SOUND ATTENUATION

The following sound attenuation option is recommended for residential or other similar 

sound sensitive locations.

Ultra Quiet Fans

 – The chiller is equipped with specially designed fans and motors to pro-

vide lower sound levels yet retain appropriate airflow. The result is reduced fan generated 

sound with minimal effect on the chiller capacity or efficiency at standard AHRI conditions. 

The fans are three-bladed for 60Hz and five-bladed for 50Hz.

VIBRATION ISOLATION

Vibration Isolators

 – Level adjusting, spring type 1” (25.4mm), 2” (50.8 mm) deflection, 

or neoprene isolators for mounting under unit base rails. 

(Field installed.)
