INSTALLATION AND OPERATING MANUAL

This manual covers the C30 contact-less operating claw type vacuum pumps. The model number is stamped into the nameplate with serial number: C30.

Please identify the model number and serial number when ordering parts.

1.0 INSTALLATION

1.1 General Description

The C30 vacuum pump is a dry and contactless machine, enclosed in an acoustic sound shield, designed to have cooling air passed through the sound shield by a fan. The warm air is exhausted to the below compartment where the silencer is located. The C30 is built with modular construction consisting of two compartments: pumping and gear chambers separated by the use of labyrinth seals. In the pumping chamber, as two rotary claws rotate in opposite directions, the air is sucked in, compressed and discharged under pressure. In the gear chamber (box), two gears for synchronizing of the claws' rotation are lubricated with oil. The pumps are direct driven by a flanged motor via a coupling. The 4' aluminum check valve for anti suck back and inlet filter (flanged) can be installed separately. The C30 is well suited to use with Variable Frequency Controlled Drives for energy savings.

1.2 Unpacking & Storage

Inspect the box and vacuum 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 inlet and exhaust of the pump are covered with plastic caps to prevent dirt and other foreign substances from entering it. Leave these caps in place until you are ready to pipe the pump to your equipment.

The pump should be stored in a dry environment with normal air humidity (RH 0~80%, 14 to 140°F) for no more than 6 months.

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 inches of access around the pump to allow proper cooling. Also, adequate ventilation must be provided for cooling of the pump and motor.

Allow access to the oil sight glass in order to inspect the oil level regularly, and the oil fill and drain ports 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 as below:

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 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.

1.5 Vacuum Connections

Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in reduced pump capacity.

Pumps 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. The built-in anti-suck back valve should not be used as a shut-off valve for the vacuum system.

Remove the plastic protective cap from the inlet port prior to connection of pump to the system.

Should process gas contain dust or other foreign particles, a suitable inlet filter should be connected to the inlet port. Consult Ohio Medical for recommendations or refer to the 'Vacuum Pump Filters' tab at www.ohiomedicalparts.com.

The vacuum piping should be designed to ensure that no liquids such a condensate or liquid carried over from the process can reach the pump. If this possibility exists, a knock-out liquid separator should be installed. Consult Ohio Medical for recommendations or refer to the 'Vacuum Pump Filters' tab at www.ohiomedicalparts.com

The following flange sizes are standard on the pumps:

Table Caption: This table lists pump models along with their corresponding inlet and exhaust pipe sizes. The C30 model has a 4-inch inlet and a 4-inch exhaust.

1.6 Oil Filling on Gear Box

The pump is shipped without oil in the gear box. After level installation and correct rotation has been established, fill the pump
