2-3.2.1. Tighten evenly, and to a moderate torque, the nuts of any three of the four receiver
feet. Check the unit for level. If the unit is not level, insert metal shims, as shown in Fig-
ure 2-2 under one or two of the feet to obtain level, and retighten the nuts.
2-3.2.2. Note the distance the unanchored foot is elevated above the base and insert a metal
shim of the necessary thickness under this foot to provide firm support.
2-3.2.3. After all shims are inserted and the unit is level, pull up the nuts on all receiver
feet to a moderate (not excessively tight) torque.
BELT GUARD. The enclosed belt guard provides protection front and back as well as
at the top and sides. A screened front allows ample air circulation across the aftercooler
and intercooler while protecting personnel from contact with rotating parts and moving belts.
CLEARANCES FOR ACCESS. With, the exception of the air compressor cylinders,
room for access to all parts of the compressor for service or removal is available within
the overall dimensions of the compressor, providing the 15 inch space for ventilation is main-
tained between the aftercooler and the nearest wall. A clearance of at least 12 inches should
be provided over the unit to allow removal of the cylinders.
MECHANICAL ASSEMBLY PROCEDURES. The air compressor is shipped with the
air hose and inflator gauge assemblies packed separately. Installation of these components
will complete the required mechanical assembly procedures. In the event a remote location
for the air inlet filter silencer is chosen, make the inlet line as short and direct as possible
and as large as, or larger than, the inlet connection at the compressor.. Increase the diam-
eter of the inlet pipe for every 50 feet in length. Attach the air inlet filter silencer to the
end of the inlet air line.
TESTING FOR SATISFACTORY INSTALLATION. After all wiring is completed, "jog"
or "inch" the motor to make certain the compressor rotates in the same direction as that in-
dicated by the arrow on the compressor flywheel. Soon after receiver pressure has built up
for the first time, go over all piping joints made during installation to be certain there are
no leaks. Soapy water applied to the joints will disclose any leaks.
