INSTALLATION AND OPERATING MANUAL
This manual covers contact-less operating claw type pumps. The model number is stamped into the nameplate with serial number: C3B, C5B, C7LB, C7B, C10B, C15B.
Please identify the model number and serial number when ordering parts.
1.0 INSTALLATION
1.1 General Description
The SELECTORR pump is a dry and contactless machine, enclosed in an acoustic
sound shield and designed to have cooling air passed through the sound shield by fan. The warm air is exhausted through the vent. The pump is constructed in modular construction consisting of 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, compressed and discharged under pressure. In the gear chamber (box), are two gears for synchronizing of claw rotation, providing oil lubrication.
An anti-suck back valve can be installed in inlet ange and will prevent the air from back owing into the vacuum chamber after the pump is shutdown. The pump is directly driven by a anged motor via a coupling.
1.2 Unpacking
Inspect the box and pump carefully for any signs of damage incurred in transit. Since
all pumps are ordinarily shipped F.O.B. from our factory or regional warehouse, such damage is the normal responsibility of the carrier and should be reported to them. The pump is bolted to the skid with studs that are connected through the rubber feet of the pump. Remove the nuts from the underside of the crate and remove the pump. Unscrew the studs from the rubber feet. The inlet and exhaust of the pump are covered with plastic caps to prevent dirt and other foreign substances from entering. Leave these caps in place until you are ready to pipe the pump to your equipment.
1.3 Location
Install the pump in a horizontal position on a level surface so that it can be evenly
supported on its rubber feet. Leave 8" to 10" of access around the pump to allow proper cooling. Adequate ventilation must also be provided for the cooling of the pump and motor. Allow access to the oil sight glass in order to inspect the oil level regularly,
and the oil ll and oil drain port for easy service.
1.4 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the
junction box of the motor or on the motor nameplate. Typical wirings for Three Phase Motors are shown on page 4:

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 pump is supplied with a motor starter, it is preset at the factory according
to customer specications. It is advisable to check that these settings are in line with the voltage at your location. If the voltage is di󰀨erent, 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.
1.5 Vacuum Connections
Use a pipe size that is at least the size of the pump outlet connection. Smaller and long pipe lines result in a reduced pump capacity.
Compressors operating in parallel on a common main line should have a manual
or automatic operated shut-o󰀨 valve, or a positive action check valve installed in the
pressure line. Remove the plastic protective cap from the exhaust port prior to connecting the pump to the system.
Should process gas contain dust or other foreign particles, a suitable inline (inlet)
lter should be connected to the inlet port. Consult Ohio Medical for recommendations.

1.6 Oil Filling on Gear Box
The pump is shipped without oil in gear box.
After level installation and correct rotation
have been established, ll the pump with recommended gear oil through the oil ll port.
Oil level should be over 3/4 position on the oil sight glass as shown on the label.
Contact Ohio Medical for all required oils and greases. We recommend ISO VG150 gear oil or
equivalent oils.
The table gives the approximate quantities of oil required for each model.

3.0 OPERATION
3.1 Start-up
Check rotation of the motor as described in paragraph 1.4 Power Requirements. Fill the pump with oil as described in paragraph 1.6 - Oil Filling.
Run the pump 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 at stop status.
Add oil through oil ll port on the top. Pump oil should only be added when the pump is o󰀨.
3.2 Stopping the Pump
To stop the pump, turn o󰀨 the power. A check valve is installed in the inlet ange that will prevent the air from back owing into the vacuum receiver after the pump is
shutdown.
Caution: In applications, where the quantity of water vapor is moderate, it is
recommended to run the pump for 10 minutes at least with outside air prior to shut down to prevent the vapor from condensing in the pump.
3.3 Operating Conditions
The C3B, C5B, C7LB, C7B, C10B, C15B are designed to run the ultimate vacuum
levels stated in technical data (6.0) for continuous operation. Operation over maximum vacuum level may result in failure of and severe damage to the machine.
Vacuum Regulator installed in inlet ange is set at maximum allowable vacuum at
factory, and a desired vacuum level to below the maximum level can be achieved by rotating the adjustment knob.
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 specially congured units. Consult Ohio Medical for assistance.
Excessive back pressure on the unit may result in excessive current draw. Do not operate the vacuum pump over 2 psi back pressure.

Page 7
Ear protection is recommended for operating personnel who are working near the pump. 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 40°F and 104°F.
Caution: Any non compliance may lead to severe injury to persons and damage to the
pump.
Caution: Maximum number of motor starts per hour should not exceed 10 per hour.
Excessive starting of the motor can cause overheating and premature failure of the motor. A minimum run timer should be used with any panel that may control the pump
with automatic starts and stops based on system pressures.
4.0 MAINTENANCE
SELECTORR® series vacuum pumps require very little maintenance. To ensure optimum
performance, the following maintenance steps should be followed:
4.1 Gear Box Oil
4.1.1 Gear Box Oil Level
Check the oil level on a monthly basis. Under normal circumstances, it should
not be necessary to add oil between oil changes. A signicant drop in oil level
means there is an oil leak. Please check the O-rings, drain plug or oil sight glass.
Check the oil level only when the pump is shut o󰀨. Replenish oil if it drops
below bottom position of the sight glass.
4.1.2 Gear Box Oil Type and Quantity
See section 1.6 - Oil Filling - for details on oil type and capacity.
4.1.3 Gear Box Oil Change
Under normal ambient conditions with proper Gear Oil, it is recommended to change the oil every 3000 operation hours.
