Filling and venting

Installation and operating instructions • Wilo-Stratos GIGA, Wilo-Stratos GIGA B • Ed.01/2023-05
CAUTION
Risk of material damage due to the formation of condensate!
When using the pump in air-conditioning or cooling applications, the
formation of condensate can cause motor damage. The motors are
equipped with condensate drainage holes, which are factory-sealed with
plastic plugs.
• Open the condensate drainage holes in the motor housing at regular
intervals and drain the condensate.
• Then reseal the condensate drainage holes with plastic plugs.
CAUTION
If the rubber plug is removed, protection class IP55 is no longer ensured!
• Electrical work: Electrical work must be performed by a quali-
fied electrician.
• Installation/dismantling work: The installation/dismantling
must be carried out by a qualified technician who is trained in
the use of the necessary tools and fixation materials.
• The product must be operated by persons who are instructed
on how the complete system functions.
CAUTION
Dry running will destroy the mechanical seal! It may cause
leakage.
• Ensure that a dry run of the pump is not possible.
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.
DANGER
Danger of personal injury and material damage due to ex-
tremely hot or extremely cold pressurised fluid!
Depending on the temperature of the fluid, when the venting device is
opened completely, extremely hot or extremely cold fluid may escape in
liquid or vapour form. Fluid may shoot out at high pressure depending on
the system pressure.
• Always exercise caution when opening the venting device.
• Protect the electronic module from any water escaping when venting.
