Pre-Installation
Inspection Checklist
When the unit is delivered, verify that it is the correct unit
and that it is properly equipped. Compare the information
which appears on the unit nameplate with the ordering
and submittal information. See “Model Number
Descriptions,” p. 7.
Inspect all exterior components for visible damage. Report
any apparent damage or material shortage to the carrier
and make a “unit damage” notation on the carrier's
delivery receipt. Specify the extent and type of damage
found and notify the appropriateTrane Sales Office.
Important: Do not proceed with installation of a
damaged unit without sales office approval.
To protect against loss due to damage incurred in transit,
complete the following checklist upon receipt of the unit.
• Inspect the individual pieces of the shipment before
accepting the unit. Check for obvious damage to the
unit or packing material.
• Inspect the unit for concealed damage as soon as
possible after delivery and before it is stored.
Concealed damage must be reported within 15 days.
• If concealed damage is discovered, stop unpacking the
shipment. Do not remove damaged material from the
receiving location.Take photos of the damage, if
possible.The owner must provide reasonable
evidence that the damage did not occur after delivery.
• Notify the carrier's terminal of the damage
immediately, by phone and by mail. Request an
immediate, joint inspection of the damage with the
carrier and the consignee.
• Notify theTrane sales representative and arrange for
repair. Do not repair the unit, however, until damage is
inspected by the carrier's representative.
Unit Storage
If the chiller is to be stored for more than one month prior
to installation, observe the following precautions:
• Do not remove the protective coverings from the
electrical panel.
• Store the chiller in a dry, vibration-free, secure area.
• At least every three months, attach a gauge and
manually check the pressure in the refrigerant circuit.
If the refrigerant pressure is below 71 psig at 70 F (or 46
psig at 50 F), call a qualified service organization and
the appropriateTrane sales office.
Note: Pressure will be approximately 20 psig if shipped
with the optional nitrogen charge.
Installation requirements and
Contractor responsibilities
A list of the contractor responsibilities typically associated
with the unit installation process is provided in Table 9.
Note: Unit Start-up must be completed by a qualified
Trane service technician.
