3 Installation
3-1 Installation Location Considerations
As with all equipment installations, follow all applicable codes and
regulations.
; Locate close to the process to reduce piping expense.
; Locate adjacent to drain and city water sources.
; Consult a structural engineer to assure that the floor, mounting
pad or structural steel support is of adequate strength.
; Allow for required service clearances necessary for condenser
maintenance and easy access to all components.
3-2 Making Electrical Connections
SCW 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
29 CFR 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 SCW 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 backwards. Again, check the unit nameplate for correct
voltage and amperage.
