Prior to Use

1. Inspect the product
a. Ensure that all items on the delivery note or packing list are present, and that no items are
damaged.
b. Unpack the goods and visually ensure that all parts are undamaged. Check that bolts and screws
have not come loose during transit.
c. If any issues are identified do not proceed further and immediately contact your Intrax dealer
from whom you purchased the product, or the nearest representative office. The delivery should
not be accepted or signed for prior to completion of all of the above checks.
2. Check the specification
a. Find the nameplate on the pump and verify that it is the one you have ordered.
b. Ensure that the voltage and frequency specifications match the original specification.
c. If any issues are identified do not proceed further and immediately contact your Intrax dealer
from whom you purchased the product, or the nearest representative office. The delivery should
not be accepted or signed for prior to completion of all of the above checks.
3. Method of starting
a. Ensure that the selected starting method is capable of driving your pump. Please note that
electri cal motors are largely inductive, so the current may significantly spike on start-up. As a
general rule:
i. DOL (Direct On Line) start can create a current spike up to approximately 6 times the
rated current.
ii. Soft Start can create a current spike up to approximately 3 times the rated current.
iii. Inverter drive can create a current spike up to approximately 1.2 times the rated current.
b. If a starting method is yet to be chosen, always choose an inverter drive where budget allows,
followed by soft start, and only use DOL where necessary. It is highly recommended to avoid DOL
on all pumps over 18.5kW.
