INSTALLATION
CONGRATULATIONS on your new Curtis
Challenge Air Compressor. Please examine the
compressor for shipping damage(s) and if any are
found report it immediately to the carrier.
Select a clean dry location with a rigid floor strong
enough to support the compressor. If the
compressor is to be located in an area where
vibration is critical, properly engineered vibration
mounts and flexible piping should be used.
Remove the skid. NOTE: The compressor should
never be operated on the shipping skid. Level
the compressor so it can be bolted down securely.
Before tightening the bolts, check to see that all
four feet are resting on the foundation. Shim as
necessary to eliminate stress on the receiver or
base when the bolts are tightened. We suggest
using a level for proper alignment.
Maximum ambient temperature in which the
compressor and motor should be operated is
104°F. Therefore, adequate ventilation must be
provided.
The suction openings of the compressor are
equipped with a combination air filter-muffler to
protect the compressor from normal dust and other
harmful substances. If the air around the
compressor is excessively hot, dusty, humid or
contaminated with foreign gases (such as ammonia
or acid fumes) move the filter-muffler to a remote
point where the air is clean, cool and dry. Run a
pipe to the compressor suction opening. If the run
is over 50 feet in length, use a larger pipe to avoid
excessive pressure drop. In order to fit the filter to
the compressor, bush down the connections. Be
sure piping and fittings are clean and free from dirt
and chips. If the filter is installed outside, check to
insure that it is located above the normal outside
dust level, and that rain cannot enter the filter
element. Where the relocation of the filter-muffler
is not possible or feasible, an oil bath filter is
recommended and is available from Curtis.
On basic or base mounted compressors run a
discharge pipe to the receiver or optional
aftercooler and bush up or down as necessary.
The pipe should enter near the top of the receiver.
Keep in mind that condensate may form in the
discharge line; therefore, the lines should always
be pitched to drain condensate away from the
compressor. Always provide a safety relief valve in
the discharge line between the compressor and in-
line shutoff valves. If more than one compressor
pumps into a common system, a check valve in the
discharge line of each compressor is recommended
to prevent moisture from entering the cylinder head
when one compressor is idle. A globe or gate valve
installed in the discharge line will allow compressor
isolation from plant air system for compressor
maintenance. (Note: A safety relief valve should be
located between the compressor and the
globe/gate valve.)
Check the electrical supply for voltage, phase, and
frequency to see that they match the nameplate
stampings on the motor, magnetic starter,
solenoids, and other controls. Use electrical wires
of adequate size to carry the full load current of the
motor without excessive voltage drop. Charts are
available from Curtis (upon request) to provide
information on this. The motor must always be
protected by a starter with properly sized thermal
overload(s). The starter should protect the motor
from overheating and burnout due to an overload,
low voltage or single phasing of a 3-phase circuit.
Failure to install the proper starter and
overloads will void the motor manufacturers
warranty. Follow the National Electric Code or
local electric code in providing wiring, fusing and
disconnect switches. NOTE: Do not close the
disconnect switch to start the compressor until
the procedures outlined under "Startup
Procedures" have been completed.
LIMITED SAFETY PRECAUTIONS
(Also see supplement LV-474)
The following safety precautions are recommended
in the use of this compressor:
1. Use a totally enclosed OSHA-approved belt
guard to cover the drive assembly. Where
possible, place the flywheel toward the wall, and
mount the unit a minimum distance of 2 feet from
the wall for maintenance convenience.
2. Turn off & lock out the electrical disconnect
switch before working on the unit to prevent the
unit from starting unexpectedly
3. Release all air pressure from the system before
working on the unit and red tag all electrical
control switches, for safety precaution.
4. Do not by-pass motor over-current protection.
5. Do not change the setting or in any way affect
the operation of the safety valve.
6. Keep unit securely anchored so that movement
will not put a strain on piping, wiring, or air
receiver.
WARNING: Read and understand supplement LV-474 before installing and operating the compressor.

START-UP PROCEDURES
OIL RECOMMENDATION
Use Genuine CURTISLUBEPLUS Lubricants. Specially
formulated for Curtis Reciprocating Air Compressors. Non-
Detergent type with anti-foam, anti-rust and oxidation inhibitors.
Recommended ISO68 RC-1000 Premium Reciprocating
Compressor Lubricant, Part no. VO411-3, 12-quart case or
VO411-2, 4 gallon case.
Recommended ISO100 RC-1000A Premium Reciprocating
Compressor Lubricant Part no. VO421-3, 12-quart case or
VO421-2, 4 gallon case.
CURTISLUBEPLUS Lubricants are available through your
authorized Curtis distributor.
If the compressor is equipped with an automatic start-stop
control (with pressure switch unloading), it is automatically
unloaded upon starting, and will automatically load after
attaining running speed. If the compressor is equipped with
a constant speed control (pilot valve unloading), it is
necessary to manually unload the compressor, if there is
pressure in the discharge line, in order to achieve an
unloaded start. The compressor must be manually loaded
after the compressor has attained full running speed, there
after, it functions automatically to maintain operating
pressure until the unit is shut off.
Close the disconnect switch and start the compressor.
Observe the direction of rotation, which should be
counterclockwise when viewed from the flywheel side of the
compressor on all models. For single-phase units, the
direction of rotation is determined by the motor nameplate
instructions, and is adjusted at the factory. For three-phase
units, if the rotation is incorrect, stop the unit and
interchange any two of the three wires to the motor at the
disconnect switch. This will reverse the direction of rotation
of the motor and compressor.
PREVENTIVE MAINTENANCE
A good maintenance program will add years of service to your air
compressor. The following is recommended as a minimum
maintenance program. (TURN OFF POWER BEFORE
SERVICING.)
LUBRICATION
1. For proper lubrication the compressor shall not be
operated below the minimum or above the maximum R. P.M.
recommended for the various models.
2. Maintain oil level mid-way between the upper and lower lines
of the crankcase sight gage. NOTE ILLUSTRATION:
3. Stop compressor to add and gauge oil.
4. Do not fill above the upper line and do not operate compressor
with oil level below the lower line.
DO NOT OVER FILL
5. Change oil at the first 100 hours of operation and 1000 hours
thereafter, or as required. It may be necessary to change oil
more frequent due to abnormal humid and contaminated
conditions.
DAILY MAINTENANCE
1. Check and maintain oil level at centerline of sight glass and
add oil as necessary.
2. Drain condensate from receiver unless it is equipped with an
automatic tank drain, in which case the drain should be
checked weekly to see that it is operating. See automatic tank
drain instructions.
3. Check for unusual noise or vibration (See "Trouble Shooting".)
WEEKLY MAINTENANCE
1. Clean the air filters. A clogged air filter can seriously affect the
efficiency of the compressor and cause overheating and oil
usage.
2. Clean all external parts of the compressor and driver. Be sure
to clean the intercooler-finned surface on two-stage
compressors. A dirty compressor will cause abnormally high
discharge temperature and resulting oil carbonization on
internal valve components
3. Check the safety valve manually (by pulling ring or lever) to
see that it is not stuck.
MONTHLY MAINTENANCE
1. Inspect the entire air system for leaks.
2. lnspect condition of oil and change if necessary.
3. Check drive belt tension and tighten if needed.
EVERY 3 MOS. OR 1,000 HRS. OF OPERATION
1. Change oil.
2. lnspect valves. Clean the carbon from valves and head if
necessary.
3. Check and tighten if necessary all bolts, nuts, etc.
4. Check unloader operation.
*CHECKING BELT TENSION
The v-belt(s) should be adjusted so that a declination of about 3/8
– 1/2 inch will be obtained when it is pushed by a finger at the
middle point as shown in Figure 1.
CAUTION: Over tightening the v-belt(s) will result in
overloading of the motor and belt failure, while a loose belt
will be slipping and resulting in an unstable speed,
overheating the belt and high amp draw.
WARNING: Read and understand supplement LV-474 before installing and operating the compressor.

Figure 1
To change tension, loosen the motor hold-down bolts and
slide the motor on the base, using a lever if necessary, or
by turning the adjusting bolt at the end of the base.
Retighten motor hold-down bolts.
NOTE: Do not over tighten belts.
ELECTRIC MOTOR
Grease once a year with a good grade of lithium ball
bearing grease, or as directed by the motor manufacturer.
VALVE INSPECTION AND MAINTENANCE
Valves should be inspected at regular intervals as
recommended under "Maintenance" and cleaned or
replaced when necessary. The valve can be serviced
without disconnecting air piping or removing the head.
(Be sure the power to the motor is disconnected and
all pressure released before starting to work on the
compressor.)
On constant run models, it is necessary to remove the
unloader piping before the valve plugs can be removed.

PISTON RINGS (Rebuild Kit)
To inspect or replace piston rings as follows:
1. Remove cylinder head.
2. Remove cylinder.
3. Loosen the connecting rod bolts.
4. Push out the piston with piston rings and connecting
rod.
5. To remove the old rings, pry them out of their grooves
and slide them over the piston. Care should be taken
not to damage the piston.
6. Inspect the ring grooves for nicks and carbon deposits.
Clean the ring grooves and remove the obstructions,
which might prevent the rings from moving freely.
To install new rings on the piston as follows: (Be
careful not to damage the piston and rings).
1. Install the oil control ring (70123-61050) first. Rotate
ring in groove to make sure it is free.
2. Install the Compression ring (70123-61030). Make sure
the "top" or "R" mark is exactly on top. If not, it might
cause excessive oil consumption.
3. Repeat the process with other rings, if any.
4. Assemble connecting rod into the crankshaft. Be sure
that the connecting rod and its cap are in original pair
and position, since the connecting rod cap and
crankshaft pin bushing are selected fitted and are not
