WARNING
Sharp edges on the impeller!
Sharp edges can form on the impeller. There is a risk of limbs being
severed!
• Wear safety gloves to protect against cuts!
NOTICE
For all installation work, use the forked spacer to set the correct impeller
position in the pump housing!
Forked spacer for setting work
CAUTION
Risk of property damage!
Improper operation can damage the pump or motor. Operation with
closed shut-off devices is critical and generally dangerous with hot li-
quids. Do not run the pump for longer than 1 min without flow. Dry run-
ning causes a build-up of energy in the pump, which can damage the
shaft, impeller, and mechanical seal.
• Only run the pump with fluid.
• Do not operate the pump with the shut-off device in the suction line
closed.
• Do not operate the pump for a longer period of time with the shut-off
device in the discharge line closed. This can cause the fluid to over-
heat.
The pump must run quietly and vibration-free at all times.
• Check the static gaskets and the shaft seal regularly for leakages.
• For pumps with mechanical seals, there is little to no visible leakage during operation. If
a gasket is leaking significantly, this is a sign that the gasket surfaces are worn. The gas-
ket must be replaced. The service life of a mechanical seal greatly depends on the oper-
ating conditions (temperature, pressure, fluid properties).
• Wilo recommends briefly putting the standby pumps into operation at least once a week
to ensure they are always ready for operation.
• Check the air supply to the motor housing at regular intervals. Dirt impairs the cooling of
the motor and electronic module. If necessary, remove dirt and restore unrestricted air
supply.
WARNING
Risk of injury and damage to property!
• Dispose off the pump contents and rinsing fluid by taking the legal
regulations into account.
• Always wear protective clothing, protective gloves and protective
goggles when working.
