Installation 
3-1  Installation Location Considerations
 
As with all equipment installations, follow all applicable codes and 
regulations. 
 
þ  Locate close to the process to reduce piping expense. 
þ  Locate adjacent to drain and city water sources. 
þ  Consult a structural engineer to assure that the floor, mounting 
pad or structural steel support is of adequate strength. 
þ  Allow for required service clearances necessary for condenser 
maintenance and easy access to all components. 
3-2  Making Electrical Connections 
SSC Series systems are designed for three-phase voltage operation. 
Refer to the unit nameplate for proper voltage and amperage 
requirements. 
 
Make sure you provide a correctly sized and protected supply of 
electrical power to the unit. 
 
Important! 
Refer to National Electric Code (NEC) Article 430-24 through 430-26 
for proper feeder conductor and supply disconnect sizing. 
 
Maintain a safe ground and disconnect the power supply before 
servicing the unit.  A qualified electrician should make electrical 
connections, and disconnect and lock out electricity using OSHA 
29CFR 1910.147 standards when you need a service call. 
 
Check serial tag voltage and amperage requirements and make sure 
your electrical service conforms before making any electrical 
connections. Total running amps for the SSC Series systems are 
listed on the nameplate. Customer connections can be run to the 
supply terminals from either side of the unit. Make sure that all 
three phases are wired correctly. If not wired properly, the unit will 
run backwardsAgain, check the unit nameplate for correct 
voltage and amperage.
