5. Installation and Start-Up
5.1. General
•
The following points must be noted to prevent dam-
ages in the pump during installation and commission-
ing:
•
The pump must be checked for possible damages pri-
or to installation.
•
The minimum submersion in water must be consid-
ered for level control.
•
Air pockets in the pump casing and in pipes must be
avoided (by means of appropriate venting facilities or
slight tilting of the pump).
•
Protect the pump from frost.
•
The power lines of the pump must run in a way that
hazard-free operation and easy assembly/disassem-
bly is possible.
5.2. Installation
Danger of falls!
When mounting the pump and its accessories work
is carried out directly at the edge of the basin! Care-
lessness or wrong footwear can lead to falls. There
is danger to life! Take all safety measures to prevent
this.
The pump can be used with or without a carrying frame.
Before the pump can be removed from the carrying frame,
the fixing strap must first be loosened. When the pump
is operated with the carrying frame, it should be secured
with the fixing strap again.
Connect the accompanying hose to the pressure connec-
tion of the pump. Place the „Flut-Set" or the pump on
a firm, level surface. If the supporting surface is muddy,
stony or the like, lay the pump under the carrying frame to
prevent it sinking.
When using the hose it must be ensured that this is laid
our without bends. When using accessories, such as a
quick coupling, or similar, it has to be ensured that these
are sealed with teflon tape, since leakage reduces the
conveyor performance of the pump.
Automatic float switch
Due to the direct connection of the float switch in the
pump, the pump switches on automatically when it is
triggered manually! So make sure that the pump is not
connected when you work on it. When the water level
rises to the switch-on point, the rising float switches the
pump on automatically. If the water level has dropped to
the switch-off point due to pumping out, the float swit-
ches the pump off.
5.3. Start-Up
This chapter contains all important instructions for oper-
ating personnel for safe commissioning and operation of
the machinery
The following points must be taken into account to avoid
personal and material damage when troubleshooting ma-
chinery failures:
The commissioning of the machinery must only be
carried out by qualified and trained personnel in com-
pliance with the safety regulations.
•
All personnel that is working on the machinery must
have received, read and understood the operating in-
structions.
•
This machinery is only suitable for the use under the
indicated operating conditions.
Never let the pump run dry for longer periods of time
(risk of overheating).
5.4. Electrical system
The respective local and VDE regulations must be com-
plied with when choosing and installing the electrical
leads as well as connecting the motor. The motor must be
protected by a motor protection switch.
Have the motor connected in accordance with the „Wiring
connection" data sheet. Pay attention to the direction of
rotation. If the direction of rotation is incorrect, the ma-
chine will not perform as specified, and under certain cir-
cumstances, can become damaged.
Electric shock hazard!
Faulty dealing with current may jeopardize your life!
All pumps with free cable ends must be connected by
a qualified electrician.
5.5. Switch-on types
Switch-on types with plug
Insert the plug into the socket provided for.
5.5.1. After switching on
The rated current is surpassed quickly during the start-
up process. After termination of this process the work
current should not exceed the rated current. If the mo-
tor does not start immediately after switch-on, it must be
switched off immediately.
Before further switch-on the switch pauses according to
the technical data must be complied with. In the event
of a further interference the machine must be switched
off immediately. A further switch-on process may only be
started after recovery of the fault.
The following points should be checked:
•
Switching frequency and pauses (see technical data)
•
Minimum submersion in water, level control, protec-
tion against dry run
•
Smooth run Check for leakages, if appropriate take
the necessary steps according the chapter 'mainte-
nance'
