4. Provide report of SYSTEM INSTALLATION VERIFICATION - SIV as required per specifications. 
   • Food Service Equipment Contractor shall secure System Installation Verification (SIV) Manufacturer Service from factory  rack manufacturer to perform an SIV two times during the duration of the project. The SIV is to be by a factory engineer or by factory certified refrigeration mechanic.
   • First SIV, is to supervise the dealer installation of the refrigeration rack, evaporator coils, refrigerant lines etc. providing oversight, direction and inspecting line set installation.
   • The final SIV will be performed during the start-up of the system. Any field related discrepancies that are discovered during the SIV will be brought to the attention of Food Service Equipment Refrigeration Contractor, General Contractor and corresponding trades on site. These issues will be documented and forwarded to the appropriate sales office and design team. During the SIV Manufacturer Service will address any discrepancy that is the fault of the manufacturer at no cost. If SIV Manufacturer Service has to resolve a discrepancy that is a field issue, the General Contractor will be notified and will need to approve the work to be completed either by SIV Manufacturer Service or direct respective trades to remedy those issues.
   • The Food Service Equipment Refrigeration Contractor installer is to inform factory engineer if the installation and start up will take place at the same time, or if the startup will be at a later date. If the startup will be at a later date, the installer is to inform factroy engineer to schedule the SIV dates.
   • The warranties will not go into effect unless this procedure is followed.  

F. Work not included in the Refrigeration Contractors Scope to include the following: 

1. GC to provide pad for refrigeration rack. 
2. Electrical wiring and disconnect to rack. 
3. Interconnecting wiring from rack to freezer evaporator coils. 
4. Piping of condensate lines from all evaporator coils. 
5. Heat trace on freezer section condensate lines. 
6. Penetrations and sealing of penetrations through rooftop and any sleeving of any walls as required. 
7. Low voltage wiring and CAT-5 wiring of alarm system to building system and to control data software in foodservice manager's office. 
8. Piping of condensate lines from all evaporator coils. 

G. Meetings: Participate in regularly scheduled (as required) foodservice specific coordination meetings as scheduled by GC.
