In all cases, set the unit in place and level. If antiskid pads are
used, do not use hold down bolts. If hold down bolts are used,
do not use anti-skid pads.
When spring isolators are required, install springs running
under the main unit supports. Unit should be installed on
blocks or shims at the listed free height. Isolator springs should
not be loaded until the installation is complete, then adjust the
springs to the vendor listed compression for the load point.
When securing the isolator, do not over-tighten the mounting
bolts. Over-tightening may result in cracking of the cast isolator
housing and will have a negative impact on the isolation eect.
Installation of spring isolators requires exible piping
connections and at least three feet of exible electrical conduit
to avoid straining the piping and transmitting vibration and
noise.
Mounting locations for each model can be found on the
dimensional drawings starting on page 31 for units with
remote evaporators and page 45 for pump package units.
Neoprene wae pads, supplied by customers, should be
mounted at the dened mounting point locations along the full
rail length.
