INSTALLATION:
1. Depressurize and lockout air pressure.
2. Upstream pipes must be free of excessive dirt and liquids.
3. Install the Filter/Regulator as near as possible to the device it is to serve.
4. Install the Filter/Regulator so that air flows in direction of arrow on head.
5. The Filter/Regulator must be installed vertically with drain mechanism at the bottom.
6. The Filter/Regulator has gauge ports on both sides of the head. It is necessary to install a pressure gauge or pipe plugs into
each port before operating.
7. Filter-Regulators should be installed upstream of any Lubricators in the airline.
8. If installing using modular clamp connections A118-105 or A118-105M, torque screws 30-40 in-lbs.
OPERATION:
1. When adjusting pressure setting, always reset from a pressure lower than the final desired setting. For example, lowering
pressure from 100 psi to 50 psi should be done by decreasing pressure to 30 psi than increasing to 50 psi.
2. To increase pressure turn Adjusting Knob (2) clockwise, to lower pressure turn counter-clockwise.
3. Pull out Adjusting Key (1) for non-adjustment or remove for tamper proof.
4. For Manual Drain models: Periodically drain to discharge accumulated liquids by turning Drain Knob (32) clockwise.
5. For Automatic Drain models: Flexible tubing (3/16" ID) may be installed on the Drain Stem (34) to remove discharges. Turn
Drain Knob (32)counter-clockwise until it stops, push up to expose the Drain Clip. Remove Drain Clip (33) and Drain
Knob (32), and push tubing onto Drain Stem (34). The drain may be adjusted to compensate for differing operating
conditions by adjusting the Drain Knob (32). For low flow or low pressure drop, turn the Drain Knob (32) until the drain
just closes. For high flows or high pressure drop, turn the Drain Knob (32) clockwise if reduced drain action is required.
Turning the Drain Knob (32)clockwise to the stop puts the drain in a manual shutoff position. Turning the Drain Knob
(32) counter- clockwise will manually drain the filter.
6. Replace Plastic Bowls with Metal if any signs of crazing or cracking are observed.
7. Replace Element when dirty. If pressure differential reaches 8 psid, element MUST be replaced.
TO CLEAN OR REPAIR:
1. Depressurize and lockout air pressure.
2. Remove bowl Retaining Ring (21) and Bowl (29), including shatter guard (22) with plastic bowl, by turning counterclockwise.
3. Remove Lower Baffle (28) by turning counterclockwise.
4. The Filter Element (25) can now be removed. Do NOT clean elements, they must be replaced. Sintered Bronze elements may
be cleaned by soaking several hours in soap and water, then blowing them out in reverse direction to normal flow with
compressed air.
5. Remove Valve Cap (23) by turning counter-clockwise.
6. Valve Spring (18) and Valve (17) can now be removed. Visually inspect for defects, replace if needed.
7. To service Automatic Drain (30), turn Drain Knob (32) counterclockwise until it stops. Then push Drain Knob (32) up to
expose Drain Clip (33). Remove Drain Clip (33) and pull off Drain Knob (32).
8. Remove Drain Nut (31) by turning counterclockwise. The Automatic Drain (30) can now be removed from Bowl (29) and
disassembled.
9. The Automatic Drain (30) and Bowl (29) can now be cleaned.
10. To service Regulator side, reduce spring load to zero by turning Adjusting Knob (2) counter-clockwise.
11. Remove Dome (10) by turning counter-clockwise.
12. Diaphragm Assembly (11) can now be removed. Visually inspect for defects, replace if needed.
13. When re-assembling, be sure all o-rings are correctly located. Lubricate o-rings with Lithium grease. Torque Lower Baffle
(28) maximum 5 in-lbs. Torque Valve Cap (23) 55-65 in-lbs. Adjusting Washer (12) MUST be between Diaphragm
Assembly (11) and Dome (10). Torque Dome (10) 190-210 in-lbs. Torque Drain Nut (31) 5-15 in-lbs. Torque bowl
Retaining Ring (21) 30-50 in-lbs. When bowl Retaining Ring is fully in place, there should be a gap between the bowl
Retaining Ring (21) and Head (13) of 0.020"-0.040".
14. If the Filter-Regulator cannot be repaired by cleaning with soap and water, the parts should be replaced.
