TM 5-4310-385-13
a.
Before initial start-up, remove either oil fill plug (1) and fill crankcase with 10 oz. (.3 L) of oil of proper viscosity.
Refer to paragraph 3-2. Replace fill plug.
b.
Check oil level on sightglass (2) before and after first operation.
c.
Remove the belt guard (3) and check V-belts (4) for proper tension. Inspect the compressor flywheel and electric
motor drive pulley for secure attachment to shafts.
d.
Before start-up, turn the flywheel over a few revolutions by hand to make sure that there aren't any obstructions
anywhere in the unit.
e.
Inspect the intercooler tubing (5) and aftercooler tubing (6) for dents, crimps, and secure attachment. Inspect
compressor unloader line (7) to the pressure switch for crimping and secure attachment.
f.
Inspect air hose (8) for cuts or cracks or other signs of obvious damage. Inspect the inflator gage (9) for secure
attachment to air hose.
g.
Inspect all hardware for tightness, particularly for compressor unit and electric motor mountings.
3-8. SITE AND SHELTER REQUIREMENT
a.
The compressor was designed for permanent installation in a sheltered environment. Protect the compressor
from water, excessive dirt and corrosive atmospheres.
b.
Compressor must be located in a clean, well ventilated dry place where compressor receives an adequate supply
of fresh, clean, cool and dry air. Allow sufficient space around the compressor so that it is accessible from all sides for
maintenance.
c.
Locate the compressor away from work areas and areas frequently traveled, preferably outside of the
maintenance building. A special noise reduction enclosure may be necessary.
d.
Locate the compressor where appropriate three phase, 208 V electrical power with a separate ON/OFF switch
may be installed.
e.
For proper cooling, insure that no object will obstruct the flow of air through the slotted belt guard to the fan
bladed flywheel.
f.
Compressor requires a space approximately 3' x 2' (1 m x .6 m). Locate compressor at least 12" (30.5 cm) from
any wall on a solid, level base.
3-9. INSTALLATION INSTRUCTIONS.
a.
Compressor must be installed on a solid, level base. If compressor is to be used as a portable unit, compressor
can be left bolted to bottom skid. Compressor and skid must be placed on firm level ground or flooring to minimize
vibration and ensure proper operation.
CAUTION
Do not eliminate space between the base and a foot by drawing the foot down.
This would stress the tank foot and result in abnormal vibration and possible
damage to the tank.
b.
For permanent installation, bolt the compressor securely and evenly to a level base. If flooring or base is not
completely level, shims must be used under the feet.
WARNING
Power must be shut off to source line before installation service is performed.
Voltages present in this equipment can cause injury or death.
c.
Connect the magnetic motor starter to 208 VAC 3 phase line with a separate ON/OFF switch.
d.
Before power is applied to unit, check all other wiring terminals in the starter enclosure and pressure switch for a
secure fitting.
