REEFE® VSRM Series Pumps use the latest VVVF (Variable Voltage
and Variable Frequency) AC frequency speed regulation
technology. Combined with pressure sensing technology through
measuring of real-time system pressure, this allows the controller
to automatically adjust the motor speed and maintain a constant outlet pressure. They are very efficient, easy to
install and have user friendly interface controls for quick setup. No programming is required, simply set your desired
operating pressure and press RUN...let the controller save you money on your operating costs.

3. Installation and Operation instruction BEFORE IMPORTANT NOTICES: READ INSTALLATION 3.1 IMPORTANT MANDATORY INSTALLATION REQUIREMENTS: 1. IMPORTANT: a Check-Valve must be installed in the inlet pipe 2. IMPORTANT: Install using Barrel-Union connections for easy removal for repair or servicing. Install a Y-Strainer or Pre-Filter and also a Ball-Valve on the inlet piping. - Page 5 OFF, BEFORE the tank and pipes are dry. We recommend the RainPro Rain-Mains Valveset with a REEFE Pump Shut-Off Controller with Float Switch. Or use a “Piggy-Back” Float Switch, but ensure the installation is checked and approved by a licenced electrician.
- Page 6 6. IMPORTANT: Install using Barrel-Union connections for easy removal for repair or servicing. Install a Y-Strainer or Pre-Filter and also a Check Valve and Ball-Valve on the inlet piping.

MUST install an additional larger PRESSURE TANK between the pump and the first point of discharge, to avoid the continuous running. We suggest a REEFE Pressure Tank PT35H or larger. Warranty is voided by continuous running of the pump. - Page 9 This code displays if the pipe pressure reaches 99% of the maximum allowable pressure for the Transducer. Once the Over pressure pressure reduces to less than 96% of the max pressure, the VSD will revert to normal operation. When the input is three phase power, this code indicates that the Dropped Phase power supply has dropped from 3 Phase to 2 or 1 phase.
- Page 10 * Leakage of inlet (suction) pipe - Check the inlet pipe is not taking in air, check all joints. * Inlet Pipe has rise and fall (Dips). Fix suction pipe so it is both perfectly straight and level, OR slightly falls all the way to the pump.
