5. Installation and connection
Only install and operate the pump under the operating parameters
and conditions described in Chapter 4, Technical data.
Observe the safety precautions (see Chapter 3).
5.1. Installation
Before installation, store the pump at the installation location to
bring it up to room temperature.
See the data sheet for the mounting dimensions.
Make sure that the installation location is dry and the pump is
protected against rain, splash, hose and drip water.
Install the pump at the highest point in the system to prevent
condensate from collecting in the pump head.
Protect the pump from dust.
Protect the pump from vibrations and jolts.
5.2. Electrical connection
DANGER
Extreme danger from electrical shock
Only have the pump connected by an authorized
specialist.
Only have the pump connected when the power
supply is disconnected.
In the electrical installation, arrangements (complying with EN
60335-1) must be made for disconnecting the pump motor
from the electrical supply.
Connecting pump
1. Compare the supply data with the data on the motor-plate. For
operating current see type plate.
The voltage must not vary by more than + 10% and - 10% from
that shown on the type-plate.
2. Connect the plus and minus pole.
With DC motors, note the proper polarity:
red motor cable: +
black motor cable: -
EMC-compatible Installation (brushless DC motor)
In order to remove the electrical interference according to EN
55014-1:1993 + A1:1997 all pumps with brushless DC motor (DC
B) must be equipped with an additional electronic circuit. This
electronic circuit has to be installed as close to the motor as possi-
ble.
The additional circuitry is not necessary if a voltage supply has a
suppression of > 20 dB at 150 kHz and 0 dB at 1 MHz.
