beregnet for bruk av personer (inkludert barn) med reduserte fysiske, sensoriske eller mentale evner, eller mangel på erfaring og kunnskap, med mindre de har fått tilsyn eller instruksjoner om bruk av apparatet av en person som er ansvarlig for deres sikkerhet.
- Barn bør overvåkes for å sikre at de ikke leker med apparatet.
3. Oppsett og installasjon
The ELDOM WH05039L is designed for horizontal wall mounting. Ensure the mounting surface is structurally sound and capable of supporting the water heater's weight when full (approx. 19 kg empty + 50 kg water = 69 kg).
3.1 Montering
Mount the water heater horizontally using appropriate wall anchors and brackets (not always included, check packaging). Refer to the dimension diagram for precise measurements and mounting points.

Figure 2: Technical diagrams showing dimensions, internal components, and connection points. Note the left-side connections.
The diagram illustrates the external dimensions (A, B, C, D, E, F, G, M) and internal structure. Pay attention to the mounting points (labeled 4 in the top-left diagram) and the position of the heating element (5 in the bottom-left diagram).
3.2 VVS-tilkoblinger
The water heater features connections on the venstre side. Ensure proper plumbing for hot and cold water lines.
- Hot water outlet (1): Connect to the hot water supply system.
- Cold water inlet - Drain (2): Connect to the cold water supply. This connection also serves as the drain point.
- Sikkerhetsventil: Install the included 3-in-1 metallic combined safety valve on the cold water inlet. This valve is crucial for pressure relief and preventing backflow. Ensure the discharge pipe from the safety valve is routed to an open drain.
All connections are G1/2M. Use appropriate sealing materials to prevent leaks.
3.3 Elektrisk tilkobling
Connect the water heater to a dedicated electrical circuit. The unit requires 230 Volts (AC) and has a power rating of 2 kW (10 Amperes). Ensure the circuit is protected by a suitable circuit breaker and that proper grounding is established.
- The electrical connection point is typically located under the control panel cover (4 in the top-right diagram).
- Ensure all wiring is secure and insulated.
- The on/off switch is illuminated and waterproof.
4. Drift
Once installed and filled with water, the ELDOM WH05039L is ready for operation.
4.1 Fylle varmtvannsberederen
- Before switching on the power, ensure the water heater is completely filled with water.
- Open a hot water tap in your home to allow air to escape from the tank.
- Open the cold water inlet valve to fill the tank.
- Once water flows steadily from the hot water tap, the tank is full. Close the hot water tap.
4.2 Slå på og innstille temperatur
- Switch on the main power supply to the water heater using the illuminated on/off switch.
- Adjust the desired water temperature using the external mechanical thermostat. The temperature indicator (3 in the top-right diagram) will show the current water temperature.
- The recommended thermostat setting for optimal energy efficiency and safety is typically around 60°C.
4.3 Antifreeze Protection
The water heater is equipped with antifreeze protection. In cold environments, this feature helps prevent water inside the tank from freezing, protecting the unit from damage. However, for prolonged periods of non-use in freezing conditions, it is advisable to drain the water heater completely.
5. Vedlikehold
Regular maintenance ensures the longevity and efficient operation of your ELDOM water heater.
5.1 Magnesium Anode Inspection and Replacement
The water heater features two magnesium anode systems to protect the tank from corrosion and rust. These anodes are sacrificial and deplete over time. It is recommended to have them inspected annually by a qualified technician and replaced as necessary, typically every 1-3 years depending on water quality.
5.2 Tømme varmtvannsberederen
Draining may be required for maintenance, prolonged periods of non-use, or to prevent freezing. To drain:
- Slå av strømforsyningen til varmtvannsberederen.
- Steng kaldtvannsinntaksventilen.
- Open a hot water tap in your home to relieve pressure and allow air into the tank.
- Connect a hose to the cold water inlet/drain connection (2) and route it to a suitable drain.
- Open the drain valve (if separate, or use the cold water inlet connection) to allow water to flow out.
- Når vannet er tømt, lukk avløpsventilen og varmtvannskranen.
5.3 Safety Valve Check
Periodically check the safety valve by lifting the lever to ensure it operates freely and discharges water. This helps prevent mineral buildup. If the valve does not discharge water or leaks continuously, it may need replacement.
5.4 Rengjøring
Rengjør utsiden av varmtvannsberederen med en myk, tørr klut.amp klut. Ikke bruk skurende rengjøringsmidler eller løsemidler.
6. Feilsøking
This section provides solutions to common issues. For problems not listed here, or if you are unsure, contact qualified service personnel.
| Problem | Mulig årsak | Løsning |
|---|---|---|
| Ikke varmt vann | No power, thermostat set too low, heating element failure. | Check power supply and circuit breaker. Adjust thermostat. If element failure is suspected, contact service. |
| Vannet er ikke varmt nok | Thermostat set too low, excessive hot water usage, sediment buildup. | Increase thermostat setting. Allow recovery time between uses. Consider draining and flushing the tank. |
| Vannlekkasjer | Loose connections, faulty safety valve, tank corrosion. | Tighten connections. Inspect and replace safety valve if necessary. Tank corrosion usually requires replacement. |
| Uvanlige lyder (f.eks. popping, rumling) | Sedimentoppbygging i tanken. | Tøm og spyl tanken for å fjerne sediment. |
