2. Sikkerhedsoplysninger
Read and understand all safety warnings and instructions before operating the pump. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.
Generelle sikkerhedsforanstaltninger:
- Always disconnect power before servicing or moving the pump.
- Ensure the pump is properly grounded to prevent electric shock. Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections.
- Never operate the pump dry. Submersible pumps require water for cooling and lubrication.
- Do not use the power cord to lift or carry the pump. Use the designated handle.
- Keep hands, feet, and clothing clear of the pump's intake and discharge openings during operation.
- Do not pump flammable or explosive liquids, such as gasoline, fuel oil, or kerosene.
- Ensure the installation area is well-ventilated if the pump is used in an enclosed space.
- Protect the power cord from sharp objects, hot surfaces, oil, and chemicals.
3. Opsætning og installation
Korrekt installation er afgørende for pumpens ydeevne og levetid.
3.1 Udpakning og inspektion
- Tag forsigtigt pumpen ud af emballagen.
- Inspect the pump for any visible damage that may have occurred during shipping. Contact your supplier immediately if damage is found.
- Kontroller, at alle komponenterne på pakkelisten er til stede.
3.2 Placering
- Place the pump on a stable, level surface in the lowest part of the area to be dewatered.
- Ensure the pump's intake is clear of mud, sand, or large debris that could block it. A resin strainer is included to prevent larger particles from entering.
- Allow sufficient space around the pump for proper water flow and float switch movement.

3.3 Tilslutning af udløbsslange
- Connect a suitable discharge hose to the 3-inch angled discharge port.
- Secure the hose with a clamp to prevent leaks and disconnections during operation.
- Route the discharge hose away from the area to be dewatered, ensuring the water is directed to a safe and appropriate drainage location.
3.4 Elektrisk tilslutning
- Connect the pump to a grounded 115V power outlet.
- Always use a GFCI-protected outlet to minimize the risk of electric shock.
- Ensure the power cord is not stretched, pinched, or submerged in water. The anti-wicking cable entrance provides protection against water incursion due to cable damage.
4. Betjeningsvejledning
The Tsurumi HSZ3.75S pump is designed for automatic operation via its float switch.
4.1 Automatisk drift
- Once the pump is installed and connected to power, ensure the float switch is free to move.
- As the water level rises, the float switch will lift. When it reaches a certain height, the pump will automatically activate and begin pumping.
- The pump will continue to operate until the water level drops, causing the float switch to fall and deactivate the pump.
- Monitor the pump during its first few cycles to ensure proper function and float switch movement.
4.2 Vigtige driftsnoter
- Avoid operating the pump in extremely shallow water where the intake may become exposed, leading to dry running.
- The semi-vortex impeller and agitator are designed to suspend sand and small solids, preventing clogging and ensuring continuous flow.
- Regularly check the discharge flow to ensure the pump is operating efficiently.
