General Information; Radio Communication; Battery; Mechanical Installation - Grundfos TPE Series Installation And Operating Instructions Manual

4. General information

These installation and operating instructions apply to the
Grundfos TPE pumps.
The pumps are fitted with frequency-controlled
permanent-magnet motors for single-phase or three-phase mains
connection.

4.1 Radio communication

For installation in the USA and Canada, see also page 33.
This product can communicate with the Grundfos GO Remote
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.

4.2 Battery

Pumps fitted 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.

5. Mechanical installation

Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.

5.1 Mounting

The pump must be secured to a solid foundation by bolts through
the holes in the flange or the base plate.
In order to maintain the UL mark, additional
Note
Note
installation procedures must be followed.
See page 33.

5.2 Cable entries

plugs from factory.
The following cable glands are included:
2 x M20 cable gland, cable diameter ∅0.016" (5 mm)
•
1 x M20 cable gland, cable diameter ∅0.023 - 0.046"

5.3 Ensuring motor cooling

In order to ensure sufficient cooling of the motor,
the distance (D) between the end of the fan cover

and a wall or other fixed objects must always be
at least 0.16" (50 mm), irrespective of motor size.
See fig. 1.

fixed objects

5.4 Outdoor installation

When installed outdoors, the motor must be provided with a
suitable cover to avoid condensation on the electronic
components. See fig. 2.
When fitting a cover to the motor, observe the
Note
Note
guideline in section 5.3 Ensuring motor cooling.
The cover must be sufficiently large to ensure that the motor is
not exposed to direct sunlight, rain or snow. Grundfos does not
supply covers. We therefore recommend that you have a cover
built for the specific application. In areas with high air humidity,
we recommend that you enable the built-in standstill heating
function.

5.5 Drain holes

When the motor is installed in moist surroundings or areas with
high air humidity, the bottom drain hole should be open.
The enclosure class of the motor will then be lower. The open
drain hole helps prevent condensation in the motor as it will make
the motor self-venting and allow water and humid air to escape.
The motor has a plugged drain hole on the drive side. The flange
can be turned 90 ° to both sides or 180 °.
