INSTALLATION INSTRUCTIONS - Continued
c. Siting
Unit may be bolted to any substantial, relatively level floor or base.
(1) CLEARANCE FOR ACCESS - A clearance of at least 15 inches should be provided to
allow for maintenance and service.
(2) MOUNTING - should a concrete base be necessary, make certain foundation bolts are
positioned correctly to accept receiver feet. Bolts must project at least 1-3/4 inches above sur-
face of foundation.
(3) LEVELING - to prevent vibration and ensure proper operation, it is important that the
unit be level. Tighten evenly, and to a moderate torque, nuts of any three of the four receiver
feet. Check unit for level. If not level, insert metal shims under one or two of the feet to obtain
level.
(4) Note distance unanchored foot is elevated above base and insert metal shim of necessary
thickness to provide support.
(5) After all shims are inserted and unit is level, pull up nuts on all receiver feet to moderate
(not excessively tight) torque. (Refer to Appendix F).
(6) Check for stress by loosening nuts (one at a time) and note any upward movement of
mounting foot.
