8. On Economy Regulator units, tighten seat from 0.6 to 0.8 Nm (5 to 7 in-lbs).
On Mini Regulator and Filter / Regulator units, tighten seat to body from 0.9
to 1.1 Nm (8 to 10 in-lbs) of torque. Tighten bonnet onto body from 5.6 to
7.3 Nm (50 to 65 in-lbs) of torque.
9. Make sure that the control spring is still uncompressed before turning on
the
air supply. Turn on air supply, then slowly adjust the knob clockwise to
increase downstream pressure until the desired pressure has been reached.
10. To decrease regulator pressure setting, always reset from a pressure lower
than the final setting desired. For example, lowering the secondary pressure
from 550 to 410 kPa (80 to 60 PSIG) is best accomplished by dropping the
secondary pressure to 350 kPa (50 PSIG), then adjusting upward to
410 kPa (60 PSIG).
11. When the desired secondary pressure setting has been reached, push the
adjusting knob down to lock it.
12. Check for leaks. If leaks occur, shut off the air supply, exhaust system air
pressure, and make necessary adjustments to eliminate leakage.
Servicing Filter Element:
Note:
See Figure 1 to aid with this procedure.
1. Unscrew threaded bowl and element holder. Then remove filter element,
deflector, and gaskets.
2. Clean all internal parts, bowl, and body before re-assembling unit. See
Polycarbonate bowl cleaning section.
3. Install deflector, filter element, and gaskets.
4. Attach element holder. Torque 0.9 to 1.4 Nm (8 to 12 in-lbs).
5. To assist with retaining bowl’s o-ring while installing bowl, lubricate the o-ring
(with a mineral based oil or grease). Then place it on the bowl.
6. Screw bowl into body until it is stopped by body; then back off bowl 1/8 turn.
7. Apply pressure to the system and check for leaks. If leaks occur, shut off the
air supply, de-pressurize the system and make necessary adjustments to
eliminate leakage.
If you have questions concerning how to service this unit, contact your local
authorized dealer or your customer service representative.

SAFETY: Transparent Bowls
CAUTION
Polycarbonate bowls, being transparent and tough, are ideal for use with Filters
and Lubricators. They are suitable for use in normal industrial environments, but
should not be located in areas where they could be subject to direct sunlight, an
impact blow, nor temperatures outside of the rated range. As with most plastics,
some chemicals can cause damage. Polycarbonate bowls should not be exposed
to chlorinated hydrocarbons, ketones, esters and certain alcohols. They should
not be used in air systems where compressors are lubricated with fire resistant
fluids such as phosphate ester and di-ester types.
Metal bowls are recommended where ambient and/or media conditions are not
compatible with Polycarbonate bowls. Metal bowls resist the action of most such
solvents, but should not be used where strong acids or bases are present or in
salt laden atmospheres. Consult the factory for specific recommendations where
these conditions exist.
TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER ONLY!
DO NOT
use cleansing agents such as acetone, benzene, carbon tetrachloride,
gasoline, toluene, etc., which are damaging to this plastic.
Bowl guards are recommended for added protection of Polycarbonate bowls where
chemical attack may occasionally occur.
