INSTALLATION AND OPERATING MANUAL
255570 (Rev. 1) 11/19
This manual is written to cover the following contact-less claw compressors. The model number is stamped into
the nameplate with serial number: CA3, CA5, CA7L, CA7, CA10, CA15
Please identify the model number and serial number when ordering parts.
1.0 INSTALLATION
1.1 General description
The claw compressor is a dry and contactless machine, enclosed in an acoustic sound shied and designed to
have cooling air passed through the sound shied by a fan. The warm air is exhausted through the vent. The unit
is constructed with modular construction, consisting of (2) two compartments: pumping and gear chambers
separated by using labyrinth seals. In the pump chamber, as two rotary claws rotate in opposite directions, the
air is sucked in and is compressed and discharged under pressure. In the gear chamber (box), two gears for
synchronizing of claw rotation are lubricated. For reduction of noise, an inlet silencer is installed in the
compressor inlet side. For overload protection, a pressure safety valve or regulating valve is installed in the
exhaust. The compressors are direct driven by a flanged motor via a coupling.
1.2 Unpacking
Inspect the box and compressor carefully for any signs of damage incurred in transit. Since all compressors
are ordinarily shipped F. O. B. from our factory or regional warehouse, such damage is normally the responsibility of
the carrier and should be reported to them.
The compressor is bolted to the skid with studs that are connected through the rubber feet of the compressors.
Remove the nuts from the underside of the crate and remove the compressor. Unscrew the studs from the
rubber feet.
The inlet and exhaust of the compressor are covered with plastic caps to prevent dirt and other foreign
substances from entering compressor. Leave these caps in place until you are ready to pipe the compressor to
your equipment.
1.3 Location
Install the compressor in a horizontal position on a level surface so that the pump can be evenly supported on its
rubber feet. Leave 12” ~ 18” of access around the compressor to allow proper cooling. Also, adequate ventilation
must be provided for proper cooling,
Allow access to the oil sight glass in order to inspect the oil level regularly, and the oil fill and oil drain port for easy
service.

A schematic diagram for the electrical motor terminal connections is in the junction box of the motor or on the
motor nameplate. Typical wirings for Three Phase Motors are as below:
Wiring Scheme- Three Phase Motor
Low Voltage
High Voltage
The motor must be connected according to the electrical codes through a fused switch in order to
protect the motor against electrical or mechanical overload conditions. The overload of the motor starter
must be set at a level equal to the full load motor current listed on the motor nameplate.
If the compressor is supplied with a motor starter, it is preset at the factory according to customer specifications.
It is advisable to check that these settings are in line with the voltage at your location. If the voltage
is different, please contact Ohio Medical for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counterclockwise when
looking at the motor from the motor's fan side.
After electrical connections have been made, the rotation of the motor should be checked. If backward,
reverse any two leads of the three at the power connection.

Use a pipe size that is at least the size of the compressor inlet connections. Smaller lines result in reduced
compressor capacity.
Compressors operating in parallel on a common main line should have a manual or automatic operated
shut-off valve or positive action check valve, installed in the suction line adjacent to the pump suction flange.
Remove the plastic protective cap from the discharge port prior to connection of compressor to the system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be
connected to the inlet port. Contact Ohio Medical for recommendations.
The following thread sizes are standard on the compressors
@ Inlet Silencer @Exhaust Connection Housing
1.6 Oil Filling of Gear Box
The pump is shipped without oil in gear box. After level installation and correct rotation has been established,
fill the pump with recommended gear oil through the oil fill port. Oil level should be over 3/4 position on the oil
sight glass as shown on the label.
We recommend ISO VG150 gear oil or equivalent oils.
The following table gives the approximate quantities of oil required for each model.
·
Ohio Medical 220 wt. synthetic oil—Part # 249227—Quart, 249225--Gallon
Do not add fill oil with pump running! Do not overfill.

3.0 OPERATION
3.1 Start-up
Check rotation of the motor as described in paragraph 1.4 Power Requirements.
Fill the compressor with oil as described in paragraph 1.5 - Oil Filling
Start the compressor with the inlet closed. Run the compressors for a few minutes and then shut down.
Check the oil level again and make sure the oil level is 1/2 position of oil sight glass.
Add oil though oil fill port, if necessary. Pump oil should only be added when the pump is off
3.2 Stopping the compressor
To stop the compressor, turn off the power.
3.1 Ambient operating conditions & limits
These compressors are designed to run below set pressures according to the motor power for
continuous operation. Operation over maximum pressure level may result in failure of and severe
damage to the machine. Pressure Regulator installed in outlet flange is set at maximum allowable
pressure (see the table for set of pressure) at factory.
Caution: Any noncompliance may lead to severe injury to persons and damage to the compressor.
The pressure can be adjusted by turning the stud of pressure regulating valve on the top of valve. The
regulating valve or safety valve is set at the permissible operating pressure and will open to discharge if the
compressor runs over the set pressure for a safety operation.
Caution: Do not run the compressor without regulating valve or safety valve. Do not set the regulating
valve or safety valve at over permissible pressure. The compressor may be damaged
severely.
The standard version is for use of dry air only and may not be used in hazardous areas. Handling of humid air or
gases containing aggressive chemicals is possible only with specialized configured units. Consult Ohio Medical
for assistance.
Also, it is recommended for operating personnel who are working near the compressor to wear ear protectors. If
noise below the designed dBA is required, an external sound enclosure can be added to the system, provided
adequate ventilation is provided
The ambient and suction air temperature must be between 41°F and 104°F deg
Caution: Any noncompliance may lead to severe injury to persons and damage to the compressor

4.0 MAINTENANCE
Ohio Medical compressors require very little maintenance. To ensure optimum performance, the
following maintenance steps should be followed:
4.1 Compressor Lube Oil
4.1.1
Gear Oil Level
Check the oil level on monthly basis. Under normal circumstances it should not be necessary to add oil
between oil changes. A significant drop in oil level means there is an oil leak. Please check the Orings, drain plug or oil sight glass.
Check the oil level only when the compressor is shut off. Replenish oil if it drops below the designated
bottom position of the sight glass,
Caution: Do not add oil while the compressor is running, since hot oil can escape from the oil fill port.
4.1.2
Gear Oil Type and Quantity
See section 1.5 - Oil Filling - for details on oil type and capacity.
4.1.3
Oil Change
Under normal ambient conditions with proper Gear Oil, it is recommended to change the oil every 3,000
operating hours. It is necessary to make the first oil change between 500 ~1000 operating hours.
Caution: If different brand oil is being filled, the old oil must be drained completely from the gear box.
Caution: Above interval of lubrication is based on ambient temperature of 68°F. At 104°F ambient
operating temperatures, it may be shortened to half.
4.2 Inline (Inlet) Filter
Check inline (inlet) element on a weekly basis. The filter cartridge should be cleaned or replaced when
dirty. Contact a service agent for replacement element information.
Check the oil level only when the compressor is shut off. Replenish oil if it drops below the
bottom position of the sight glass.
Caution: Depending on the mounting position of the filter, be careful not to allow accumulated
foreign material to fall in the pump suction inlet when removing the filter cartridge. Horizontal filter
installation is recommended to prevent this.

Page 9
255570 (Rev. 1) 11/19
4.3 Maintenance Schedule:
Weekly: Check inline inlet filter element. More often if high particulates in inlet stream
Monthly: Check the oil level, Protective Mesh.
Semi-Annually: Check cooling fan and coupling
Annually: Check Bearings/ Shaft Seals, more frequently if operated at ambient temperature exceeding
68°F
Every 3000 operating hours:
Check the gear oil conditions, and if necessary, change the oil.
Inspection hole with G1" plug: Check the coupling and its insert, and fan through this hole regularly.
