5. General description
The pumps are fitted with frequency-controller permanent-magnet
motors for single-phase or three-phase power supply connection.
5.1 Radio communication
This product incorporates a radio module for remote control
which is a class 1 device and can be used anywhere in the EU
member states without restrictions.
For use in USA and Canada, see appendix 1.2 Radio
communication, page 70.
Some variants of the product and products sold in China and
Korea have no radio module.
This product can communicate with the Grundfos GO and other
products of the same type via the built-in radio module.
In some cases, an external antenna may be required.
Only Grundfos-approved external antennas may be connected to
this product, and only by a Grundfos-approved installer.
5.2 Battery
Pumps with the advanced functional module, FM 300, incorporate
a Li-ion battery. The Li-ion battery complies with the Battery
Directive (2006/66/EC). The battery does not contain mercury,
lead and cadmium.

7. Applications
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.
7.1 Pumped liquids
The pump is suitable for thin, clean, non-aggressive and
non-flammable liquids, not containing solid particles or fibers 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.
The EPDM O-rings fitted as standard are primarily suitable for
water.
If the water contains minerals, synthetic oils or chemicals or other
liquids than water are pumped, choose the O-rings accordingly.
8. Mechanical installation
Install the pump in a dry well-ventilated, but frost-free position.
When installing pumps with oval bolt holes in the pump flange,
use washers as shown in fig. 3.
Fig. 3 Use of washers for oval bolt holes
Arrows on the pump casing show the direction of flow of liquid
through the pump.
You can install the pump in horizontal or vertical pipes.
For inspection and removal of motor or pump head, a clearance
of 11.81" (300 mm) is required above the motor. See fig. 4.
Fig. 4 Required clearance above the motor
WARNING
Contact with hazardous liquids
Death or serious personal injury
- 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.
- Wear personal protection equipment.
WARNING
Hot or cold surface
Death or serious personal injury
- Maker sure that no one can accidentally come into
contact with hot or cold surfaces.
In order to maintain the UL mark, additional
requirements apply to the equipment. See Appendix
on page 70.
TM01 0683 1997
The motor must never fall below the horizontal plane.
TM06 0913 1613
Installation
Washer Pump
11.81" [300 mm]

English (US)
Twin-head pumps installed in horizontal pipes must be fitted with
an automatic air vent in the upper part of the pump casing. See
fig. 5.
The automatic air vent is not supplied with the pump.
Fig. 5 Automatic air vent
If the liquid temperature falls below the ambient temperature or
the pump is installed outside, 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 32 °F (0 °C), 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 motor shaft in horizontal position. See fig. 5.
8.1 Pipes
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
pipes are 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 casing is not
stressed by the pipes.
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 pipes on the inlet side of 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.
8.2 Terminal box positions
You can turn the terminal box to any position.
Change the terminal box position as follows:
TM05 7983 1713
TM05 7917 1613
Observe the conditions in section 11. Operating
conditions.
TM00 2263 0195
The pump must not run against a closed outlet valve
as this will cause an increase in temperature or
formation of steam in the pump, which may cause
damage to the pump.
DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply to the motor and to the
signal relays. Wait at least 5 minutes before you
make any connections in the terminal box. Make
sure that the power supply cannot be accidentally
switched on.
WARNING
Hazardous liquids
Death or serious personal injury
- If the pump is used for a liquid which is injurious to
health, it will be classified as contaminated. In
such case, take proper precautions to avoid injury
to health when operating or working on the pump.
- Wear personal protection equipment.
WARNING
Falling objects
Death or serious personal injury
- If the pump head has been lifted partly or
completely from the pump casing, pay special
attention when fitting the pump head again.
CAUTION
Crushing of feet
Minor or moderate personal injury
- Wear safety shoes.
- Pay special attention that the pump head does not
fall down when loosening the clamp. See fig. 8.
WARNING
Pressurised system
Death or serious personal injury
- Pay special attention to escaping vapor when

1. Loosen the clamp securing the pump head to the casing. See
fig. 8.
Fig. 8 Clamp (A)
2. Turn the pump head to the required position.
3. Check the following before you tighten the clamp:
– The contact face of the pumping casing 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 casing. See fig. 11.
Torque: 5.9 lbf-ft (± 0.75) (8 Nm (± 1).
8.3 Fitting of pump head
If for some reasons the pump head has been lifted from the pump
casing, follow the following procedure in order to mount the pump
head correctly:
1. Visually check that the neck ring is centered in the pump
casing. See fig. 9.
Fig. 9 Centering of neck ring
2. Gently lower the pump head with rotor shaft and impeller into
the pump casing. See fig. 10.
Fig. 10 Lowering of pump head
3. Check the following before you tighten the clamp:
