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