Insulation
Insulation of the pump in heating systems and domestic hot water circulation applications (only single pump)
WARNING
Hot surface!
The entire pump can become very hot. When retrofitting the insulation during normal operation there is a risk of burns!
Place both the half shells of heat insulation around the pump housing before commissioning and press together. For this purpose, pre-install the four plastic dowels (scope of delivery) in the drilled holes of one half shell.
Insulation of the pump in cooling/air-conditioning systems
NOTICE
The thermal insulation shells included in the scope of delivery are exclusively permitted in heating and domestic hot water circulation applications with fluid temperatures > 20 °C!
Single pumps can be insulated for use in cooling and air conditioning applications using Wilo cold water insulation shells (Wilo-ClimaForm) or any other commercially available, diffusion-proof insulation materials.
There are no prefabricated cold water insulation shells for double pumps. For this purpose, use commercially available, diffusion-proof insulation materials provided by the customer.
CAUTION
Electrical defect!
Condensate that accumulates in the motor can cause an electrical defect.
- Insulate pump housing only up to the separating gap to the motor!
- Keep the condensate drain grooves unobstructed to ensure that condensate that develops in the motor can drain off without problems!
