1GA/2GA Installation, Operation and Maintenance Manual 11
V. Installation
Handling Equipment
Lifting equipment is required for handling the pump.
Stay clear of suspended loads.
Always lift the pump by its lifting handle, never by the motor cable or the hose.
The minimum height between the lifting hook and the floor shall be sufficient to lift the
pump out of the sump.
The lifting equipment shall be able to hoist the pump straight up and down in the sump,
preferable without the need for resetting the lifting hook.
Oversize lifting equipment could cause damage if the pump should stick when being lifted.
Make sure that the lifting equipment is securely anchored.
General Recommendations
To ensure proper installation, please see the dimensions on the dimensional drawing in the
Parts List.
NOTE: The end of the cable must not be submerged. It must be above flood level, as water
may penetrate through the cable into the junction box or the motor.
Check that the lifting handle and chain are in good condition.
For automatic operation of the pump (level control), it is recommended that the level
regulators be used at low voltage. The data sheet delivered with the regulators gives the
permissible voltage. Local rules may specify otherwise.
Clean out all debris from the sump before the pump is lowered down and the station is
started.
Special rules apply to installation in explosive atmosphere. Intrinsically safe
circuits are normally required (Ex I) for the automatic level control system by
level regulators.
Safety Precautions
In order to minimize the risk of accidents in connection with the service and installation
work, the following rules should be followed:
1. Never work alone. Use a lifting harness, safety line and a respirator as required. Do not
ignore the risk of drowning!
2. Make sure there are no poisonous gases within the work area.
3. Check the explosion risk before welding if using electric hand tools.
4. Do not ignore health hazards. Observe strict cleanliness.
5. Bear in mind the risk of electrical accidents.
6. Make sure that the lifting equipment is in good condition.
