- Do not operate the pump if it is damaged or malfunctioning.
- Keep the work area well-ventilated.
- Disconnect power before performing any maintenance or cleaning.
- Avoid prolonged dry running of the pump.
4. Setup and Installation
Follow these steps to set up your GROZ Electric Drum Pump:
- Assemble Suction Tube: Extend the telescopic suction tube to the desired length to reach near the bottom of your drum. Secure it firmly.
- Attach Hose and Nozzle: Connect the flexible corrugated hose to the pump outlet. Attach the manual dispensing nozzle to the other end of the hose. Ensure all connections are tight to prevent leaks.
- Mount on Drum: Insert the pump's suction tube into the drum opening. The integrated 2" bung adaptor should fit directly onto standard 55-gallon drum threads. Tighten the bung adaptor to secure the pump to the drum. If your drum has buttress threads, use the provided thread converter.
- Connect Power: Connect the red crocodile clip to the positive (+) terminal of a 12V DC power source (e.g., car battery) and the black clip to the negative (-) terminal. Ensure a secure connection.
