1. Entwodiksyon ak pwodwi aview
This manual provides essential information for the safe and efficient operation of your WilTec 19L Domestic Autoclave Pump with Pressure Switch, Model 61544. Please read these instructions carefully before installation, operation, or maintenance. Keep this manual for future reference.
This comprehensive system, consisting of a diaphragm tank and a powerful pressure switch pump, is designed for supplying clear water to both your home and garden. It is ideal for domestic water supply using rainwater, wastewater, or groundwater, reducing reliance on tap water for showering, laundry, and toilet use. In the garden, it supports automatic irrigation systems. The system can also be integrated into existing water networks to boost pressure.
It features a 1200W motor, a delivery head of 30m at 3 bar operating pressure, and a maximum pump pressure of 4.8 bar, delivering up to 3400 liters of clear water per hour. The 19-liter pressure tank is made of shock-resistant iron for stability and durability. A convenient handle facilitates easy transport, making it suitable for mobile use. An integrated manometer allows precise monitoring of operating pressure. The pressure switch activates the pump when water pressure drops due to water draw-off and automatically deactivates it once the tank is refilled. Maximum cut-in pressure is 1.5 bar, and maximum cut-out pressure is 3 bar. A larger tank capacity results in less frequent pump activation, leading to reduced energy consumption and electricity costs.

2. Enstriksyon Sekirite
AVÈTISMAN: Failure to follow these safety instructions can result in electric shock, fire, serious injury, or death.
- Always disconnect the pump from the power supply before performing any installation, maintenance, or cleaning tasks.
- Ensure the electrical supply matches the specifications on the pump's rating plate.
- The pump must be connected to a properly grounded outlet with a residual current device (RCD) for personal protection.
- Do not operate the pump with damaged cables or plugs. Have them replaced by a qualified electrician.
- Pwoteje ponp lan kont jèl. Vide dlo ponp lan nèt si gen risk pou l konjele.
- This pump is designed for pumping clear water only. Do not use it for flammable, corrosive, explosive, or abrasive liquids.
- Never run the pump dry. Ensure the pump is always primed with water before starting.
- Kenbe timoun ak moun ki pa otorize lwen ponp ki ap fonksyone a.
- Ensure adequate ventilation around the pump during operation.
- Do not lift or carry the pump by its electrical cable.
3. Enstalasyon ak Enstalasyon
3.1 Debalaj ak enspeksyon
- Retire ponp lan nan anbalaj li avèk prekosyon.
- Inspect the pump for any signs of damage that may have occurred during transit. Do not operate a damaged pump.
- Asire w ke tout eleman yo prezan.
3.2 Plasman
- Place the pump on a firm, level, and stable surface to prevent vibration and movement.
- Position the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and frost.
- Ensure sufficient space around the pump for ventilation and maintenance access.
3.3 Koneksyon elektrik
- Connect the pump to a standard 230V, 50Hz electrical outlet.
- Always use a grounded outlet protected by a residual current device (RCD) with a tripping current of no more than 30mA.
- Ensure the power cable is not stretched, pinched, or exposed to sharp edges.
3.4 Suction Line Connection
- Connect a non-collapsible, airtight suction hose to the pump's suction inlet. Use thread sealant tape for a secure, leak-free connection.
- The suction hose should be as short and straight as possible to minimize friction loss.
- Install a foot valve with a filter at the end of the suction hose in the water source to prevent debris from entering the pump and to maintain prime.
- Ensure the foot valve is always submerged in water.
3.5 Koneksyon Liy Presyon
- Connect the pressure hose to the pump's pressure outlet.
- Asire w ke tout koneksyon yo sere epi yo pa koule.
3.6 Priming ponp lan
- Before initial startup, the pump housing must be completely filled with water through the priming port (usually located on top of the pump).
- Open any valves in the pressure line to allow air to escape during priming.
- Once filled, close the priming port securely.

4. Operasyon Enstriksyon
4.1 Premye demaraj
- Ensure the pump is properly installed and primed as described in Section 3.
- Plug the pump into the electrical outlet. The pump will start automatically if the pressure in the tank is below the cut-in pressure.
- Monitor the manometer to observe the pressure build-up.
- Allow the pump to run until it reaches the cut-out pressure and switches off automatically.
4.2 Operasyon otomatik
- The integrated pressure switch controls the pump's operation. When water is drawn from the system (e.g., opening a tap), the pressure drops.
- Once the pressure falls below the set cut-in pressure (approx. 1.5 bar), the pump automatically starts to replenish the tank and supply water.
- When water draw-off stops and the system pressure reaches the set cut-out pressure (approx. 3 bar), the pump automatically switches off.
- This automatic start/stop function ensures efficient water supply and reduces energy consumption.
4.3 Siveyans
- Regularly check the manometer to ensure the system is operating within expected pressure ranges.
- Koute pou bri oswa vibrasyon dwòl, ki ka endike yon pwoblèm.
4.4 Fèmen
- For temporary shutdown, simply unplug the pump from the power outlet.
- For extended periods of non-use or winterization, follow the maintenance instructions in Section 5.
5. Antretyen
Antretyen regilye asire lonjevite ak pèfòmans optimal ponp ou a.
5.1 Chèk jeneral
- Periodically check all connections for leaks. Tighten as necessary.
- Enspekte kab pouvwa a ak ploge pou nenpòt domaj.
- Ensure the pump's ventilation openings are clear of debris.
5.2 Suction Filter Cleaning
- If a foot valve with a filter is used, regularly check and clean the filter to prevent clogging and maintain efficient suction.
- A clogged filter can lead to reduced pump performance or dry running.
5.3 Diaphragm Tank Pressure Check
- The air pressure in the diaphragm tank should be checked periodically (e.g., every 6-12 months) when the pump is depressurized and empty of water.
- The pre-charge pressure should typically be around 1.5 bar (check product specifications for exact value). Adjust with a standard air pump if necessary.
- Incorrect tank pressure can lead to frequent pump cycling.
5.4 Winterization
- If the pump is stored or used in an area where temperatures may drop below freezing, it must be completely drained to prevent damage from ice expansion.
- Dekonekte ekipman pou pouvwa a.
- Open the drain plug (if available) and disconnect the suction and pressure lines to allow all water to escape.
- Sere ponp lan nan yon kote ki sèk epi ki pa gen jèl.
