Pre-Installation
Unit Inspection
To protect against loss due to damage incurred in transit,
perform inspection immediately upon receipt of the unit.
Exterior Inspection
If the job site inspection reveals damage or material
shortages, file a claim with the carrier immediately. Specify
the type and extent of the damage on the bill of lading
before signing. Notify the appropriate sales representative.
Important: Do not proceed with installation of a damaged
unit without sales representative’s approval.
• Visually inspect the complete exterior for signs of
shipping damages to unit or packing material.
• Verify that the nameplate data matches the sales order
and bill of lading.
• Verify that the unit is properly equipped and there are
no material shortages.
Note: Corrosion due to dirt, road grim, road salt, and other
contaminates picked up during shipping is not the
responsibility of the carrier.
Inspection for Concealed Damage
Visually inspect the components for concealed damage as
soon as possible after delivery and before it is stored.
If concealed damage is discovered:
• Notify the carrier’s terminal of the damage immediately
by phone and by mail.
• Concealed damage must be reported within 15 days.
• Request an immediate, joint inspection of the damage
with the carrier and consignee.
• Stop unpacking the unit.
• Do not remove damaged material from receiving
location.
• Take photos of the damage, if possible.
• The owner must provide reasonable evidence that the
damage did not occur after delivery.
Repair
Notify the appropriate sales representative before
arranging unit installation or repair.
Important: Do not repair unit until the damage has been
inspected by the carrier’s representative.
Storage Requirements
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 16 = E) 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 16 = F), 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.
