STS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
When selecting the location of the humidifi er, consider the following:
•
Maximum ambient temperature for control cabinet is 104 °F (40 °C).
• Noises inherent to operation such as STS water fi ll cycles
• Easy access for maintenance
•
Critical service and maintenance clearances around humidifi er — primarily
top, left side, and front (see Figure 7-1).
•
Convenient location to dispersion system for routing of steam hose or tubing
•
Electrical connections — power, control, and safety circuits
•
Steam supply piping connections — inlet steam piping, condensate piping,
and optional equipment (see Figure 26-1)
•
Plumbing connections — supply water, drain piping, and condensate return
piping
• Water seal requirements
•
Avoid locations above critical equipment or processes to avoid damage to
the equipment below in the event of a water leak.
•
Avoid locations close to sources of electromagnetic emissions such as
power distribution transformers and high horsepower motors controlled by
variable frequency drives.
