LIQUI/JECTOR
INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
INSTALLATION
The LIQUI/JECTOR is an in-line type filter and should be mounted in a vertical position in any horizontal run of compressed air, gas, or steam line. The head of the unit is marked showing the inlet and the outlet.
For draining a unit on intermittent service, a valve and dropleg are suitable. When the service is to be continuous, the use of a water trap is recommended for automatic liquid ejection. Further, on steam service, a steam trap is recommended.
The unit should be installed as near as possible to the point of use of the air, gas, or steam in order to minimize condensation beyond the LIQUI/JECTOR. If this is not practical, the LIQUI/JECTOR should be located at the lowest point, the coolest point, or other location of maximum conditions. The LIQUI/JECTOR should not be exposed to freezing conditions.
OPERATION
In the LIQUI/JECTOR, large slugs of liquid contaminant are removed by centrifugal force and a directional change before coming in contact with the separator filter element. The wet air, gas, or steam is then more completely stripped of liquid water, water-oil emulsions, free oil in droplet form, and entrained dirt by the separator filter element. This element is treated to render it hydrophobic (water repellent) and it will therefore not absorb liquid phases consisting of water and water-oil emulsions. Consequently, liquid droplets coalesce on the surface of the element and fall to the bottom of the unit, by gravity, where they are removed through the drain connection.
MAINTENANCE
Since there are no moving parts in the LIQUI/JECTOR, there is no wear. Maintenance consists only of the removal of accumulated dirt from the separator filter element. Periods of cleaning and changing of the element are determined by the conditions of use and regular inspections should therefore be made.
If the element needs cleaning, it may be soaked in most organic solvents, such as acetone, carbon tetrachloride, etc., without harmful effects. After such soaking it may be dried by blowing out with compressed air (an ultrasonic cleaner may also be used). Under no circumstances should the element be scraped or sandpapered.
WARNING: Before attempting to open housing, shut off steam, gas, or air supply and allow complete relief of pressure to prevent risk of personal injury.
Draw Bar Sealed Housings
1. Shut off steam, compressed gas, or air supply and relieve pressure from housing.
2. Remove casing nut and casing and remove wing nut.
3. Wear gloves to avoid contact with element surface, as oil from skin may contaminate the element’s coating. Remove the element by pulling it straight down.
4. Replace element O-ring as follows:
4.1 Be sure the old O-ring has been removed, and that the center rod is clear and free of any foreign particles, dirt, etc.
4.2 Apply a small amount of lubricant over the entire surface of the O-ring. Silicone O-ring lubricant, available from most industrial supply houses, is recommended.
4.3 Slide the O-ring over the threads and into the O-ring groove, being careful not to tear or damage the O-ring.
4.4 The O-ring should not be twisted when seated in the O-ring groove.
5. Wearing gloves, replace element gasket and push new element in place with slight twisting motion, securing with wing nut finger tight.
6. Replace vent screw washer.
7. Replace head gasket and casing nut sealing washer and secure casing back in place with casing nut. Maximum torque is 23 ft.-lbs.
Clamp Seal Housings
1. Shut off steam, compressed gas, or air supply and relieve pressure from housing.
2. Loosen clamp nut and remove clamp and casing.
3. Wear gloves to avoid contact with element surface, as oil from skin may contaminate the element’s coating. Loosen wing nut and remove the element by pulling it straight down.
4. Replace element O-rings as follows:
4.1 Be sure the old O-rings have been removed, and that the center rod is clear and free of any foreign particles, dirt, etc.
4.2 Apply a small amount of lubricant over the entire surface of the O-rings. Silicone O-ring lubricant, available from most industrial supply houses, is recommended.
4.3 Slide the O-rings over the threads and into the O-ring grooves, being careful not to tear or damage the O-rings.
4.4 The O-rings should not be twisted when seated in the O-ring groove.
5. Unscrew drawbolt from head and replace head drawbolt O-ring.
6. Screw drawbolt back into head.
7. Wearing gloves, replace element gasket and push new element in place with slight twisting motion, securing with wing nut finger tight.
8. Replace head O-ring and secure casing back in place with clamp. Maximum torque is 75 in.-lbs.
