Grundfos Variable Speed Pump It has been carefully inspected and tested before shipment. It should give you long, efficient, troublefree service. For maximum performance and reliability, please follow the simple instructions in this manual.
1. Shipment Inspection Check the contents of this package. Care should be taken to ensure the pump is NOT dropped or mishandled; dropping will damage the pump. Grundfos Variable Speed Pump Package Includes: • • • • One Grundfos UP15-42 or UP26 Variable Speed pump with integral control. One 6’ line cord with 115V plug, pre-wired into control box. Two flange gaskets Installation and Operating Instructions. 2. General Features • All minimum and maximum settings are operating, not safety limits.
3. Operational Limits Control Signal Input Range Options: Voltage signal range: 0-10V(DC) or 2-10V(DC) Current signal range: 0-20mA or 4-20mA Grundfos Variable Speed pumps are designed to pump liquids compatible with their cast iron pump housing construction. They are recommended for use in closed hydronic systems. Grundfos Variable Speed pumps are for Indoor Use Only. Grundfos Variable Speed Pumps are intended for use with water, or a 50/50 mixture by weight of propylene glycol.
4. Pump Installation Warning: Consult piping manufactures for material selection before installing this pump. Absence of pumping fluid may damage some piping materials.
The pump must be installed with the motor shaft positioned horizontally. Under no circumstances should the pump be installed with the shaft vertical or where the shaft falls below the horizontal plane (Fig. 1). • Ensure that water does not enter the terminal box during the installation process. • DO NOT START THE PUMP UNTIL THE SYSTEM HAS BEEN FILLED AND CHECKED FOR LEAKS. • Do not use the pump to vent the system. • Never operate the pump dry.
Electrical Connections To The Control: CAUTION: The installer should confirm that no current/voltage is present at any of the wires. Note: Control signal wires must be run through and secured by the stain relief on the terminal board. Note: No speed control signal is necessary if speed is to be regulated using the manual % dial. Current Speed Control Signal Connections: Connect the current signal wires to terminals “Com(-)” and “Ret/I” (Fig 3.).
