Insulation of the pump in heating systems and domestic hot water circulation ap-
plications (only single pump)
WARNING
Hot surface!
The entire pump can become very hot. When retrofitting the insulation during nor-
mal operation there is a risk of burns!
Place both the half shells of heat insulation around the pump housing before commis-
sioning 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 per-
mitted in heating and domestic hot water circulation applications with fluid temper-
atures > 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 pur-
pose, use commercially available, diffusion-proof insulation materials provided by the
customer.
