4.5 Fitting the sleeve

1. Fold the sleeve and insert it into the hole (from the outside of
the pit).
2. Unfold the sleeve so that it lies evenly in the hole.
3. LM50/100 sleeves: Pull the sleeve outwards until its collar
touches the inside of the pit all around the hole.
L965 sleeves: Pull the sleeve outwards until its collar touches
the inside of the pit at the positions 3 and 9 o'clock.
See fig. 14.
4. Lubricate the inside of the sleeve with a water-based
lubricant.
5. Chamfer the pipe and press it home.
LM50/100 sleeves: Push the inlet pipe through the sleeve. See
fig. 12.
As it must be possible to pull the pump up through
the pit, the inlet pipe must not project beyond the
sleeve by more than 50 mm.

stop. See fig. 13.

4.6 Pipes with flange connection

If the pit is to be installed at a temperature below 0
°C, loosen all bolts of the flanges and retighten them
when the pit has been installed.
This will prevent stress in the pipes.

5. Installing the pump(s)

Some versions come without the pump(s) installed. For
installation and startup of the pump, see the installation and
operating instructions for the pump.
Lower the pump(s) carefully into the pit in order to
avoid damage to pump(s) and pit.

5.1 Fitting the chain

For pumps on auto coupling, we recommend that you fit the chain
in the foremost lifting eye of the lifting bracket. The number of
lifting eyes depends on the pump.

WARNING
Crushing hazard
Death or serious personal injury
- The lifting equipment used for lifting the pump
must be rated for the weight of the pump,
approved and maintained according to local
regulations.
Chains supplied by Grundfos are marked with
maximum load and production date.
Do not exceed the maximum load.
Maintain the chain according to local regulations. We
recommend that you check chains and shackles
supplied by Grundfos at least once a year for cracks,
corrosion or other irregularities. If you find any
defects, replace the chain or shackles.
