Installation and operating instructions • Wilo-Atmos GIGA-I/-D/-B • Ed.01/2023-06
WARNING
There is a risk of burns or freezing upon coming into contact
with the pump/system.
Depending on the pump and system operating conditions (fluid temper-
ature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool to room temperature!
• Always wear protective clothing, protective gloves and protective
goggles when working.
NOTICE
For all installation work, use the forked spacer to set the correct impeller
position in the pump housing!
Forked spacer for setting work
Check the air supply to the motor housing at regular intervals. Dirt impairs the cooling of
the motor. If necessary, remove dirt and restore unrestricted air supply.
DANGER
Risk of fatal injury from falling parts!
Falling pumps or individual pump components may result in life-threat-
ening injuries!
• During installation work, secure pump components against falling
down with suitable lifting gear.
DANGER
Risk of fatal electrical shock!
Check for absence of voltage and cover or cordon off adjacent live parts.
Replace all gaskets that have been removed for maintenance.
There may be a slight amount of drip leakage during the running-in period. Even during
normal operation of the pump, it is normal for there to be slight leakage with the occasional
formation of drops.
In addition, carry out a visual inspection regularly. If leakage is clearly visible, replace the
gasket.
Wilo offers a repair kit which contains the necessary parts for replacement.

WARNING
Risk of scalding!
At high fluid temperatures and system pressures, allow the pump to cool
down first and then depressurise the system.
