Always disconnect the power supply while servicing the Agitator.

Ensure correct rotation direction of propeller before startup and after any maintains there might have impact on

the direction.

Never service the agitator or tank with product or cleaning liquid in the tank.

2.4.4 Transportation:

Always transport the Agitator in original packaging.

Always support the shaft adequately, to protect shaft and bearings.

Never expose the Agitator to undue vibrations or shocks.

Control for oil leakage on gears with vent screw.

Ensure correct rotation direction of impeller before startup and after any maintains there might have impact on the

direction.

3 Installation

The instruction manual is part of delivery. Study the instructions carefully.

The Agitator is for permanent fastening.

Make sure the motor corresponds to the environment.

Check the direction of rotation before operation.

3.1 Unpacking/delivery

Always use lifting equipment when handling the Agitator.

Alfa Laval cannot be responsible for incorrect unpacking.

Step 1

3.1.1 Inspect the delivery for visible transportation damage (crates and packaging) - all issues should be reported to carrier.

Step 2

3.1.2 Check that deliveries are according to delivery notes.

Complete Agitators can be delivered in more than one shipment.

Agitators can be delivered as one of the following:

1. Agitator parts and instruction manual required for tank builder to install shafts and propellers.

2. Agitator parts and instruction manual required for tank builder to install drive unit (gear motor) and sealing system.

3. As 1) and 2) in one shipment.

Step 3

3.1.3 Inspect Agitator parts for visible transport damage.

Step 4

Do NOT use eye bolts on gear motor to lift the Agitator. They are only for gear motor removal.

Step 5

3.1.5 During lifting:

- Always support the shaft adequately to protect shaft and bearings.

- Be carefully not to damage shaft-end with treads.

- Never expose the Agitator to undue vibrations or shocks.

- Control for oil leakage on gears – leave vent plug in gear until gear is installed and in correct position.

3.3 Installation (with cutting/machining and welding required)

3.3.1 Requirement for installation

This work should be carried out by at least two persons and for safety reasons a platform or a scaffold should be

established around the tank top.

During installation ensure to use sufficient lightning.

The tank top must be horizontally during installation – if that is not the case, a laser must be used to ensure that the

right position for the “Bottom Console” can be found.

Ensure that the tank does not contain neither dangerous liquid nor gasses and that good ventilation is established.

Always have safety elements removed by authorized personnel.

Never cover or remove nameplates.

Always use lifting equipment when handling heavy parts of the Agitator.

Never connect to power during installation.

Always have the Agitator connected to power supply by authorized personnel.

Note: Alfa Laval highly recommends installing motor protection guard to the Agitator.

All position numbers and item numbers refer to the drawings show and specified in 7 Parts list / Service kits

3 Installation

The instruction manual is part of delivery. Study the instructions carefully.

The Agitator is for permanent fastening.

Make sure the motor corresponds to the environment.

Check the direction of rotation before operation.

Step 1

3.3.2

See illustration in 7.5.1 page 38.

A. The three “Adjustable Leg For Bottom Console” pos. 70 are fastened to the “Bottom Console for Agitator” pos. 74 using

the three “Screw” pos. 77.

B. The assembled “Bottom Console” from a)

“Guide spindle for bearing” pos. 69

“Tool – Bushing” pos. 83,

“Tool – Back stop” pos. 85,

“Screw” pos. 91,

“Propeller” pos. 73,

“Agitator Shaft” pos. 71 (if delivered),

“Propeller” pos. 72 (if delivered),

“Agitator Shaft” pos. 75,

are lowered into the tank and assembled. In some cases all the parts can be assembled outside the tank and lowered into

the tank assembled. All threads must be greased to ensure not to damage the threads.

C. According to the order specific drawing "Agitator with Tank" that comes with the manual (not in the manual) the correct

Agitator position is selected (0/125/175 mm off center) which specify which position of holes to be used (data in this

manual are not to be used – find order specific drawing).

Example of an order specific drawing "Order specific "Tank With Agitator" drawing, example" are to be found in 8.2, page 42.

D. Mount the “Tool Guide Plate” pos. 80 on the “Tank mounting flange” pos. 99 letting the shaft pos. 75 entering the correct

hole in pos. 80. The “Tool Guide Plate” must be fastened to the tank top using two diagonally located holes in the tank top.

E. Mount the “Tool – Top Guide” pos. 82 to the “Tool Guide Plate” pos. 80 using the four “Screw” pos. 88.

F. Mount the “Tool – Top Guide” pos. 81 into the “Tool – Top Guide” pos. 82.

G. Rotate / orientate pos. 82 enabling the “Screw” pos. 90 to be used to fasten the shaft in vertical direction during adjustment

of the “Bottom Console” pos. 74.

3 Installation

The instruction manual is part of delivery. Study the instructions carefully.

The Agitator is for permanent fastening.

Make sure the motor corresponds to the environment.

Check the direction of rotation before operation.

Step 2

3.3.3 See illustration in 7.5.1 page 38.

A. If the tank top is horizontally within 0,5° the gravity can be used

as guideline for position of the “Bottom Console” – if it is not

possible to adjust the tank top to horizontally position (within

the tolerance) a laser pointer must be used to ensure that the

right position for the “Bottom Console” is found.

B. The Agitator is lifted to the correct position as shown on the

order specific drawing “Tank with Agitator” that comes with

the manual (not in the manual).

Example of an order specific drawing "Order specific "Tank

With Agitator" drawing, example" are to be found in 8.2, page

42. The “Screw” pos. 90 is tightened (not more than sufficient)

to fasten the shafts in vertical position.

C. When the agitator shaft is in correct position the three

“Adjustable Leg For Bottom Console” pos. 70 are

adjusted/rotated facing the tank bottom and the three “Screws”

pos. 77 are fastened. If the legs on “Bottom Console for

Agitator”pos. 74aretoolongtheyarecuttotherequired

length.

D. Tag weld the three “Adjustable Leg For Bottom Console” pos.

70 to the tank bottom using TIG welding.

E. Untighten the “Screw” pos. 90 ensure that the shaft can rotate

freely.

F. Tighten the screw again.

G. Remove one “Screw” pos. 77 and fill the thread hole with

welding, continue one by one with the two other screws.

H. Remove the “Screw” and pos. 90.

I. Verify that the shaft can rotate freely.

J. Grind the welded seams to the required finish.
