Following Installation; Electrical Connection; Personnel Requisition; Requirements - Wilo Stratos MAXO Série Notice De Montage Et De Mise En Service

NOTICE
The thermal insulation shells included in the scope of
delivery are exclusively permitted in heating and do-
mestic hot water circulation applications with fluid
temperatures > 20 °C!
Insulation of the pump in cooling/air-conditioning systems
Single pumps can be insulated for use in cooling and air condition-
ing applications using Wilo cold water insulation shells (Wilo-
ClimaForm) or any other commercially available, diffusion-proof in-
sulation materials.
There are no prefabricated cold water insulation shells for twin-
head pumps. For this purpose, use commercially available, diffu-
sion-proof insulation materials provided by the customer.
CAUTION
Electrical defect!
Condensate that accumulates in the motor can cause an elec-
trical defect.
ƒ
Insulate pump housing only up to the separating gap to the mo-
tor!
ƒ
Keep the condensate drain grooves unobstructed to ensure that
condensate that develops in the motor can drain off without
problems!

DANGER
Risk of fatal electrical shock!
• Immediate risk of fatal injury if live components are
touched!
• Failure to install safety devices (e.g. module cover
of control module) can cause electrical shock, poten-
tially resulting in life-threatening injuries!
• Even if the LED is not illuminated, voltage may be
present inside the control module!
• If setting and operating elements are improperly re-
moved from the control module, there is a danger of
electric shock if interior electrical components are
touched!
• Applying an incorrect voltage to SELV lines will re-
sult in incorrect voltage in all pumps and on-site
building automation devices that are connected to
SELV lines.
