Operation guide
Installation, Operation and Maintenance Manual for PAHT 256-308 pumps
When lifting the pump unit, one sling must be
attached to the electric motor and one sling
around the pump.
Only some motors and pumps have specific
lifting eyes.
Do not use connections/nozzles for lifting!
Do not use only one sling!
Make sure that the unit/load is balanced before
lifting. The centre of the mass varies from pump/
pump unit size to pump/pump unit.
How to mount the pump and the electric motor
correctly, see appendix 1, Data sheet or appendix
2, Instruction.
Incorrect lifting can result in personal injury
and/or damage to the pump unit, see appendix
2, Instruction.
Once the lifting is done the lifting eye must
be removed from the pump.
4.5 Return to supplier
Please see maintenance chapter 7.
4.6 Storage
Each pump is tested before shipment, and will
therefore contain water. For storage temperature
and frost protection see appendix 2, Instruction.
The pumps are NOT delivered frost protected
from the factory.
Wrong lifting:
Pumps which have a weight above 20 kilos (see
appendix 1, Data sheet) must be handled by
using lifting eyes and slings.
When the pump is mounted together with an
electric motor, the pump unit always weigh more
than 20 kilos and must be handled by using
slings around the pump unit.
See below examples of where to/not to attach
the lifting slings on the pump unit:
