SAFETY WARNING Notes Read This Booklet This booklet is designed to help a certified installer install, begin operation of and troubleshoot the Grundfos VersaFlo UPS pumps. It should be left with the owner of the pump for future reference and information regarding its operation. Should the owner experience any problems with the pump, a certified professional should be contacted.

Installation Procedures Replacing Components WARNING: Never make any connections in the pump terminal box unless the electrical supply has been switched off. AVERTISSEMENT: Ne jamais établir de connexions dans la boîte de jonction de la pompe à moins que l’alimentation électrique n’ait été coupée. 1. Electrical Preparation Terminal Box Position At the bottom of the stator, closest to the pump housing, there are two drain holes to allow condensed water to escape. The drain holes must point downwards.

Winding Resistance (line to line) Installation Procedures VersaFlo UPS 3x460V & 575V Terminal Box: All VersaFlo UPS single head pumps with 3 phase x 460V & 575V terminal boxes (Fig.8) come with a special two speed terminal box. The speed is changed by the orientation of the jumpers as shown on page 9. All are equipped with an internal thermal overload switch (terminals P1 & P2) to be connected to external contactor. To check the winding resistance of the motor windings, a megohmmeter is required. 1.

Troubleshooting Starting the Pump 1. Vent the Piping System Insulation Resistance (lead-to-ground) After the pump has been installed and the electrical connections made, the piping system must be vented. Never operate the pump dry -- the system must first be filled with liquid and vented. Do not vent the piping system through the pump. Instead, follow these steps: To check the insulation resistance (lead-to-ground) of the motor and leads, a megohmmeter is required. a.

Troubleshooting Starting the Pump 3a. Speed Selection Preliminary Checks Supply Voltage (three speed, all models except 3 x 460V & 575V) To check the voltage being supplied to the motor, use a voltmeter. Be careful, since power is still being supplied to the pump. Do not touch the voltmeter leads together while they are in contact with the power lines. The speed switch in the terminal box can be turned to three positions. The speed in the three positions appears in the table below (also see Fig.13).

Troubleshooting Starting the Pump Change the pump performance as follows: (continued) 4. Fit the terminal box cover back onto the terminal box and tighten the four screws in the cover. 1. Fault Finding Chart WARNING: Before removing the terminal box cover, make sure that the electrical supply has been switched off and that it cannot be accidentally switched on. WARNING: The pumped liquid may be scalding hot and under high pressure.
