7.1.3 Insulation of the pump in heating systems
Thermal insulation shells (optional accessories) are only permissible in heating applic-
ations with fluid temperatures 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:
ƒ
WARNING

Hot surface!

The entire pump can become very hot. When retrofitting the insulation during
normal operation there is a risk of burns!
ƒ
CAUTION
Insufficient heat dissipation and condensate may damage the
control module and glandless motor!

7.1.4 Insulation of the pump in cooling systems
The Para MAXO-G and Para MAXO-R series are suitable for use in air-conditioning
systems, cooling systems, geothermal systems and similar systems with fluid temper-
atures down to below 0 °C. Condensate can form on fluid-carrying parts, e.g. pipes
and pump housing.

Installation and operating instructions Wilo-Para MAXO/-G/-R/-Z
Note the direction arrow on the pump housing.
Install with glandless motor (Fig. I, Item 2) horizontal, without mechanical ten-
sion.
Place gaskets in the screwed connections.
Screw on threaded pipe unions.
Use an open-end wrench to secure the pump against twisting and screw tightly
to piping.
Fit the two half-shells of the thermal insulation and push them together so that
the guide pins engage in the opposing holes.
Allow the pump to cool down before commencing any work.
Do not thermally insulate the glandless motor.
Ensure all condensate drain openings (Fig. I, Item 3) are kept free.
A diffusion-proof insulation must be provided by the customer for application in
such systems (e.g. Wilo Cooling Shell).
