Associated Equipment 3HP - Manual (Page 3)

Operating Instructions and Parts Manual
Estimate 2 CFM reduction in air flow for each foot of duct; 15
CFM reduction for each 90’ curved bend. Pneumatic
conveyance of wood dust requires a minimum air velocity of
3500 FPM in the hose or duct; higher for heavier materials,
CFM must not be reduced below the level required to provide
this air velocity. ,
A DANGER
Maintenance
High voltage electrical power can
cause severe injury or death. Always
disconnect or lock out from power source and let motor
come to a complete stop before inspecting, moving or
servicing.
A WARNING
High speed rotating equipment can
cause severe persona/ injury.
Disconnect or lock out from power source and let mofor
come to a complete stop before inspecting, moving or
servicing.
MOTOR
The bearings on the electrical motor are lubricated and sealed
for life, so they need no lubrication during use. Keep the motor
clean as excessive dirt may prevent proper cooling. Use no
more than 50 psi air to blow off excessive dirt.
A CAUTION
Wear eye protection while using an
air hose for cleaning.
BLOWER WHEEL AND STEEL COMPONENTS
The cast aluminum blower wheel and steel components are
maintenance free and should not require any maintenance
during the life of the unit.
If a vibrafion should develop, it may indicate excessive wear or
damage to the blower wheel. In this case, with the motor
turned
OFF and LOCKED OUT, inspect the blower wheel. If
any damaged or excessively worn areas are noted, replace
the blower wheel.
A WARNING
Do not operate the dust collector
with a damaged or severely worn
blower wheel. The wheel may disintegrate at operating
speed and high speed fragments may cause death or
severe personal injury and property damage.
FILTER BAG (DO NOT REMOVE WHILE UNIT IS RUNNING)
Periodically check the filter bag for worn or damaged areas.
Replace the bag if worn or damaged areas are found.
A CAUTION
Do not operate with a worn or
damaged filter bag as escaping dust
could lead to respiration (breathing) problems and/or eye
damage or blindness.
If the interior surface of the bag becomes dirty and a
noticeable drop-off in air flow develops, the bag may need to
be cleaned. Disconnect motor or lock out from power source.
Remove the bag and turn inside out. Use low pressure air to
dislodge surface dust. If tlqe dust is lodged below the surface,
the bag may be washed. Wash using a cold water, gentle
cycle, and line dry. If the bag becomes dirty again very quickly,
another fabric type may be needed.
Do not wash felt fabric filter bags which have a surface
coating; gently rinse the coating with water.
Troubleshooting Chart
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Unit will not operate. 1. Improper electrical connection. 1. Turn power OFF - assure unit is wired per
instructions. Check and replace fuse or
circuit breaker as needed but
do not
oversize for the circuit.
2. Blower wheel loose. 2. Turn unit OFF. Disconnect power cord. Turn
unit over & spin wheel by hand. Reposition
and tighten set screws if necessary.*
Low suction or flow
rate. 1. Incorrect rotation. 1. Turn unit OFF and observe motor cooling
wheel rotation as it stops. Rewire correctly
if necessary.
2. Suction hose too long. 2. Place unit closer to dust source and
shorten hose.
3. Dust bag dirty.
(DO NOT REMOVE WHILE UNIT
IS RUNNING)
3. Clean dust bag. Wash cotton or knit filter
bags in standard washer, line dry. Do not
wash internally coated felt bags; gently
rinse coating with clear water. Replace bag
if needed.
