Basically, all work on the machine is to be performed while the machine is not
in operation. The sequence for shutting the machine down described in the
Operating Instructions must be strictly observed.
Pumps or pump units handling hazardous liquids must be decontaminated.
Immediately upon completion of the work, all safety and protective equipment
must be restored and activated.
Before restarting the machine, all points contained in chapter "Initial Start-up"
must be observed.

3. Transportation and Intermediate Storage
Prolonged intermediate storage in an environment of high humidity and fluctua-
ting temperatures must be avoided. Moisture condensation may damage
windings and metal parts. Non-compliance will void any warranty.
4. Description
The plastic parts in contact with the pumping medium are mostly made of poly-
propylene PP and thus possess excellent corrosion resistance against the pool
water and the usual chemicals for treatment of the pool water.
The motor shaft also serves as the pump shaft on which the impeller is moun-
ted. The seal for the shaft is a bellows-type mechanical seal arranged on a
plastic impeller hub. This guarantees positive electrical separation between the
pool water and the electric motor. Because of the pump's closed coupled de-
sign, a minimum of space is required. The pumps are driven by single phase
motors.
