temperature changes. Two signs of excessive humidity are external
condensation on the pump when it cools down and a "milky"
appearance in compressor oil. You may be able to prevent
moisture from forming in the pump by increasing ventilation or
operating for longer intervals.
Electrical Wiring
WARNING: Improper electrical installation of this product may
void its warranty and your fire insurance. Have circuit wiring
performed by qualified personnel such as a licensed electrician who
is familiar with the current national electrical code and any prevailing
local electrical codes.
WARNING: Risk of electrical shock. Improper electrical grounding
can result in electrical shock. The wiring should be done by a
qualified electrician.
Refer to the air compressor's specification label for the unit's
voltage and amperage requirements.
For best performance and reliable starting, the air compressor
must be plugged into a dedicated circuit, as close as possible
to the fuse box or circuit breaker. The compressor will use the
full capacity of a typical 15 amp household circuit. If any other
electrical devices are drawing from the compressor's circuit, the
compressor may fail to start. Low voltage or an overloaded circuit
can result in sluggish starting that causes the motor overload
protection system or circuit breaker to trip, especially in cold
conditions.
NOTE: A circuit breaker is recommended. If the air compressor is
connected to a circuit protected by a fuse, use only time
delay fuses.
WARNING: Risk of electrical shock. Electrical wiring must
be located away from hot surfaces such as manifold assembly,
compressor outlet tubes, heads, or cylinders.
Grounding Instructions
1. This product must be grounded. In the event of an electrical
short circuit, grounding reduces the risk of
electrical shock by providing an escape wire for
the electric current. This product is equipped
with a cord having a grounding wire with an
appropriate grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
WARNING: Improper installation of the grounding plug is able to
result in a risk of electric shock. When repair or replacement of the
cord or plug is required, do not connect the grounding wire to either
flat blade terminal. The wire with insulation having an outer surface
that is green with or without yellow stripes is the grounding wire
2. Substitution of the signal word "DANGER" for "WARNING" is
not prohibited when the risk associated with the product is such
that a situation exists which if not avoided will result in death or
serious injury.
Check with a qualified electrician or serviceman when the
grounding instructions are not completely understood, or when
in doubt as to whether the product is properly grounded. Do not
modify the plug provided; if it does not fit the outlet, have the
proper outlet installed by a qualified electrician
3. This product is for use on a nominal 120-V circuit and has a
grounding plug similar to the plug illustrated in the figure. Only
connect the product to an outlet having the same configuration
as the plug. Do not use an adapter with this product.
