Installation Instructions for SLM-1A-SLM-3A
1Do not use the SLM-mount under static loads greater than the indicated maximum.
2Do not inflate the SLM unless the static weight of the equipment to be mounted is
placed atop the mount. Read instructions carefully.
3WARNING: SLM mounts should not be pressurized above 60 psi. If in doubt, the
pressure should be checked with a pressure gage, such as Schrader tire gage type 8100.
Models SLM-1A and SLM-3A should be inflated with a bicycle-type pump or
regulated air supply set to 60 psi or less to avoid overinflation.
4Whenever the equipment is to be removed from the mounts, deflate the mounts before
removal of the load.
5The level of the support base as well as the equipment foot should be such that no SLM
between the equipment and the support base will have to be adjusted for level more
than +/-0.25 inches.
A. TO INSTALL
1Raise the equipment to a height greater than 2.50 inches and place the SLM mount
between the equipment and the support base.
2Insert the center bolt and engage the threads in the mount. Hand tightening is adequate at
this point.
3Lower the equipment, which will come to rest on the mount surface M.
4Tighten bolt.
IMPORTANT: Tightening of the SLM-1A mounting bolt may cause twisting of the top
mounting surface which could result in reduced isolator life. To avoid this possibility,
raise the static load until the mount base plate is free and the isolator twist is relieved. In
cases where the holes in the SLM mounting plate must be aligned with existing holes in
the mounting structure it is permissible to rotate the body of the mount to line up the
holes. If rotation exceeds 5 degrees, however, it will be necessary to loosen the top bolt
and readjust the equipment.
5Lower the equipment and install bolts through the mounting holes provided in the base
plate if mount tie-down is desired.
6Sequentially pressurize each isolator through its valve until dimension X is 1/16 inch for
each mount.
7Continue sequential pressurization of each mount so that dimension X increases in
increments of approximately 1/8 inch until X is 0.5 inches or the overall mount height is
2.50 inches (whichever is more convenient to measure).

B TO LEVEL
1Bleed or insert air to respectively lower or raise the mount height in small increments
until the desired level is reached.
2Check each mount for overall height which should be within 2.50+/-0.25 inches. If
beyond this range, repeat the pressurization/bleed process until the height tolerance
and the desired levels are reached.
NOTE:: If air supply pressure exceeds the indicated requirement for the static load,
the isolator will seek a height greater than 2.50 inches. To install the mount under
such circumstances, the valve is manually bled to reduce to 2.50 inches. If the air
supply pressure is less than the indicated requirement for the static load, a larger
mount may be required.
NOTE:: The equipment foot should cover the entire top surface M of the mount. If
not, a plate of Diameter G should be placed between the foot and the mount.
