2.3 The machine must be leveled in all directions and must be firmly mounted.
2.4 The flywheel, which is also a fan for circulating air over the cylinder, should never be
placed closer than 12” against the wall, so there is plenty of cooling air circulation.
2.5 Improper installation and maintenance may result in abnormal conditions such as:
1) Insufficient cooling, higher ambient temperature, insufficient cooling space, and
incorrect rotation direction all may easily result in over heating the compressor,
electric motor and compressed air.
2) Placing the unit in a damp and dusty environment may fill the compressed air
with high moisture and create damage to the control system.
3) Severe vibrations will happen when feet are uneven or mounted on a non-solid
floor or nuts and bolts are not securely tightened.
3. V-Belt Adjustment
3.1 Keep the grooves of flywheel and motor pulley clean.
3.2 Align flywheel with pulley groove when installing the V-belts.
3.3 Over tightened belts can cause extra load and shorten the life of the motor bearings.
Overly loose belts can cause V-belt slippage, reduce efficiency and break V-belt.
3.4 Maintain the proper belt tension.
1) Use belt adjuster to correct belt tightness (adjust the tightness according to belt
type, center distance and belt length).
2) Push the belt at its central point by hand to check the belt tightness as below:
Press down firmly on each individual belt and check the deflection to be .8” as
shown on the following picture.
4. Safety Device
4.1 Besides Automatic pressure switch and Automatic unloader as standard protective
components, the following optional safety accessories are also available.
4.2 The air compressor should be equipped with a relief valve to avoid any danger
from excess pressure. The relief valve is designed according to Pressure Vessel
regulations.
