9.2 Storing the product

Leave the cable end protectors and control cables on the
power until making the electrical connection. Whether
insulated or not, the free cable end must never be
exposed to moisture. Non-compliance with this may cause
damage to the motor.
For long periods of storage, six months or longer, the pump must be
protected against moisture and heat.
If the pump is being stored for more than two months, turn
the impeller by hand at least every two months to prevent
the seal faces of the lower mechanical shaft seal from
seizing up.
Avoiding this may cause damage to the shaft seal when
the pump is started.
If the impeller cannot be turned by hand, contact an
authorized service workshop.
For dry-installed pumps, installation types D and H, make
sure the cooling jacket is empty before storing the pump.
After a long period of storage, six months or longer, inspect the
pump before putting it into operation. Make sure that the impeller
can rotate freely. Pay attention to the condition of the shaft seals, O-
rings and the cable entries.
