4.1.2 Guidelines for mechanical installation
The arrows on the pump unit body indicate the flow and the rotation direction of the motor
The standard rotation direction of the motor is clockwise (looking at the fan cover)
Install the booster set in a well ventilated room, leaving sufficient clearance (at least 0.5 m) on
each side and at the front for the purpose of maintenance; there should also be a clearance of
0.5 m above the highest part of the booster set
Place the booster set on a flat and solid surface, without fixing it down
Mount expansion joints and suitable supports for the pipes to protect these against stress, see
Figure 7. The weight of the pipes and pressure tanks increases when they are filled with
water. Before starting the set, make sure you have closed and tightened all the unused
couplings.
