5. Installation and initial commissioning
5.1. General
To avoid damage to the lifting unit during installation and
operation, the following points must be observed:
• The installation work must be performed by qualified
personnel, in compliance with safety regulations.
• The pump must be inspected for damage prior to in-
stallation.
• For level controls, pay attention to the minimum wa-
ter coverage.
• Air bubbles in the volute and pipework must be avoid-
ed (by suitable ventilation devices or a slight incline
of the pump).
• Protect the pump from frost.
• The lifting device must have a maximum load capaci-
ty which is greater than the weight of the pump with
attachments and cable.
• The power lines of the pump must be laid in such a
way, that a safe operation and easy assembly/disas-
sembly is ensured.
• The power lines must be fixed properly in the operat-
ing room to prevent the cable from hanging loosely.
Depending on the cable length and weight, a cable
holder must be attached every 2-3 m.
• The foundation/structure must have sufficient
strength for secure and functionally correct fastening
of the pump. The operator is responsible for this.
• Verify low level lockout is functioning.
• Use baffles for the inlet. This prevents air entry into
the pumping medium, which can lead to unfavorable
operating conditions and result in increased wear.
• Do not install more than one check valve into any pip-
ing system or problems will occur.
No.

External Seal Probe Installation Procedure
If provided, Mechanical Seal Leak Detection probe has
been shipped loose to protect from shipping damage.
Please follow this procedure to install the probe.
1)
Lay pump on its side with the plug on the seal
chamber facing upwards as indicated.
2)
Unscrew the plug with the proper wrench, taking
care not to damage the sealing surface.
3)
Verify that seal chamber oil level is within ¼”
of the indicated value. Measurement is from oil
level to the top of hole. See IOM Manual for seal
chamber oil volume, if required.
4)
Remove the new sealing gasket from package and
install it onto the seal probe plug.
5)
Install the seal probe with gasket into the opening,
taking care not to damage the cable. Then tighten
the seal probe with the proper wrench until snug.
Do not overtighten. Once tight, verify the seal
gasket is properly seated and the cable is not
pinched or twisted.
NOTE: At installation of the seal probe be careful
not to bind the seal probe cord as it is being
installed into the pump.
6)
Lift pump into a vertical position and inspect for
any leaks.
7)
Secure seal probe cable to pump body and power
cable with tyraps before installing pump.
