In areas where the staff has to intervene, remember that when the level of the sound pressure is:
below 70 dBA: it is not necessary to take special precautions.
above 70 dBA: people working continuously in the machine room must be supplied with protective devices against noise.
below 85 dBA: no particular measures need to be taken for casual visitors staying in the room during a limited period.
above 85 dBA: the room must be considered as a dangerous area because of the noise and a warning sign must be fixed at each entry warning the people coming into the room, even for a short period, that they must wear hearing protection.
above 105 dBA: special hearing protection adapted to this noise level and to the spectral noise components must be installed and a warning sign to this effect erected at each entry. The staff in the room must wear ear protection.
Make sure that the noise, which travels through the walls and windows, does not generate too high noise levels in the machine room's surroundings.
2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be checked against the delivery and shipping documents for its completeness and that there has been no damage in transportation.
Any shortage and or damage must be reported immediately to Flowserve and received in writing within one month of receipt of the equipment. Later claims cannot be accepted.
Check any crate, boxes and wrappings for any accessories or spare parts that may be packed separately with the equipment or attached to sidewalls of the box or equipment.
Each product has a unique serial number. Check that this number corresponds with that advised and always quote this number in correspondence as well as when ordering spare parts or further accessories.
2.2 Handling
2.2.1General instructions concerning handling Boxes, crates, pallets or cartons may be unloaded using forklift vehicles or slings dependent on their size and construction. See 2.3.1 for positioning of slings.
To lift heavy pieces above 25 kg (55 lb), use a winch adapted to the mass and in accordance with the current local regulations.
To lift machines or pieces with one or several suspension rings, only use hooks and chains in compliance with the local regulations concerning safety.
Never put cables, chains or ropes directly on or in the suspension rings. Cables, chains or lifting ropes must never present excessive bending.
Never bend the lifting hooks, suspension rings, chains, etc., which should only be made to endure stresses within, calculated limits. Remember that the capacity of a lifting device decreases when the direction of the lifting force direction makes an angle with the device axis.
To increase the safety and the efficiency of the lifting device, all the lifting elements must be as perpendicular as possible. If necessary a lifting beam can be placed between the winch and the load.
When heavy pieces are lifted up, never stay or work under the load or in the area, which could be in the path of the load if it were to swing or fall away. Never leave a load hanging from a winch. The acceleration or the
A winch must be positioned in such a way that the load will be raised perpendicularly. Where possible necessary precautions must be taken to avoid the swing of the load, using for example two winches making approximately the same angle, below 30°, with the vertical.

All motors (for masses see the motor description plate) must be handled with a winch.
For masses above 25 kg (55 lb), manual handling is forbidden.
2.3 Lifting
2.3.1 Slinging of motor pumps units
Use handling means in accordance with motor pump unit mass mentioned on the CE plate. For the masses of the pumps bare end of shaft see table § 2.2.2 and nameplate.
To avoid distortion, the pump unit should be lifted as shown.
