5 Partial List of Contractor Responsibilities *The following notes are not all inclusive and are not intended to relieve the installing contractor if its responsibilities. By providing this document, we do not accept any responsibility for the proper installation or operation of the equipment General Inspection and acceptance of freight delivery at rigging yard to ensure the equipment has not been bent, twisted, or damaged during shipping, rigging, or installation. Performance of a refrigerant & oil leak check upon initial acceptance of delivery Accounting of all ship loose parts received and stored as per the manufacturer s instructions Check tightness and torque of all electrical connections loosened in transit Additional transport, storage, or offloading of equipment after initial acceptance of delivery Protection and proper storage of equipment and repair of damage from improper storage and handling Provision and installation of external unit vibration isolation, external support steel, or curbs as required Installation of equipment with adequate room for safe startup and service access as well as sufficient airflow supply as to prevent the risk of recirculation of air. Provide technicians to perform startup of the equipment with supervision and training by factory personnel. Complete any additional tasks set forth by the RAE Corporation Startup Checklist two weeks before scheduling of the factory technicians. Any additional responsibilities contained in the specification documents Electrical and Controls Integration Provisions and installation of main 3 phase power connection to each chiller with the proper voltage and connection quantity according to the approved submittal documents and power draw of the chiller Provision of separate control power connection if control transformer is not provided by manufacturer. Installation and termination of all interconnecting wiring noted on the manufacturers wiring diagrams The BMS contractor must have obtained and read the relevant publications from the manufacturer pertaining to whichever protocol he will use before attempting to read / write points to the equipment controller Ensure that the BMS contractor is complete in all aspects of his communication and submit any questions to the manufacturer well in advance of startup. Hardwire connection between standalone chiller controller and building management system. (Applies only if the appropriate BACnet, or Modbus gateway has been furnished by TSI) Fluid Piping Provisions and installation of Supply/Return fluid connections, and any required water makeup and drain connections according to the approved submittal documents. For Evaporative Condenser products, the installing contractor must provide water makeup piping sized to provide the maximum design condenser water makeup rate at a pressure between PSIG. Inadequate supply may result in loss of capacity and / or safety trips. Flushing, filling, cleaning, and pressure testing of the fluid system with the correct type and quantity of glycol as well as completion of flow balancing in all lines prior to date of startup. Installation and wiring of required control valves not provided by manufacturer. Installation and wiring of any noted ship loose parts provided by the manufacturer and installed per their recommendations. Ensure any chilled fluid bypass valves are not located near the refrigeration system. Refrigerant Piping (split systems) Reconnection and installation of refrigerant piping following ASHRAE and industry standards for refrigerant line sizes, trap selection for vertical risers, pitch of horizontal lines, etc Pressure testing of 24 hours with dry nitrogen followed by full evacuation to 500 microns to ensure a leak free and moisture free system. The vacuum must be broken with the system refrigerant. Provision and installation of the required refrigerant and oil according to the proper type and quantity of charge required for proper operation. Page 4 of 5
