Installation and operating instructions Wilo-EMU KS
Installation and electrical connection
▪ The corresponding IP class must be observed when using switchgear. Install the
switchgear in an overflow-proof position and away from potentially explosive areas!
▪ Avoid air intake into the fluid, use baffles or deflector plates for the inlet. Air which has
entered the system can collect in the pipe system and lead to impermissible operating
conditions. Air pockets must be removed via ventilation systems!
After a storage period of more than 6 months, turn the impeller prior to installation.
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction port. There is danger of limbs be-
ing severed! Protective gloves must be worn to protect from cuts.
‡
The pump is not connected to the mains!
‡
Protective equipment has been put on!
1. Place the pump upright on a firm surface.
WARNING! Risk of hands being crushed. Make sure that the pump cannot fall
over or slip!
NOTICE! Do not position the pump horizontally, as otherwise oil can escape
from the motor!
2. Pumps without suction strainer: Reach into the hydraulics housing carefully from
below and slowly and turn the impeller.
Pump with suction strainer: Insert a suitable tool through the suction strainer and
turn the impeller.
WARNING
Risk of burns from hot surfaces!
Motor housing can become hot during operation. It may cause burns. Allow the
pump to cool down at ambient temperature after switching it off!
WARNING
Separation of pressure hose!
Separation or movement of the pressure hose can lead to (serious) injuries. Securely
attach the pressure hose to the outlet! Prevent buckling of the pressure hose.
For portable installation, the pump is equipped with a strainer. The strainer filters coarse
solids out of the fluid and enables secure standing if placed on a solid load bearing sur-
face. This allows the pump to be installed anywhere in the operating space/installation
location. To prevent sinking in, a hard base must be used at the installation location in
case of soft load bearing surfaces. A pressure hose or pipework is connected on the
pressure side.
