Receipt, storage and handling
1.2.1
Receipt, storage
Check the consignement for damage immediately on
arrival. In case of damage, clearly mark upon the carrier’s
paperwork (with a brief description of the damage) that the
goods have been received in a damaged condition. Notify
your Johnson Pump distributor.
Always state the pump model and serial number when
asking for assistance. This information can be obtained
from the name plate which is located on the end cover (see
section 1.5).
Should the name plate be unreadable or missing, the serial
number is also stamped on the end cover and the rotor case
(see section 1.5).
If the pump is not installed immediately, it must be stored
in a suitable environment.
1.2.2
Handling
Caution must be taken when lifting the pump. All parts with a weight of more than 20 kg
must be lifted using lifting slings and suitable lifting devices.
Lifting eye fitted to pump must only be used to lift the pump, not the pump with drive
and/or baseplate.
If the pump is baseplate mounted, the baseplate must be used for all lifting purposes.
When using slings, they must be safely and securely attached (1.3 Safety instructions).
