APCO CAC-8000 Automatic Control Check Valve

Oil Filling Procedure (dashpot piping partially drained of oil)

Use "Mobil" DTE 24, Motor oil SAE 20 or Industrial oil #31.

1. Shut down pump.

2. Relieve Hydro-Pneumatic tank of any pressure, NOTE PRESSURE READING!

3. Make note of the setting of each Flow Control Valve, and then fully open each one to permit

filling the piping solid with oil.

4. Manually lift roller of the Timing Valve (#96) and hold in that position until Step 6.

5. Remove piping plugs in street elbows located on the side of the Hydro-Pneumatic tank and Oil

Reservoir and fill each tank slowly until oil level in the street elbow is visible, then replace pipe

plugs. DO NOT OVERFILL!

6. Release Cam Follower and re-set Flow Control Valves to original settings noted in step 3.

7. Re-pressurize the Hydro-Pneumatic tank to 15 psi or original pressure setting noted in step 2,

with a tire pump.

Oil Filling Procedure (dashpot piping completely drained of oil)

Follow steps 1 thru 5 above.

6. Loosen the 4 dashpot retaining bolts (#88) to allow the cylinder to be lifted approximately 3/8"

from its' mounting.

7. Manually lift dashpot cylinder or with the use of a tire pump, pressurize the Hydro-pneumatic

tank until the piston bottoms to the rod end of the cylinder. The cylinder head should move

approximately ¼" away from gear box.

8. Fill Oil Reservoir tank to proper level then replace pipe plug.

9. Relieve Hydro-pneumatic tank of air pressure and re-tighten 4 dashpot retaining bolts (#88).

10. Release Cam Follower and re-set Flow Control Valves to original settings, noted in step 3.

11. Re-pressurize Hydro-pneumatic tank to 15 psi with a tire pump.

Note: Before starting the pump, it is essential the APCO

Valve be manually or electrically opened and closed a few time to ensure the release of any

entrapped air in the oil system. Check oil levels and refill, if necessary. LACK OF OIL OR

PRESSENCE OF ENTRAPPED AIR IN PIPING SYSTEM CAN CAUSE ERRATIC OPERATION

OR SEVERE SLAM OF THE VALVE.
