Using It on the Job

1. Isolate Power: Always begin by switching off power to the evaporative cooler at the main switchboard and applying a lockout tag to prevent accidental re-energisation.
2. Drain and Access: Completely drain the cooler's water reservoir and carefully disconnect the old pump. Take note of how the discharge line is connected.
3. Position New Pump: Place the new JRM50 pump securely in the reservoir. Ensure its power lead can reach the connection point without being stretched or pinched.
4. Connect Water Line: Reconnect the water discharge line from the pump to the cooler's water distribution system. Double-check for a snug, leak-free fit.
5. Wire Up: Reconnect the electrical wiring, ensuring all connections are tight, insulated, and match the original setup.
6. Test Run: Refill the cooler reservoir, remove the lockout tag, restore power, and test the pump for proper water circulation and any leaks before securing access panels.

Limitations & Safety Notes

• Not designed for use with potable (drinking) water systems.
• Ensure the pump is fully submerged in water before operating to prevent damage from dry running.
• All electrical connections should be made in accordance with Australian wiring regulations and by a licensed electrician if you are not a competent person.
• Only use for the specified voltage (240V) to avoid damage to the pump and electrical hazards.

Tradie Pro Tip

Before you fit a new pump, give the cooler's reservoir a good clean out. Sediment and scale build-up can shorten the life of even a brand new pump. A quick scrub can save you a call-back.

Pair With

Consider pairing this FASCO JRM50 pump with new evaporative cooler pads and a good quality descaling solution to ensure your entire system is running efficiently for the cooling season.
