2.1 Inspect the delivery

1. Check the outside of the package for evident signs of damage.

2. Notify our distributor within eight days of the delivery date, if the

product bears visible signs of damage.

Unpack the unit

1. Follow applicable step:

• If the unit is packed in a carton, remove the staples and open the

carton.

• If the unit is packed in a wooden crate, open the cover while pay-

ing attention to the nails and straps.

2. Remove the securing screws or the straps from the wooden base.

Inspect the unit

1. Remove packing materials from the product.

Dispose of all packing materials in accordance with local regulations.

2. Inspect the product to determine if any parts have been damaged or

are missing.

2.2 Transportation guidelines

Precautions

WARNING:

• Observe accident prevention regulations in force.

• Crush hazard. The unit and the components can be heavy.

Use proper lifting methods and wear steel-toed shoes at all

times.

Check the gross weight that is indicated on the package in order to select

proper lifting equipment.

Position and fastening

The unit can be transported either horizontally or vertically. Make sure that

the unit is securely fastened during transportation, and cannot roll or fall

over.

WARNING:

Do not use eyebolts screwed on the motor for handling the

whole electric pump unit.

• Use straps surrounding the motor if the power of the motor is between

0.25 kW and 4.0 kW.

• Use ropes or straps that are linked to the two flanges (eye bolts if provi-

ded) located near the mating zone between the motor and pump, if the

power of the motor is between 5.5 kW and 55.0 kW.

• Eyebolts screwed onto the motor may be exclusively used to handle the

individual motor or, in case of a not balanced distribution of weights, to

partially lift the unit vertically starting from a horizontal displacement.

• To move the pump unit only, use straps firmly linked to the motor adapt-

er.

For more information about how to securely harness the unit, see Figure 4.

Unit without motor

If the unit is not delivered with a motor, the calibrated fork-shaped shim is

already inserted between the adapter and the transmission coupling. The

shim is inserted to keep the impeller stack in the correct axial position. In

order to prevent damage during transportation the shaft is also held into

place with expanded polystyrene and plastic straps.

The bolt and nuts used to fasten the motor are not included. For more in-

formation about how to couple the motor, see Figure 23.

WARNING:

A pump and motor that are purchased separately and then cou-

pled together results in a new machine under the Machinery di-

rective 2006/42/EC. The person making the coupling is respon-

sible for all safety aspects of the combined unit.

2.3 Storage guidelines

Storage location

The product must be stored in a covered and dry location free from heat,

dirt, and vibrations.

NOTICE:

• Protect the product against humidity, heat sources, and mechanical dam-

age.

• Do not place heavy weights on the packed product.

Ambient temperature

The product must be stored at an ambient temperature from -5°C to +40°C

(23°F to 104°F).
