2.1.1 Read this booklet

This booklet is designed to help a certified installer install, begin operation of and troubleshoot the Grundfos UPS pumps. The booklet 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.

2.1.2 Electrical work

3. Pre-installation checklist

3.1 Confirm you have the correct pump

• Read the pump nameplate to make sure it is the one you ordered.

• Compare the pump's nameplate data and its performance curve (for head, gpm, etc.) with the application in which you plan to install it.

• Will the pump do what you expect it to do?

3.2 Check the condition of the pump

The shipping carton your pump came in is specially designed around your pump during production to prevent damage. As a precaution, it should remain in the carton until you are ready to install it. At that point, look at the pump and examine it for any damage that may have occurred during shipping. Examine any other parts of the shipment as well for any visible damage.

3.3 Verify electrical requirements

Verification of the electrical supply should be made to be certain the voltage, phase and frequency match that of the pump motor. The proper operating voltage and other electrical information can be found on the pump nameplate. These motors are designed to run on + / - 10 % of the nameplate-rated voltage. Wiring connection diagrams can be found inside the terminal box cover and later in these Installation and Operating Instructions. If voltage variations are larger than + / - 10 %, do not operate the pump. Warning All electrical work should be performed by a qualified electrician in accordance with the latest edition of the National Electrical Code, local codes and regulations. Warning A faulty motor or wiring can cause electrical shock that could be fatal, whether touched directly or conducted through standing water. For this reason, proper grounding of the pump to the power supply's grounding terminal is required for safe installation and operation. In all installations, the above- ground metal plumbing should be connected to the power supply ground as described in Article 250-80 of the National Electrical Code. UPS_Series 200_US.book Page 5 Monday, June 18, 2012 3:52 AM6 English (US)

3.4 Pumped liquid requirements

The pump can be used to circulate:

• Water for hydronic heating

• Water/glycol mixtures up to 50/50

• Cooling water In domestic hot-water systems it is advisable to use bronze pumps (UPS model) only for water with a degree of hardness lower than 14 grains per gallon of hardness. For water with a higher degree of hardness, a direct-coupled Grundfos TP pump is recommended. If the pump is installed in a heating system, the water should meet the requirements of accepted standards on water quality in heating systems. In water/glycol mixtures, in order to prevent the glycol from degrading, temperatures above those for which the fluid is rated should be avoided and time spent at high temperatures minimized. It is also important that the system is cleaned and flushed prior to the installation of the glycol mixture. In order to avoid problems with corrosion or precipitation, the glycol fluids should be checked and maintained regularly. If further dilution of the supplied glycol is required, follow the requirements of the supplier of the glycol. DEXCOOL

is a registered trademark of General Motors Corporation, used under license by Texaco Lubricants NA. The pump is lubricated and cooled by the liquid being pumped. Therefore, the pumped liquid must always be allowed to circulate through the pump. Extended periods without circulation will cause premature wear to the bearings and excessive motor heat. The pumped liquid must also meet the following requirements: Minimum pump inlet pressure (during operation) Liquid temperature range Continuously: 14 °F (-10 °C) up to 230 °F (110 °C). Intermittent: < 284 °F (140 °C) for short periods of time. Domestic hot water: < 140 °F (60 °C). Caution The UPS pump is intended for use with water only. Warning Glycol with the trade name DEXCOOL

4. Installation procedures

4.1 Electrical preparation

Terminal box position At the bottom of the stator, closest to the pump housing, there are eight drain holes to allow condensed water to escape. The drain holes shall not be blocked. The drain holes must point downwards. The terminal box must therefore point upwards in one of the positions shown in fig. 1. The following terminal box positions apply whether the piping is mounted vertically or horizontally. Fig. 1 Possible terminal box positions Rotating the terminal box To change the position of the terminal box, follow these steps:

1. Remove the four allen-head screws holding

the pump head onto the pump housing.

2. Carefully lift the pump head and rotate it so

the terminal box is in the desired position. DO NOT locate the terminal box beneath the pump. Make sure the O-ring is properly seated in the pump housing.

3. Replace the pump head onto the pump

4. Tighten the allen-head screws evenly.

Torque: 8 mm: 15 ft lbs 10 mm: 25 ft lbs.

5. Check to make sure the rotor turns freely.

Do this by removing the vent plug in the middle of the pump nameplate. Insert a medium size flat-blade screwdriver into the slot at the exposed end of the shaft. Gently turn the shaft. If it does not turn easily, repeat steps 1 to 4 above.

6. The position of the nameplate can be

changed by easing the outer edge of the plate at the cutout with a screwdriver. Turn the nameplate to the required position and push into place.

7. Refer to page 19 and page 20 for additional

4.2 Piping considerations

Thoroughly clean and flush all dirt and sediment from the system before attempting to install the pump. Location in the piping line The pump should never be located at the lowest point of the piping system, where dirt and sediment collect. Nor should it be located at the highest point of the piping system, where air accumulates. Mounting positions The arrows on the flanges of the pump indicate the direction of water flow. Although the UPS may be installed in either vertical or horizontal piping, the motor shaft must always remain horizontal, as shown in fig. 1 and fig. 2. Fig. 2 Direction of water flow through the pump Warning Never make any connections in the pump terminal box unless the electrical supply has been switched off. TM03 7296 4706 Warning If the pump is already installed in the system, the system must be drained or the isolation valves on both sides of the pump must be closed before the allen-head screws are removed as the pumped liquid may be scalding hot and/or under pressure. Do not start the pump until the system has been filled with liquid and vented. TM03 7290 4706 Note Pumps installed outdoors must be protected by a ventilated, watertight cover to keep out moisture and dirt. Warning The pump must be positioned so that someone cannot accidentally come into contact with the hot surfaces of the pump. UPS_Series 200_US.book Page 7 Monday, June 18, 2012 3:52 AM8 English (US)

4.3 Connect the pump

Install the pump into the piping system. Grundfos recommends that pressure gauges be installed in the inlet and discharge flanges or pipes to check pump and system performance.

4.4 Electrical connection

The electrical connection and protection should be carried out in accordance with the latest edition of the National Electrical Code, local codes and regulations by a qualified electrician. The operating voltage and frequency are marked on the pump nameplate. Make sure that the motor is suitable for the electrical supply it is being installed to. The pump should be grounded to protect against indirect contact and a ground fault interrupter can be used as extra protection. Multi-speed pump (single-phase) All single-phase pumps are equipped with built-in, automatic resetting, thermal overload protection. The pump is protected at all three speeds. Multi-speed pump (three-phase) The pump must be connected to the electrical supply via an external contactor. The contactor must be connected to the built-in thermal overload switch terminals T1 and T2 (3 x 208-230 V) or P1 and P2 (3 x 460 V and 575 V) to protect the pump against overloading at all three speeds. OR: If the pump is protected by means of a motor starter, the starter must be set to the current consumption of the pump at the selected speed. The motor starter setting must be changed every time the pump speed is changed. The current consumption at the individual speeds is stated on the pump nameplate. Figures 4, 6, 7, 9, and 10 on the next pages show the possible connections.

5. Starting the pump

5.1 Vent the piping system

After the pump has been installed and the electrical connections made, the piping system must be vented. Instead, follow these steps:

1. Fill and pressurize the system with liquid,

and vent all trapped air from the piping by suitable means.

2. If any isolation valves are used, make sure

Applies to 460 V and 575 V two-speed models only (The direction of rotation of three-speed pumps is checked by means of the fault finding chart, page 13 and page 14).

1. Make sure that the power is OFF.

2. Unscrew and remove the vent plug located

at the center of the nameplate.

3. Insert a small, flat-blade screwdriver into the

slot in the end of the motor shaft (see fig. 12). Rotate the shaft with the screwdriver to make sure it does so freely.

4. Bump the pump and watch to see which

direction the shaft rotates. The shaft must rotate in the counterclockwise direction as shown on the nameplate (see fig. 11).

5. If the pump shaft is rotating incorrectly,

disconnect the power and interchange any two power leads in the terminal box.

6. Check once again for proper

counterclockwise rotation. When it is rotating correctly, replace the vent plug.

6.2 Preliminary checks

Supply voltageTo check the voltage being supplied to the motor, use a voltmeter. Fig. 17 Checking single-phase powerEvaluationWhen the motor is under load, the voltage should be within 10 % (+ or -) of the nameplate voltage. Any variation larger than this may indicate a poor electrical supply and can cause damage to the motor windings. The motor should not be operated under these conditions. Contact your power supplier to correct the problem or change the motor to one requiring the voltage you are receiving.7. Single-phase pumps with protection module (only). The pump does not run. The red indicator light is on. The green indicator light is off. a) The pump has been cut out by the thermal overload switch due to high liquid temperature or blocked rotor.Check that the liquid temperature falls within the specified range. The pump will restart automatically when it has cooled to normal temperature.NOTE: If the thermal overload switch has cut out the pump three times within a short period, the pump must be restarted manually by switching off the electrical supply. b) The speed switch module has not been fitted.Switch off the electrical supply by means of the external mains switch and fit the speed switch module.Fault Cause RemedyWarningBe 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. Single-phase motors Three-phase motorsTouch one voltmeter lead to each of the lines supplying power to the pump:• L and N for 115 V circuits• L1 and L2 for 230 V circuits.Touch a voltmeter lead to:• Power leads L1 and L2• Power leads L2 and L3• Power leads L3 and L1.These tests should give a reading of full line voltage.TM03 7749 4806
