enclosure through louvers in the side panels, through
the aftercooler and exhausted through the heat ex-
changer at the top of the unit. The air-- cooled unit with
the standard enclosure requires sufficient flow,
FIGURE 2-- 2, page 9, for the compressor water/after-
cooling system and for electric motor cooling. Do not
block the air flow to and from the unit. Allow three and
one-- half (3-- 1/2) feet to the nearest obstruction on the
control box end of the unit. Allow three (3) feet to the
nearest obstruction above and on other sides of unit.
For continuous efficiency, the heat exchanger and af-
tercooler cores must be periodically cleaned with either
vacuum or compressed air. If wet cleaning is required,
shield the motor and spray on a mild soap solution, then
flush with clean water.
For copper water coolers, do not use
any cleaning solution that is not com-
patible with copper. Use of improper
solution may result in damage to the
cooler.
FOUNDATION
-- The Champion Rotary Screw com-
pressor requires no special foundation, but should be
mounted on a smooth, solid surface. Whenever pos-
sible install the unit near level. Temporary installation
may be made at a maximum 10
_
angle lengthwise or
10
_
sidewise.
Mounting bolts are not normally required. However,
installation conditions such as piping rigidity, angle of
tilt, or danger of shifting from outside vibration or mov-
ing vehicles may require the use of mounting bolts and
shims to provide uniform support for the base.
OIL RESERVOIR DRAIN
-- The oil drain plug is located
at the bottom of the discharge end of the compressor.
(See FIGURE 5-- 1, page 40.)
ENCLOSURE
-- The compressor, electric motor, water
cooler and aftercooler are mounted inside the enclo-
sure.
Service doors are provided for maintenance access.
Be sure to allow enough space around the unit for the
doors to be opened and removed as necessary for ser-
vice procedures. The enclosure doors are held by two
latches and lift away from the enclosure. The air filter,
water filters, and water treatment cartridge are easily
accessible through a side or end door.
Do not operate the compressor with
the belt guard removed. Exposed
belts may cause injury to personnel.
COMPRESSOR WATER SPECIFICATION
-- The
compressor initial fill and make-- up water must meet
the United States Environmental Protection Agency
National Primary and Secondary Drinking Water Reg-
ulations (See Table, page 15.) By requiring potable
water fit for human consumption, a quality level is de-
fined which is most generally readily available.
Backflow
Preventers
must
be
installed on the potable water supply
line to the compressor to preventhigh
pressure air from blowing into the wa-
ter supply.
Use of compressor initial fill and
make--up water not meeting all water
specification standards noted may
result in contamination of the dis-
charge air stream.
Compressor water seal leakage may
occur. You must have potable make--
up water available.
Water may no longer be potable after
use in the compressor.
