NXW REVERSIBLE CHILLER INSTALLATION MANUAL
Mounting Units
Remove the unit from the wooden shipping skids (see Figures 1 and 2). Units will be shipped with heavy duty rubber
grommets to reduce sound that can be transmitted through the floor via the frame (see grommets below). For additional
sound attenuation, use heavy duty spring isolation that can reduce sound levels by 3 dBA (see springs below).

Unpacking the Unit
Remove the stretch warp and protective cardboard from the unit. Where applicable, remove the compressor shipping
brackets located at the base of each compressor. To do so, lift up the bottom of the compressor sound jacket and remove
the two bolts that hold the bracket (see Figure 3a). Discard the brackets. On NXW540, the hold down shipping bolts should
then be removed and discarded (Figure 3b).
