St Alternative

● Attach min. 2, better 4 eye-bolts to the upper flange of the agitator lantern

● Attach the lifting gear to the eye-bolts and to a hook with slip-off protection

Nd Alternative

● Create loops on both ends of a long rope/belt sling from non-metallic material and attach them underneath the upper flange of the agitator lantern

● Tighten the loops and put the sling into a hook with slip-off protection Instead of one long sling two identical short slings can be used

4.2 Storage (without coated surfaces) Short-term Storage Short-term storage means storage for up to two months at normal climate conditions. At extreme climatic conditions: → "Long-term Storage".

● Keep shafts on wooden beams and protect from rolling ● Protect from dust and humidity (cover) ● Store vibration-free ● Avoid contact between stainless steel parts and carbon steel or between other different metallical parts (e.g. titanium, tantalum etc.)

	WARNING
Prevent upright agitator drives from turning over

● Outdoor storage only on wooden bases, never right on the ground

Long-term Storage

Long-term storage means storage for more than

two months or at extreme climate conditions.

● All measures of "Short-term Storage" additionally:

● When possible in closed buildings only

● Discuss storage conditions with FLUID-Service

● Repair damage to the exterior painting

● Check corrosion protection on machined surfaces, repair as necessary; repeat every 6 months

Motor (when in scope of supply):

● See instructions by the motor manufacturer
(→ Chapter 9)

Gearbox (when in scope of supply): ● See instructions by the gearbox manufacturer (→ Chapter 9) If the gearbox instructions do not deal with long-term storage the following will apply: ● Turn geared motors every 6 months so that all internal parts will be covered with a new oil layer Flat gears and large gears are treated with a preservative. Provided that all ports are closed and the gearbox is stored in a dry place at moderate temperatures the conservation will last 24 months. Shrink-wrapping in an vapour-tight plastic sheet will extend the storage time to 48 months. Mechanical seal with buffer fluid (when in scope of supply): ● See the instructions by the seal manufacturer (→ chapter 9) In case the seal instructions do not deal with long-term storage: ● Before storage drain the buffer fluid Outdoor Long-term Storage EKATO generally recommends to avoid outdoor long-term storage. When it cannot be avoided: ● Follow instructions of non-FLUID components (→ chapter 9) ● Protect the assemblies in airtight sheeting together with drying agent ("Silicagel") and pack in original casks ● Cover the crates Every 3 to 6 months: ● Replace drying agent ● Clean unpainted or corrodible surfaces and apply new corrosion protection Start-up after Long-term Storage ● Follow the instructions for non-EKATO components (Motor; Gear Unit; Mechanical seal etc. → chapter 9)

4.3.0 Additional Mounting Instruction For the assembly of the agitator, the different agitator parts are stamped with their corresponding serial No. Note: To identify the required mounting orientation the rotating agitator parts could be provided with additional markings. ● Assemble the flange connections and impeller hubs depending on the stamped serial No. and if applicable according the additional marking.

Assembly

(Flange coupling with single nuts and locking plates, without rubber coating)

Required Tools

	WARNING
Works on hanging loads Before work study lifting procedures, check weights (→ chapter 1) and select suitable lifting gear

- 2 cranes (alternatively 1 crane and another device for the lifting of the agitator shaft) - 2 lifting eyes, fitting the holes in the agitator shaft flange - Ropes or belts - 1 shackle - 2 clean wooden beams (alternatively rubber plated U- or

-beams), with holes and fixing screws - other wooden beams to support the erected agitator - generals tools

Preparatory Works/Checks ● Check that the nozzle seal face complies with the requirements (roughness) and is free from damage

Max.

Only for vertically mounted agitators: ♦ Check that the flange surface’s deviation to the horizontal does not exceed. 0.2°. ♦ If necessary rearrange the vessel
