1. Úvod
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your DAB JET 82 M self-priming centrifugal pump. Please read these instructions carefully before installation and use, and keep them for future reference.
The DAB JET 82 M is a self-priming centrifugal pump designed for domestic water supply systems, small-scale agriculture, and gardening. Its self-priming capability is particularly effective even in the presence of air bubbles. The pump is suitable for pumping clean, non-viscous, non-aggressive, non-crystallized, and chemically neutral liquids, free from solid particles or abrasive substances.

2. Bezpečnostní pokyny
VAROVÁNÍ: Nedodržení těchto bezpečnostních pokynů může vést k úrazu elektrickým proudem, požáru, vážnému zranění nebo smrti.
- Elektrická bezpečnost: Ensure the power supply matches the pump's specifications (1 x 220-240 V, 50 Hz). All electrical connections must be performed by a qualified electrician and comply with local regulations. Disconnect power before any maintenance or installation.
- Instalační prostředí: Install the pump in a dry, well-ventilated area, protected from direct sunlight and frost. The maximum ambient temperature should not exceed +40 °C.
- Teplota kapaliny: The liquid temperature range is 0 °C to +35 °C for domestic use (EN60335-2-41) and 0 °C to +40 °C for other uses. Do not pump liquids outside this range.
- Tlak: The maximum operating pressure is 6 bar (600 kPa). Do not exceed this pressure.
- Ochrana: The pump has an IP 44 protection rating (IP 55 at the terminal board) and Class F insulation.
- Děti a neoprávněné osoby: Během provozu držte děti a nepovolané osoby v dostatečné vzdálenosti od čerpadla.
- Údržba: Only qualified personnel should perform maintenance. Use only original spare parts.
3. Nastavení a instalace
3.1 Vybalení
Carefully remove the pump from its packaging. Inspect for any signs of damage during transit. Report any damage to the supplier immediately.
3.2 Montáž
Mount the pump on a stable, level surface to minimize vibration. Secure it using appropriate fasteners. Ensure there is adequate space around the pump for ventilation and maintenance.
3.3 Hydraulické spoje
Connect the suction and discharge pipes to the pump. Ensure all connections are watertight to prevent air leaks, which can affect the pump's self-priming ability. Use appropriate fittings and sealants.
Refer to the diagram below for connection points and dimensions.

3.4 Elektrické připojení
Connect the pump to a suitable power supply (1 x 220-240 V, 50 Hz) via a dedicated circuit breaker or fuse. Ensure proper grounding. The pump has integrated thermo-amperometric protection and a permanently inserted capacitor.
4. Provoz
4.1 Naplnění čerpadla
Before the first start-up, the pump body must be filled with the liquid to be pumped through the dedicated filling plug. This is crucial for the self-priming function. Once filled, replace the plug securely.
4.2 Spuštění čerpadla
Once primed and all connections are secure, switch on the power supply. The pump should start operating. Monitor for any unusual noises or vibrations.
4.3 Výkonnostní charakteristiky
The pump operates within a flow rate of 0.4 to 3.6 m³/h with heads up to 47 meters. The performance curve below illustrates the relationship between flow rate (Q) and head (H) for the JET 82 M model compared to other models.

4.4 Vypnutí čerpadla
To stop the pump, switch off the power supply. For prolonged periods of inactivity, especially in cold climates, drain the pump to prevent frost damage.
5. Údržba
Regular maintenance ensures the longevity and optimal performance of your DAB JET 82 M pump. Always disconnect the power supply before performing any maintenance.
- Pravidelná kontrola: Periodically check for leaks, unusual noises, or vibrations. Ensure all connections are tight.
- Čištění: Keep the pump exterior clean and free from debris to ensure proper motor cooling.
- Ochrana proti mrazu: In areas prone to freezing temperatures, drain the pump completely and store it in a frost-free environment when not in use.
- Mechanická ucpávka: The mechanical seal is made of carbon/ceramic. If leaks occur from the seal area, it may need replacement by a qualified technician.
6. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Čerpadlo se nespustí | Žádné napájení Ochrana motoru proti přetížení se aktivovala Seized impeller | Zkontrolujte připojení napájení a jistič Allow motor to cool, check for blockages Kontaktujte kvalifikovaného technika |
| Čerpadlo běží, ale voda se nedodává | Čerpadlo není naplněno Únik vzduchu v sacím potrubí Příliš vysoká sací výška Foot valve blocked or faulty | Prime the pump (fill with water) Zkontrolujte těsnost všech sacích spojů Reduce suction lift or reposition pump Inspect and clean/replace foot valve |
| Snížený průtok nebo tlak | Částečné zablokování sání/výtlaku Vzduch v systému Worn impeller/diffuser | Inspect and clear pipes Check for air leaks, re-prime if necessary Contact qualified technician for inspection/replacement |
