5 INSTALLATION Safety precautions Follow all health and safety rules and local codes and ordinances. For extra safety and in order to minimize the risk of accidents in connection with operation, service and installation work, the following rules should also be followed: 1. Make sure there are no poisonous gases within the work area. 2. Check the explosion risk before welding or using electric hand tools. 3. Bear in mind the risk of electrical accidents. 4. Make sure that the lifting equipment is approved and in good condition. DO NOT hold, stand on or stand within a loop of either the nylon line or motor cables during lifting or lowering. Connect the DOCK-LOCK hook onto the lifting link while the pump is standing outside the pump sump before being lowered into place. The line tension drum can be mounted in a temporary bracket or be suspended in a separate lifting hook. The tension drum line capacity is 60 m. NOTE! Use only line of 8 mm diameter. Place the drum in a position so that the guide line attains the correct angle on the correct side of the lifting device and at such a height that it is accessible for handling the drum lock pin (TD1). See Fig 1. Pull out the guide line fully from the tension drum. Insert the locking pin into one of the four holes (TD2) to lock the drum. The guide line should be adjusted to required length to fit each individual pump installation. Handling precautions Suitable lifting equipment is required for handling the pump. The lifting equipment shall be able to hoist the pump straight up and down in the sump. The minimum height between the lifting hook and the access frame/cover/floor is individual for every installation. For further information, please contact your Flygt representative. Make sure that the lifting equipment is securely anchored. The total weight of the pump is stated on the data plate for the hydraulic unit. Installation Warning! Handling Risk Risk for trapping when handling the hook.

E Mounting of guide line with or without line tension drum (for CP- and CS-installations) This instruction describes link-up of the DOCK-LOCK, the first time it is installed. Connect the DOCK-LOCK to the lifting equipment and make sure that the DOCK-LOCK opens properly without stacking in the lifting equipment. Fig 1 D 5

6 Connect the guide line end Z to the DOCK-LOCK line at B. (The other end of the guide line marked X on the adjacent figure is connected to a shackle in the line tension drum). The DOCK-LOCK lifting system is now ready for operation. Equip the station with hooks for suspension of guide line. See Fig 2. Mounting of guide wire (for PL- and LL-installations) This instruction describes link-up of the DOCK-LOCK, the first time it is installed. Connect the DOCK-LOCK hook onto the lifting link while the pump is standing outside the pump column before being lowered into place. Connect the guide wire end Z to the DOCK-LOCK line at B. The other end of the guide wire marked X should be secured.

The other end of the guide line marked X should be connected to a fixed point. D Z Fig 3. Fully winded line tension drum 6

7 Installing and re-installing pump Connect the guide line (CP, CS)/guide wire (PL, LL) to the hook and the tension drum (if used). Note! Always disengage the tension drum locking pin during lifting and lowering sequence. Lower the pump into operation position. Please note that the main lifting wire/chain will slacken when the pump is in final position. At the same time as this occurs slacken the guide line/wire by hand. Make sure that the DOCK-LOCK has disengaged from the pump top, see "Practical handling advises" how to facilitate the release moment. Raise the DOCK-LOCK out of the sump/station. Before disconnection the guide line make sure that the tension drum is locked with the locking pin. After the lifting operation is completed, disconnect the guide line then store away the DOCK-LOCK and the tension drum until further use. Where applicable, the ends of the guide line/wire should be hooked onto the storage hooks until they are used the next time (see Fig 2, page 6). NOTE. Make sure that the ends of the guide line/wire are marked with "X" and "Z". Install the cables according to "Flygt Cable Handling System". 7

8 OPERATION Safety precautions WARNING! Before starting work on the pump, make sure that the pump is isolated from the power supply and cannot be energized. NOTE! This applies to the control circuit as well. Follow all health and safety rules and local codes and ordinances. Operating sequence F A This chapter describes the operating sequence when the DOCK-LOCK lifting system has already been installed and is to be used again. Link-up with the line tension drum Mount the DOCK-LOCK lifting device onto the lifting equipment (1). Mount or position the tension drum (6). Set the tension drum in pretension position. NOTE! Use the stop pin to secure the drum. Link-up the guide line end "X" (see Fig. 2, page 6) to the tension drum (6). Connect the guide line end "Z" to the DOCK-LOCK line (3), at shackle B. The DOCK-LOCK system is now ready to collect the pump. Warning! Handling Risk Risk for trapping when connecting the line to hook and tension drum! Note! Do not release the tension of the cables before the DOCK-LOCK hook has entered the lifting eye of the pump. 6 F 5 E D 1 2 A 3 B E D 4 C C B Z 1. Lifting equipment 2. DOCK-LOCK lifting device 3.

10 Retrieval and Lifting Gradually lower the DOCK-LOCK lifting device towards the pump. Make sure that the guide line is tense and not obstructed. When the hook docks with the pump top the guide line should be given an extra pull by hand to engage the hook. Lift the pump approx. 300 mm, then release the cable suspension. Recommendation: Mark the line at the docking level to make connection easier! Lift the pump out of its place. WARNING! Keep out from under suspended loads. Warning! Handling Risk Use gloves and face shield to avoid contamination and frictional damage when manually operating the line. Before removing the line from the pump top/hook make sure that the tension drum is locked with the attached locking pin. Warning! Whiplash Risk Always use tension drum locking pin to avoid line whiplash during installation and link-up. NOTE! Before starting service on the pump, make sure that the motor has cooled down sufficiently to carry out the service work. Warning! Always lift the pump by its lifting link, never by the motor cable or other parts. 10

11 Searching (fishing) sequence The DOCK-LOCK lifting device can also be used for searching (fishing) a pump when the lifting connecting line is missing. Note! Applicable only when the lifting link of the pump is visible. Mount the DOCK-LOCK lifting device onto the lifting equipment. Adjust the DOCK-LOCK hook to "fishing" position. Connect a line to the guide eye E on the DOCK- LOCK device. Lower the lifting hook into the station to the level of the searched pump top. Then pull the line so that the hook enters the pump's lifting link. By lifting carefully, the DOCK-LOCK will be automatically locked into position and the pump can be lifted. The pump and the pump station can now be equipped with a guide line for proper use of the DOCK-LOCK lifting device in the future. For further information, please contact your Flygt representative. It is also recommended that the DOCK-LOCK lifting system should be used in shallow pump stations where visible contact with the pump is possible and in L and P pump installations. 11

12 Practical handling advises The use of the DOCK-LOCK lifting device needs practise before use to ensure smooth and safe operation. In this chapter you can find some usefull experiences from the field. After lowering the pump in its final position, difficulties in releasing the DOCK-LOCK hook from the lifting link on the pump can occur. To solve that, a nylon rope can be attached to the DOCK-LOCK hook for easier release. Pull the attached rope when the DOCK-LOCK hook has opened. For easier handling of the cables when lifting the pump, use a lifting chain connected to the DOCK- LOCK. When the DOCK-LOCK is connected to the lifting link on the pump, lift the pump approx. 300 mm to avoid lifting in the cables. Connect a lifting string between the hook of the cable suspension and the lifting chain. Use a schackle for connecting the string to the chain. For easier handling when the DOCK-LOCK is connected to a large lifting equipment, use a 1 m long lifting chain between the DOCK-LOCK and the hook. 1 m 12
