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, preferably 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 dimen-
sions 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 regu-
lators 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.
Safety precautions
In order to minimize the risk of accidents in connection
with the service and installation work, the following
rules should be followed:
11. Never work alone. Use a lifting harness, safety
line and a respirator as required. Do not ignore
the risk of drowning.
12. Make sure there are no poisonous gases within
the work area.
13. Check the explosion risk before welding or using
electric hand tools.
14. Do not ignore health hazards. Observe strict
cleanliness.
15. Bear in mind the risk of electrical accidents.
16. Make sure that the lifting equipment is in good
condition.
17. Provide a suitable barrier around the work area,
e.g a guard rail.
18. Make sure you have a clear path of retreat!
19. Use safety helmet, safety goggles and protective
shoes.
10. All personnel who work with sewage systems
must be vaccinated against diseases to which
they may be exposed.
11. A first-aid kit must be close at hand.
12. Note that special rules apply to installation in
explosive athmosphere.
Follow all other health and safety rules and local
codes and ordinances.
NOTE for Ex version page 3.
— Minimum stop level should be
according to the dimensional
drawing.
— The pump must never run dry.
