Installation and operating instructions Wilo-Rexa PRO 31
▪ Handling electrical machines
Strictly adhere to the responsibilities of the personnel specified by the operator. All
personnel are responsible for ensuring that the responsibilities of the personnel and the
regulations are observed!
Due to their design, centrifugal pumps have rotating parts that are easily accessible.
Depending on the operating condition, sharp edges can develop on these parts.
WARN-
ING! This can lead to cuts and limbs may be amputated and severed! Check the fol-
lowing at regular intervals:
▪ Operating voltage (+/-10 % of the rated voltage)
▪ Frequency (+/-2 % of the rated frequency)
▪ Power consumption between individual phases (max. 5 %)
▪ Voltage difference between the individual phases (max. 1 %)
▪ Max. switching frequency
▪ Minimum water submersion depending on the operating mode
▪ Inlet: no air intake
▪ Level control device/dry-running protection: Switching points
▪ Quiet/low-vibration running
▪ All gate valves open
8 Decommissioning/dismantling
8.1 Personnel qualifications ▪ Operation/control: Operating personnel must be instructed in the functioning of the
complete system.
▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials for the relevant construction site.
8.2 Operator responsibilities ▪ Locally applicable accident prevention and safety regulations of trade associations.
▪ Observe regulations for working with heavy loads and under suspended loads.
▪ Provide the necessary protective equipment and make sure that the personnel wears it.
▪ Provide adequate aeration in closed rooms.
▪ Take immediate countermeasures if there is a build-up of toxic or suffocating gases!
8.3 Decommissioning
The pump is deactivated during decommissioning, but remains installed. This ensures
that the pump is always ready for operation.
‡
To protect the pump from frost and ice, always immerse the pump completely in
the fluid.
‡
The temperature of the fluid must always be above +3 °C (+37 °F).
1. Switch off the pump at the operating point.
2. Secure the operating point against being switched on again by unauthorised per-
sons (e.g. lock main switch).
▶ The pump is out of operation and can now be dismantled.
If the pump remains installed after decommissioning, observe the following:
▪ Ensure that the prerequisites for decommissioning are maintained for the complete
period of decommissioning. If these prerequisites cannot be guaranteed, dismantle the
pump after decommissioning!
▪ For an extended period of decommissioning, carry out a 5-minute function test at reg-
ular intervals (monthly to quarterly). CAUTION! A function test may only be carried
out under the applicable operating conditions. A dry run is not permitted! Non-com-
pliance can result in irreparable damage!
8.4 Removal
DANGER
Danger due to fluids hazardous to health!
If the pump is used in fluids hazardous to health, decontaminate the pump after dis-
mantling and before carrying out any other work! There is a risk of fatal injury! Ob-
serve the specifications in the work regulations! The operator must make sure that
the personnel have received and read the work regulations!
