Pre-Installation
Unit Inspection
When unit is delivered, verify it is the correct unit and is
properly equipped. Compare information on the unit
nameplate with ordering and submittal information.
Inspect all exterior components for visible damage. Report
any apparent damage or material shortage to carrier and
make a “unit damage” notation on carrier’s delivery
receipt. Specify extent and type of damage found and
notifyTrane Sales Office. Do not proceed with installation
of a damaged unit without sales office approval.
Inspection
To protect against loss due to damage in transit, complete
the following steps upon receipt of 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.
NotifyTrane sales representative and arrange for repair.
Do not repair unit until damage is inspected by the carrier’s
representative.
Storage
Extended storage of outdoor unit prior to installation
requires these precautionary measures:
• Store the outdoor unit in a secure area.
• For units that have been charged with refrigerant,
verify the following valves are closed on each circuit:
• Suction service valve (butterfly valve)
• Liquid line angle valve or EXV (EXV is driven closed
whenever circuit is powered)
• Oil line shutoff valves to brazed plate heat
exchangers
Note: Units with factory refrigerant charge (model
number digit 15 = 1) are shipped with suction,
liquid and oil line shutoff valves closed, isolating
most of refrigerant charge in the evaporator. If unit
goes directly into long term storage, it is
recommended that these valve positions be
confirmed.
• For units with nitrogen charge option (model number
digit 15 = 2), units are shipped with valves open. If unit
goes directly into storage prior to refrigerant charge,
confirm all service valves are open.
• At least every three months (quarterly), check the
pressure in the refrigerant circuits to verify that the
refrigerant charge is intact. If it is not, contact a
qualified service organization and the appropriate
Trane sales office.
