6. Operating Instructions
The Truper PRE-1/6 pump is designed for user-friendly operation.
- Power On: Once installed and connected to the power supply, ensure the pump's switch is in the 'AUTO' position for automatic operation.
- Automatic Operation: The integrated flow sensor will detect water flow when a faucet or appliance is opened, automatically starting the pump to boost pressure. When water flow stops, the pump will turn off.
- Manual Mode: The pump may have a 'MANUAL' setting for continuous operation, typically used for priming or specific tasks. Refer to the switch on the unit.
- Off Position: Use the 'OFF' position to completely shut down the pump, for example, during maintenance or extended periods of non-use.
- Recommended Use: This pump is ideal for boosting pressure for a single service point.
- Duty Cycle: To ensure optimal performance and longevity, adhere to the recommended duty cycle of 50 minutes of continuous operation followed by 20 minutes of rest. The maximum daily operation should not exceed 6 hours.
