Make sure that the power supply cannot be switched on accidentally.
4.2.1 Lifting the product
Observe local regulations concerning limits for manual lifting or handling. The weight of the product is stated on the nameplate.
CAUTION

Minor or moderate personal injury
‐
Use lifting equipment.
Do not lift the product by the terminal box.
To protect components such as pressure gauge, sensor and tank, Grundfos recommends lifting the product in the same packing it was
delivered in.
•
Always lift the product by means of a forklift if the pump is fixed on a pallet.
• The product must remain in the packaging until installation.
• Mind the weight of the product. The weight is stated on the nameplate.
• Mind the unbalanced load when you lift the product. Most of the weight is on the motor side of the product.
4.2.2 Positioning the product
1. Position the base plate on a plane and solid surface, for example a concrete floor or foundation.
2. We recommend that you use vibration dampers under the base plate.
3. If the base plate is not fitted with vibration dampers, the base plate must be bolted to the floor or foundation through the holes in the base
plate.
4.2.3 Pipe system
We recommend that you use a manifold pipe dimension of 1" to 1½" to carry the maximum flow of both pumps with no additional
pressure loss.
Do not twist the manifold and do not place weight on the pumps or manifold as this can damage the product.
Fasten the pipes to parts of the building to ensure that they cannot move or be twisted.
We recommend that you use the following:
•
Vibration dampers for mounting the base plate.
• Pipe supporting brackets. The pump is not built to withstand the weight of a pipe system.
• Flexible joints, flexible hoses and pipe hangers to reduce vibration noise in the pipe system.
We recommend that you install isolating valves on both the inlet and outlet side of the booster system.
1. Use thread sealing tape or similar to seal the pipe connections.
2. Connect pipes to the inlet and outlet on both pumps.
3. Install the pipes so that air pockets are avoided.
4. If the pump is installed above the liquid level, for example if you pump from a tank or reservoir, you must fit a foot valve in the inlet pipe.
