Section 2 SET UP INSTRUCTIONS

The JWI filter press is normally shipped completely assembled and pre-tested. CAUTION: Use care in handling the filter press so as not to damage any components such as discharge extension pipes, plate handles, or hydraulic system. 1. Mount the filter press level to floor, platform, or extension legs through the base holes provided. NOTE: Press must be clamped up and square before exact dimension can be established. (See enclosed drawing) 2. Connect center inlet pipe to discharge of feed pump. (See enclosed filter pres s or manifold drawing) 3. Install drain pipe to bottom outlet of discharge m anifold. (See enclosed m anifold drawing) IMPORTANT! Be sure outlet of drain pipe is be low level of discharge manifold outlet. 4. If optional air blow down manifold is used, connect air supply as shown on manifold drawing. Use regulated air pressure 50 PS I maximum Automatic Closure Models O nly Connecting Air Supply Air supply to the JWI filter press should be clean, dry air at 125 PSI m aximum. NOTE: An air line drying system s hould be installed if high levels of mois ture are present in your air supply. This will prevent extensive dam age to the air circuit components in the system. 1. Connect air supply, using a minimum of 3/8" I.D. pipe, to fitting mark ed air inlet located at hydraulic cylinder end of filter press. NOTE: Use shut off valve in air line prior to filter press; air filt er and regulators are incorporated within the filter press system.

Section 3 OPERATION OF A FILTER PRESS AUTOMATIC CLOSURE

JWI uses an air over hydraulic s ystem to open and close the filter press. To close the filter press, air pressure is applied to the hydraulic fluid reservoir, forcing hydraulic fluid into the rear of the hydraulic cylinder, rapidly ex tending the ram. The hydraulic pump is then turned on to reach the maximum closing pressure. To open the filter press, the hy draulic pressure is release through a pilot operated valve. Air pressure is directed to the front of the hydraulic fluid bac k to the reservoir tank. To Close Filter Press 1. With air sup ply connected to filter press, line air pressure w ill register on gauge. 2. Turn s elector switch to close position. 3. Turn air supply switc h to on position. Regulated air pressure will register on gauge. Hydraulic cylinder will extend, closing the press. 4. Leave open-close selector switch in close position. With ram fully ex tended, turn hydraulic pump switch to on position. Leave hydraulic pump switch in on posit ion when press is in o peration. The hydraulic pump will engage, developing maxim um closing pressure on hydraulic gauge. NOTE: Small amounts of air esc aping momentarily from the hydraulic pum p prior to stroking is normal. If maximum hydraulic pressure (see s pecification page one) is not reached, follow the instruction titled "Regulated Air Pressure" on page 8. 5. Open inlet valve and start feed pump. With air diaphragm feed pump, cyc ling will show as press becomes filled. With air diaphragm feed pump cycling will slow as press becomes filled. With press completely filled, feed pump w ill stall. This usually occurs within 2 hours. 6. Turn off feed pump. This is done by shutting off its air supply. 7. Air blowdown (optional). Maximum pressure is 40 PSI. a. Close center inlet valve on line from feed pump. b. Close the three valves on discharge manifold. (See diagram #3.) c. Open air v alve on discharge manifold, expelling any w ater left in t he press (approximately 2 minutes or longer). d. Close air valve. e. Open the three valves on discharge manifold. Leave inlet valve closed. This will allow gravity drainage of press (app roximately 2 minutes).
