Preparation; Mechanical Installation - Grundfos BM Installations- Und Bedienungsanleitungen

4. Preparation

Before installation, the following checks must be made:
1. Check for transport damages
Make sure that the module has not been damaged during
transportation.
2. Type of module
Check that the type designation given on the nameplate fitted
to the sleeve corresponds to the order.
3. Power supply
The motor voltage and frequency are marked on the
nameplate. Make sure that the motor is suitable for the power
supply on which it will be used.
4. Liquid in motor
If a module has been stored for more than one year, check the
motor liquid and refill, if required. Contact Grundfos. If a
module is supplied for a special system, the motor may be
supplied without liquid or with demineralised water. See
section 3. Delivery, transportation and

5. Mechanical installation

Grundfos booster modules are as standard supplied without a
built-in non-return valve. However, a non-return valve can be built
in on request. See fig. 7.
In systems involving the risk of water hammer in connection with
start/stop, the necessary measures must be taken to minimise
this risk.
The booster modules are suitable for both vertical and horizontal
installation, however, the outlet port must never fall below the
horizontal plane. See fig. 3.
storage. An arrow on the module sleeve shows the direction of flow of
liquid through the module. See fig. 2.
The module is fastened by means of clamps. See fig. 5.
WARNING
Electric shock
Death or serious personal injury
- The electrical installation must be carried out by an
authorised person in accordance with local
regulations.
WARNING
Falling objects
Death or serious personal injury
- Observe local regulations concerning limits for
manual lifting or handling. See weight on the
nameplate.
- Note that the module has an uneven weight
distribution. Because of the motor, the largest
weight will be in the first third of the sleeve (when
seen from the outlet port).
- Use straps on the motor, and do not lift the pump
by the terminal box.
- Use certified and approved lifting equipment.
