Inspection
Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the packaging of each unit, and inspect each unit for damage. Insure that the carrier makes proper notation of any shortages or damage on all copies of the freight bill and completes a common carrier inspection report. Concealed damage not discovered during unloading must be reported to the carrier within 15 days of receipt of shipment. If not filed within 15 days, the freight company can deny the claim without recourse. Note: It is the responsibility of the purchaser to file all necessary claims with the carrier. Notify your equipment supplier of all damage within fifteen (15) days of shipment.
Storage
Equipment should be stored in its original packaging in a clean, dry area. Store units in an upright position at all times. Stack units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either the original packaging or an equivalent protective covering. Cap the open ends of pipes stored on the job site. In areas where painting, plastering, and/or spraying has not been completed, all due precautions must be taken to avoid physical damage to the units and contamination by foreign material. Physical damage and contamination may prevent proper
Examine all pipes, fittings, and valves before installing any of the system components. Remove any dirt or debris found in or on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions are provided with each unit. Horizontal equipment is designed for installation above false ceiling or in a ceiling plenum. Other unit configurations are typically installed in a mechanical room. The installation site chosen should include adequate service clearance around the unit. Before unit
Prepare units for installation as follows:
1.Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped.
2.Keep the cabinet covered with the original packaging until installation is complete and all plastering, painting, etc. is finished.
3.Verify refrigerant tubing is free of kinks or dents and that it does not touch other unit components.
4.Inspect all electrical connections. Connections must be clean and tight at the terminals.
5.Loosen compressor bolts on units equipped with compressor spring vibration isolation until the compressor

CAUTION! DO NOT store or install units in corrosive environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.). Corrosive conditions and high temperature or humidity can significantly reduce performance, reliability, and service life. Always move and store units in an upright position. Tilting units on their sides may cause equipment damage.
NOTICE! Failure to remove shipping brackets from spring- mounted compressors will cause excessive noise, and could cause component failure due to added vibration.
