Figure 1: Corner Weights & Center Of Gravity
NOTE: Front of unit is considered the side having the control
box.
Concrete piers can also support ground level units. These piers
should (1) extend below the frost line, (2) be located under each
of the section's four corners, and (3) be sized to carry the load
of the corner it supports.
On either rooftop or ground level installations, rubber padding
can be applied under the unit to lessen any transmission of
vibration.
Holes are provided in the base rails for bolting the unit to its
foundation.
For ground level installations, precautions should be taken to
protect the unit from tampering and unauthorized persons from
injury. Screws on access panels will prevent casual tampering.
Further safety precautions such as a fenced enclosure or
locking devices on the panels may be advisable. Check local
authorities for safety regulations.
