1 RECEIPT OF EQUIPMENT
1.1 Inspection
All equipment should be carefully checked for damage or shortages as soon as it is received. Each
shipment should be carefully checked against the bill of lading. If any damage or shortage is evident, a
notation must be made on the delivery receipt before it is signed, and a claim should then be filed against
the freight carrier.
Inspection and claims are the responsibility of the recipient.
1.2 Loss of gas holding charge
The coil section of each Fluid Cooler unit with ODS connections are leak tested, evacuated to remove
moisture, and then shipped with a pressurized nitrogen gas holding charge. Absence of this charge may
indicate a leak has developed in transit. The system should not be filled with fluid until it is verified that
there is no leak, or the source of the leak is located and repaired if necessary. If the coil section has MPT
or flanged connections, the coil is not charged. Once the unit is installed in the system check the coil
during the system pressure test.
