NEVERCOLD™
NEVERCOLD™ pumps are specifically designed to prevent solid particles from
entering the bearing / rotor chamber of the cartridge. However, in systems heavily
contaminated by dirt, construction debris, etc., particles may enter the chamber on
initial filling of the system and on rare occasions cause rotor blockage.
The NEVERCOLD™
NEVERCOLD™ pump is designed to permit cleaning the interior of the cartridge
and de-blocking. To do so, separate the two parts (refer to #6 under “Replacing
Cartridge Assembly”) by grabbing the impeller and cartridge sleeve with opposite
hands and pulling apart. Clean (rinse) the two parts and re-assemble. Follow the
procedure under “Replacing Cartridge Assembly.” It is also recommended to flush
the system.
