CIRCUIT REQUIREMENTS
The Model H3370/H3371 Air Compressor
is wired for 110/120V, single-phase opera-
tion only. The maximum amperage draw
for the machine is 17 amps, with a fusing
level rating of 20 amps.
It is best to operate a compressor on a
dedicated circuit, i.e. a circuit where there
are no other electrical appliances plugged
in. The fuse requirements above assume
the use of a circuit breaker or a slow-blow
fuse. If an unusual load does not exist and
the compressor still breaks the circuit, con-
tact a qualified electrician or our service
department at (570) 546-9663.
110V Operation
Extension Cords
In the event of an electrical short, ground-
ing reduces the risk of electric shock by
providing a path of least resistance to dis-
perse electric current. These machines are
equipped with power cords having an
equipment-grounding conductor. See
Figure 1
. The outlet must be properly
installed and grounded in accordance with
all local codes and ordinances.
Grounding
Figure 1.
Ground plug configuration.
If you find it necessary to use an extension
cord with your compressor, make sure the
cord is rated Standard Service (grade S) or
better. Refer to the chart in the standard
safety instructions to determine the mini-
mum gauge for the extension cord. The
extension cord must also contain a ground
wire and plug pin. Always repair or replace
extension cords when they become worn
or damaged.
Overheating, short circuit and fire
damage will result from inadequate
wiring. Follow the guidelines in this
section.
Potential for electrical shock hazard,
this equipment must be grounded.
Verify that any existing electrical
outlet and circuit you use is actually
grounded.
