Pre-Installation Considerations
Checklist
The following checklist gives an overview of the recommended pre-installation considerations. Follow the procedures in this section to ensure installation is complete and adequate for proper unit operation.Verify this checklist is complete before beginning unit installation.
Verify the unit size and tagging with the unit nameplate to ensure the correct unit is received.
Inspect the unit for possible shipping damage and make any necessary claims with the freight delivery company immediately.
Before installing the unit, remember to allow minimum recommended clearances for routine maintenance and service. Refer to unit dimensions and clearances on submittals or in the Dimensions and Weights section.
Verify the unit is configured properly prior to beginning unit installation.
Make proper acoustic considerations before installing unit. Do not install unit near sound-senstive locations.
Allow adequate space for service and operating clearances. Reference “Service Access” section on this page.
Make provisions for correct supply power and note electrical connection knockouts locations on the unit submittals or in the Dimensions and Weights section.
Ensure the unit installation location is level.
Receiving and Handling
Shipping Package
Integral air-cooled units ship assembled on skids. Units ship in the unitary configuration, assembled, piped, and charged with refrigerant.
Receiving Checklist
Complete the following checklist immediately after receiving unit shipment to detect possible shipping damage.
Verify that the unit nameplate data corresponds to the sales order and bill of lading (including electrical data).
Visually inspect the unit exterior for physical signs of shipping damage or material shortages.
If a unit appears damaged, inspect it
immediately before accepting the shipment. Remove access panels and check for interior component damage. Make specific notations concerning the damage on the freight bill. Do not refuse delivery.
Report concealed damage to the freight line within the allotted time after delivery. Verify with the carrier their allotted time to submit a claim.
Note: Failure to follow these procedures may result in no reimbursement for damages from the freight company.
Do not move damaged material from the receiving location. It is the receiver’s responsibility to provide reasonable evidence that concealed damage did not occur after delivery.
Do not continue unpacking the shipment if it appears damaged. Retain all packaging.Take photos of damaged material if possible.
Notify the carrier’s terminal of the damage immediately by phone and mail. Request an immediate joint inspection of the damage by the carrier and consignee.
Notify yourTrane representative of the damage and arrange for repair. Have the carrier inspect the damage before making any repairs to the unit.
Unit Storage
Take precautions to prevent condensate from forming inside the unit’s electrical compartments and motors if the unit is stored before it is installed.
Service Access
Maintain adequate clearances around and above the unit to ensure proper unit operation and allow sufficient service access.Trane recommends 36-inches service access on all sides of the unit.
WARNING
Hazardous voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.
Acoustic Considerations
Before determining the final unit installation site, remember that proper unit placement is critical in reducing transmitting sound levels to the building. The ideal time to make provisions to reduce sound transmissions is during the design phase.The most economical means of avoiding a potential acoustical problem is to place units in areas that are not acoustically sensitive.
Unit Location
Install the unit in a dry, indoor area between 50 and 115°F. Choose a location where sound levels, airflow and vibration, commonly associated with heavy-duty commercial equipment, will not be objectionable to occupants. In multiple unit installations, separate the individual units and stagger their location from floor to floor so as not to starve units for air and not to discharge warm condenser air from one condenser into the intake of another condenser. Place thermostats, air supplies and returns so that the individual unit will operate within its zone.
Installation Preparation
Before installing the unit, perform the following procedures to ensure proper unit operation.
1.Verify the installation location is level. To ensure proper unit operation, install the unit level (zero tolerance) in both horizontal axes. Failure to level the unit properly can result in condensate management problems, such as standing water inside the unit. Standing water and wet surfaces inside units can result in microbial growth (mold) in the drain pan that may cause unpleasant odors and serious health-related indoor air quality problem.
2.Allow adequate service and code clearances as recommended in the Service Access section.
3.Position the unit in its final location.
Unit Placement
Install the unit on a firm, level surface.
Installing Optional Accessories Before installing ductwork, install accessories on unit.
