Note:
The shipping brackets that are used to attach the pump to the shipping pallet can be
used for seismic restraint. The shipping brackets are designed to withstand a level 4
earthquake at a ground floor installation.
Obey the instructions that follow when you install the pump:
▪
Make sure that there is no blockage to access the pump electrical supply cable or
the other controls.
▪
Make sure that there is a minimum air gap of 40 mm on all sides of the pump to
allow effective air circulation.
▪
Make sure that the system is on a firm and levelled surface that can support the
mass of the pump.
▪
Make sure that the system is installed away from combustible materials.
▪
You must do a risk assessment of the location and make sure that you can move
the pump safely and as per the local and national manual handling guidelines.
To attach the system to the floor:
1.
Put the M10 (class 12.9) bolts (not supplied) in the slotted holes of the shipping
brackets to attach the the system to the floor.
2.
Tighten the M10 (class 12.9) bolts.
3.
If the vibration transmission to the floor is a problem, install the applicable
vibration isolators (not supplied) between the brackets and the tie bolt or the stud.
4.
Level the pump to a maximum of 5 degrees (measured at the pump inlet).
To move the pump:
1.
Attach the correct lifting equipment to all 3 lifting eyebolts. Refer to
on page 8, item 13.
2.
Move the pump carefully to the installation area. Refer to
on page 12 for weight of the pump.
3.
Adjust the levelling feet (
on page 8, item 4) to make sure
that the dry pumping system is levelled and not supported by the castors. The
recommended jacking height is 5 mm.
4.
Remove the plastic caps from the inlet and exhaust before you connect the pump
to the vacuum system. Use appropriate NW vacuum fittings for the connection to
the system.
Obey the instructions that follows when you connect the pump to the vacuum system:
▪
Connect the pump to an exhaust line to minimize the noise and the exhaust
emissions.
▪
Make sure that the pipeline connected to the pump inlet is as short as possible.
Make sure that the pipeline has a minimum internal diameter to get maximum
pump speeds.
▪
Put support under the vacuum pipeline to prevent the load on the coupling joints.
▪
Make sure that the pump exhaust line is not blocked as a pressure of 3 bar(g) can
be generated in the exhaust pipework. Connect the pump with appropriate
pipework and fittings.
▪
If necessary, install flexible bellows in the system pipelines to reduce the
transmission of the vibration and to prevent the load on the coupling joints. The
