7.1.3 Insulation of the pump in heating systems

Thermal insulation shells (optional accessories) are only permissible in heating applications with fluid tem-
peratures from +20 °C, since these thermal insulation shells are not diffusion-proof when enclosing the
pump housing.
Fix thermal insulation shell before commissioning the pump:
• Fit the two half-shells of the thermal insulation and push them together so that the guide pins engage in
the opposing holes.
WARNING
Risk of burns from hot surfaces!
The entire pump can become very hot. When retrofitting the insulation during ongoing op-
eration, there is a risk of burns!
• Allow the pump to cool down before commencing any work.
