Storage
If the chiller is to be stored more than one month prior to
installation, observe the following precautions:
• Do not remove the protective coverings from the

electrical panel.
Capacities
• Store the chiller in a dry, vibration-free, secure area.

at the unit.
• Provide flexible conduit for electrical connections to the
unit.
• Isolate all pipe hangers and be sure they are not
supported by main structure beams that could
introduce vibration into occupied spaces.
• Make sure that the piping does not put additional stress
on the unit.
NOTE: Do not use metal braided type eliminators on the
water piping. Metal braided eliminators are not effective
at the frequencies at which the unit will operate.
