• Equipment shall not be dropped onto hard surfaces & should not be dragged along the ground.

7.3        Storage

            7.3.1  Storage on Site Store

• To ensure that deterioration of Water Booster Pumps does not occur during storage, it is recommended to store the pumps & its components in sheltered conditions that are protected from weather elements and accidental damage.
• Water Booster Pumps & its components shall be protected with plastic or cardboard and the area shall be barricaded with warning signs.

            7.4 Sequence of Installation for Water Booster Pumps:

7.4.1 Safety

• All site safety rules & regulations shall be complied with.
• Supervisors will deliver tool box talks, relevant to these activities to all operatives involved in the installation, testing & commissioning and shall be recorded.
• All operatives will be equipped with minimum personnel protective equipment; hard hat, coveralls, safety boots, safety glasses.

7.4.3 Installation Procedure

• Prior to installation, ensure that the data on the name plate matches with the required system data i.e. operating voltage, frequency & pump liquid temperature etc. MIR of the Water Booster Pumps should be approved by the Consultant.
• Prior to placing the Water Booster Pumps Set in concrete plinth, make sure that the anchoring bolts are matching with the Pump steel base anchoring hole alignment.
• Lay-out, marked & drill the location of the anchoring bolts on the concrete plinth.
• Each pump shall be mounted on a neoprene rubber pad concrete.
• Carefully place the Water Booster Pumps Set into the plinth. Check proper alignment and level by the use of a Torque Wrench.
• Place the nuts with one flat and lock washer, tight the nuts up to the required torque.
• After completion of setting-out of the Water Booster Pumps, lay-out and fabricate the suction & discharge piping and supports.
• Install the fabricated pipes and fittings along with the valves, flexible connectors & strainers as per the approved shop drawings.
• After completion of installation, raise an inspection request thru WIR to the Consultant for acceptance or Approval. Keep record for reference.
