10. Technical data
10.1 Operating conditions
The ambient temperature must be between -20 to +40 °C, and the
relative humidity must be less than 90 %. The maximum altitude is
1000 m above sea level.
In case of deviation from the above operating conditions,
such as ambient temperature below -20 or above +40 °C,
relative humidity above 90 %, altitude more than 1000 m
above sea level or a high vibration, check the the suitabili-
ty of the motor for the operation. For more information,
contact your local Grundfos company.
The deviation between the supply frequency and the rated
frequency must not exceed 2 %, and the deviation between the
supply voltage and the rated voltage must not exceed 5 % (except
for special designs according to agreements).
Open drip-proof motors (IP23, IP21) are suitable for operating in
clean, dry, well-ventilated and corrosion-free indoor environments.
For more information, see IEC 60034-1.
Totally enclosed fan-cooled motors (IP44, IP54, IP55) are suitable
for operating in relatively dirty, humid or dusty environments. For
more information, see IEC 60034-1.
Outdoor anticorrosion motors are suitable for operating outdoors or
in corrosive and high humidity environments.
Adequate ventilation of the motor must be ensured under
all working conditions. If there are other ventilators, make
sure that they do not affect the effective ventilation of the
motor. If motor ventilation is affected, the air volume of the
ventilator must be adjusted or the ventilation path of the
motor must be changed to ensure effective motor ventila-
tion.
11. Disposing of the product
This product or parts of it must be disposed of in an environmentally
sound way.
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest Grundfos company or
service workshop.
The crossed-out wheelie bin symbol on
a product means that it must be dis-
posed of separately from household
waste. When a product marked with
this symbol reaches its end of life, take
it to a collection point designated by
the local waste disposal authorities.
The separate collection and recycling
of such products will help protect the
environment and human health.
