5. Applications

Note

Caution

Installation

Washer

Pump

300 mm

The pumps are designed to circulate hot or cold water in residential, institutional and industrial applications:

• heating systems

• district heating plants

• central heating systems for blocks of flats

• air-conditioning systems

• cooling systems. In addition, the pumps are used for liquid transfer and water

supply in for instance:

• washing systems

• domestic hot-water systems

• industrial systems in general. To ensure optimum operation, the dimensioning range of the

system must fall within the performance range of the pump.

6. Mechanical installation

Warning When pumping hot or cold liquids, make sure that

persons cannot accidentally come into contact with hot or cold surfaces.

In order to maintain the UL mark, follow the additional installation procedures. See page 66.

Install the pump in a dry well-ventilated, but frost-free position. When installing pumps with oval bolt holes in the pump flange

(PN 6/10), use washers as shown in fig. 3.

English (GB)

5.1 Pumped liquids

Warning If the pump is used for a liquid which is injurious to

health, it will be classified as contaminated. In such cases, take proper precautions to avoid injury to health when operating or working on the pump.

The pump is suitable for thin, clean, non-aggressive and non-flammable liquids, not containing solid particles or fibres that may attack the pump mechanically or chemically.

Examples:

• Central heating system water (the water must meet the requirements of accepted standards on water quality in heating systems)

• cooling liquids

• domestic hot water

• industrial liquids

• softened water.

The pumping of liquids with a density and/or kinematic viscosity higher than that of water will have the following effects:

• a considerable pressure drop

• a drop in hydraulic performance

• a rise in power consumption.

In such cases, fit the pump with a bigger motor. If in doubt, contact Grundfos.

The EPDM O-rings fitted as standard are primarily suitable for water.

If the water contains mineral/synthetic oils or chemicals or if other liquids than water are pumped, chose the O-rings accordingly.

TM01 0683 1997

Fig. 3 Use of washers for oval bolt holes

Arrows on the pump housing show the direction of flow of liquid through the pump.

The pump can be installed in horizontal or vertical pipes.

The motor must never fall below the horizontal plane.

For inspection and removal of motor or pump head, a clearance of 300 mm is required above the motor. See fig. 4.

TM05 7916 1613TM05 7983 1713

Fig. 4 Required clearance above the motor

Twin-head pumps installed in horizontal pipes must be fitted with an automatic air vent in the upper part of the pump housing. See fig. 5.

The automatic air vent is not supplied with the pump.

condensation may form in the motor during standstill. In this case, make sure that one of the drain holes in the motor flange is open and points downwards. See fig. 6.

Fig. 6 Drain hole in motor flange

If twin-head pumps are used for pumping liquids with a temperature below 0 °C (32 °F), condensed water may freeze and cause the coupling to get stuck. You can solve the problem by installing heating elements. Whenever possible, install the pump with the motor shaft in horizontal position. See fig. 5.

Observe the conditions in section 9. Operating

conditions.

6.1 Pipework

Fit isolating valves on either side of the pump to avoid draining the system if the pump needs to be cleaned or repaired.

The pump is suitable for pipeline mounting, provided that the pipework is adequately supported on either side of the pump.

Single-head pumps are designed for pipeline mounting only. Twin-head pumps are prepared for installation on a mounting

bracket or base plate. When installing the pipes, make sure that the pump housing is

not stressed by the pipework. The inlet and outlet pipes must be of an adequate size, taking the

pump inlet pressure into account. To avoid sediment build-up, do not fit the pump at the lowest point

of the system. Install the pipes so that air locks are avoided, especially on the

inlet side of the pump. See fig. 7.

Fig. 7 Correct pipework on the inlet side of the pump

6.2 Terminal box positions

TM05 7917 1613

You can turn the terminal box to any position. Change the terminal box position as follows:

1. Loosen the clamp securing the pump head to the pump housing. See fig. 8.

head must be in full contact.

of both the pump head and the pump housing. See fig. 11.

TM06 0721 0814

The pump must not run against a closed outlet valve or this will cause an increase in temperature/formation of steam in the pump which may cause damage to the pump.

If there is any risk of the pump running against a closed outlet valve, ensure a minimum liquid flow through the pump by connecting a bypass or a drain to the outlet pipe. The drain can for instance be connected to a tank. A minimum flow rate of 10 % of the flow rate at maximum efficiency is needed at all times.

Flow rate and head at maximum efficiency are stated on the pump nameplate.

Page 7

6.3 Fitting of pump head

Caution

Warning Before starting work on the pump, make sure that the

power supply has been switched off for at least 5 minutes. Make sure that the power supply cannot be accidentally switched on.

Warning If the pump head has been lifted partly or completely

from the pump housing, pay special attention when fitting the pump head again. See instructions below.

Warning Do not drop the pump head. See fig. 8.

Warning When loosening the clamp, there is a risk of

escaping vapour. See fig. 8.

If for some reason the pump head has been lifted from the pump housing, follow the following procedure in order to mount the pump head correctly:

1. Visually check that the neck ring is centred in the pump housing. See fig. 9.

3. Check the following before you tighten the clamp: – The contact face of the pump housing and that of the pump

head must be in full contact.

– The clamp must be positioned correctly in the flange recess

of both the pump head and the pump housing. See fig. 11.

7.3 Additional protection

Note

ELCB (GFCI)

Note

English (GB)

7.3.1 Single-phase motors

If the motor is connected to an electric installation where an earth leakage circuit breaker (ELCB) or ground fault circuit interrupter (GFCI) is used as additional protection, this circuit breaker or interrupter must be marked with the following symbol:

When an earth leakage circuit breaker or ground fault circuit interrupter is selected, take the total leakage current of all the electrical equipment in the installation into account.

You find the leakage current of the motor in section 27.2 Leakage

current.

7.3.2 Three-phase motors

• It must be suitable for handling leakage currents and cutting-in

with short pulse-shaped leakage.

• It must trip out when AC fault currents and fault currents with

DC content, i.e. pulsating DC and smooth DC fault currents, occur.

For these motors, use an earth leakage circuit breaker or ground fault circuit interrupter, type B.

The circuit breaker or interrupter must be marked with the following symbols:

When an earth leakage circuit breaker or ground fault circuit interrupter is selected, take the total leakage current of all the electrical equipment in the installation into account.

You find the leakage current of the motor section 28.2 Leakage

current.

Protection against phase unbalance

Connect the motor to a power supply with a quality corresponding to IEC 60146-1-1, class C, to ensure correct motor operation at phase unbalance.

This also ensures long life of the components.

7.4 Connection terminals

The descriptions and terminal overviews in this section apply to both single-phase and three-phase motors.

For maximum tightening torques, see section Torques, page 63. The number of terminals depends on the functional module. See

section 22. Identifying the functional module.

7.4.1 Connection terminals, advanced functional module, FM 300

The advanced functional module is only available as an option. The advanced module has these connections:

• three analog inputs

Caution

English (GB)

• Use screened cables with a cross-sectional area of minimum

0.5 mm

and maximum 1.5 mm2 for external on/off switch,

digital inputs, setpoint and sensor signals.

• Connect the screens of the cables to frame at both ends with good connection. The screens must be as close as possible to the terminals. See fig. 21.

Fig. 21 Stripped cable with screen and wire connections

• Always tighten screws for frame connections whether a cable is fitted or not.

• The wires in the motor terminal box must be as short as possible.

7.6 Bus connection cable

7.6.1 New installations

For the bus connection, use a screened 3-core cable with a cross-sectional area of minimum 0.5 mm

• If the motor is connected to a unit with a cable clamp which is identical to the one on the motor, connect the screen to this cable clamp.

• If the unit has no cable clamp as shown in fig. 22, leave the screen unconnected at this end.

8. Startup

8.1 Flushing the pipe system

The pump is not designed to pump liquids containing solid particles such as pipe debris and welding slag. Before starting up the pump, clean the pipe system thoroughly, and flush and fill it with clean water.

The warranty does not cover any damage caused by flushing the pipe system by means of the pump.

8.2 Priming the pump

Do not start the pump until it has been filled with liquid and vented. To ensure correct venting, the vent screw should point upwards.

Closed systems or open systems where the liquid level is above the pump inlet

1. Close the outlet isolating valve and loosen the vent screw in

TM02 1325 4402 TM05 3973 1812TM02 8842 0904

the motor stool. See fig. 24.

Warning Pay attention to the direction of the vent hole, and

make sure that the escaping hot or cold liquid does not cause injury to persons or damage to the equipment.

2. Slowly open the isolating valve in the inlet pipe until a steady stream of liquid runs out of the vent hole.

3. Tighten the vent screw and completely open the isolating valve(s).

Open systems where the liquid level is below the pump inlet

The inlet pipe and the pump must be filled with liquid and vented before the pump is started.

1. Close the outlet isolating valve and open the isolating valve in the inlet pipe.

2. Loosen the vent screw. See fig. 24.

3. Remove the plug from one of the pump flanges, depending on the pump location.

4. Pour liquid through the priming port until the inlet pipe and the pump are filled with liquid.

5. Replace the plug and tighten securely.

6. Tighten the vent screw.

You can fill the inlet pipe with liquid and vent it before you connect it to the pump. You can also install a priming device before the pump.

7.6.2 Replacing an existing motor

• If a screened 2-core cable is used in the existing installation, connect the cable as shown in fig. 23.

Fig. 23 Connection with screened 2-core cable

• If a screened 3-core cable is used in the existing installation, follow the instructions in section 7.6.1 New installations.

TM05 7922 1613

Page 15

8.3 Starting the pump

Note

1. Before starting the pump, completely open the isolating valve

on the inlet side of the pump and leave the outlet isolating valve almost closed.

2. Start the pump. See section 10. User interfaces.

3. Vent the pump by loosening the vent screw in the motor stool

until a steady stream of liquid runs out of the vent hole. See fig. 24.

Warning Pay attention to the direction of the vent hole, and

make sure that the escaping hot or cold liquid does not cause injury to persons or damage to the equipment.

4. When the pipe system has been filled with liquid, slowly open

the outlet isolating valve until it is completely open.

8.4 Shaft seal run-in

The seal faces are lubricated by the pumped liquid, meaning that there may be a certain amount of leakage from the shaft seal.

When the pump is started up for the first time, or when a new shaft seal is installed, a certain run-in period is required before the leakage is reduced to an acceptable level. The time required for this depends on the operating conditions, i.e. every time the operating conditions change, a new run-in period will be started.

Under normal conditions, the leaking liquid will evaporate. As a result, no leakage will be detected.

However, liquids such as kerosene will not evaporate. The leakage may therefore be seen as a shaft seal failure.

9. Operating conditions

9.1 Maximum number of starts and stops

The number of starts and stops via the power supply must not exceed four times per hour.

When switched on via the power supply, the pump will start after approx. 5 seconds.

If a higher number of starts and stops is desired, use the input for external start/stop when starting/stopping the pump.

When started via an external on/off switch, the pump will start immediately.

9.2 Alternating operation of twin-head pumps

On twin-head pumps, the duty and backup pumps must be alternated on a regular basis, i.e. once a week, to ensure an even distribution of the operating hours on both pumps. The pumps alternate automatically. See section 14.47 Multipump setup

(Setup of multi-pump system).

If twin-head pumps are used for pumping domestic hot water, the duty and backup pumps must be alternated on a regular basis, i.e. once a day, to avoid blocking of the backup pump due to deposits (calcareous deposits, etc.). The pumps alternate automatically. See section 14.47 Multipump setup (Setup of

multi-pump system).

9.3 Liquid temperature

-25 °C (~ -13 °F) up to +120 °C (~ +248 °F). The maximum liquid temperature depends on the shaft seal type

and the pump type. Depending on the cast-iron version and the pump application, the

maximum liquid temperature may be limited by local regulations and laws.

The maximum liquid temperature is stated on the pump nameplate.

If the pump is used for liquids at high temperatures, the life of the shaft seal and the built-in Grundfos sensor may be reduced.

9.4 Ambient temperature

9.4.1 Ambient temperature during storage and transportation

-30 - +60 °C.

9.4.2 Ambient temperature during operation

-20 - +50 °C. The motor can operate with the rated power output, P2, at 50 °C,

but continuous operation at higher temperatures will reduce the expected product life. If the motor is to operate at ambient temperatures between 50 and 60 °C, select an oversized motor. Contact Grundfos for further information.

9.5 Operating pressure/test pressure

The pressure test has been made with water containing anti-corrosive additives at a temperature of 20 °C (~ 68 °F).

PN 16 16 1.6 24 2.4

9.6 Inlet pressure

To ensure optimum and quiet pump operation, the inlet pressure, system pressure, must be adjusted correctly. See the table on page 67.

For the calculation of specific inlet pressures, contact the local Grundfos company or see the data booklet for TP, TPD, TPE, TPED, TPE2, TPE2 D, TPE3 and TPE3 D on Grundfos Product Center (https://product-selection.grundfos.com/).

9.7 Electrical data

See sections 27. Technical data, single-phase motors and

28. Technical data, three-phase motors.

For specific motor data, see the motor nameplate.

14.1 Heat energy meter

Pump variant Heat energy meter

TPE3, TPE3 D  TPE2, TPE2 D -

The heat energy meter is a monitoring function that calculates the heat energy consumption within a system. The built-in flow estimation needed for the calculation has an inaccuracy of ± 10 % of the maximum flow in the area down to 10 % flow and down to

12.5 % of the maximum head. The calculations are based on water at a temperature of 20 °C. Also, the temperature measurements needed for the calculation have some inaccuracy depending on the sensor type. Therefore, you cannot use the heat energy value for billing purposes. However, the value is perfect for optimisation purposes in order to prevent excessive energy costs caused by system imbalances.

The heat energy meter requires an additional temperature sensor installed in the flow pipe or return pipe depending on where the pump is installed.

14.3 Operating mode

Possible operating modes:

•Normal The pump runs according to the selected control mode.

•Stop The pump stops.

•Min. The minimum curve mode can be used in periods in which a minimum flow is required. This operating mode is for instance suitable for manual night setback if you do not want to use automatic night setback.

•Max. The maximum curve mode can be used in periods in which a maximum flow is required. This operating mode is for instance suitable for systems with hot-water priority.

• Manual The pump is operating at a manually set speed. In "Manual" the setpoint via bus is overruled. See section 14.4 Set manual

All operating modes are illustrated in the figure below.

The head of the pump is reduced at decreasing water demand and increased at rising water demand. See fig. 38.

This control mode is especially suitable in systems with relatively large pressure losses in the distribution pipes. The head of the pump will increase proportionally to the flow in the system to compensate for the large pressure losses in the distribution pipes.

The setpoint can be set with an accuracy of 0.1 metre. The head against a closed valve is half the setpoint.

14.7 Automatic Night Setback

Pump variant Automatic Night Setback

TPE3, TPE3 D  TPE2, TPE2 D -

Once you have enabled automatic night setback, the pump automatically changes between normal duty and night setback (duty at low performance).

Changeover between normal duty and night setback depends on the flow-pipe temperature.

The pump automatically changes over to night setback when the built-in sensor registers a flow-pipe temperature drop of more than 10 to 15 °C within approx. two hours. The temperature drop must be at least 0.1 °C/min.

Changeover to normal duty takes place without a time lag when the temperature has increased by approx. 10 °C.

Function

Select one of these functions:

•Not active When set to "Not active", the input has no function.

• External stop When the input is deactivated (open circuit), the pump will stop.

• Min. (minimum speed) When the input is activated, the pump will run at the set min. speed.

• Max. (maximum speed) When the input is activated, the pump will run at the set maximum speed.

• External fault When the input is activated, a timer will be started. If the input is activated for more than 5 seconds, the pump will be stopped and a fault will be indicated. This function depends on input from external equipment.

• Alarm resetting When the input is activated, a possible fault indication will be reset.

• Dry running When this function has been selected, lack of inlet pressure or water shortage can be detected. When lack of inlet pressure or water shortage (dry running) is detected, the pump will be stopped. The pump cannot restart as long as the input is activated. This requires the use of an accessory, such as:

– a pressure switch on the inlet side of the pump

TM06 4012 1515

– a float switch on the inlet side of the pump.

• Accumulated flow When this function has been selected, the accumulated flow can be registered. This requires the use of a flowmeter which can give a feedback signal as a pulse per defined flow of water. See section 14.21 Pulse flowmeter setup.

• Predefined setpoint digit 1 (applies only to digital input 2) When digital inputs are set to a predefined setpoint, the pump will operate according to a setpoint based on the combination of the activated digital inputs. See section 14.18 Predefined

setpoints.

Pump variant Temperature influence

TPE3, TPE3 D  TPE2, TPE2 D -

When this function is enabled in proportional- or constant-pressure control mode, the setpoint for head will be reduced according to the liquid temperature.

Temperature influence can be set to function at liquid temperatures below 80 or 50 °C. These temperature limits are called T 100 %) according to the characteristics below.

Fig. 69 Temperature influence

In the above example, T actual liquid temperature, T be reduced from 100 % to H

The temperature influence function requires the following:

• proportional-pressure or constant-pressure control mode

• pump installed in flow pipe

• system with flow-pipe temperature control.

Temperature influence is suitable for the following systems:

• Systems with variable flows, for example two-pipe heating systems, in which the enabling of the temperature influence function will ensure a further reduction of the pump performance in periods with small heating demands and consequently a reduced flow-pipe temperature.

• Systems with almost constant flows (for example one-pipe heating systems and underfloor heating systems) in which variable heating demands cannot be registered as changes in the head as is the case with two-pipe heating systems. In such systems, the pump performance can only be adjusted by enabling the temperature influence function.

Selecting the maximum temperature

In systems with a dimensioned flow-pipe temperature of:

• up to and including 55 °C, select T

• above 55 °C, select T

Time [s]

Pump variant Limit-exceeded function

TPE3, TPE3 D TPE2, TPE2 D 

This function can monitor a measured parameter or one of the internal values such as speed, motor load or motor current. If a set limit is reached, a selected action can take place. You can set two limit-exceeded functions meaning that you can monitor two parameters or two limits of the same parameter simultaneously.

The function requires setting of the following:

Measured

Here you set the measured parameter to be monitored.

Limit

Here you set the limit which activates the function.

Hysteresis band

Here you set the hysteresis band.

Limit exceeded when

Here you can set if you want the function to be activated when the selected parameter exceeds or drops below the set limit.

• Above limit The function is activated if the measured parameter exceeds the set limit.

• Below limit The function is activated if the measured parameter drops below the set limit.

Action

If the value exceeds a limit, you can define an action. You can select the following actions:

• No action The pump remains in its current state. Use this setting if you only want to have a relay output when the limit is reached. See section 14.13 Signal relays 1 and 2 (Relay outputs).

• Warning/alarm There is a warning.

•Stop The pump stops.

•Min. The pump reduces speed to minimum.

•Max. The pump increases speed to maximum.

Detection delay

You can set a detection delay which ensures that the monitored parameter stays above or below a set limit in a set time before the function is activated.

Resetting delay

The resetting delay is the time from which the measured parameter differs from the set limit including the set hysteresis band and until the function is reset.

Example

The function is to monitor the outlet pressure of a pump. If the pressure is below 5 bar for more than 5 seconds, a warning must be given. If the outlet pressure is above 7 bar for more than 8 seconds, you must reset the warning.

• deceleration time, 0.1 to 300 s.

The times apply to the acceleration from 0 rpm to maximum (fixed) speed and the deceleration from maximum (fixed) speed to 0 rpm.

At short deceleration times, the deceleration of the motor may depend on load and inertia as there is no possibility of actively braking the motor.

If the power supply is switched off, the deceleration of the motor only depends on load and inertia.

You can use the function to avoid condensation in humid environments. When you set the function to "Active" and the pump is in operating mode "Stop", a low AC voltage will be applied to the motor windings. The applied voltage is not high enough to make the motor rotate but will ensure that sufficient heat is generated to avoid condensation in the motor including the electronic parts in the drive.

Remember to remove the drain plugs and fit a cover over the motor.

start counting the mileage of the bearings.

The counter will continue counting even if the function is changed to "Not active", but a warning will not be given when it is time for replacement.

When the function is changed to "Active" again, the accumulated mileage will again be used to calculate the replacement time.

14.47 Multipump setup (Setup of multi-pump system)

Multipump setup

Pump variant

TPE3, TPE3 D  TPE2, TPE2 D 

The multipump function enables the control of two pumps connected in parallel without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

A multipump system is set via a selected pump, i.e. the master pump (first selected pump).

If two pumps in the system are configured with an outlet-pressure sensor, both pumps can function as master pumps and take over the master pump function if the other fails. This provides additional redundancy in the multipump system.

The multipump functions are described in the following sections.

14.47.1 Alternating operation

Alternating operation functions as a duty/standby operating mode and is possible with two pumps of same size and type connected in parallel. The main purpose of the function is to ensure an even amount of running hours and to ensure that the standby pump takes over if the running pump stops due to an alarm.

Each pump requires a non-return valve in series with the pump. You can choose between two alternating operation modes:

• Alternating operation, time

Pump changeover to the other is based on time.

• Alternating operation, energy

Pump changeover to the other is based on energy consumption.

If the duty pump fails, the other pump will take over automatically.

14.47.2 Backup operation

Backup operation is possible with two pumps of same size and type connected in parallel. Each pump requires a non-return valve in series with the pump.

One pump is operating continuously. The backup pump is operated for a short time each day to prevent seizing up. If the duty pump stops due to a fault, the backup pump will start automatically.

14.47.3 Cascade operation

Cascade operation ensures that the pump performance is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and a limited number of pumps.

When a twin-head pump is running in constant-pressure control mode, the second pump head will start at 90 % and stop at 50 % performance.

All pumps in operation will run at equal speed. Pump changeover is automatic and depends on energy, operating hours and fault.

Pump system:

• Twin-head pump.

• Two to four single-head pumps connected in parallel.

The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.

The control mode must be set to "Const. pressure" or "Const. curve".

Main pumps in boiler applications where a steady flow through the boiler is required. No extra energy is used for pumping too much liquid into the system.

In systems with mixing loops, you can use the control mode to control the flow in each loop.

Benefits

• Enough water for all loops at peak load conditions if you have set each loop to the right maximum flow.

• When the flow is set lower than the balancing valve setting, the pump will ramp down instead of losing energy by pumping against a balancing valve.

• Cooling surfaces in air-conditioning systems can operate at high pressure and low flow.

In systems with relatively large pressure losses in the distribution pipes and in air-conditioning and cooling systems.

• Two-pipe heating systems with thermostatic valves and – very long distribution pipes – strongly throttled balancing valves – differential-pressure regulators – large pressure losses in those parts of the system through which the total quantity of

water flows (for example boiler, heat exchanger and distribution pipe up to the first branching).

• Primary circuit pumps in systems with large pressure losses in the primary circuit.

• Air-conditioning systems with – heat exchangers (fan coils) – cooling ceilings – cooling surfaces.

In systems with relatively small pressure losses in the distribution pipes.

• Two-pipe heating systems with thermostatic valves and – dimensioned for natural circulation – small pressure losses in those parts of the system through which the total quantity of

water flows (for example boiler, heat exchanger and distribution pipe up to the first branching) or

– modified to a high differential temperature between flow pipe and return pipe (for example

district heating).

• Underfloor heating systems with thermostatic valves.

• One-pipe heating systems with thermostatic valves or balancing valves.

• Primary circuit pumps in systems with small pressure losses in the primary circuit.

In systems with a fixed system characteristic.

If an external controller is installed, the pump is able to change from one constant curve to another, depending on the external signal.

You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump:

• You can use the maximum curve mode in periods in which a maximum flow is required. This operating mode is for instance suitable for hot-water priority.

• You can use the minimum curve mode in periods in which a minimum flow is required. This operating mode is for instance suitable for manual night setback if you do not want automatic night setback.

Constant curve

In systems requiring a constant flow, independently of pressure drop.

Examples

• chillers for air-conditioning

• heating surfaces

• cooling surfaces.

In systems requiring a constant tank level, independently of the flow rate.

Examples

• process water tanks

• boiler condensate tanks.

In systems with pumps connected in parallel. The multipump function enables the control of two to four single-head pumps connected in

parallel and twin-head pumps without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

17. Bus signal

Note

English (GB)

The pump supports serial communication via an RS-485 input. The communication is carried out according to Grundfos GENIbus protocol and enables connection to other pumps as well as a building management system or another external control system.

Via a bus signal, you can remote-set pump operating parameters, such as setpoint and operating mode. At the same time, the pump can, via the bus, provide status information about important parameters, such as actual value of control parameter, input power and fault indications.

Contact Grundfos for further information.

If you use a bus signal, the number of settings available via Grundfos GO will be reduced.

18. Priority of settings

You can always set the pump to stop by pressing on the pump control panel. When the pump is not in "Stop" mode, you can always stop the pump by continuously pressing . Furthermore, you can set the pump to maximum speed by continuously pressing . You can always set the pump to operation at maximum speed or to stop with Grundfos GO.

If two or more functions are enabled at the same time, the pump will operate according to the function with the highest priority.

Example

24. Maintenance and service

English (GB)

Warning Before starting work on the pump, make sure that the

power supply has been switched off for at least 5 minutes. Make sure that the power supply cannot be accidentally switched on.

Warning Make sure that the escaping water does not cause

injury to persons or damage to the equipment.

Warning If the pump is used for a liquid which is injurious to

health, it will be classified as contaminated. In such cases, the proper precautions must be taken to avoid injury to health when operating or working on the pump.

24.1 Maintenance

24.1.1 Pump

The pump is maintenance-free. If the pump is to be drained for a long period of inactivity, inject a

few drops of silicone oil on the shaft between the motor stool and the coupling. This will prevent the shaft seal faces from sticking.

24.1.2 Motor

Check the motor at regular intervals. It is important to keep the motor clean in order to ensure adequate ventilation. If installed in a dusty environment, clean and check the pump regularly.

24.2 Service

If Grundfos is requested to service the pump, you must clean it must before returning it. If you cannot clean the pump properly, then provide Grundfos with all relevant information about the pumped liquid.

If the above is not fulfilled, Grundfos can refuse to accept the pump for service.

Possible costs of returning the pump are to be paid by the customer.

24.2.1 Integral shaft/coupling

TPE2 and TPE3 pumps have integral shaft/coupling. We recommend that you do not remove the motor.

If the motor has been removed, you must remove the motor stool in order to refit the motor correctly. Otherwise the shaft seal may be damaged.

24.2.2 Blanking flanges

For twin-head pumps, a blanking flange with a pump housing gasket is available. See fig. 89.

Fig. 89 Fitting the blanking flange

If one pump requires service, fit the blanking flange to allow the other pump to continue operating.
