Supplementary service includes such uses as
furnishing air at pressure not carried in regular
shop lines, air at isolated locations, and stand-
by service for air when larger compressors are
shut down.
GENERAL INFORMATION
This manual provides safe and reliable instruc-
tions for the installation, operation and main-
tenance of your air compressor. Carefully read
this manual before attempting to operate or
perform any maintenance. If you are uncertain
about any of the instructions or procedures
provided in this manual, contact an authorized
service center. We recommend you retain this
manual, and all publications provided with
your air compressor, in a location which is ac-
cessible to all personnel who operate and ser-
vice your compressed air equipment.
RECEIPT & INSPECTION
Ensure adequate lifting equipment is available
for unloading and moving the unit to the in-
stallation site.
NOTE: Lifting equipment must be properly
rated for the weight of the unit.
CAUTION: Lift the unit by the shipping skid
only. Do not use the motor lifting eye to lift the
entire unit. The motor lifting eye is for remov-
ing the motor from the unit only.
CAUTION! Do not work on or walk under
the unit while it is suspended.
INSTALLATION
SELECTING A LOCATION.
ELECTRIC MOTOR UNITS. For most electric mo-
tor units, select a relatively clean and dry well-
lighted indoor area with plenty of space for
proper ventilation, cooling air flow and acces-
sibility. Provide 1,000 cubic feet of fresh air per
5 horsepower. Locate the unit at least 15 inches
(38 cm) from walls, and make sure the main
power supply is clearly identified and acces-
sible. Unless the electrical components of the
unit are specially protected for outdoor use, do
not install an electric motor unit outdoors or in
an area that will expose the electrical compo-
nents to rain, snow or sources of appreciable
moisture.
AMBIENT TEMPERATURE CONSIDERATIONS.
Ideal operating temperatures are between 0°C
and 37.8°C. If temperatures consistently drop
below 0°C, install the compressor in a heated
area. If this is not possible, you must protect
safety/relief valves and drain valves from freez-
ing. If temperatures are consistently below
16
4.4°C, consider installing an external crankcase
heater kit, especially if the compressor has dif-
ficulty starting.
CAUTION: Never operate the compressor
in temperatures below -26.1°C or above 40°C.
HUMID AREAS. In frequently humid areas,
moisture may form in the pump and produce
sludge in the lubricant, causing running parts
to wear out prematurely. Excessive moisture is
especially likely to occur if the unit is located in
an unheated area that is subject to large tem-
perature changes.
Two signs of excessive humidity are external
condensation on the pump when it cools down
and a "milky" appearance in petroleum lu-
bricant. You may be able to prevent moisture
from forming in the pump by increasing venti-
lation, operating for longer intervals or install-
ing an external crankcase heater kit.
NOISE CONSIDERATIONS. Consult local officials
for information regarding acceptable noise
levels in your area. To reduce excessive noise,
use vibration isolator pads or intake silencers,
relocate the unit or construct total enclosures
or baffle walls.
MOUNTING
WARNING: Remove the unit from the skid
before mounting. The compressor must be
bolted to a firm, level, solid foundation (such
as a concrete floor) using the vibration isola-
tion pads. Installation on I-beams, open-grid
flooring systems, or non-solid surfaces is not
recommended.
A) Level concrete floor
B) Foundation bolt /
anchor
C) Isolation pad
D) Compressor mount-
ing foot
E) Washer
F) Nut
NOTE: Failure to install the unit using the pads
provided with the unit and in accordance with
the installation instructions as outlined in the
operator's manual may result in mechanical
failure to the compressor and cancellation of
package warranty coverage. URREA bear no
responsibility for equipment installed on non-
approved vibration isolation mounts or non-
solid surfaces.
After the unit has been anchored into position,
check the unit for level by placing a level on
the subbase and checking the readings from
