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.
