2. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your Red Lion jet pump. Always ensure the pump is disconnected from the power source before beginning any installation or maintenance procedures. Refer to local electrical and plumbing codes for compliance.

2.1. Installation Location

Install the pump in a dry, ventilated location that is protected from direct sunlight and freezing temperatures. Bolt the unit down to an even, solid surface to prevent movement. Install the pump as close as possible to the water source to minimize suction lift.

2.2. Electrical Connections and Voltage Change

The RJS-50-PREM pump motor is factory-set for 230 Volts. If your power source is 115 Volts, you must change the voltage setting on the pump motor. Ensure the pump's voltage setting matches your power source voltage to prevent damage and ensure proper operation.

2.3. Plumbing Connections

The pump's suction inlet is 1-1/4" FNPT and the discharge is 1" FNPT. It is recommended to use pipe sizes that match these fittings for optimal performance. Ensure all plumbing connections are air-tight to prevent leaks and maintain pump efficiency.

3. Operating Instructions

Before starting the pump for the first time or after any maintenance that involves draining the system, it must be properly primed by filling it with water. Ensure all valves are in the correct position before activating the pump.

Once primed and all connections are secure, turn on the power supply to the pump. The pump should start and build pressure. The factory pre-set pressure switch will automatically turn the pump off when the desired pressure is reached and turn it back on when pressure drops due to water demand.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Red Lion jet pump. Always disconnect the electrical power to the pump before performing any maintenance.
