4.1 General safety instructions Warning Before starting any work on mixers or flowmakers, make sure that the fuses have been removed or the mains switch has been switched off. It must be ensured that the power supply cannot be accidentally switched on. Warning These safety instructions as well as the instructions in each individual section must be followed when transporting, storing, handling and operating the mixer or flowmaker.
Warning Make sure that the mixer or flowmaker cannot roll or fall over. Warning Before attempting to lift or otherwise handle the individual components of the mixer or flowmaker, observe any local regulations that set limits for the weight of the components to be lifted manually by individuals, i.e. handled without the use of lifting equipment. All lifting equipment must be rated for the purpose and checked for damage before any attempts to lift the components are made.
6.2.1 Torques All nuts and screws used for the installation must be made of stainless steel. Use grease (Alu-paste) together with a spring washer or lock nut; otherwise, use Loctite or a similar product for lubrication and locking. All stainless-steel nuts and screws should be tightened to the following torques: Screws F-class 70 [Nm] Screws F-class 80 [Nm] M6 8.8 11.8 M8 21.4 28.7 M10 44 58 M12 74 100 M16 183 245 M20 370 494 When mounting the hub/propeller, use lock washer (pos.

Slowly lower the flowmaker into the tank and down to position on the depth blocker. 20. Mount the cable sock (pos. 18) to the top fixation bracket using the shackle, and pull the motor cable through it, to the desired position. See fig. 25. The power supply cable should be slightly tightened.
7.1 Motor protection Electrical connections must be carried out by a qualified electrician in accordance with local regulations. All national and local regulations relating to safety and accident prevention must be observed. The mixers and flowmakers are provided with the following types of motor protection: Standard mixers incorporate three bimetallic PTO thermal switches. See fig. 29. Explosion-proof mixers and all flowmakers incorporate three PTC sensors (temperature sensors) according to DIN 44081.
To adjust the sensitivity of the ALR-20/A-Ex relay, proceed as follows: 1. Turn the adjusting screw on the relay a until the indicator light b lights up. 2. Turn the adjusting screw in the opposite direction until the indicator light goes out. 3. Continue to turn the adjusting screw 60 ° (same direction as under point 2). 2 10 4 A1 A2 Netz Warning Explosion-proof mixers and flowmakers must be connected to the Grundfos relay, type ALR-20/A-Ex. Classification: II (2)G [Ex ib] IIC. Part number: 96489569.
U1 V1 W1 W2 U2 V2 The motor must be protected against overload via a thermal delay relay according to local regulations. The relay must be adjusted to the rated current stated on the nameplate. In the case of star-delta starting, the adjustable value is to be IN x 0.58. Incorporate electro-thermal all-pole triggers in all six mains conductors (U1, V 1, W1 and U2, V2, W2). PTC LS PE English (GB) 7.3 Overload relays 7.4 Starting method 7.4.1 Mixers TM02 4932 2002 Continuous operation Motors up to 2.
7.8 Frequency converter operation When the electrical connections have been carried out, check that the mixer or flowmaker propeller is rotating in the correct direction. When viewed from the motor, the propeller should rotate clockwise. An arrow on the motor housing shows the correct direction of rotation. If the mixer or flowmaker propeller rotates in the wrong direction, interchange two phases of the mains supply (L1, L2, L3). AMD.15.45B.710.Ex.5.0A.A, AMD.35.45B.705.Ex.5.1A.A, AMD.20.45.700.Ex.5.0A.
9. Service Check the oil level in the gearbox/shaft seal housing before starting up the mixer or flowmaker. The oil level must cover between 50 and 75 % of the gearbox/shaft seal housing. Warning As pressure may have built up in the oil chamber, slacken the oil screw slowly. Do not remove the screw until the pressure has been fully relieved. If required, fill oil into the gearbox/shaft seal housing through the oil filling hole (pos. 2). See fig. 32. For oil quality and quantity, see section 9.4.
9.3 Service chart English (GB) Electric motor Power supply cable Shaft seal housing Gearbox Type Service instructions Lubrication Inspection All Keep the motor housing clean (otherwise cooling is affected). The motor housing must only be dismantled by Grundfos. The roller bearings are maintenance-free. They should be replaced if they become noisy. For motors filled with dielectric oil, oil level check and oil change are not required.
9.5 Oil change 9.4.1 Oil quality, gearbox and shaft seal housing Gear oil designation for mixers (AMD, AMG) is according to DIN 51502: ISO VG 68. Gear oil designation for flowmakers (AFG) is according to ISO VG 220. AMD To change the oil in the shaft seal housing, proceed as follows: 1. Remove propeller. 2. Remove oil filling and oil drain screws. 3. Drain oil into a glass and leave it there for approx. 10 minutes, and check if it contains water. If the oil contains water, replace the shaft seal. 9.4.
10. Fault finding English (GB) Warning Before starting any work on mixers or flowmakers, make sure that the fuses have been removed or the mains switch has been switched off. It must be ensured that the power supply cannot be accidentally switched on. All rotating parts must have stopped moving. Warning All regulations applying to mixers or flowmakers installed in potentially explosive environments must be observed. Make sure that no work is carried out in potentially explosive environment.
Cause 4. a) Internal parts are worn. Contact Grundfos. b) Propeller blades are dirty or damaged. Clean the blades, and inspect for any wear. In case the propeller blades are worn or damaged, contact Grundfos. c) Faulty motor or gearbox roller bearings. Contact Grundfos. d) Oscillations caused by the installation (resonance). Check installation design. a) Wrong voltage supply or supply failure. Call an electrician. 5. Mixer or flowmaker runs unevenly and is noisy.
